    • The use of distance education using digital tools in higher education has increased over the last decade, particularly during the COVID-19 pandemic. Therefore, this study aimed to describe and evaluate nursing students' experiences of the pedagogical transition from traditional campus based learning to distance learning using digital tools.The nursing course Symptom and signs of illness underwent a transition from campus based education to distance learning using digital tools because of the COVID-19 pandemic. This pedagogical transition in teaching was evaluated using both quantitative and qualitative data analysis. Focus group interviews (n=9) were analysed using qualitative content analysis to explore students' experiences of the pedagogical transition and to construct a web-based questionnaire. The questionnaire comprised 14 items, including two open-ended questions. The questionnaire was delivered to all course participants and responses were obtained from 96 of 132 students (73%). Questionnaire data were analyzed using descriptive statistics and comments from the open-ended questions were used as quotes to highlight the quantitative data.The analysis of the focus group interviews extracted three main dimensions: didactic aspects of digital teaching, study environment, and students' own resources. Social interaction was an overall theme included in all three dimensions. Data from the questionnaire showed that a majority of students preferred campus based education and experienced deterioration in all investigated dimensions after the pedagogical transition. However, approximately one-third of the students appeared to prefer distance learning using digital tools.The main finding was that the pedagogical transition to distance education reduced the possibility for students' social interactions in their learning process. This negatively affected several aspects of their experience of distance learning using digital tools, such as reduced motivation. However, the heterogeneity in the responses suggested that a blended learning approach may offer pedagogical benefits while maintaining an advantageous level of social interaction.

  • The performance of EuroSCORE II in CABG patients in relation to sex, age, and surgical risk: a nationwide study in 14,118 patients
  • 2023
  • Ingår i: Journal of Cardiothoracic Surgery. - : Springer Science and Business Media LLC. - 1749-8090. ; 18:1
  • Tidskriftsartikel (refereegranskat)abstract
    • BackgroundTo determine the discriminative accuracy and calibration of EuroSCORE II in relation to age, sex, and surgical risk in a large nationwide coronary artery bypass grafting (CABG) cohort.MethodsAll 14,118 patients undergoing isolated CABG in Sweden during 2012-2017 were included. Individual patient data were taken from the SWEDEHEART registry. Patients were divided by age (< 60, 60-69, 70-79, >= 80 years), sex, and surgical risk (low: EuroSCORE < 4%, intermediate: 4-8%, high: > 8%). Discriminative accuracy was determined by the area under the receiver operating characteristic curve (AUC) and calibration by the observed/estimated (O/E) mortality ratio at 30 days.ResultsAUC and O/E ratio were 0.82 (95% CI 0.79-0.85) and 0.58 (0.50-0.66) overall, 0.82 (0.79-0.86) and 0.57 (0.48-0.66) in men, and 0.79 (0.73-0.85) and 0.60 (0.47-0.75) in women. Regarding age, discriminative accuracy was highest in patients aged 60-69 years (AUC: 0.86 [0.80-0.93]) but was satisfactory in all groups (AUC: 0.74-0.80). O/E ratio varied from 0.26 for patients > 60 years to 0.90 for patients > 80 years. Regarding surgical risk, AUC and O/E ratio were 0.63 (0.44-0.83) and 0.18 (0.09-0.30) in low-risk patients, 0.60 (0.55-0.66) and 0.57 (0.46-0.68) in intermediate-risk patients, and 0.78 (0.73-0.83) and 0.78 (0.64-0.92) in high-risk patients.ConclusionsEuroSCORE II had good discriminative accuracy independently of sex and age, but markedly overestimated mortality risk, especially in younger patients. Accuracy and calibration were better in high-risk patients than in low-risk and intermediate-risk patients.

  • Associations between medical therapy after surgical aortic valve replacement for aortic stenosis and long-term mortality: a report from the SWEDEHEART registry.
  • 2022
  • Ingår i: European heart journal. Cardiovascular pharmacotherapy. - : Oxford University Press (OUP). - 2055-6837 .- 2055-6845. ; 8:8, s. 837-846

    • The association between use of statins, renin-angiotensin system (RAS) inhibitors and/or β-blockers and long-term mortality in patients with aortic stenosis who underwent surgical aortic valve replacement (SAVR) is unknown.All patients with aortic stenosis who underwent isolated first time SAVR in Sweden from 2006 to 2017 and survived six months after discharge were included. Individual patient data from four mandatory nationwide registries were merged. Cox proportional hazards models, with time-updated data on medication status and adjusted for age, sex, comorbidities, type of prosthesis, and year of surgery, were used to investigate associations between dispensed statins, RAS inhibitors, and β-blockers, and all-cause mortality. In total, 9553 patients were included, and median follow-up time was 4.9 years (range 0-11); 1738 patients (18.2%) died during follow-up. Statins were dispensed to 49.1% and 49.0% of the patients within six months of discharge from hospital and after ten years, respectively. Corresponding figures were 51.4% and 53.9% for RAS inhibitors, and 79.3% and 60.7% for β-blockers. Ongoing treatment was associated with lower mortality risk for statins [adjusted hazard ratio (aHR) 0.67 (95% confidence interval 0.60-0.74), p<0.001] and RAS inhibitors [aHR 0.84 (0.76-0.93), p<0.001] but not for β-blockers [aHR 1.17 (1.05-1.30), p=0.004]. The associations were robust in subgroups based on age, sex, and comorbidities (p for interactions>0.05).The results of this large population-based real-world study support the use of statins and RAS inhibitors for patients who underwent SAVR due to aortic stenosis.

  • Sex differences in survival after myocardial infarction in Sweden, 1987-2010
  • 2017
  • Ingår i: Heart. - : BMJ. - 1355-6037 .- 1468-201X. ; 103:20, s. 1625-1630

    • Objective In this nationwide study, we investigated age-specific and sex-specific trends in sex differences in survival after acute myocardial infarction (AMI), including deaths from coronary heart disease (CHD) that occurred outside hospital. Methods Observational study in Sweden of 28-day and 1-year mortality among 658 110 persons (35.7% women) aged 35-84 years with a first-time CHD event 1987-2010 with data retrieved from the national Swedish death and hospital registries. Results Age-adjusted 28-day case fatality decreased from 23.5% to 8.5% over the period (p<0.05). In hospitalised cases, short-term survival in women aged 35-54 years compared with men of the same age was poorer, not changing appreciably over time (HRs for women relative to men 1.63 (95% CI 1.28 to 2.08) at age 35-54 years and 1.28 (95% CI 1.12 to 1.46) at age 55-64 years in 2005-2010), but after adjustment for comorbidities, differences between men and women were no longer significant (HR 1.25 (95% CI 0.97 to 1.61) and 1.05 (95% CI 0.91 to 1.20)). When CHD deaths outside hospital were included, women had better prognosis regardless of age and period. In patients surviving the first 28 days, age-adjusted 1-year case fatality decreased from 15.3% to 7.7% (p<0.05) for both men and women. After adjustment for comorbidities, no significant sex differences persisted below the age of 75 years in the last period. Female 28day survivors 75-84 years old had a consistently better prognosis than older men. Conclusions The worse short-term outcomes in women <55 years of age hospitalised with AMI did not persist after adjustment for comorbidities. When CHD deaths outside hospital were included, women had consistently better short-term prognosis. In 28-day survivors, women did not fare worse than men when differences in comorbidities were considered.

  • Absence of chest pain and long-term mortality in patients with acute myocardial infarction
  • 2018
  • Ingår i: Open Heart. - : BMJ. - 2053-3624. ; 5:2
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective Chest pain is the predominant symptom in patients with acute myocardial infarction (AMI). A lack of chest pain in patients with AMI is associated with higher in-hospital mortality, but whether this outcome is sustained throughout the first years after onset is unknown. Therefore, we aimed to investigate long-term mortality in patients hospitalised with AMI presenting with or without chest pain. Methods All AMI cases registered in the SWEDEHEART registry between 1996 and 2010 were included in the study. In total, we included 172 981 patients (33.5% women) with information on symptom presentation. Results Patients presenting without chest pain (12.7%) were older, more often women and had more comorbidities, prior medications and complications during hospitalisation than patients with chest pain. Short-term and long-term mortality rates were higher in patients without chest pain than in patients with chest pain: 30-day mortality, 945 versus 236/1000 person-years; 5-year mortality, 83 versus 21/1000 person-years in patients <65 years. In patients >= 65 years, 30-day mortality was 2294 versus 1140/1000 person-years; 5-year mortality, 259 versus 109/1000 person-years. In multivariable analysis, presenting without chest pain was associated with an overall 5-year HR of 1.85(95% CI 1.81 to 1.89), with a stronger effect in younger compared with older patients, as well as in patients without prior AMI, heart failure, stroke, diabetes or hypertension. Conclusion Absence of chest pain in patients with AMI is associated with more complications and higher short-term and long-term mortality rates, particularly in younger patients, and in those without previous cardiovascular disease.

  • Comparison of Midterm Outcomes Associated With Aspirin and Ticagrelor vs Aspirin Monotherapy After Coronary Artery Bypass Grafting for Acute Coronary Syndrome.
  • 2021
  • Ingår i: JAMA network open. - : American Medical Association (AMA). - 2574-3805. ; 4:8
  • Tidskriftsartikel (refereegranskat)abstract
    • Guidelines recommend dual antiplatelet therapy after coronary artery bypass grafting (CABG) for patients with acute coronary syndrome (ACS). However, the evidence for these recommendations is weak.To compare midterm outcomes after CABG in patients with ACS treated postoperatively with acetylsalicylic acid (ASA) and ticagrelor or with ASA monotherapy.This cohort study used merged data from several national registries of Swedish patients who were diagnosed with ACS and subsequently underwent CABG. All included patients underwent isolated CABG in Sweden between 2012 and 2017 with an ACS diagnosis less than 6 weeks before the procedure, survived 14 days after discharge from hospital, and were treated postoperatively with ASA plus ticagrelor or ASA monotherapy. A multivariable Cox regression model was used for the main analysis, and propensity score-matched models were performed as sensitivity analysis. Data were analyzed between May and September 2020.Postoperative antiplatelet treatment, defined as filled prescriptions, with either ASA and ticagrelor or ASA only.Major adverse cardiovascular events (MACE), defined as all-cause mortality, myocardial infarction, and stroke, and major bleeding, at 12 months and at the end of follow-up.A total of 6558 patients (5281 [80.5%] men; mean [SD] age at surgery, 67.6 [9.3] years) were included; 1813 (27.6%) were treated with ASA plus ticagrelor and 4745 (72.4%) were treated with ASA monotherapy. Crude MACE rate was 3.0 per 100 person years (95% CI, 2.5-3.6 per 100 person years) in the ASA plus ticagrelor group and 3.8 per 100 person years (95% CI, 3.5-4.1 per 100 person years) in the ASA group. After adjustment, there was no significant difference in MACE risk between ASA plus ticagrelor vs ASA only, neither during the first 12 months (adjusted hazard ratio [aHR], 0.84; 95% CI, 0.58-1.21; P=.34) or during total follow-up (aHR, 0.89; 95% CI, 0.71-1.11; P=.29). The use of ASA plus ticagrelor was associated with a significantly increased risk for major bleeding during the first 12 months (aHR, 1.90; 95% CI, 1.16-3.13; P=.011). Sensitivity analyses confirmed the results.In patients with ACS who survived 2 weeks after CABG, no significant difference in the risk of death or ischemic events could be demonstrated between ASA plus ticagrelor and patients treated with ASA only, while the risk for major bleeding was higher in patients treated with ASA plus ticagrelor. Sufficiently powered prospective randomized trials comparing different antiplatelet therapy strategies after CABG are warranted.

  • Postdischarge major bleeding, myocardial infarction, and mortality risk after coronary artery bypass grafting
  • 2023
  • Ingår i: HEART. - 1355-6037 .- 1468-201X.
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective To investigate the incidence and mortality risk associated with postdischarge major bleeding after coronary artery bypass grafting (CABG), and relate this to the incidence of, and mortality risk from, postdischarge myocardial infarction.Methods All patients undergoing first-time isolated CABG in Sweden in 2006-2017 and surviving 14 days after hospital discharge were included in a cohort study. Individual patient data from the SWEDEHEART Registry and five other mandatory nationwide registries were merged. Piecewise Cox proportional hazards models were used to investigate associations between major bleeding, defined as hospitalisation for bleeding, with subsequent mortality risk. Similar Cox proportional hazards models were used to investigate the association between postdischarge myocardial infarction and mortality risk.Results Among 36 633 patients, 2429 (6.6%) had a major bleeding event and 2231 (6.1%) had a myocardial infarction. Median follow-up was 6.0 (range 0-11) years. Major bleeding was associated with higher mortality risk <30 days (adjusted HR (aHR)=20.2 (95% CI 17.3 to 23.5)), 30-365 days (aHR=3.8 (95% CI 3.4 to 4.3)) and >365 days (aHR=1.8 (95% CI 1.7 to 2.0)) after the event. Myocardial infarction was associated with higher mortality risk <30 days (aHR=20.0 (95% CI 16.7 to 23.8)), 30-365 days (aHR=4.1 (95% CI 3.6 to 4.8)) and >365 days (aHR=1.8 (95% CI 1.7 to 2.0)) after the event.Conclusions The increase in mortality risk associated with a postdischarge major bleeding after CABG is substantial and is similar to the mortality risk associated with a postdischarge myocardial infarction.

  • Secondary prevention medications after coronary artery bypass grafting and long-term survival : a population-based longitudinal study from the SWEDEHEART registry.
  • 2019
  • Ingår i: European Heart Journal. - : Oxford University Press. - 0195-668X .- 1522-9645. ; 41:17, s. 1653-1661
  • Tidskriftsartikel (refereegranskat)abstract
    • AIMS: To evaluate the long-term use of secondary prevention medications [statins, β-blockers, renin-angiotensin-aldosterone system (RAAS) inhibitors, and platelet inhibitors] after coronary artery bypass grafting (CABG) and the association between medication use and mortality.METHODS AND RESULTS: All patients who underwent isolated CABG in Sweden from 2006 to 2015 and survived at least 6 months after discharge were included (n = 28 812). Individual patient data from SWEDEHEART and other mandatory nationwide registries were merged. Multivariable Cox regression models using time-updated data on dispensed prescriptions were used to assess associations between medication use and long-term mortality. Statins were dispensed to 93.9% of the patients 6 months after discharge and to 77.3% 8 years later. Corresponding figures for β-blockers were 91.0% and 76.4%, for RAAS inhibitors 72.9% and 65.9%, and for platelet inhibitors 93.0% and 79.8%. All medications were dispensed less often to patients ≥75 years. Treatment with statins [hazard ratio (HR) 0.56, 95% confidence interval (95% CI) 0.52-0.60], RAAS inhibitors (HR 0.78, 95% CI 0.73-0.84), and platelet inhibitors (HR 0.74, 95% CI 0.69-0.81) were individually associated with lower mortality risk after adjustment for age, gender, comorbidities, and use of other secondary preventive drugs (all P < 0.001). There was no association between β-blockers and mortality risk (HR 0.97, 95% CI 0.90-1.06; P = 0.54).CONCLUSION: The use of secondary prevention medications after CABG was high early after surgery but decreased significantly over time. The results of this observational study, with inherent risk of selection bias, suggest that treatment with statins, RAAS inhibitors, and platelet inhibitors is essential after CABG whereas the routine use of β-blockers may be questioned.

  • Is blood a necessary component of the perfusate during isolated limb perfusion - a randomized controlled trial
  • 2019
  • Ingår i: International Journal of Hyperthermia. - : Informa UK Limited. - 0265-6736 .- 1464-5157. ; 36:1, s. 794-800
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Isolated limb perfusion (ILP) is a treatment option for malignancies localized to an extremity and is performed by surgical isolation of the limb which is connected to an extracorporeal circulation system. A high concentration of a chemotherapeutic agent is perfused through the limb, while systemic toxicity is avoided. Currently, the use of packed red blood cells in the priming solution is the norm during ILP. The aim of this study was to investigate the possibility to replace an erythrocyte-based prime solution with a crystalloid-based prime solution while maintaining the regional metabolic oxygen demand during ILP. Methods: In a single-center, randomized controlled, non-blinded, non-inferiority clinical trial, 21 patients scheduled for treatment with ILP were included and randomized 1:1 to either an erythrocyte-based prime solution (control) or a crystalloid-based prime solution (intervention). Results: There was a significant difference in lactate level (mmol/L) during the perfusion between the intervention group and the control group (1.6 +/- 0.4 vs. 3.6 +/- 0.7, p = .001). No significant differences in oxygen extraction (%) (22 +/- 11 vs. 14 +/- 4, p = .06), oxygen delivery (ml/min) (90 +/- 49 vs. 108 +/- 38, p = .39), oxygen consumption (ml/min) (14 +/- 2 vs. 14 +/- 5, p = .85), regional central venous saturation (%) (83 +/- 10 vs. 91 +/- 4, p = .07) or INVOS (%) (76 +/- 14 vs. 81 +/- 11, p = .42) were found between the intervention group and the control group. Conclusion: This study showed no significant improvement with the addition of packed red blood cells into the prime solution in ensuring the metabolic oxygen demand in the treated extremity during ILP, and we, therefore, recommend that a crystalloid-based prime solution should be used.

  • Coronary Artery Bypass Grafting in Women 50 Years or Younger
  • 2019
  • Ingår i: Journal of the American Heart Association. - : Ovid Technologies (Wolters Kluwer Health). - 2047-9980. ; 8:18
  • Tidskriftsartikel (refereegranskat)abstract
    • Background-Prior research has shown higher mortality in women with severe coronary artery disease compared with men, particularly in younger patients. It is unknown if this could be attributable to an adverse risk factor profile. Methods and Results-In a population-based cohort study, we included all adults <= 50 years of age (932 women and 4514 men) who underwent coronary artery bypass grafting from 1995 to 2013 from the SWEDEHEART (Swedish Web System for Enhancement and Development of Evidence-Based Care in Heart Disease Evaluated According to Recommended Therapies) register. Following inverse probability of treatment weighting, we investigated differences between women and men. Women had a higher prevalence of cardiovascular risk factors compared with men. There was no difference in early mortality between women and men (unadjusted: 1.3% versus 0.9%; hazard ratio, 1.42; 95% CI, 0.75-2.70; weighted sample: 1.1% versus 1.0%; hazard ratio, 1.10; 95% CI, 0.52-2.30). During a median follow-up time of 11.8 years, in the unweighted population, the risk of death was greater in women compared with men (hazard ratio, 1.34; 95% CI, 1.13-1.58). However, in the weighted sample, the risk of death was not significantly different in women compared with men (hazard ratio, 1.02; 95% CI, 0.83-1.26). Conclusions-Women <= 50 years of age had a higher unadjusted risk of death after coronary artery bypass grafting compared with men, but this was explained by a clustering of cardiovascular risk factors. Female sex per se was not associated with increased mortality or major adverse cardiovascular events. Early mortality was not increased in women compared with men, even though younger women in our study had an increased burden of risk factors known to affect early risk.

  • Long-term trends in the prevalence of patients hospitalized with ischemic stroke from 1995 to 2010 in Sweden
  • 2017
  • Ingår i: Plos One. - : Public Library of Science (PLoS). - 1932-6203. ; 12:6
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective The prevalence of stroke is expected to increase partly because of prolonged life expectancy in the general population. The objective of this study was to investigate trends in the prevalence of patients hospitalized with ischemic stroke (IS) in Sweden from 1995-2010. The Swedish inpatient and cause-specific death registries were used to estimate the absolute numbers and prevalence of patients who were hospitalized with and survived an IS from 1995-2010. The overall number of IS increased from 129,418 in 1995 to 148,778 in 2010. In 1995, the prevalence of IS was 189 patients per 10,000 population. An increase in overall prevalence was observed until 2000, and then it remained stable, followed by a decline with an annual percentage change of (APC)-0.8% (95% CI -1.0 to 0.6) and with a final prevalence of 199 patients per 10,000 population in 2010. The prevalence of IS in people aged <45 years increased from 6.4 in 1995 to 7.6 patients per 10,000 population in 2010, with an APC of 2.1% (95% CI 0.9 to 3.4) from 1995-1998 and 0.7% (95% CI 0.6-0.9) from 1998-2010. Among those aged 45-54 years, the prevalence rose through the mid to late 1990s, followed by a slight decrease (APC:-0.7%, 95% CI -1.1 to -0.4) until 2006 and then remained stable with a prevalence of 43.8 patients per 10,000 population in 2010. Among >= 85 years, there was a minor decrease (APC: -0.3%, 95% CI -0.5 to -0.1) in overall prevalence after 2002 from 1481 to 1453 patients per 10,000 population in 2010. The overall prevalence of IS increased until 2000, but then remained stable followed by a slight decline. However, the prevalence of IS in the young increased through the study period. The absolute number of IS survivors has markedly increased, mainly because of demographic changes.

  • The risk of dementia after coronary artery bypass grafting in relation to age and sex
  • 2021
  • Ingår i: Alzheimers & Dementia. - : Wiley. - 1552-5260 .- 1552-5279. ; 17:6, s. 1042-1050

    • Introduction We examined the long-term risk of dementia after coronary artery bypass grafting (CABG) in relation to age and sex. Methods All CABG patients in Sweden 1992-2015 (n = 111,335), and matched controls (n = 222,396) were included in a population-based study. Adjusted hazard ratios (aHR) for all-cause dementia, vascular dementia, and Alzheimer's disease were calculated. Results There was no difference in the risk for all-cause dementia between CABG patients and control subjects (aHR 0.98 [95% confidence interval 0.95 to 1.02]). CABG patients <65 years and 65 to 74 years had higher risk (aHR 1.29 [1.17-1.42] and 1.08 [1.02-1.13], respectively), and patients >= 75 years had lower risk (aHR 0.76 [0.71-0.81]). The highest risk was observed in women <65 years (aHR 1.64 [1.31-2.05]). Discussion Overall, the long-term risk for all-cause dementia does not differ between CABG patients and the general population. Younger patients have a higher risk, while older patients have a lower risk, compared to controls.

  • Trends in risk of recurrence after the first ischemic stroke in adults younger than 55 years of age in Sweden
  • 2016
  • Ingår i: International Journal of Stroke. - : SAGE Publications. - 1747-4930 .- 1747-4949. ; 11:1, s. 52-61
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Previous studies on stroke recurrence in younger adults often contain small sample size which makes it difficult to study trends in stroke recurrence over a long period of time. Aims: The aim of the present study was to investigate temporal trends in the risk of recurrence in younger patients with a first ischemic stroke. Methods: All men and women aged 18-54 years who had survived at least 28 days after a first ischemic stroke from 1987 to 2006 were identified in the Swedish Inpatient Register. The patients were stratified into four 5-year periods according to their admission period and were followed up for a total of four years after the index event with regard to recurrent ischemic stroke. A Cox regression model was used to analyze the risk of recurrent ischemic stroke. Results: Of the 17,149 ischemic stroke patients who were identified, 2432 (14.2%) had a recurrent ischemic stroke event within four years. From the first to the last periods (1987-1991 versus 2002-2006), the four-year risk of recurrent ischemic stroke decreased by 55% (hazard ratio 0.45, 95% confidence interval 0.39-0.53) in men and 59% (hazard ratio 0.41, 95% confidence interval, 0.33-0.50) in women. The cumulative four-year risk was 11.8% (95% CI 10.55-13.25) in men and 9.8% (95% CI 8.40-11.46) in women during the last five-year period (2002-2006). Conclusions: The risk of recurrence among younger ischemic stroke patients has decreased over the past 20 years. Despite these improvements, younger patients are still at a high risk for recurrent ischemic stroke.

    • Studies indicate that the time from onset of symptoms to medical treatment has decreased in acute myocardial infarction (AMI). However, there are still variations indicating that women wait longer than men before making the decision to seek medical care. Multidimensional factors hindering and facilitating the decision have been identified in previous studies, though few have fully explored how social context affects women's expectations, interpretations and actions and so influences the decision-making process. The aim of this study was therefore to identify how women's experiences interacted and influenced the decision to seek medical care at their first AMI. Seventeen women, aged 38-75 years, were interviewed, at home or in the hospital, between June 2011 and May 2012. Grounded theory was used as a method, and data collection and analysis were carried out simultaneously. The results showed that before deciding to seek medical care, these women went through three defined but interrelated processes that together hindered their normal activities and made them act according to existential needs. The women's experiences of the progression of the disease, in terms of both symptoms and time, were very different, so they sought medical care at different times, sometimes life-threateningly late and sometimes before developing an AMI. Three mechanisms had to coincide if the women were to receive medical care. First, the women had to acknowledge their symptoms as something more than common bodily changes. Second, the healthcare system had to be accessible when the women made their decision to seek care. Third, the women must have come into contact with healthcare providers when the heart muscle had taken enough damage to measure.

  • Long-term outcome of patients undergoing re-exploration for bleeding following cardiac surgery: a SWEDEHEART study
  • 2022
  • Ingår i: European Journal of Cardio-Thoracic Surgery. - : Oxford University Press (OUP). - 1010-7940 .- 1873-734X. ; 62:5
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVES: Excessive bleeding leading to re-exploration is a severe complication of cardiac surgical procedures, associated with early postoperative morbidity and mortality. Less is known about the long-term outcome of these patients. We evaluated the impact of re-exploration after cardiac surgery on peri- and postoperative morbidity and mortality, as well long-term mortality, in a well-defined nationwide population. METHODS: In this retrospective study, 48 060 consecutive patients undergoing coronary artery bypass grafting (CABG) and/or valve surgery from 2006 to 2015 were analysed. Multivariable logistic regression was used to identify factors associated with re-exploration, morbidity and mortality. Cox regression analysis was implemented to explore the association between re-exploration and long-term mortality. The mean follow-up time was 4.6 years (range 0-10 years) with follow-up time set at 31 December 2015. RESULTS: Overall, 2371 patients (4.9%) underwent re-exploration. Factors associated with re-exploration included advanced age, procedures other than isolated CABG and acute surgery. Re-explored patients had an increased risk of unadjusted mortality at 30, 90 and beyond 90 days (all P < 0.001). Significance was maintained after adjustment at 30 days [odds ratio: 3.94, 95% confidence interval (CI): 3.19-4.85, P < 0.001] and 90 days (odds ratio: 3.79, 95% CI: 3.14-4.55, P < 0.001), but not with long-term mortality (hazard ratio: 1.02, 95% CI: 0.91-1.15, P= 0.712). Furthermore, re-exploration was independently associated with other postoperative complications, e.g. prolonged hospital stay, stroke and renal injury. CONCLUSIONS: Patients who are re-explored for bleeding within 24 h have almost four-fold higher odds of mortality within 3 months post-procedure. However, the increased risk of death following re-exploration is not maintained in the long term.

    • New-onset postoperative atrial fibrillation (POAF) occurs in approximately 30% of patients undergoing coronary artery bypass grafting (CABG). It is unknown whether early recurrence is associated with worse outcomes.To test the hypothesis that early AF recurrence in patients with POAF after CABG is associated with worse outcomes.This Swedish nationwide cohort study used prospectively collected data from the SWEDEHEART (Swedish Web System for Enhancement and Development of Evidence-Based Care in Heart Disease Evaluated According to Recommended Therapies) registry and 3 other mandatory national registries. The study included patients who underwent isolated first-time CABG between January 1, 2007, and December 31, 2020, and developed POAF. Data analysis was performed between March 6 and September 16, 2023.Early AF recurrence defined as an episode of AF leading to hospital care within 3 months after discharge.The primary outcome was all-cause mortality. Secondary outcomes included ischemic stroke, any thromboembolism, heart failure hospitalization, and major bleeding within 2 years after discharge. The groups were compared with multivariable Cox regression models, with early AF recurrence as a time-dependent covariate. The hypothesis tested was formulated after data collection.Of the 35329 patients identified, 10609 (30.0%) developed POAF after CABG and were included in this study. Their median age was 71 (IQR, 66-76) years. The median follow-up was 7.1 (IQR, 2.9-9.0) years, and most patients (81.6%) were men. Early AF recurrence occurred in 6.7% of patients. Event rates (95% CIs) per 100 patient-years with vs without early AF recurrence were 2.21 (1.49-3.24) vs 2.03 (1.83-2.25) for all-cause mortality, 3.94 (2.92-5.28) vs 2.79 (2.56-3.05) for heart failure hospitalization, and 3.97 (2.95-5.30) vs 2.74 (2.51-2.99) for major bleeding. No association between early AF recurrence and all-cause mortality was observed (adjusted hazard ratio [AHR], 1.17 [95% CI, 0.80-1.74]; P=.41). In exploratory analyses, there was an association with heart failure hospitalization (AHR, 1.80 [95% CI, 1.32-2.45]; P=.001) and major bleeding (AHR, 1.92 [1.42-2.61]; P<.001).In this cohort study of early AF recurrence after POAF in patients who underwent CABG, no association was found between early AF recurrence and all-cause mortality. Exploratory analyses showed associations between AF recurrence and heart failure hospitalization, oral anticoagulation, and major bleeding.

    • OBJECTIVES Perioperative stroke is a severe complication of cardiac surgery. We assessed the incidence of stroke over time, the association between stroke and mortality and identified preoperative factors independently associated with perioperative stroke, in a large nationwide cardiac surgery population. METHODS All patients who underwent coronary artery bypass grafting in Sweden 2006-2017 were included in a registry-based observational cohort study based on prospectively collected data. Multivariable logistic and Cox regression models were used to assess associations between perioperative stroke and mortality and to identify factors associated with stroke. The median follow-up was 6 years (range 0-12). RESULTS There were 441 perioperative strokes in 36 898 patients. The mean incidence was 1.2% and decreased marginally over time [adjusted odds ratio (OR) 0.97 per year (95% confidence interval 0.94-1.00), P = 0.035]. Stroke patients had a higher overall mortality risk during follow-up [adjusted hazard ratio 2.30 (2.00-2.64), P < 0.001], with the highest risk during the first 30 postoperative days [adjusted hazard ratio (7.29 (5.58-9.54), P < 0.001]. The strongest independent preoperative factors associated with stroke were prior cardiac surgery [adjusted OR 2.89 (1.40-5.96)], critical preoperative condition [adjusted OR 2.55 (1.73-3.76)], previous stroke [adjusted OR 1.77 (1.35-2.33)], preoperative angina requiring intravenous nitrates [adjusted OR 1.67 (1.28-2.17)], peripheral vascular disease [OR 1.63 (1.25-2.13)] and advanced age [OR 1.05 (1.03-1.06) per year]. CONCLUSIONS The incidence of perioperative stroke after coronary artery bypass grafting has remained stable. Patients with perioperative stroke had a markedly higher adjusted risk of death early after surgery. The risk declined over time but remained higher during the entire follow-up period.

    • OBJECTIVES: Deep sternal wound infection (DSWI) is a serious complication after open-heart surgery. We investigated the association between DSWI and short- and long-term all-cause mortality in a large well-defined nationwide population. METHODS: A retrospective, nationwide cohort study, which included 114676 consecutive patients who underwent coronary artery bypass grafting (CABG) and/or valve surgery from 1997 to 2015 in Sweden. Short- and long-term mortality was compared between DSWI patients and non-DSWI patients using propensity score inverse probability weighting adjustment based on patient characteristics and comorbidities. Median follow-up was 8.0 years (range 0-18.9). RESULTS: Altogether, 1516 patients (1.3%) developed DSWI, most commonly in patients undergoing combined CABG and valve surgery (2.1%). DSWI patients were older and had more disease burden than non-DSWI patients. The unadjusted cumulative mortality was higher in the DSWI group compared with the non-DSWI group at 90 days (7.9% vs 3.0%, P < 0.001) and at 1 year (12.8% vs 4.5%, P < 0.001). The adjusted absolute difference in risk of death was 2.3% [95% confidence interval (CI): 0.8-3.9] at 90 days and 4.7% (95% CI: 2.6-6.7) at 1 year. DSWI was independently associated with 90-day [adjusted relative risk (aRR) 1.89 (95% CI: 1.38-2.59)], 1-year [aRR 2.13 (95% CI: 1.68-2.71)] and long-term all-cause mortality [adjusted hazard ratio 1.56 (95% CI: 1.30-1.88)]. CONCLUSIONS: Both short- and long-term mortality risks are higher in DSWI patients compared to non-DSWI patients. These results stress the importance of preventing these infections and careful postoperative monitoring of DSWI patients.

    • Aortic stenosis is the most common valvular disease, and its prevalence is increasing due to the ageing population. Transcatheter aortic valve replacement (TAVR) is the recommended method when treating frail, older patients. Knowledge of what motivates older patients to undergo TAVR is important, in order to meet patients' expectations.The study aimed to explore the meaning of older patients' motivation to undergo TAVR.The design was a qualitative study, analysed using a phenomenological hermeneutic approach. In-depth, semi-structured interviews with open-ended questions were conducted. Participants were selected from a specialist cardiology clinic in Sweden. Eighteen patients, six women and twelve men, aged 66-92, were recruited.The analysis showed that patients who had agreed to undergo TAVR were deeply affected by their body's failure. Before the TAVR procedure, the participants were limited in their daily activities and experienced that their life was on hold. They experienced that they were barely existing. They were aware of their life-threatening condition and were forced to confront death. Yet despite an advanced age, they still had considerable zest for life. It was very important to them to remain independent in everyday life, and fear of becoming dependent had a strong impact on their motivations for undergoing TAVR.Older patients' motivations to undergo TAVR are strongly influenced by their fear of being dependent on others and their zest for life. Health care professionals need to support these patients in setting realistic and personalised goals.Person-centered care actions could facilitate patients' involvement in the decision about TAVR and strenghten patients' beliefs in their own capabilities, before and after TAVR.

  • Socioeconomic factors and long-term mortality risk after surgical aortic valve replacement.

  • Tidskriftsartikel (refereegranskat)abstract
    • There is scarce knowledge about the association between socioeconomic status and mortality in patients undergoing surgical aortic valve replacement. This study explores the associations between income, education and marital status, and long-term mortality risk.In this national registry-based observational cohort study we included all 14,537 patients aged >18 years who underwent isolated surgical aortic valve replacement for aortic stenosis in Sweden 1997-2020. Socioeconomic status and comorbidities were collected from three mandatory national registries. Cox regression models adjusted for patient characteristics and comorbidities were used to estimate the mortality risk.Mortality risk was higher for patients in the lowest versus the highest income quintile (adjusted hazard ratio [aHR] 1.36, 95% confidence interval [CI]: 1.11-1.65), for patients with <10 years education versus >12 years (aHR 1.20, 95% CI:1.08-1.33), and for patients who were not married/cohabiting versus those who were (aHR 1.24, 95% CI:1.04-1.48). Patients with the most unfavorable socioeconomic status (lowest income, shortest education, never married/cohabiting) had an adjusted median survival of 2.9 years less than patients with the most favorable socioeconomic status (14.6 years, 95% CI: 13.2-17.4 years vs. 11.7 years, 95% CI: 9.8-14.4).Low socioeconomic status in patients undergoing surgical aortic valve replacement is associated with shorter survival and an increased long-term adjusted mortality risk. These results emphasize the importance of identifying surgical aortic valve replacement patients with unfavorable socioeconomic situation and ensure sufficient post-discharge surveillance.

    • Beta blockers are associated with improved outcomes for selected patients with cardiovascular disease. We assessed long-term utilization of beta blockers after coronary artery bypass grafting (CABG) and its association with outcome.All 35,184 patients in Sweden who underwent first-time isolated CABG between 1 January 2006 and 31 December 2017 and were followed for at least 6 months were included in a nationwide observational study. Multivariable Cox regression models using time-updated data on dispensed prescriptions were used to assess associations between different types of beta blockers and outcome. The primary outcome was major adverse cardiovascular events (MACE), a composite of all-cause mortality, stroke and myocardial infarction (MI). Subgroup analyses were performed in patients with and without previous MI, heart failure, and reduced left ventricular ejection fraction (LVEF). Median follow-up was 5.2 years (range 0-11).At baseline, 33,159 (94.2%) of the patients were dispensed beta blockers, 32,225 (91.6%) of which were cardioselective beta blockers. After 10 years, the dispense of cardioselective beta blockers had declined to 73.7% of all patients. Ongoing treatment with cardioselective beta blockers was associated with a slight reduction in MACE (hazard ratio (HR) 0.93, 95% confidence interval (CI) 0.89-0.98, p = 0.0063). The reduction was largely driven by a reduced risk of MI (HR 0.83, 95% CI 0.75-0.92, p = 0.0003), while there was no significant reduction in all-cause mortality (HR 0.99, 95% CI 0.93-1.05) and stroke (HR 0.96, 95% CI 0.87-1.05). The reduced risk for MI was consistent in all investigated subgroups.Ongoing treatment with cardioselective beta blockers after CABG is associated with a reduction in MACE, mainly because of reduced long-term risk for MI. The association between cardioselective beta blockers and MI was consistent in patients with and patients without previous MI, heart failure, atrial fibrillation, or reduced LVEF.

    • The TACSI trial (ClinicalTrials.gov Identifier: NCT03560310) tests the hypothesis that 1-year treatment with dual antiplatelet therapy with acetylsalicylic acid (ASA) and ticagrelor is superior to only ASA after isolated coronary artery bypass grafting (CABG) in patients with acute coronary syndrome. The TACSI trial is an investor-initiated pragmatic, prospective, multinational, multicenter, open-label, registry-based randomized trial with 1:1 randomization to dual antiplatelet therapy with ASA and ticagrelor or ASA only, in patients undergoing first isolated CABG, with a planned enrollment of 2200 patients at Nordic cardiac surgery centers. The primary efficacy end point is a composite of time to all-cause death, myocardial infarction, stroke, or new coronary revascularization within 12 months after randomization. The primary safety end point is time to hospitalization due to major bleeding. Secondary efficacy end points include time to the individual components of the primary end point, cardiovascular death, and rehospitalization due to cardiovascular causes. High-quality health care registries are used to assess primary and secondary end points. The patients will be followed for 10 years. The TACSI trial will give important information useful for guiding the antiplatelet strategy in acute coronary syndrome patients treated with CABG.

    • Surgical risk, age, perceived life expectancy, and valve durability influence the choice between surgical aortic valve replacement (SAVR) and transcatheter aortic valve implantation. The contemporaneous life expectancy after SAVR, in relation to surgical risk and age, is unknown.The purpose of this study was to determine median survival time in relation to surgical risk and chronological age in SAVR patients.Patients≥60 years with aortic stenosis who underwent isolated SAVR with a bioprosthesis (n=8,353) were risk-stratified before surgery into low, intermediate, or high surgical risk using the logistic EuroSCORE (2001-2011) or EuroSCORE II (2012-2017) and divided into age groups. Median survival time and cumulative 5-year mortality were estimated with Kaplan-Meier curves. Cox regression analysis was used to further determine the importance of age.There were 7,123 (85.1%) low-risk patients, 942 (11.3%) intermediate-risk patients, and 288 (3.5%) high-risk patients. Median survival time was 10.9 years (95% confidence interval: 10.6-11.2 years) in low-risk, 7.3 years (7.0-7.9years) in intermediate-risk, and 5.8 years (5.4-6.5 years) in high-risk patients. The 5-year cumulative mortality was 16.5% (15.5%-17.4%), 30.7% (27.5%-33.7%), and 43.0% (36.8%-48.7%), respectively. In low-risk patients, median survival time ranged from 16.2 years in patients aged 60 to 64 years to 6.1 years in patients aged≥85 years. Age was associated with 5-year mortality only in low-risk patients (interaction P< 0.001).Eighty-five percent of SAVR patients receiving bioprostheses have low surgical risk. Estimated survivalis substantial following SAVR, especially in younger, low-risk patients, which should be considered in Heart Teamdiscussions.

    • The optimal medical therapy after surgical aortic valve replacement (SAVR) for aortic stenosis remains unknown. Renin-angiotensin system (RAS) inhibitors could potentially improve cardiac remodelling and clinical outcomes after SAVR.All patients undergoing SAVR due to aortic stenosis in Sweden 2006-2020 and surviving 6 months after surgery were included. The primary outcome was major adverse cardiovascular events (MACEs; all-cause mortality, stroke or myocardial infarction). Secondary endpoints included the individual components of MACE and cardiovascular mortality. Time-updated adjusted Cox regression models were used to compare patients with and without RAS inhibitors. Subgroup analyses were performed, as well as a comparison between angiotensin-converting enzyme (ACE) inhibitors and angiotensin II receptor blockers (ARBs).A total of 11894 patients (mean age, 69.5 years, 40.4%women) were included. Median follow-up time was 5.4 (2.7-8.5) years. At baseline, 53.6% of patients were dispensed RAS inhibitors, this proportion remained stable during follow-up. RAS inhibition was associated with a lower risk of MACE (adjusted hazard ratio (aHR) 0.87 (95% CI 0.81 to 0.93), p<0.001), mainly driven by a lower risk of all-cause death (aHR 0.79 (0.73 to 0.86), p<0.001). The lower MACE risk was consistent in all subgroups except for those with mechanical prostheses (aHR 1.07 (0.84 to 1.37), p for interaction=0.040). Both treatment with ACE inhibitors (aHR 0.89 (95% CI 0.82 to 0.97)) and ARBs (0.87 (0.81 to 0.93)) were associated with lower risk of MACE.The results of this study suggest that medical therapy with an RAS inhibitor after SAVR is associated with a 13% lower risk of MACE and a 21% lower risk of all-cause death.

  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Renin-angiotensin system (RAS) inhibitors are recommended postoperatively to coronary artery bypass grafting (CABG) patients with reduced left ventricular function, diabetes, hypertension or previous myocardial infarction, but not to remaining patients. The aim of the study was to assess the long-term utilization of RAS inhibitors after CABG in patients with and without indication for treatment, and its association with outcome. Methods: All patients (n = 28,782) not meeting exclusion criterion in Sweden who underwent isolated first time CABG from 2006 to 2015 were included using nationwide registries. The association between treatment and outcome was assessed using adjusted Cox regression models with time-updated data on medications. The primary outcome was major adverse cardiovascular events (MACE), defined as all-cause mortality, stroke and/or myocardial infarction. Results: At baseline 26,284 (91.3%) of the patients had at least one indication for RAS inhibition while 2498 (8.7%) had not. RAS inhibitors were dispensed to 77.0% and 29.7% of patients with and without indication respectively. Dispense declined over time. RAS inhibition was associated with a reduction in MACE in the whole study population (adjusted hazard ratio (aHR) 0.88, 95% confidence interval (95% CI) 0.83–0.93, p < 0.0001), and in patients with (aHR 0.87 95% CI: 0.82–0.93, p < 0.0001) and without indication (aHR 0.75, 95% CI: 0.58–0.98, p = 0.034). Conclusions: RAS inhibition is underutilized after CABG. The use of RAS inhibitors was associated with a reduction in MACE, both in patients with and without indication for treatment. The results suggest that RAS inhibition is beneficial for all CABG patients. Randomized controlled trials are necessary to confirm this hypothesis. © 2021 The Authors

    • To explore the currently unknown association between history of cancer at the time of coronary artery bypass grafting (CABG) and long-term survival.All patients (n=82,137) undergoing isolated first-time CABG in Sweden during 1997-2015 were included in this retrospective population-based cohort study. Individual patient data from the SWEDEHEART registry and 4 other mandatory nationwide health care registries were merged. Multivariable Cox proportional hazards regression and competing risk models adjusted for age and gender were used to assess associations between history of cancer, and long-term all-cause, cardiovascular and cancer mortality. Median follow-up was 9.0years (interquartile range, 4.8-13.1).Altogether, 6819 (8.3%) of the patients had a history of cancer. The annual prevalence increased from 3.8% in 1997 to 14.8% in 2015. Patients with a history of cancer were older (72 vs 66years; P<.001) and had more comorbidities. Long-term all-cause mortality was significantly greater in patients with a history of cancer (45.7% vs 22.9% at 10years; adjusted hazard ratio, 1.33; 95% confidence interval [CI], 1.28-1.38, P<.001). According to the competing risk models, history of cancer was associated with an increased risk for cancer death (subdistribution hazard ratio, 2.45; 95% CI, 2.28-2.63, P<.001) but not cardiovascular death (subdistribution hazard ratio, 0.88; 95% CI, 0.83-0.94, P<.001).The proportion of patients undergoing CABG with a history of cancer has increased over time. History of cancer at the time of surgery is associated with increased cancer deaths over time but not cardiovascular deaths. The same cardiovascular prognosis after CABG can be expected regardless of cancer history.

    • In this study, e-learning based on authentic situations was used as a pedagogic method to stimulate medi-cal students to reflect over their own learning styles and to prepare them for dealing with medical insur-ance issues in their future profession. The aim was to explore the learning styles used by the students in a Social medicine course when e-learning, based on authentic situations was used as a pedagogical ap-proach. A learning style questionnaire by Kember, Biggs and Leung, and a course evaluation question-naire designed by the authors were used. Seventy-seven students answered the questionnaires and the questionnaires were analysed by Mann-Whitney U-test, and Fisher’s test was used as a pair comparison. One hundred forty comments made by the students were analysed using content analysis. The results showed that: 69% of the students regarded e-learning as a very good/good pedagogical method to study medical insurance. Men had a significantly higher rate of surface learning than women. A majority of the students thought that it was positive to take part of peer students’ assignments but they highlighted the risk of plagiarism and cheating. The students made use of the flexibility in this type of learning which suited their lifestyle.

    • Previous studies have shown that people hesitate to seek medical attention when experiencing the initial symptoms of acute myocardial infarction (AMI), but the reasons why and the events underpinning the decision-making process are unclear. The aim of this study was to describe the actions and experiences involved in the process of seeking medical attention in men with a first AMI.

  • Pre-Hospital Decision Process and Prognosis in Men and Women with Coronary Heart Disease
  • 2015
  • Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
    • The overall aim of this thesis was to describe experiences, strategies and actions in the prehospital phase among patients with a first acute myocardial infarction and to examine long-term trends in survival among patients with coronary heart disease. The thesis consists of two qualitative and two quantitative studies. Interviews were conducted with 21 men and 17 women, experiencing symptoms from a first acute myocardial infarction (AMI) and analyzed with Grounded Theory. Two national prospective cohort studies were performed by using the Swedish Inpatient register (IPR). From this, prognosis for 37,276 adult patients <55 years old with a first AMI and 94,328 patients aged >18 years who underwent a first coronary artery bypass (CABG) 1987-2006 could be estimated. During the decision process, various spectra of bodily changes were described in both men and women, sometimes over an extended period before submission to hospital. Intermittent, vague and insidious symptoms caused confusion about how to act. Vague symptoms sometimes experienced by the men did not match their preconception of typical symptoms in a myocardial infarction. To come to an understanding they compared with their past experiences which led to an awareness of the abnormality, the severity and the need for contact medical attention. The women usually attributed their symptoms to harmless conditions and struggled to continue with their responsibilities in their daily lives. Intensified symptoms made the women unable to perform their daily task and they could no longer maintain earlier explanations for their discomfort which contributed to an understanding for the need of professional help. Sometimes, when men and women sought medical attention for their discomfort, and had no objective signs of an AMI they were dismissed, with no diagnosis, which caused a hesitation to contact medical care once again. This emphasizes that health care professionals have to pay more attention to the patient’s narrative. In the quantitative part of the thesis younger men with a first AMI had a 2 to 4-fold risk for mortality compared to men in the same age in the general population while women had a 6 to 14-fold risk during the last study period (2002-2006). Survival increased during the study period in men. In women there was a favorable trend in survival until the last period 2002-2006 but survival then reverted to that in the second period (1992-1996) in the last period. Men and women ≥55 years surviving the first 30 days after CABG (coronary artery bypass grafting) showed a lower mortality risk than those in the general population and showed a decreasing trend in mortality during the study period. Women below the age of 55 showed no significant improvement in survival and had a 4-fold risk for mortality compared to women in the same age in the general population. Men <55 displayed improved survival, which was higher than that for men in the general population.

  • Risk for first onset depression in adults with congenital heart disease
  • 2022
  • Ingår i: INTERNATIONAL JOURNAL OF CARDIOLOGY CONGENITAL HEART DISEASE. - : Elsevier BV. - 2666-6685. ; 9
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: The long-term risk for depression among adults with congenital heart disease (ACHD) is unclear. Therefore, we assessed the risk for first onset of serious depression in patients with ACHD compared with a sex and age-matched control population without a congenital heart disease (CHD) diagnosis.Methods: We extracted all patients with CHD born from 1970 to 1999 who survived until age 18 years from the Swedish National Patient Register. For each case, 10 random controls without CHD were selected from the general population and matched by birth year and sex. Participants were followed-up until the first diagnosis of new onset serious depression requiring hospital or specialist outpatient care.Results: This study included 22,912 patients with ACHD and 224,259 controls. The mean age at depression onset was 30.1 years in the ACHD group and 30.3 years in controls. The overall associated risk for serious depression was higher among patients with ACHD compared with controls, with an adjusted hazard ratio (aHR) of 1.32 (95% confidence interval [CI]: 1.20-1.44). Patients in the complex lesion group had a 54% higher risk for depression (aHR 1.54, 95% CI: 1.10-2.18) compared with the control group. The corresponding result for the non-complex lesion group was aHR 1.30 (95% CI: 1.18-1.43).Conclusion: The long-term risk for serious depression was higher among young and middle-aged patients with ACHD compared with matched controls. The risk was particularly elevated among patients with complex lesions. Patients with ACHD need support through strategies to prevent depression.

    • To examine sex-specific trends in 4-year mortality among young patients with first acute myocardial infarction (AMI), 1987-2006. Results From the first to last 5-year period, the absolute excess risk decreased from 1.38 to 0.50 and 1.53 to 0.59 per 100 person-years among men aged 25–44 and 45–54years, respectively. Corresponding figures for women were a decrease from 2.26 to 1.17 and from 1.93 to 1.45 per 100 person-years, respectively. Trends for women were non-linear, decreasing to the same extent as those for men until the third period, then increasing. For the last 5-year period, the standardised mortality ratio for young survivors of AMI compared with the general population was 4.34 (95% CI 3.04 to 5.87) and 2.43 (95% CI 2.12 to 2.76) for men aged 25–44 and 45–54years, respectively, and 13.53 (95% CI 8.36 to 19.93) and 6.42 (95% CI 5.24 to 7.73) for women, respectively. Deaths not associated with cardiovascular causes increased from 21.5% to 44.6% in men and 41.5% to 65.9% in women. Conclusions Young male survivors of AMI have low absolute long-term mortality rates, but these rates remain twofold to fourfold that of the general population. After favourable development until 2001, women now have higher absolute mortality than men and a 6-fold to 14-fold risk of death compared with women in the general population.

  • Social Factors, Sex, and Mortality Risk After Coronary Artery Bypass Grafting: A Population-Based Cohort Study
  • 2019
  • Ingår i: Journal of the American Heart Association. - 2047-9980. ; 8:6
  • Tidskriftsartikel (refereegranskat)abstract
    • Background Little is known of the impact of social factors on mortality after coronary artery bypass grafting ( CABG ). We explored sex- and age-specific associations between mortality risk after CABG and marital status, income, and education. Methods and Results This population-based register study included 110742 CABG patients (21.3% women) from the SWEDEHEART registry (Swedish Web-system for Enhancement and Development of Evidence-based Care in Heart Disease Evaluated According to Recommended Therapies) operated 1992 to 2015. Cox regression models were used to study the relation between social factors and all-cause mortality. Never having been married compared with being married/cohabiting was associated with a higher risk in women than in men (hazard ratio 1.32, 95% CI 1.20-1.44) versus 1.17 (1.13-1.22), P=0.030 between sex. The lowest income quintile, compared with the highest, was associated with higher risk in men than in women (hazard ratio 1.44 [1.38-1.51] versus 1.25 [1.14-1.38], P=0.0036). Lowest education level was associated with higher risk without sex difference (hazard ratio 1.15 [1.11-1.19] versus 1.25 [1.16-1.35], P=0.75). For unmarried women aged 60 years at surgery with low income and low education, mortality 10years after surgery was 18%, compared with 11% in married women with high income and higher education level. The median life expectancy was 4.8years shorter. Corresponding figures for 60-year-old men were 21% versus 12% mortality risk at 10 years and 5.0years shorter life expectancy. Conclusions There are strong associations between social factors and mortality risk after CABG in both men and women. These results emphasize the importance of developing and implementing secondary prevention strategies for CABG patients with disadvantages in social factors.

  • Socioeconomic Factors, Secondary Prevention Medication, and Long-Term Survival After Coronary Artery Bypass Grafting: A Population-Based Cohort Study From the SWEDEHEART Registry.
  • 2020
  • Ingår i: Journal of the American Heart Association. - 2047-9980. ; 9:5
  • Tidskriftsartikel (refereegranskat)abstract
    • Background Low income and short education have been found to be independently associated with inferior survival after coronary artery bypass grafting (CABG), whereas the use of secondary prevention medications is associated with improved survival. We investigated whether underusage of secondary prevention medications contributes to the inferior long-term survival in CABG patients with a low income and short education. Methods and Results Patients who underwent CABG in Sweden between 2006 to 2015 and survived at least 6months after discharge (n=28448) were included in a population-based cohort study. Individual patient data from 5 national registries, including the SWEDEHEART (Swedish Web System for Enhancement and Development of Evidence-Based Care in Heart Disease Evaluated According to Recommended Therapies) registry, covering dispensing of secondary prevention medications (statins, platelet inhibitors, β-blockers, and RAAS inhibitors), socioeconomic factors, patient characteristics, comorbidity, and long-term mortaity were merged. All-cause mortality risk was estimated using multivariable Cox regression models adjusted for patient characteristics, baseline comorbidities, time-updated secondary prevention medications, and socioeconomic status. Long-term mortality was higher in patients with a low income and short education. Statins and platelet inhibitors were dispensed less often to patients with a low income, both at baseline and after 8years. The decline in dispensing over time was steeper for low-income patients. Short education was not associated with reduced dispensing of any secondary prevention medication. Use of statins (adjusted hazard ratio=0.57 [95% CI, 0.53-0.61]), RAAS inhibitors (adjusted hazard ratio=0.78 [0.73-0.84]), and platelet inhibitors (adjusted hazard ratio=0.74 [0.68-0.80]) were associated with reduced long-term mortality irrespective of socioeconomic status. Conclusions Secondary prevention medications are dispensed less often after CABG to patients with low income. Underusage of secondary prevention medications after CABG is associated with increased mortality risk independently of income and extent of education.

  • 2017
  • Ingår i: International Journal of Cardiology. - : Elsevier BV. - 0167-5273. ; 244, s. 316-321
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Updated knowledge about survival after coronary artery bypass graft (CABG) surgery is needed. We examined 20-year trends in 4-year survival after a first isolated CABG procedure, compared with that of the general population. Methods: We identified 94,328 patients surviving 30 days after a first isolated CABG 1987-2006 from the Swedish Inpatient Register. Results: Crude annual mortality rates remained stable at approximately 1% in patients aged 18-54 years and at approximately 2% in those aged >= 55 years. After adjustment for comorbidities, 4-year survival in men aged 18-54 and >= 55 years improved by 37% (HR: 0.63, 95% CI, 0.46-0.88) and 31% (HR: 0.69, 95% CI, 0.63-0.76), respectively, (1987-1991 vs. 2002-2006). The corresponding estimate for women aged >= 55 years was 38% (HR: 0.62, 95% CI, 0.52-0.75), with no significant change in survival in women aged b55 years (HR: 1.02, 95% CI, 0.52-2.03). Men and women aged b55 years had higher mortality than the general population, with standardized mortality ratios (SMR) of 1.76 (95% CI, 1.35-2.22) in men and 4.49 (95% CI, 2.74-6.68) in women during the last period (2002-2006). In contrast, patients aged >= 55 years had better survival with a SMR of 0.74 (95% CI, 0.70-0.78) in men and 0.82 (95% CI, 0.74-0.91) in women during 2002-2006. Conclusion: During 1987-2006, there was a significant improvement in survival after CABG for all categories, except in women aged < 55 years. Men and women aged >= 55 years who survived the first 30 days after CABG had a lower mortality risk than the general population.

    • To evaluate the association between statin use after surgical aortic valve replacement for aortic stenosis and long-term risk for major adverse cardiovascular events in a large population-based, nationwide cohort.All patients that underwent isolated surgical aortic valve replacement due to aortic stenosis in Sweden 2006-2020 and survived six months after discharge were included. Individual patient data from five nationwide registries were merged. Primary outcome is major adverse cardiovascular event (defined as all-cause mortality, myocardial infarction, or stroke). Multivariable Cox regression model adjusted for age, sex, comorbidities, valve type, operation year, and secondary prevention medications is used to evaluate the association between time-updated dispense of statins and long-term outcome in the entire study population, and in subgroups based on age, sex and comorbidities.A total of 11,894 patients were included. Statins were dispensed to 49.8% (5918/11894) of patients at baseline, and 51.0% (874/1713) after ten years. At baseline, 3.6% of patients were dispensed low dose, 69.4% medium dose and 27.0% high dose statins. After adjustments, ongoing statin treatment was associated with a reduced risk for major adverse cardiovascular event [adjusted hazard ratio 0.77 (95% confidence interval 0.71-0.83). p<0.001], mainly driven by a reduction in all-cause mortality [adjusted hazard ratio, 0.70 (0.64-0.76)], p<0.001. The results were consistent in all subgroups.The results suggest that statin therapy might be beneficial for patients undergoing surgical aortic valve replacement for aortic stenosis. Randomized controlled trials are warranted to establish causality between statin treatment and improved outcome.

    • The objective of this study was to evaluate the association of statin use after coronary artery bypass grafting (CABG) and long-term adverse events in a large population-based, nationwide cohort.All 35,193 patients who underwent first-time isolated CABG in Sweden from 2006 to 2017 and survived at least 6months after surgery were included. Individual patient data from the Swedish Web System for Enhancement and Development of Evidence-Based Care in Heart Disease Evaluated According to Recommended Therapies (SWEDEHEART) and 4 other nationwide registries were merged. Multivariable Cox regression models adjusted for age, sex, comorbidities, and time-updated treatment with other secondary preventive medications were used to evaluate the associations between statin treatment and outcomes. The primary end point was major adverse cardiovascular events (MACE). Median follow-up time to MACE was 5.3 (interquartile range, 2.5-8.2) years.Statins were dispensed to 95.7% of the patients six months after discharge and to 78.9% after 10years. At baseline, 1.4% of patients were prescribed low-, 57.6% intermediate-, and 36.7% high-dose statins. Ongoing statin treatment was associated with markedly reduced risk of MACE (adjusted hazard ratio [aHR], 0.56 [95% CI, 0.53-0.59]), all-cause mortality (aHR, 0.53 [95% CI, 0.50-0.56]), cardiovascular death (aHR, 0.54 [95% CI, 0.50-0.59]), myocardial infarction (aHR, 0.61 [95% CI, 0.55-0.69]), stroke (aHR, 0.66 [95% CI, 0.59-0.73]), new revascularization (aHR, 0.79 [95% CI, 0.70-0.88]), new angiography (aHR, 0.81 [95% CI, 0.74-0.88]), and dementia (aHR, 0.74 [95% CI, 0.65-0.85]; all P<.01), irrespective of the statin dose.Ongoing statin use was associated with a markedly reduced incidence of adverse events and mortality after CABG. Initiating and maintaining statin medication is essential in CABG patients.

    • There is no consensus on the choice of aortic valve prosthesis for patients with end-stage renal failure. We analyzed short- and long-term complications in dialysis patients who underwent aortic valve replacement (AVR) with either a biological (bAVR) or a mechanical (mAVR) prosthesis.All patients on dialysis who underwent bAVR or mAVR in Sweden from 1995 to 2017 (n=335) were included in a nationwide, population-based, observational, cohort study. Short and long-term complications were compared. Long-term mortality was compared with multivariable Cox regression analysis adjusted for age, sex, comorbidities, and a propensity score-matched model. Median follow-up was 2.8 (range, 0-16) years.Biological and mechanical valves were implanted in 253 (75.5%) and 82 (24.5%) patients, respectively. The bAVR patients were older and had more comorbidities. There was no significant difference in early complication rate. Thirty-day mortality was 9.1% in bAVR and 7.3% in mAVR patients (P=0.62). The multivariable Cox regression model did not show significant difference in mortality risk between bAVR and mAVR patients [adjusted hazard ratio (aHR) 1.33; 95% CI: 0.84-2.13; P=0.22]. The results were confirmed in the propensity-score matched model. The rate of aortic valve reoperations did not differ significantly between the bAVR and mAVR group.The short- and long-term complication rate is high, and the expected life expectancy limited, in dialysis patients undergoing AVR, without significant difference between biological and mechanical prostheses. The results suggest that biological valve prosthesis, avoiding systemic anticoagulation, is appropriate in most dialysis patients.

    • Tricuspid annuloplasty is associated with increased risk of atrioventricular block and subsequent implantation of a permanent pacemaker. However, the exact incidence of permanent pacemaker, associated risk factors, and outcomes in this frame remain debated. The aim of the study was to report permanent pacemaker incidence, risk factors, and outcomes after tricuspid annuloplasty from nationwide databases.By using data from multiple Swedish mandatory national registries, all patients (n=1502) who underwent tricuspid annuloplasty in Sweden from 2006 to 2020 were identified. Patients who needed permanent pacemaker within 30days from surgery were compared with those who did not. The cumulative incidence of permanent pacemaker implantation was estimated. A multivariable logistic regression model was fit to identify risk factors of 30-day permanent pacemaker implantation. The association between permanent pacemaker implantation and long-term survival was evaluated with multivariable Cox regression.The 30-day permanent pacemaker rate was 14.2% (214/1502). Patients with permanent pacemakers were older (69.8±10.3years vs 67.5±12.4years, P=.012). Independent risk factors of permanent pacemaker implantation were concomitant mitral valve surgery (odds ratio, 2.07; 95% CI, 1.34-3.27), ablation surgery (odds ratio, 1.59; 95% CI, 1.12-2.23), and surgery performed in a low-volume center (odds ratio, 1.85; 95% CI, 1.17-2.83). Permanent pacemaker implantation was not associated with increased long-term mortality risk (adjusted hazard ratio, 0.74; 95% CI, 0.53-1.03).This nationwide study demonstrated a high risk of permanent pacemaker implantation within 30days of tricuspid annuloplasty. However, patients who needed a permanent pacemaker did not have worse long-term survival, and the cumulative incidence of heart failure and major adverse cardiovascular events was similar to patients who did not receive a permanent pacemaker.

    • Data on prognostic implications of new-onset postoperative atrial fibrillation (POAF) after surgical aortic valve replacement (SAVR) is limited. We sought to explore associations between POAF, early-initiated oral anticoagulation (OAC), and long-term outcome after SAVR and combined SAVR+CABG.This is a retrospective, population-based study including all isolated SAVR (n=7038) and combined SAVR and CABG patients (n=3854) without a history of preoperative atrial fibrillation in Sweden 2007-2017. Individual patient data was merged from four nationwide registries. Inverse Probability of Treatment Weighting (IPTW) adjusted Cox regression models were employed separately in SAVR and SAVR+CABG patients. Median follow-up time was 4.7years (range 0-10years).POAF occurred in 44.5% and 50.7% of SAVR and SAVR+CABG patients, respectively. In SAVR patients, POAF was associated with increased long-term risk of death [adjusted hazard ratio (aHR) 1.21 (95% confidence interval 1.06-1.37)], ischaemic stroke [aHR 1.32 (1.08-1.59)], any thromboembolism, heart failure hospitalization, and recurrent atrial fibrillation. In SAVR+CABG, POAF was associated with death [aHR 1.31 (1.14-1.51)], recurrent atrial fibrillation, and heart failure, but not with ischaemic stroke [aHR 1.04 (0.84-1.29)] or thromboembolism. OAC was dispensed within 30days after discharge to 67.0% and 65.9% respectively of SAVR and SAVR+CABG patients with POAF. Early initiated OAC was not associated with reduced risk of death, ischaemic stroke or thromboembolism in any group of patients.POAF after SAVR is associated with an increased risk of long-term mortality and morbidity. Further studies are warranted to clarify the role of OAC in SAVR patients with POAF.

    • New-onset postoperative atrial fibrillation (POAF) after cardiac surgery is associated with worse short- and long-term outcome. Although the clinical presentation of POAF varies substantially, almost all studies model it with a dichotomous yes/no variable. We explored potential associations between the clinical course of POAF and long-term outcome.This retrospective observational single-center study included 6435 CABG and/or valve patients between 2010 and 2018. POAF patients were grouped into 1) spontaneous/pharmacological conversion to sinus rhythm, 2) sinus rhythm after electrical cardioversion, and 3) sustained atrial fibrillation (AF) at discharge. Multivariable Cox regression models adjusted for age, sex, type of surgery, co-morbidities, and early-initiated oral anticoagulation were used to study associations between the clinical course of POAF and long-term risk for mortality, ischemic stroke, thromboembolic events, heart failure hospitalization, and major bleeding. Median follow-up time was 3.8 years (range: 0-8.3 years).POAF occurred in 2172 (33.8%) of the patients, 94.9% of whom converted to sinus rhythm before discharge. Of these, 73.6% converted spontaneously or with pharmacological treatment, and 26.4% after electrical cardioversion. Both sustained AF and electrical cardioversion were independently associated with an increased long-term risk for heart failure (adjusted hazard ratio for sustained AF at discharge: 2.55, 95%CI: 1.65-3.93, p<0.001; for electrical cardioversion: 1.28, 95%CI: 1.00-1.65, p=0.047), but not with increased long-term risk for death, thromboembolic complications, or bleedings.A more complicated POAF course is associated with increased long-term risk for heart failure hospitalization, but not for all-cause mortality or thromboembolic complications.

    • Aims To provide data guiding long-term antithrombotic therapy after coronar y arter y by-pass grafting (CABG) in patients with preoperative atrial fibrillation (AF). Methods and results From the SWEDEHEART registry, we included all patients, between January 2006 and September 2016, with preoperative AF and CHA2DS2-VASC score >2, undergoing CABG. Based on dispensed prescriptions 12 to 18 months after CABG, patients were divided in 3 groups: use of platelet inhibitors (PI) only, oral anticoagulant (OAC) only or a combination of OAC + PI. Outcomes were: Major adverse cardiac and cerebrovascular events (MACCE, [all-cause death, myocardial infarction, or stroke]), net adverse clinical events (NACE, [MACCE or bleeding]) and the individual components of NACE. Inverse probability of treatment weighting was used to adjust for the non-randomized study design. Among 2,564 patients, 1,040 (41%) were treated with PI alone, 1,064 (41%) with OAC alone, and 460 (18%) with PI + OAC. Treatment with PI alone was associated with higher risk for MACCE (adjusted HR 1.43, 95% CI 1.09-1.88), driven by higher risk for stroke and MI, compared with OAC alone. Treatment with PI + OAC, was associated with higher risk for NACE (adjusted HR 1.40, 95% CI 1.06-1.85), driven by higher risk for bleeds, compared with OAC alone. Conclusion In this real-world observational study, a high proportion of patients with AF, undergoing CABG, did not receive a long-term OAC therapy. Treatment with OAC alone was associated with a net clinical benefit, compared with PI alone or PI + OAC. (Am Heart J 2023;257:69-77.)

    • Cardiopulmonary bypass management may potentially play a role in the development of new-onset atrial fibrillation after cardiac surgery. The aim of this study was to explore this potential association.Patients who underwent coronary artery bypass grafting and/or valvular surgery during 2016-2020 were included in an observational single-centre study. Data collected from the SWEDEHEART Registry, and a local Cardiopulmonary bypass database were merged. Associations between individual cardiopulmonary bypass variables (Cardiopulmonary bypass and aortic clamp times, arterial and central venous pressure, mixed venous oxygen saturation, blood flow index, bladder temperature, and haematocrit) and new-onset atrial fibrillation were analysed using multivariable logistic regression models adjusted for patient characteristics, comorbidities, and surgical procedure.Out of 1,999 patients, 758 (37.9%) developed new-onset atrial fibrillation. Patients with new-onset postoperative atrial fibrillation were older, had a higher incidence of previous stroke, worse renal function and higher EuroSCORE II and CHA2DS2-VASc scores, and more often underwent valve surgery. Longer cardiopulmonary bypass time (adjusted odds ratio (aOR) 1.05 per 10min (95% confidence interval (CI) 1.01-1.08); p=0.008) and higher flow index (aOR 1.21 per 0.2L/m2 (95% CI 1.02-1.42); p=0.026) were associated with an increased risk for new-onset atrial fibrillation, while the other variables were not. A sensitivity analysis only including patients with isolated coronary artery bypass grafting supported the primary analyses.Cardiopulmonary bypass management following current guideline recommendations appears to have minor or no influence on the risk of developing new-onset atrial fibrillation after cardiac surgery.

    • Background The long-term impact of new-onset postoperative atrial fibrillation (POAF) after coronary artery bypass grafting and the benefit of early-initiated oral anticoagulation (OAC) in patients with POAF are uncertain. Methods and Results All patients who underwent coronary artery bypass grafting without preoperative atrial fibrillation in Sweden from 2007 to 2015 were included in a population-based study using data from 4 national registries: SWEDEHEART (Swedish Web System for Enhancement and Development of Evidence-based Care in Heart Disease Evaluated According to Recommended Therapies), National Patient Registry, Dispensed Drug Registry, and Cause of Death Registry. POAF was defined as any new-onset atrial fibrillation during the first 30 postoperative days. Cox regression models (adjusted for age, sex, comorbidity, and medication) were used to assess long-term outcome in patients with and without POAF, and potential associations between early-initiated OAC and outcome. In a cohort of 24523 patients with coronary artery bypass grafting, POAF occurred in 7368 patients (30.0%), and 1770 (24.0%) of them were prescribed OAC within 30days after surgery. During follow-up (median 4.5years, range 0‒9years), POAF was associated with increased risk of ischemic stroke (adjusted hazard ratio [aHR] 1.18 [95% CI, 1.05‒1.32]), any thromboembolism (ischemic stroke, transient ischemic attack, or peripheral arterial embolism) (aHR 1.16, 1.05‒1.28), heart failure hospitalization (aHR 1.35, 1.21‒1.51), and recurrent atrial fibrillation (aHR 4.16, 3.76‒4.60), but not with all-cause mortality (aHR 1.08, 0.98‒1.18). Early initiation of OAC was not associated with reduced risk of ischemic stroke or any thromboembolism but with increased risk for major bleeding (aHR 1.40, 1.08‒1.82). Conclusions POAF after coronary artery bypass grafting is associated with negative prognostic impact. The role of early OAC therapy remains unclear. Studies aiming at reducing the occurrence of POAF and its consequences are warranted.

  • Stroke Risk Stratification in Patients With Postoperative Atrial Fibrillation After Coronary Artery Bypass Grafting.
  • 2022
  • Ingår i: Journal of the American Heart Association. - 2047-9980. ; 11:10
  • Tidskriftsartikel (refereegranskat)abstract
    • Background The CHA2DS2-VASc (congestive heart failure, hypertension, age ≥75years, diabetes, previous stroke or TIA [transient ischemic attack], vascular disease, age 65 to 74years, sex category female; 2 indicates 2 points, otherwise 1 point) scoring system is recommended to guide decisions on oral anticoagulation therapy for stroke prevention in patients with nonsurgery atrial fibrillation. A score ≥1 in men and ≥2 in women, corresponding to an annual stroke risk exceeding 1%, warrants long-term oral anticoagulation provided the bleeding risk is acceptable. However, in patients with new-onset postoperative atrial fibrillation, the optimal risk stratification method is unknown. The aim of this study was therefore to evaluate the CHA2DS2-VASc scoring system for estimating the 1-year ischemic stroke risk in patients with new-onset postoperative atrial fibrillation after coronary artery bypass grafting. Methods and Results All patients with new-onset postoperative atrial fibrillation and without oral anticoagulation after first-time isolated coronary artery bypass grafting performed in Sweden during 2007 to 2017 were eligible for this registry-based observational cohort study. The 1-year ischemic stroke rate at each step of the CHA2DS2-VASc score was estimated using a Kaplan-Meier estimator. Of the 6368 patients included (mean age, 69.9years; 81% men), >97% were treated with antiplatelet drugs. There were 147 ischemic strokes during the first year of follow-up. The ischemic stroke rate at 1year was 0.3%, 0.7%, and 1.5% in patients with CHA2DS2-VASc scores of 1, 2, and 3, respectively, and ≥2.3% in patients with a score ≥4. A sensitivity analysis, with the inclusion of patients on anticoagulants, was performed and supported the primary results. Conclusions Patients with new-onset atrial fibrillation after coronary artery bypass grafting and a CHA2DS2-VASc score <3 have such a low 1-year risk for ischemic stroke that oral anticoagulation therapy should probably be avoided.

    • Our goal was to compare short- and midterm outcomes after coronary artery bypass grafting (CABG) using 2 different revascularization strategies.A total of 6895 patients were included who had CABG in Sweden from 2009 to 2015 using the left internal mammary artery to the left anterior descending artery and either a single sequential saphenous vein graft connecting the left and right coronary territories to the aorta (snake graft, n=2122) or separate vein grafts to both territories (n=4773). Data were obtained from the Swedish Web System for Enhancement of Evidence-Based Care in Heart Disease Evaluated According to Recommended Therapies (SWEDEHEART) and the Swedish Patient Registry. The groups were compared using adjusted logistic regression for short-term (30-day) and Cox regression and flexible parametric survival models for midterm outcomes. Primary outcome was a composite of all-cause mortality, myocardial infarction (MI), reangiography and new revascularization. The median follow-up time was 35months.At 30days, the incidences of the composite end point [odds ratio (OR) 1.31, 95% confidence interval (CI) 1.03-1.68; P=0.03] and reangiography (OR 1.51, 95% CI 1.07-2.14; P=0.02) were higher in the snake group. There was also a trend towards higher mortality (OR 1.47, 95% CI 0.97-2.22; P=0.07). The event rates during the complete follow-up period were 6.5 (5.9-7.2) and 5.7 (5.3-6.1) per 100 person-years for the snake group and the separate vein group, respectively. At the midterm follow-up, no significant difference between the groups could be shown for the composite end point [hazard ratio (HR) 1.08, 95% CI 0.95-1.22; P=0.24], mortality (HR 0.95, 95% CI 0.79-1.14; P=0.56), MI (HR 1.11, 95% CI 0.88-1.41; P=0.39) or new revascularization (HR 1.19, 95% CI 0.94-1.50; P=0.15), whereas reangiography remained more common in the snake group (HR 1.25, 95% CI 1.05-1.48; P=0.01).Snake grafts were associated with a higher rate of early postoperative complications, possibly reflecting a more demanding surgical technique, whereas midterm outcomes were comparable. Based on these data, one strategy cannot be recommended over the other.
