- The Swedish Web-system for Enhancement and Development of Evidence-based care in Heart disease Evaluated According to Recommended Therapies (SWEDEHEART) supports continuous monitoring and improvement of care for coronary artery disease, catheter-based and surgical coronary interventions, secondary prevention as well as catheter based and surgical valve intervention, by providing extensive data on base-line, diagnostic, procedural and outcome variables. Design. This national quality registry collects information from all Swedish hospitals treating patients with acute coronary artery disease and all patients undergoing coronary angiography, catheter-based interventions or heart surgery. Combination with other national mandatory official registries enables complete follow-up of all individuals regarding myocardial infarction, new interventional procedures, death and all-cause hospitalizations. The registry is governed by an independent steering committee and funded by the Swedish National Health care provider. The software is developed by Uppsala Clinical Research Center. Results. The SWEDEHEART Quality Index reflects overall quality of care for coronary artery disease including secondary prevention. In comparison with 2011, an improvement of the index occurred in 2012 overall. There was however, still a wide range in performance between individual centers, emphasizing the need for continuous monitoring of quality of care at a national as well as on a center level. © 2014 Informa Healthcare.

Tidskriftsartikel (refereegranskat)abstract
- Background: CVD-patients with higher levels of cardiac anxiety suffer psychologically, as well as being at increased risk for cardiac morbidity and mortality. Therefore it is important to be able to assess CA in a clinical setting. It is currently measured with the Cardiac Anxiety Questionnaire, which has conflicting findings regarding its factor structure, and it has not been validated in a Swedish population. This study aimed to examine the factor structure of CAQ and its psychometric properties in a Swedish CVD-population.Methods: Nine hundred thirty patients post-MI were recruited at different Swedish hospitals and completed the CAQ, along with several other questionnaires. Exploratory factor analysis and confirmatory factor analysis were conducted to explore factor structure and to inspect various factor solutions from previous research. Standard psychometric tests were performed for the CAQ to test its validity and reliability.Results: The exploratory analysis found a model with the factors Fear/Worry, Avoidance and Attention. The confirmatory factor analysis indicated that a 3-factor solution best fitted the data, but with certain items removed. Additionally, psychometric properties turned out acceptable in a Swedish post-MI population.Conclusions: We conclude that the original 3-factor structure of the CAQ is valid, but that the questionnaire could be revised in regard to some items. A shorter 10-items version could also be considered. We also confirm that the CAQ is a valid instrument to measure CA in a Swedish MI-population.

Tidskriftsartikel (refereegranskat)abstract
- Background and aim: In the aftermath of a myocardial infarction with non-obstructive coronary arteries (MINOCA) or Takotsubo syndrome (TS), patients commonly express high levels of stress and anxiety. Current treatment alternatives rarely address these issues. The planned E-health Treatment of Stress and Anxiety in Stockholm Myocardial Infarction With Non-obstructive Coronaries Study (e-SMINC) aims to evaluate the effects of an internet-based intervention, building on cognitive behavioral therapy (CBT) by comparison with treatment as usual using an RCT approach. This was a small-scale single arm study designed to test the feasibility of the RCT, addressing uncertainties regarding recruitment, data collection, and intervention delivery.Methods: Participant recruitment and screening took place before discharge from the coronary care unit at a large Swedish hospital. Eligible patients were invited to a nine-step psychologist guided, internet-based CBT intervention. The sample size was set in advance to 10 participants completing the intervention. The recruitment and flow of participants were documented and evaluated in relation to seven pre-defined progression criteria. Self-reports of anxiety (HADS-A), stress (PSS-14), cardiac anxiety (CAQ), posttraumatic stress (IES-6) and quality of life (Rand-36), collected at screening, pre-intervention and post-intervention, were analysed descriptively and by effect sizes (Cohen's d). Individual interviews targeting participant experiences were conducted.Results: Six out of seven progression criteria yielded no concerns. Out of 49 patients with a working diagnosis of MINOCA or TS, 31 were eligible for screening, 26 consented to participate, and 14 were eligible with regard to symptoms of stress and/or anxiety. Eleven completed the pre-assessment and were given access the intervention, and 9 completed the intervention. Only the number of patients screened prior to eligibility assessment was slightly lower than expected, indicating possible concerns. Self-reports of anxiety, stress, cardiac anxiety, posttraumatic stress, and quality of life all indicated symptom reduction from pre- to post-intervention, generally showing large effect sizes (d = 0.6–2.6). The general consensus among participants was that the programme was helpful and relevant, and that the personal contact with the psychologist was highly valued. Setting aside time to complete assignments was found critical.Conclusion: Conducting a full scale RCT was found feasible. Inclusion of more study sites and minor amendments to the protocol and intervention were decided to improve feasibility further.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: The Heart School is a standard component of cardiac rehabilitation after myocardial infarction in Sweden. The group-based educational intervention aims to improve modifiable risks, in turn reducing subsequent morbidity and mortality. However, an evaluation with respect to mortality is lacking.AIMS: Using linked population registries, we estimated the association of attending Heart School with both all-cause and cardiovascular mortality, two and five years after admission for first-time myocardial infarction.METHODS: Patients with first-time myocardial infarction (<75 years) were identified as consecutively registered in the nationwide heart registry, SWEDEHEART (2006-2015), with >99% complete follow-up in the Causes of Death registry for outcome events. Of 192,059 myocardial infarction admissions, 47,907 unique patients with first-time myocardial infarction surviving to the first cardiac rehabilitation visit constituted the study population. The exposure was attending Heart School at the first cardiac rehabilitation visit 6-10 weeks post-myocardial infarction. Data on socioeconomic status was acquired from Statistics Sweden. After multiple imputation, propensity score matching was performed. The association of exposure with mortality was estimated with Cox regression and survival curves.RESULTS: After matching, attending Heart School was associated (hazard ratio (95% confidence interval)) with a markedly lower risk of both all-cause (two-year hazard ratio = 0.53 (0.44-0.64); five-year hazard ratio = 0.62 (0.55-0.69)) and cardiovascular (0.50 (0.38-0.65); 0.57 (0.47-0.69)) mortality. The results were robust in several sensitivity analyses.CONCLUSIONS: Attending Heart School during cardiac rehabilitation is associated with almost halved all-cause and cardiovascular mortality after first-time myocardial infarction. The result warrants further investigation through adequately powered randomised trials.

- Objectives. The Swedish Web-system for Enhancement and Development of Evidence-based care in Heart disease Evaluated According to Recommended Therapies (SWEDEHEART) collects data to support the improvement of care for heart disease. Design. SWEDEHEART collects on-line data from consecutive patients treated at any coronary care unit n = (74), followed for secondary prevention, undergoing any coronary angiography, percutaneous coronary intervention, percutaneous valve or cardiac surgery. The registry is governed by an independent steering committee, the software is developed by Uppsala Clinical Research Center and it is funded by The Swedish national health care provider independent of industry support. Approximately 80,000 patients per year enter the database which consists of more than 3 million patients. Results. Base-line, procedural, complications and discharge data consists of several hundred variables. The data quality is secured by monitoring. Outcomes are validated by linkage to other registries such as the National Cause of Death Register, the National Patient Registry, and the National Registry of Drug prescriptions. Thanks to the unique social security number provided to all citizens follow-up is complete. The 2011 outcomes with special emphasis on patients more than 80 years of age are presented. Conclusion. SWEDEHEART is a unique complete national registry for heart disease.

Tidskriftsartikel (refereegranskat)abstract
- Background: General cognitive ability (CA) is positively associated with later physical and mental health, health literacy, and longevity. We investigated whether CA estimated approximately 30 years earlier in young adulthood predicted lifestyle-related risk factors and two-year survival in first myocardial infarction (MI) male patients.Methods: Young adulthood CA estimated through psychometric testing at age 18–20 years was obtained from the mandatory military conscript registry (INSARK) and linked to national quality registry SWEDEHEART/RIKS-HIA data on smoking, diabetes, hypertension, obesity (BMI > 30 kg/m2) in 60 years or younger Swedish males with first MI. Patients were followed up in the Cause of Death registry. The 5659 complete cases (deceased = 106, still alive = 5553) were descriptively compared. Crude and adjusted associations were modelled with logistic regression.Results: After multivariable adjustment, one SD increase in CA was associated with a decreased odds ratio of being a current smoker (0.63 [0.59, 0.67], P < 0.001), previous smoker (0.79 [0.73, 0.84], P < 0.001), having diabetes (0.82 [0.74, 0.90], P < 0.001), being obese (0.90 [0.84, 0.95], P < 0.001) at hospital admission, and an increased odds ratio of two-year survival (1.26 [1.02, 1.54], P < 0.001). CA was not associated with hypertension at hospital admission (1.03 [0.97, 1.10], P = 0.283).Conclusions: This study found substantial inverse associations between young adulthood CA, and middle-age lifestyle risk factors smoking, diabetes, and obesity, and two-year survival in first MI male patients. CA assessment might benefit risk stratification and possibly aid further tailoring of secondary preventive strategy.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: While patient performance after participating in cardiac rehabilitation programmes after acute myocardial infarction is regularly reported through registry and survey data, information on cardiac rehabilitation programme characteristics is less well described.AIM: The aim of this study was to evaluate Swedish cardiac rehabilitation programme characteristics and adherence to European Guidelines on Cardiovascular Disease Prevention.METHOD: Cardiac rehabilitation programme characteristics at all 78 cardiac rehabilitation centres in Sweden in 2016 were surveyed using a web-based questionnaire (100% response rate). The questions were based on core components of cardiac rehabilitation as recommended by European Guidelines.RESULTS: There was a wide variation in programme duration (2-14 months). All programmes reported offering an individual post-discharge visit with a nurse, and 90% (n = 70) did so within three weeks from discharge. Most programmes offered centre-based exercise training (n = 76, 97%) and group educational sessions (n = 61, 78%). All programmes reported to the national audit, SWEDEHEART, and 60% (n = 47) reported that performance was regularly assessed using audit data, to improve quality of care. Ninety-six per cent (n = 75) had a core team consisting of a cardiologist, a physiotherapist and a nurse and 76% (n = 59) reported having a medical director. Having other allied healthcare professionals included in the cardiac rehabilitation team varied. Forty per cent (n = 31) reported having regular team meetings where nurses, physiotherapists and cardiologist could discuss patient cases.CONCLUSION: The overall quality of cardiac rehabilitation programmes provided in Sweden is high. Still, there are several areas of potential improvement. Monitoring programme characteristics as well as patient outcomes might improve programme quality and patient outcomes both at a local and a national level.

Dose–Response Relationship of Total and Leisure Time Physical Activity to Risk of Heart Failure : a prospective cohort study
- 2014
-
Ingår i: Circulation Heart Failure. - 1941-3289 .- 1941-3297. ; 7:5, s. 701-708
-
Tidskriftsartikel (refereegranskat)abstract
- Background—The nature of the association between levels of physical activity and risk of heart failure is little known. We investigated nonlinear associations of total and leisure time physical activity with risk of heart failure.Methods and Results—In 1997, 39 805 persons without heart failure completed a questionnaire of lifestyle factors and medical history. We used Cox regression models to investigate total (adjusting for education and previous myocardial infarction) and direct (multivariable-adjusted) effects of self-reported total and leisure time physical activity on risk of heart failure of any cause and heart failure of nonischemic origin. Heart failure diagnoses were obtained until December 31, 2010. Higher leisure time physical activity was associated with lower risk of heart failure of any cause; hazard ratio of the total effect of leisure time physical activity was for fifth versus first quintile 0.54; 95% confidence interval was 0.44 to 0.66. The direct effect was similar. High total daily physical activity level was associated with lower risk of heart failure, although the effect was less pronounced than for leisure time physical activity (total effect hazard ratio, 0.81; 95% confidence interval, 0.69–0.95; fifth versus first quintile). A similar direct effect observed.Conclusions—Leisure time physical activity was inversely related to risk of developing heart failure in a dose–response fashion. This was reflected in a similar but less pronounced association of total physical activity with risk of heart failure. Only part of the effects appeared to be mediated by traditional risk factors.

Exercise capacity and muscle strength and risk of vascular disease and arrhythmias : A cohort study of 1.26 million young men
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Background:While physical activity and exercise protects against cardiovascular disease, athletes have higher risk of atrial fibrillation and other arrhythmias. Graded independent and joint influences of exercise capacity and muscle strength on these diseases are unknown.Methods:All 1.26 million Swedish men who participated in mandatory military conscription between 1972 and 1995 (at a median age of 18.2 years) contributed. Multivariable-adjusted Cox proportional hazards models were used to evaluate the associations of maximal exercise capacity and muscle strength at conscription to subsequent risk of vascular disease and arrhythmias, as identified in national registries.Results:During a median follow-up of 26.3 years, about 26,000 hospitalizations for vascular disease events and 17,000 for arrhythmias occurred. Exercise capacity was inversely associated with risk of vascular disease (hazard ratio [HR] 0.64; 95% confidence interval [CI] 0.61-0.67]; for 5th vs. 1st quintile) and so was muscle strength (HR 0.79; 0.76-0.83; for 5th vs. 1st quintile ). Similar associations were seen across a range of major vascular disease events. Exercise capacity was associated with incidence of arrhythmias in a U-shaped fashion (HR 0.91; 0.86-0.96; for 3rd vs. 1st quintile, and 0.99; 0.94-1.04; for 5th vs. 1st quintile). Higher muscle strength was associated with lower risk of arrhythmias (HR 0.87; 0.83-0.91; for 5th vs. 1st quintile). Conclusion:Exercise capacity and muscle strength in late adolescence are independently and jointly associated with long-term risk of vascular disease and arrhythmias. The lower risk of vascular events with higher exercise capacity was not outweighed by higher risk of arrhythmias.

Physical Activity and Cardiovascular Disease

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The aim was to investigate associations of fitness and types and levels of physical activity with subsequent risk of cardiovascular disease.Four large-scale longitudinal cohort studies were used. The exposures were different measures related to physical activity and the outcomes were obtained through linkage to the Swedish In-Patient Register. In a cohort of 466 elderly men without pre-existing cardiovascular disease, we found that skeletal muscle morphology was associated with risk of cardiovascular events. A high amount of type I (slow-twitch, oxidative) skeletal muscle fibres was associated with lower risk of cardiovascular events and high amount of type IIx was associated with higher risk of cardiovascular events. This association was only seen among physically active men. Among 39,805 participants in a fundraising event, higher levels of both total and leisure time physical activity were associated with lower risk of heart failure. The associations were strongest for leisure time physical activity. In a cohort of 53,755 participants in the 90 km skiing event Vasaloppet, a higher number of completed races was associated with higher risk of atrial fibrillation and a higher risk of bradyarrhythmias. Further, better relative performance was associated with a higher risk of bradyarrhythmias. Among 1,26 million Swedish 18-year-old men, exercise capacity and muscle strength were independently associated with lower risk of vascular disease. The associations were seen across a range of major vascular disease events (ischemic heart disease, heart failure, stroke and cardiovascular death). Further, high exercise capacity was associated with higher risk of atrial fibrillation and a U-shaped association with bradyarrhythmias was found. Higher muscle strength was associated with lower risk of bradyarrhythmias and lower risk of ventricular arrhythmias.These findings suggest a higher rate of atrial fibrillation with higher levels of physical activity. The higher risk of atrial fibrillation does not appear to lead to a higher risk of stroke. In contrast, we found a strong inverse association of higher exercise capacity and muscle strength with vascular disease. Further, high exercise capacity and muscle strength are related to lower risk of cardiovascular death, including arrhythmia deaths. From a population perspective, the total impact of physical activity on cardiovascular disease is positive.
