- IntroductionDual antiplatelet therapy (DAPT), including potent P2Y12 inhibition after ST-elevation myocardial infarction (STEMI) is recommended in clinical guidelines. However, bleeding complications are common, and associated with worse outcomes. The aim of this study was to assess incidence of bleeding events with a clopidogrel-based compared to a ticagrelor-based DAPT strategy, in a real world population. Secondary aims were to assess ischemic complications and mortality.Methods and ResultsWe identified 330 consecutive STEMI patients with a clopidogrel-based and 330 with a ticagrelor-based DAPT strategy. Patientś medical records were searched for bleeding and ischemic complications, over 6 months follow-up.The two groups were well balanced in baseline characteristics, age (69 years inboth groups), sex (31% vs 32% females), history of diabetes (19% vs 21%), hypertension (43% in both) and MI (17% vs 15%). There was no difference in CRUSADE bleeding score (28 vs 29). After discharge, there were more than twice as many bleeding events with a ticagrelor-based compared with a clopidogrel-based strategy (13.3% vs. 6.5%, p = 0.005). Bleeding events included significantly more severe bleeding complications (TIMI major/minor [5.8 vs 1.0, p = 0.001]) during the ticagrelor-based period. There was no significant difference in the composite of death, MI or stroke (7.8% vs 7.1%, p = 0.76).ConclusionsIn this observational study, a ticagrelor-based DAPT strategy was associated with significantly more bleeding complications, without any significant change in death, MI or stroke. Larger studies are needed to determine whether bleeding complications off-sets benefits with a more potent DAPT strategy in older and more comorbid real-life patients.

Tidskriftsartikel (refereegranskat)abstract
- Background: The recently published COMPLETE trial has demonstrated that patients with ST-segment elevation myocardial infarction (STEMI) and multivessel coronary artery disease (MVD), who underwent successful percutaneous coronary intervention (PCI) of both culprit and non-culprit (vs. culprit-only) lesions had a reduced risk of major adverse cardiac events (MACE), but not of cardiovascular or total mortality. The aim of this meta-analysis was to assess the efficacy of complete revascularization on cardiovascular or total mortality reduction using available randomized controlled trials (RCTs) including the COMPLETE trial, in hemodynamically stable STEMI patients with MVD. Methods: PubMed, MEDLINE, Embase, Scopus, Google Scholar, CENTRAL and ClinicalTrials.gov databases search identified 10 RCTs of 7033 patients with STEMI and MVD which compared complete (n = 3420) vs. only culprit lesion (n = 3613) PCI for a median 27.7 months follow-up. Random effect risk ratios were used to estimate for efficacy and safety outcomes. Results: Complete revascularization reduced the risk of MACE (10.4% vs.16.6%; RR = 0.59, 95% CI: 0.47 to 0.74, p < 0.0001), CV mortality (2.87% vs. 3.72%; RR = 0.73, 95% CI: 0.56 to 0.95, p = 0.02), reinfarction (5.1% vs. 7.1%; RR = 0.67, 95% CI: 0.52 to 0.86, p = 0.002), urgent revascularization (7.92% vs.17.4%; RR = 0.47, 95% CI: 0.30 to 0.73, p < 0.001), and CV hospitalization (8.68% vs.11.4%; RR = 0.65, 95% CI: 0.44to 0.96, p = 0.03) compared with culprit only revascularization. All-cause mortality, stroke, major bleeding events, or contrast induced nephropathy were not affected by the revascularization strategy. Conclusion: The findings of this meta-analysis suggest that in patients with STEMI and MVD, complete revascularization is superior to culprit-only PCI in reducing the risk of MACE outcomes, including cardiovascular mortality, without increasing the risk of adverse safety outcomes.

Tidskriftsartikel (refereegranskat)abstract
- Background: Physical activity improves health, exercise tolerance and quality of life in adults with congenital heart disease (CHD), and exercise training is in most patients a high-benefit low risk intervention. However, factors that influence the confidence to perform exercise training, i.e. exercise self-efficacy (ESE), in CHD patients are virtually unknown. We aimed to identify factors related to low ESE in adults with CHD, and potential strategies for being physically active.Methods: Seventy-nine adults with CHD; 38 with simple lesions (16 women) and 41 with complex lesions (17 women) with mean age 36.7 ± 14.6 years and 42 matched controls were recruited. All participants completed questionnaires on ESE and quality of life, carried an activity monitor (Actiheart) during four consecutive days and performed muscle endurance tests.Results: ESE in patients was categorised into low, based on the lowest quartile within controls, (≤ 29 points, n = 34) and high (> 29 points, n = 45). Patients with low ESE were older (42.9 ± 15.1 vs. 32.0 ± 12.4 years, p = 0.001), had more complex lesions (65% vs. 42%, p = 0.05) more often had New York Heart Association functional class III (24% vs. 4%, p = 0.01) and performed fewer shoulder flexions (32.5 ± 15.5 vs. 47.7 ± 25.0, p = 0.001) compared with those with high ESE. In a logistic multivariate model age (OR; 1.06, 95% CI 1.02-1.10), and number of shoulder flexions (OR; 0.96, 95% CI 0.93-0.99) were associated with ESE.Conclusion: In this study we show that many adults with CHD have low ESE. Age is an important predictor of low ESE and should, therefore, be considered in counselling patients with CHD. In addition, muscle endurance training may improve ESE, and thus enhance the potential for being physically active in this population.

Echocardiography in inflammatory heart disease: A comparison of giant cell myocarditis, cardiac sarcoidosis, and acute non-fulminant myocarditis
- 2023

Ingår i: IJC Heart and Vasculature. - 2352-9067. ; 46

Tidskriftsartikel (refereegranskat)abstract
- Background: Giant cell myocarditis (GCM) and cardiac sarcoidosis (CS) are, in contrast to acute non-fulminant myocarditis (ANFM), rare inflammatory diseases of the myocardium with poor prognosis. Although echocardiography is the first-line diagnostic tool in these patients, their echocardiographic appearance has so far not been systematically studied. Methods: We assessed a total of 71 patients with endomyocardial biopsy-proven GCM (n = 21), and CS (n = 25), as well as magnetic resonance-verified ANFM (n = 25). All echocardiographic examinations, performed upon clinical presentation, were reanalysed according to current guidelines including a detailed assessment of right ventricular (RV) dysfunction. Results: In comparison with ANFM, patients with either GCM or CS were older (mean age (±SD) 55 ± 12 or 53 ± 8 vs 25 ± 8 years), more often of female gender (52% or 24% vs 8%), had more severe clinical symptoms and higher natriuretic peptide levels. For both GCM and CS, echocardiography revealed more frequently signs of left ventricular (LV) dysfunction in form of a reduced ejection fraction (p < 0.001), decreased cardiac index (p < 0.001) and lower global longitudinal strain (p < 0.001) in contrast to ANFM. The most prominent increase in LV end-diastolic volume index was observed in CS. In addition, RV dysfunction was more frequently found in both GCM and CS than in ANFM (p = 0.042). Conclusions: Both GCM and CS have an echocardiographic and clinical appearance that is distinct from ANFM. However, the method cannot further differentiate between the two rare entities. Consequently, echocardiography can strengthen the initial clinical suspicion of a more severe form of myocarditis, thus warranting a more rigorous clinical work-up.

Tidskriftsartikel (refereegranskat)abstract
- To investigate the prognostic value of early post-transplant hemodynamic measurements on 5-year mortality in cardiac recipients (HTx).A right heart catheterization was performed in 290 heart transplantation (HTx) recipients at a one-year post-HTx evaluation. To study the effect of post-HTx hemodynamic variables on 5-year outcome, the cohort was stratified into several subgroups. For right atrial pressure (RAP), mean pulmonary artery pressure (MPAP), pulmonary artery wedge pressure (PAWP), and pulmonary vascular resistance (PVR), patients with values from the upper 10th percentile (high), were compared with those with values from the remaining lower 90th percentile (normal). For cardiac index (CI), patients with values from the lower 10th percentile (low) were compared with those with values from the remaining upper 90th percentile (normal).Death or re-transplantation within 5years after the one-year control occurred in 44 patients (13%). Of those, death or re-HTx was related to graft failure in 20 of cases (45%) and non-cardiac causes in 24 of cases (55%). The risk of death or re-HTx was higher in the subgroup with MPAP above 23mmHg than those equal to or below this value [hazard ratio 3.22, 95% confidence interval (CI) 1.49-6.97; P=0.003]. The association remained significant despite adjustment for several comorbidities. There were no differences in outcome between subgroups stratified with respect to high versus low RAP, PAWP, CI or PVR.Elevated pulmonary artery pressure at a first annual evaluation after HTx was the only hemodynamic variable that predicted impaired outcome in cardiac recipients.

Association between frailty and self-reported health following heart valve surgery
- 2020
-
Ingår i: IJC Heart & Vasculature. - : ELSEVIER IRELAND LTD. - 2352-9067. ; 31
-
Tidskriftsartikel (refereegranskat)abstract
- Background: Knowledge about the association between frailty and self-reported health among patients undergoing heart valve surgery remains sparse. Thus, the objectives were to I) describe changes in self-reported health at different time points according to frailty status, and to II) investigate the association between frailty status at discharge and poor self-reported health four weeks after discharge among patients undergoing heart valve surgery. Methods: In a prospective cohort study, consecutive patients undergoing heart valve surgery, including transapical/transaortic valve procedures were included. Frailty was measured using the Fried score, and self-reported health using the Kansas City Cardiomyopathy Questionnaire (KCCQ) and the EuroQoL-5 Dimensions 5-Levels Health Status Questionnaire (EQ-5D-5L). To investigate the association between frailty and self-reported health, multivariable logistic regression models were used. Analyses were adjusted for sex, age, surgical risk evaluation (EuroScore) and procedure and presented as odds ratios (OR) with 95% confidence intervals (CI). Results: Frailty was assessed at discharge in 288 patients (median age 71, 69% men); 51 patients (18%) were frail. In the multivariable analyses, frailty at discharge remained significantly associated with poor self-reported health at four weeks, OR (95% CI): EQ-5D-5L Index 3.38 (1.51-7.52), VAS 2.41 (1.13-5.14), and KCCQ 2.84 (1.35-5.97). Conclusion: Frailty is present at discharge in 18% of patients undergoing heart valve surgery, and being frail is associated with poor self-reported health at four weeks of follow-up. This supports a clinical need to address the unique risk of frail patients among heart valve teams broadly, and not only to measure frailty as a marker of operative risk. (C) 2020 The Authors.

Tidskriftsartikel (refereegranskat)abstract
- Introduction: Coronavirus Disease 2019 (COVID-19) has been associated with an increased risk of adverse cardiovascular events including arteriovenous thrombosis, myocarditis and acute myocardial injury. Relevant literature to date has reported widely varying estimates of mortality, ranging from approximately 2 to 11 times higher odds of mortality in COVID-19-positive STEMI (ST-segment elevation myocardial infarction) patients. Hence, we conducted this meta-analysis to resolve these inconsistencies and assess the impact of COVID-19 infection on mortality and other clinical outcomes in patients presenting with STEMI. Methods: This meta-analysis was registered in PROSPERO (CRD42021297458) and performed according to the Cochrane Handbook for Systematic Reviews of Interventions. PubMed and Embase were searched from inception to November 2021 (updated on April 2022) using a search strategy consisting of terms relating to COVID-19, STEMI, and mortality. Results: We identified 435 studies through our initial search. After screening according to our eligibility criteria, a total of 11 studies were included. Compared with the non-COVID-19 STEMI patients, the in-hospital mortality rate was higher in COVID-19-positive STEMI patients. Similarly, the risk of cardiogenic shock was higher in the COVID-19-positive patients. Length of hospital stay was longer in STEMI patients with COVID-19. Conclusions: Our study highlights the necessity for early evaluation of COVID-19 status in all STEMI patients followed by risk stratification, prompt reperfusion and more aggressive management of COVID-19-positive patients. Further research is needed to elucidate the mechanisms behind poorer prognosis in such patients.

- Background: Heart failure represents a major public health issue that impacts 26 million people globally. Currently, real-world data represents a key instrument for providing the verification of both internal and external validity, yet there is still a lack of understanding regarding its scope in complementing evidence of treatments for heart failure. This study aims to increase understanding of the utilisation of real-word data from heart failure registries in Organisation for Economic Co-operation and Development (OECD) countries.Method: This was a systematic review of existing observational studies from heart failure registries in 35 OECD member countries. Studies from 2000 to March 2017 were identified through electronic databases (MEDLINE (Ovid), EMBASE, Web of Science Core Collection, CINAHL (Ebsco), Cochrane CENTRAL) and appraised according to eligibility criteria.Results: Two-hundred and two studies met the inclusion criteria, in which the majority were published from 2013 to 2016. All 202 studies were observational, among which 98% were cohort studies (198). The median sample size of all studies was 5152 (2417 to 32,890) and median study period 55 months (33.0 to 72.0). Swedish heart failure registry had the most publications (24, 12%).Conclusion: Since 2000 there has been an upward trend in the number of published observational studies on heart failure registries in OECD countries with increasingly diverse outcomes and advanced statistical methods to improve their validity and reliability. This indicates that the utilisation of real-world data has experienced a significant upsurge in complementing the findings of clinical trials for improved research of heart failure treatments.

- To evaluate the role of baseline 12‑lead ECG in predicting the syncope mechanism during continuous monitoring using an implantable loop recorder (ILR).Consecutive patients with syncope implanted with an ILR were enrolled. Baseline 12‑lead ECG were related to ECG diagnosis derived from ILR tracings recorded at the time of syncope recurrence.In total 300 patients with a mean age of 66±16years were included, 49% (146/300) received an ILR-guided diagnosis during follow-up. Patients with abnormal baseline ECG more frequently received an ILR-guided diagnosis compared to those with normal baseline ECG 59% vs. 44%, p=0.018. For a diagnosis of arrhythmic syncope, the corresponding frequencies were 45% vs. 26%, p=0.001.Patients with bifascicular block significantly more common received an ILR-guided diagnosis 76% (25/33) compared to those with normal baseline ECG 44% (90/205), p≪0.001. In this subgroup, 96% (24/25) were diagnosed with arrhythmic syncope, 23 of which were due to bradyarrhythmia. Bifascicular block occurred almost exclusively among those ≥60years (31/33). After logistic regression the adjusted OR for arrhythmic syncope was significant for bifascicular block 5.5 (95%CI 2.3-13.2), p≪0.001. PPV for bifascicular block in predicting arrhythmic syncope was 73% and NPV 73%.A baseline 12‑lead ECG with bifascicular block was a strong predictor for syncope during follow-up, most often due to bradyarrhythmia caused by intermittent complete heart block. No other ECG findings were associated with the ILR outcome. We find it reasonable to consider permanent pacing instead of an ILR for patients with bifascicular block and unexplained syncope.

Tidskriftsartikel (refereegranskat)abstract
- Background: While the clinical importance of cardiac troponin is well-known in type 1 myocardial infarction (MI), evidence on this topic in type 2 MI is limited. We assessed the clinical and prognostic implications of high sensitivity cardiac troponin (hs-cTnT) concentrations in a large sample of patients with type 2 MI.Methods: Retrospective registry-based cohort study (SWEDEHEART) including 4607 patients with type 2 MI and 43,405 patients with type 1 MI, used for comparisons. Patients with ST-elevation MI were excluded. Multivariable-adjusted regressions were applied to investigate the associations of hs-cTnT concentrations (highest measured value during each hospitalization) with clinical variables and prognosis during a median follow-up of up to 1.9 years.Results: Hs-cTnT concentrations (median 264 [25th, 75th percentiles 112-654] ng/L) were significantly associated with various cardiovascular risk factors and comorbidities in type 2 non-ST elevation MI (NSTEMI) but only weakly with the underlying triggering condition. Most of these findings including the magnitude of hs-cTn release were similar to type 1 NSTEMI. Hs-cTnT (ln) independently predicted all-cause mortality (hazard ratio 1.13 [95% confidence interval 1.09-1.17]) and major adverse events (hazard ratio 1.13 [95% confidence interval 1.10-1.17]) in type 2 NSTEMI, similar as for type 1 NSTEMI according to interaction analysis. The associations of hs-cTnT (ln) with poor prognosis tended to be stronger in type 2 NSTEMI patients without known cardiovascular disease.Conclusions: Hs-cTnT concentrations independently predict adverse outcome in type 2 NSTEMI. The similarities to type 1 NSTEMI however, are striking and emphasize the difficulty to distinguish both MI types.

Forskningsöversikt (refereegranskat)abstract
- Coronary artery disease (CAD) is the most prevalent and single most common cause of morbidity and mortality [1] with the resulting left ventricular (LV) dysfunction an important complication. The distinction between viable and non-viable myocardium in patients with LV dysfunction is a clinically important issue among possible candidates for myocardial revascularization. Several available non-invasive techniques are used to detect and assess ischemia and myocardial viability. These techniques include echocardiography, radionuclide images, cardiac magnetic resonance imaging and recently myocardial computed tomography perfusion imaging. This review aims to distinguish between the available non-invasive imaging techniques in detecting signs of functional and perfusion viability and identify those which have the most clinical relevance in detecting myocardial viability in patients with CAD and chronic ischemic LV dysfunction. The most current available studies showed that both myocardial perfusion and function based on non-invasive imaging have high sensitivity with however wide range of specificity for detecting myocardial viability. Both perfusion and function imaging modalities provide complementary information about myocardial viability and no optimum single imaging technique exists that can provide very accurate diagnostic and prognostic viability assessment. The weight of the body of evidence suggested that non-invasive imaging can help in guiding therapeutic decision making in patients with LV dysfunction.

Tidskriftsartikel (refereegranskat)abstract
- Background: Immediate coronary angiography with subsequent percutaneous coronary intervention (PCI) has the potential to reduce post-resuscitation myocardial dysfunction in out-of-hospital cardiac arrest (OHCA) patients. The aim of this study was to see if immediate coronary angiography, with potential PCI, in patients without ST-elevation on the ECG, influenced post-resuscitation myocardial function and cardiac biomarkers.Methods: A secondary analysis of the Direct or Subacute Coronary Angiography in Out-of-Hospital Cardiac Arrest (DISCO) trial (ClinicalTrials.gov ID: NCT02309151). Patients with bystander-witnessed OHCA, without ST-elevations on the ECG were randomly assigned to immediate coronary angiography within two hours of cardiac arrest (n = 38) versus standard-of-care with deferred angiography (n = 40). Outcome measures included left ventricle ejection fraction (LVEF) at 24 h, peak Troponin T levels, lactate clearance and NT-proBNP at 72 h.Results: In the immediate-angiography group, median LVEF at 24 h was 47% (Q1-Q3; 30-55) vs. 46% (Q1-Q3; 35-55) in the standard-of-care group. Peak Troponin-T levels during the first 24 h were 362 ng/L (Q1-Q3; 174-2020) in the immediate angiography group and 377 ng/L (Q1-Q3; 205-1078) in the standard-of-care group. NT-proBNP levels at 72 h were 931 ng/L (Q1-Q3; 396-2845) in the immediate-angiography group and 1913 ng/L (Q1-Q3; 489-3140) in the standard-of-care group.Conclusion: In this analysis of OHCA patients without ST-elevation on the ECG randomized to immediate coronary angiography or standard-of-care, no differences in post-resuscitation myocardial dysfunction parameters between the two groups were found. This finding was consistent also in patients randomized to immediate coronary angiography where PCI was performed compared to those where PCI was not performed.

Tidskriftsartikel (refereegranskat)abstract
- Background: Among international cardiologists it is unclear whether equipoise exists regarding the benefit of diagnosing and managing obstructive sleep apnea (OSA) to improve atrial fibrillation (AF) outcomes and whether clinical practice and equipoise are linked. Methods: Between January 2019 and June 2020 we distributed a web-based 12-question survey regarding OSA and AF management to practicing cardiologists in 16 countries. Results: The United States, Japan, Sweden, and Turkey accounted for two-thirds of responses. 863 cardiologists responded; half were general cardiologists, a quarter electrophysiologists. Responses regarding treating OSA with CPAP to improve AF endpoints were mixed. 33% of respondents referred AF patients for OSA screening. OSA was diagnosed in 48% of referred patients and continuous positive airway pressure (CPAP) was prescribed for 59% of them. Nearly 70% of respondents believed randomized controlled trials (RCTs) of OSA treatment in AF patients were necessary and indicated willingness to contribute to such trials. Conclusions: There was no clinical equipoise among surveyed cardiologists; a majority expressed certainty that combined OSA and AF treatment is superior to AF treatment alone for improving AF outcomes. However, a minority of surveyed cardiologists referred AF patients for OSA testing, and while half of screened AF patients had OSA, CPAP was prescribed in little more than half of them, reflecting the view that better clinical trial evidence is needed to support this practice. Our results underscore the need for larger, multi-national prospective studies of OSA treatment and AF outcomes to inform more uniform society guideline recommendations.

-
Tidskriftsartikel (refereegranskat)abstract
- Aim: The aim of this study was to evaluate the relationship between coronary artery calcification (CAC) assessed by multi-detector computed tomography (MDCT) and myocardial perfusion assessed by cardiac magnetic resonance imaging (CMR) in a group of symptomatic patients. Method: Retrospective analysis of 120 patients (age 65.1 +/- 8.9 years, 88 males) who presented with atypical chest pain to Bethanien Hospital, Frankfurt, Germany, between 2007 and 2010 and who underwent CAC scoring using MDCT, CMR, and conventional coronary angiography. Patients were divided into those with high-grade (HG) stenosis (n = 67, age 65.1 +/- 9.4 years) and those with no-HG stenosis (n = 53, age 65.1 +/- 8.6 years). Results: There were more males with HG stenosis (82.1% vs. 62.3%, p = 0.015), in whom the percentage and number of abnormal perfusion segments were higher at rest (37.3% vs. 17%, p = 0.014) but not different with stress (p = 0.83) from those with no-HG stenosis. Thirty-four patients had myocardial perfusion abnormalities at rest and 26 patients developed perfusion defects with stress. Stress-induced myocardial perfusion defects were 22.4% sensitive and 79.2% specific for detecting HG stenosis. The CAC score was lower in patients with no-HG stenosis compared to those with HG stenosis (p < 0.0001). On the ROC curve, a CAC score of 293 had a sensitivity of 71.6% and specificity of 83% in predicting HG stenosis [(AUC 0.80 (p < 0.0001)]. A CAC score of 293 or the presence of at least 1 segment myocardial perfusion abnormality was 74.6% sensitive and 71.7% specific in detecting HG stenosis, the respective values for the 2 abnormalities combined being 19.4% and 90.6%. The severity of CAC correlated with the extent of myocardial perfusion in the patient group as a whole with stress (r = 0.22, p = 0.015), particularly in those with no-HG stenosis (r = 0.31, p = 0.022). A CAC score of 293 was 31.6% sensitive and 87.3% specific in detecting myocardial perfusion abnormalities. Conclusion: In a group of patients with exertional angina, coronary calcification is more accurate in detecting high-grade luminal stenosis than myocardial perfusion defects. In addition, in patients with no stenosis, the incremental relationship between coronary calcium score and the extent of myocardial perfusion suggests coronary wall hardening as an additional mechanism for stress-induced angina other than luminal narrowing. These preliminary findings might have a clinical impact on management strategies of these patients other than conventional therapy.

- Aims: To assess the relation between atrial fibrillation (AF) characteristics and health-related quality of life (QoL), and which AF characteristic had the greatest impact.Method: The AF characteristics burden (percentage of time in AF), duration and number of AF episodes/month were obtained from implantable cardiac monitors during the 2-month run-in period in 150 patients included in the randomized CAPTAF trial comparing early ablation and antiarrhythmic drug therapy. The QoL was measured by the General Health and Vitality dimensions of the 36-Item Short-Form Health Survey. AF characteristics were analysed continuously and in quartiles (Q1-Q4).Results: Greater AF burden (p = 0.003) and longer AF episodes (p = 0.013) were associated with impaired QoL (Vitality score only) in simple linear regression analyses. Greater AF burden was, however, the only AF characteristic associated with lower QoL, when adjusted for sex, type of AF, hypertension, heart rate above 110 beats per minute during AF, and beta-blocker use in multiple linear regression analyses. For every 10% increase in AF burden there was a 1.34-point decrease of Vitality score (95% confidence interval (CI) -2.67 to -0.02, p = 0.047). The Vitality score was 12 points lower (95% CI -22.73 to -1.27, p = 0.03) in patients with an AF burden > 33% (Q4) versus those with < 0.45% (Q1), but only in unadjusted analysis.Conclusion: AF burden had a greater impact on QoL (Vitality), than the duration and number of AF episodes, corroborating that AF burden may be the preferred outcome measure of rhythm control in trials including relatively healthy AF populations.

Tidskriftsartikel (refereegranskat)abstract
- Background: Although a large number of studies on heart failure with reduced ejection fraction (HFrEF) have found that anemia and renal dysfunction (RD) independently predicted poor outcomes, there are still few reports on patients with heart failure with preserved ejection fraction (HFpEF). Methods: Clinical data of HFpEF patients registered in the China National Heart Failure Registration Study (CN-HF) were evaluated and the clinical features of patients with or without anemia/RD were compared to explore the impact of anemia and RD on all-cause mortality and all-cause re-hospitalization. Results: 1604 patients with HFpEF were enrolled, the prevalence of anemia was 51.0%. Although anemia was associated with increased risk of all-cause mortality and all-cause re-hospitalization in univariate COX regression (p < 0.05), multivariate COX model confirmed that anemia was not independently associated with all-cause mortality [hazard ratio (HR) 1.14, 95% confidence interval (CI) 0.85–1.52, p = 0.386] and all-cause re-hospitalization (HR 1.13, 95% CI 0.96–1.33, p = 0.152). Similarly, RD was not an independent predictor of all-cause mortality (HR 1.18, 95% CI 0.88–1.57, p = 0.269) and all-cause re-hospitalization (HR 0.94, 95% CI 0.79–1.12, p = 0.488) as assessed in the adjusted COX regression model. The interaction between RD and anemia on end-points events was also not statistically significant. However, anemia was associated with increased all-cause re-hospitalization in patients with New York Heart Association (NYHA) class III-IV. Conclusions: In patients with HFpEF from CN-HF registry, anemia was common, but was not an independent predictor of all-cause mortality and all-cause re-hospitalization, except for the all-cause re-hospitalization in patients with NYHA class III-IV.

- Background: Physical activity reduces the risk of acquired cardiovascular disease, which is of great importance in patients with congenital heart disease (CHD). There are diverging data whether physical activity level (PAL) differs between patients with CHD and controls. Furthermore, it is unknown if PAL can be reliably assessed in patients with CHD using self-reported instruments. Methods: Seventy-five patients with CHD (mean age 37.5 ± 15.5 years, women n = 29 [38.7%]) and 42 age and sex matched controls completed the International Physical Activity Questionnaire (IPAQ) and carried the activity monitor Actiheart over 4 days. Time spent at ≥3 METS ≥21.4 min/day, i.e. reaching the WHO recommendation for PAL to promote health, was used as the outcome measure. Data on PAL obtained from IPAQ were compared with Actiheart. Results: The proportion of individuals reaching target PAL according to IPAQ was similar in patients with CHD and controls (70.7%vs.76.2%, p = 0.52) as well as between patients with simple and complex lesions. There was an overall difference between IPAQ and Actiheart in detecting recommended PAL (72.6%vs.51.3%, p < 0.001). In a subgroup analysis, this difference was also detected in patients but was borderline for controls. The negative predictive value for IPAQ in detecting insufficient PAL was higher in patients than in controls (73%vs.40%). Conclusions: The proportion of persons reaching sufficient PAL to promote health was similar in patients and controls. The self-reported instrument overestimated PAL in relation to objective measurements. However, with a high negative predictive value, IPAQ is a potentially useful tool for detecting patients with insufficient PAL.

- Physical activity is important to maintain and promote health. This is of particular interest in patients with congenital heart disease(CHD) where acquired heart disease should be prevented. The World Health Organization (WHO) recommends a minimum of 2.5 h/week of physical activity exceeding 3 metabolic equivalents (METS) to achieve positive health effects. It is unknown whether physical activity levels (PAL) in adult CHD patients differ by country of origin.Methods3896 adults with CHD recruited from 15 countries over 5 continents completed self-reported instruments, including the Health Behaviour Scale (HBS-CHD), within the APPROACH-IS project. For each patient, we calculated whether WHO recommendations were achieved or not. Associated factors were investigated using Generalized Linear Mixed Models.ResultsOn average, 31% reached the WHO recommendations but with a great variation between geographical areas (India: 10%–Norway: 53%). Predictors for physical activity level in line with the WHO recommendations, with country of residence as random effect, were male sex (OR 1.78, 95%CI 1.52–2.08), NYHA-class I (OR 3.10, 95%CI 1.71–5.62) and less complex disease (OR 1.46, 95%CI 1.16–1.83). In contrast, older age (OR 0.97, 95%CI 0.96–0.98), lower educational level (OR 0.41, 95%CI 0.26–0.64) and being unemployed (OR 0.57, 95%CI 0.42–0.77) were negatively associated with reaching WHO recommendations.ConclusionsA significant proportion of patients with CHD did not reach the WHO physical activity recommendations. There was a large variation in physical activity level by country of origin. Based on identified predictors, vulnerable patients may be identified and offered specific behavioral interventions.

Tidskriftsartikel (refereegranskat)abstract
- Background: The objectives of the study were to describe positron emission tomography (PET) parameters, using the tracers O-15-water at rest/stress, C-11-acetate, and C-11-HED, with regard to nonsustained ventricular tachycardia (NSVT) in hypertrophic cardiomyopathy (HCM). PET offers quantitative assessment of pathophysiology throughout the left ventricular segments, including the endocardium/epicardium. The potential use PET in risk stratification remains to be elucidated. NSVT provides a marker for sudden cardiac death.Methods: Patients with a validated diagnosis of HCM who had an implantable cardioverter-defibrillator were interrogated at 12 months and independently of PET-examinations.Results: In total, 25 patients (mean age 56.8 +/- 12.9 years, 76% males) were included and 10 reported NSVT. Mean myocardial blood flow (MBF) at rest was 0.91 ml/g/min and decreased at stress, 1.59 ml/ g/min. The mean gradient (endocardium/epicardium quotient) at rest was 1.14 +/- 0.09, while inverse at stress (mean 0.92 +/- 0.16). Notably, MBF gradient at stress was significantly lower in patients with NSVT (p = 0.022) and borderline at rest (p = 0.059) while global MBF at rest and stress were not. Mean myocardial oxygen consumption (MVO2) was 0.088 ml/g/min (higher in NSVT, p = 0.023) and myocardial external efficiency 18.5%. Using C-11-HED, the mean retention index was 0.11 min (1) and a higher volume of distribution (p = 0.089) or transmural gradient of clearance rate (p = 0.061) or lower clearance rate (p = 0.052) showed a tendency of association of NSVT.Conclusions: The endocardium/epicardium MBF gradient at stress is significantly lower in HCM patients with NSVT. This provides a novel approach to further refine risk stratification of sudden cardiac death.

- AimExertional angina in patients with no coronary flow limiting lesions remains a clinical puzzle. We aimed to assess the extent of coronary artery calcification (CAC) and its relationship to ventricular wall motion function using stress echocardiography in a group of patients limited by exertional angina, but no obstructive lesions.MethodsWe compared CT coronary calcium score (CACS) and dobutamine stress echocardiography in 55 patients (age 64.7 ± 7.7 years), divided into Group 1 (CACS ≤ 100) and Group 2 (CACS > 100). No patient had LV ejection fraction-EF < 55%, pulmonary hypertension, arrhythmia, renal failure or parathyroid disease. Multiple linear regression analysis was used to test the association between gender-standardized continuous echocardiographic parameters and patient groups adjusted for age, body surface area, osteoporosis and CV risk factors and CACS.ResultsAt rest, LV long axis ‘subendocardial’ function was reduced (amplitude: β − 1.11 SD, p < 0.05, R2 0.6 and systolic velocity: β − 1.08 SD, p < 0.05, R2 0.44), left atrial (LA) indexed volume was raised (β 1.06 SD, p < 0.05, R2 0.37) and its systolic velocity decreased (β − 1.05 SD, p < 0.05, R2 0.35) in Group 2. With stress, wall motion score index increased (p < 0.05) and long axis disturbances worsened only in the same group. Multivariate analysis demonstrated clear relationship between ischaemic LV disturbances, reduced long axis amplitude, global longitudinal systolic strain and early diastolic strain rate. Resting and stress RV lengthening velocity also correlated with CAC score.ConclusionIn symptomatic patients with no obstructive coronary lesions and with more than mild CAC, long axis disturbances and wall motion score index rise occur with stress, at the time of symptom development and correlate with severity of arterial calcification. These findings suggest CAC as a potential mechanism for coronary wall stiffness and consequently exertional ischaemic changes as a result of limited flow reserve.

- OBJECTIVE: A bicuspid aortic valve (BAV) is associated with accelerated aortic valve disease (AVD) and abnormalities in aortic elasticity. We investigated the intima-media thickness of the descending aorta (AoIMT) in patients with AVD with or without an ascending aortic aneurysm (AscAA), in relation to BAV versus tricuspid aortic valve (TAV) phenotype, type of valve disease, cardiovascular risk factors, and single-nucleotide polymorphisms (SNPs) with a known association with carotid IMT. METHODS AND RESULTS: 368 patients (210 with BAV, 158 with TAV,); mean age 64 +/- 13 years) were examined using transesophageal echocardiography (TEE) before valvular and/or aortic surgery. No patient had a coronary disease (CAD). The AoIMT was measured on short-axis TEE images of the descending aorta using a semi-automated edge-detection technique. AoIMT was univariately (P < 0.05) related to age, blood pressure, smoking, creatinine, highly sensitive C-reactive protein, HDL, valve hemodynamics and BAV. In the TAV subgroup it was also associated with the rs200991 SNP. Using multivariate regression analysis, age was the main determinant for AoIMT (P < 0.001), followed by male gender (P = 0.02), BAV was no longer a significant predictor of AoIMT. AoIMT was still related to the rs200991 SNP in TAV (P = 0.034), and to creatinine in BAV (P = 0.019), when other variables were accounted for. CONCLUSIONS: Intima-media thickness of the descending aorta is not affected by aortic valve morphology (BAV/TAV); age is the main determinant of AoIMT. Genetic markers (SNPs) known to influence IMT in the carotid artery seem to correlate to IMT in the descending aorta only in patients with TAV.

Tidskriftsartikel (refereegranskat)abstract
- Background: Coronary artery disease (CAD) is a leading cause of death worldwide and increasing cost for society. Genome wide association studies (GWAS) have identified common variants associated with CAD. Combining single nucleotide polymorphisms (SNPs) into a genetic risk score (GRS) can estimate an individual's genetic burden. Objectives: To investigate whether GRS for CAD can predict hospitalization and mortality. Methods: 23,594 individuals without CAD at baseline and with full data for all covariates from the population based prospective study Malmö diet and cancer study were investigated. The association between hospitalizations was calculated by negative binomial regression and risk of mortality was calculated by Cox proportional hazards regression. The GRS was constructed from 50 SNPs. Results: The study population was divided into quintiles according to the value of GRS. During the mean follow-up time of 17.8 years, 17,254 individuals were hospitalized at least once. Individuals in the highest quintile of GRS were hospitalized 10% more often than individuals in the lowest quintile (IRR: 1.10 [95% CI 1.04–1.16], p = 0.001), mainly for cardiovascular reasons (IRR: 1.31 [95% CI 1.20–1.43], p = 5.17 × 10−10). These individuals had highly increased risk of CVD mortality (HR: 1.44 [1.25–1.66], p = 6.56 × 10−7) but not the risk of mortality due to other causes. Conclusion: Our results suggest that genetic predisposition for CAD can predict hospitalization burden and mortality, especially due to cardiovascular causes, independently of traditional risk factors. As the risk conferred by the GRS is partially modifiable, our results may help to reduce societal costs, individual suffering and prolong life.

Tidskriftsartikel (refereegranskat)abstract
- Background: Extracellular vesicles (EVs) are thought to exert protective effects after ischemic and remote ischemic preconditioning. It is not well understood which EV content factors are most relevant for protective effects. We hypothesize that ischemic preconditioning leads to qualitative changes in EV mRNA content and quantitative changes in EV size and number.Methods: Using an in vivo porcine ischemic preconditioning model, EVs were collected from coronary venous blood, and isolated by differential ultracentrifugations. The presence and purity of EV were verified by electron microscopy and Western blot, and EV number was assessed by nanoparticle tracking analysis. The mRNA EV was identified by microarray.Results: Gene ontology analysis showed enrichment of EV mRNA coding for proteins associated with regulation of transcription, translation, extracellular matrix, morphogenic development and feeding behavior. There were 11,678 different mRNA transcripts detected in EV, where a total of 1103 was significantly increased or decreased after preconditioning, of which 638 mRNA sequences were up-regulated and/or emerged due to preconditioning. Several of them have known association with ischemic preconditioning. There was no significant difference in EV quantity or size before and after preconditioning.Conclusions: These findings demonstrate in an in vivo model that myocardial ischemic preconditioning influences the composition of mRNA in EV, including gene transcripts for proteins associated with the protective effect of ischemic preconditioning. The finding that preconditioned parental cells release EV containing mRNA that is qualitatively different from those released by non-preconditioned cells shows the importance of the external milieu on parental cell EV production.

Tidskriftsartikel (refereegranskat)abstract
- Background: The incidence of atrial fibrillation (AF) has long been increasing, and AF is associated with increased mortality. Over time, mortality trends may differ between subgroups depending on their underlying risk patterns and treatments. Aim: To explore all-cause-mortality trends over time in patients hospitalized for incident AF, and the effects of age, stroke risk, and education level. Methods and results: Patients hospitalized for incident AF between January 1995 and December 2003 were selected from Swedish national registries. Based on date of index admission, patients were divided into four cohorts and followed for five years. Age- and sex-matched controls were selected. Kaplan-Meier estimates and Cox regressions with trend analysis were used for statistical evaluation. There were 64,489 patients (mean age 72 +/- 10.1 years) and 116,893 controls. There was a significantly decreasing trend in the relative risk of all-cause mortality in AF patients over time, with a trend hazard ratio of 0.94 (95 % confidence interval [CI] 0.92-0.96, p < 0.001) in women and 0.91 (95 % CI 0.89-0.93, p < 0.001) in men. The mortality trends did not differ significantly between AF patients and controls. The mortality risk remained unchanged in women aged 18-64 years, in patients with low stroke risk, and in patients with post-secondary education. Conclusion: The all-cause mortality risk decreased over time in both patients and controls, but subgroup analysis revealed an unchanged mortality trend in women aged 18-64 years, in patients with low stroke risk, and in patients with post-secondary education.

Tidskriftsartikel (refereegranskat)abstract
- Background: Patients with cyanotic congenital heart disease (CCHD) may have a low burden of atherosclerosis. Endothelial dysfunction is an early stage of atherosclerosis and endothelial function is previously studied in smaller CCHD groups with different techniques and variable results. We aimed to examine endothelial function and carotid atherosclerosis in a larger group of CCHD patients. Methods: This multicentre study assessed endothelial function in adults with CCHD and controls by measuring the dilatory response of the brachial artery to post-ischemic hyperaemia (endothelium-dependent flow-mediated-vasodilatation (FMD)), and to nitroglycerin (endothelium-independent nitroglycerin-induced dilatation (NID)). Flow was measured at baseline and after ischaemia (reactive hyperaemia). Carotid-intima-media-thickness (CIMT), prevalence of carotid plaque and plaque thickness (cPT-max) were evaluated ultrasonographically. Lipoproteins, inflammatory and vascular markers, including sphingosine-1-phosphate (S1P) were measured. Results: Forty-five patients with CCHD (median age 50 years) and 45 matched controls (median age 52 years) were included. The patients presented with lower reactive hyperaemia (409 ± 114% vs. 611 ± 248%, p < 0.0001), however preserved FMD response compared to controls (106.5 ± 8.3% vs. 106.4 ± 6.1%, p = 0.95). In contrast, NID was lower in the patients (110.5 ± 6.1% vs. 115.1 ± 7.4%, p = 0.053). There was no difference in CIMT, carotid plaque or cPT-max. The patients presented with lower high-density-lipoprotein cholesterol, and higher level of inflammatory markers and S1P. Conclusion: Adults with CCHD had preserved FMD in the brachial artery, but impaired NID response and lower reactive hyperaemia than controls. The preserved FMD and the comparable prevalence of carotid atherosclerosis indicate that CCHD patients have the same risk of atherosclerosis as controls.

- Background: Assessment of pulmonary vascular resistance (PVR) is critical for accurate diagnosis and optimal pharmacotherapy in pulmonary hypertension. We aimed to test the diagnostic performance of a novel, Doppler-based method to evaluate PVR based on Ohm’s law (PVRecho) using pragmatic estimates of pulmonary capillary wedge pressure (PCWP).Methods and results: Simultaneous right heart catheterization (RHC) and echocardiography was performed in a derivation cohort of 111 patients in sinus rhythm referred for PH evaluation and PVRecho independently validated in 238 patients. PVRecho was calculated using pulmonary artery mean pressure estimates (PAMPecho) obtained from peak tricuspid gradient employing a fixed right atrial pressure estimate, PCWPecho was estimated as 10 or 20 mmHg using age-related mitral E/A cut-offs and cardiac output from left ventricular outflow. In the derivation cohort, both PAMPecho and PCWPecho estimates demonstrated excellent agreement with catheterization measurements. PVRecho was highly feasible, demonstrated negligible bias and excellent agreement with PVRRHC (Bias = −0.58, SD 2.2 mmHg) and outperformed the Abbas method to identify PVRRHC > 3WU (AUC = 0.85 vs. 0.70; p = 0.02). In the validation cohort, PVRecho preserved good invasive agreement with negligible bias, displayed strong diagnostic performance (AUC = 0.84) and significant ability to distinguish isolated post-capillary from combined post- and pre-capillary pulmonary hypertension (PH) subgroups (AUC = 0.77).Conclusion: PVRecho based on Ohm’s law employing pragmatic estimates of PCWPecho demonstrates excellent agreement with invasive reference standard measurements and strong diagnostic ability to identify elevated PVRRHC. This novel approach may be useful during therapy selection to distinguish PH hemodynamic subgroups.

- INTRODUCTION: Patients with paroxysmal atrial fibrillation experience low health-related quality of life which can be improved by performing yoga. The aim of this study was to evaluate gender differences in health-related quality of life, blood pressure and heart rate among patients with paroxysmal atrial fibrillation after performing MediYoga.METHODS: This is a secondary analysis of subgroups, investigating the yoga groups, from two randomized controlled trials (RCT 1: yoga group versus control group, RCT 2: a three-armed randomized study with yoga, control and relaxation groups). The yoga groups performed MediYoga for one hour/week over a 12-week period in both studies. Quality of life (SF-36), blood pressure and heart rate were collected at baseline and end of study.RESULTS: No differences were found between the women and men. Within the women's group, there were improvements in vitality (p = 0.011), social function (p = 0.022), mental health (p = 0.007) and Mental Components Summary (p = 0.022). There were differences within the men's group in bodily pain (p = 0.005), general health (p = 0.003), vitality (p = 0.026), social function (p = 0.005), role-emotion (p = 0.011) and Mental Components Summary (p = 0.018). Within the women's group, differences were observed in systolic blood pressure (p = 0.010) and diastolic blood pressure (p = <0.001). The men's group also showed improvement in diastolic blood pressure (p = 0.021).CONCLUSION: MediYoga improved mental health as well as diastolic blood pressure in both men and women with PAF. This study suggests that both men and women, with PAF, may benefit from complementary treatment such as yoga.Clinical Trial Gov Id: NCT01789372.

- Previous studies comparing electrocardiogram (ECG) in Takotsubo syndrome (TS) versus ST elevation myocardial infarction (STEMI) included TS patients without ST elevation, did not consider the culprit lesion in STEMI or had groups that were unbalanced regarding sex and age. Accounting for these factors, we sought to conduct a more reliable comparison of ECG in TS with ST-elevation (STE-TS) versus STEMI. The secondary aim was to investigate if ST segment changes, T wave inversion or prolonged QT interval predicted ventricular arrhythmia or death in STE-TS and STEMI.All STE-TS patients who presented at Sahlgrenska University Hospital between 2008 and 2019 were matched by sex and age to STEMI patients. STEMI patients were subcategorized according to whether or not the culprit lesion was located in the left anterior descending artery (LAD). Baseline characteristics, in-hospital outcomes and admission ECGs were analyzed.104 STE-TS patients were sex- and age-matched with 274 STEMI patients (113 LAD-STEMI, 161 non-LAD STEMI). Admission ECG in STE-TS was more similar to LAD STEMI than non-LAD STEMI. Reciprocal ST depression was less common in STE-TS (7/104, 6.7%) compared with STEMI (112/274, 41%; p=<0.001). The sum of all ST elevations and the sum of all ST-deviations predicted life-threatening ventricular arrhythmia (LTVA) or death in LAD STEMI but not in STE-TS.In conclusion, admission ECG in STE-TS was similar to LAD STEMI but reciprocal ST depression was less common in STE-TS compared with STEMI overall. ST segment changes predicted LTVA or death in STEMI but not in STE-TS.

- Electrocardiography (ECG) on admission is similar in ST elevation myocardial infarction (STEMI) and Takotsubo syndrome (TTS). ECG on admission has been extensively investigated and compared between STEMI and TTS, however, only a few studies have compared temporal ECG. Our aim was to compare ECG in anterior STEMI versus female TTS from admission to day 30.Adult patients with anterior STEMI or TTS treated at Sahlgrenska University Hospital (Gothenburg, Sweden) from December 2019 to June 2022 were prospectively enrolled. Baseline characteristics, clinical variables and ECGs from admission to day 30 were analyzed. Using a mixed effects model, we compared temporal ECG between female patients with anterior STEMI or TTS, as well as between female and male patients with anterior STEMI.A total of 101 anterior STEMI patients (31 female, 70 male) and 34 TTS patients (29 female, 5 male) were included. The temporal pattern of T wave inversion was similar between female anterior STEMI and female TTS, as well as between female and male anterior STEMI. ST elevation was more common, whereas QT prolongation was less common, in anterior STEMI compared with TTS. Q wave pathology was more similar between female anterior STEMI and female TTS than between female and male anterior STEMI.The pattern of T wave inversion and Q wave pathology from admission to day 30 was similar in female patients with anterior STEMI and female patients with TTS. Temporal ECG in female patients with TTS may be interpreted as following a "transient ischemic" pattern.

- Objective: Interactive patient education, referred to as Heart School (HS), is an important part of cardiac rehabilitation (CR) after myocardial infarction (MI), which has been associated with improved outcomes. Little is known about HS attendance among foreign-born patients. The aims were to assess; 1) HS attendance in foreign-born versus native-born patients, 2) the association between the provision of professional interpreters and HS attendance, and 3) secondary prevention goal attainment after MI based on HS attendance. Methods: The provision of professional interpreters during post-MI follow-up was assessed by a questionnaire sent to all 78 Swedish CR sites. Patient-specific data was retrieved from the SWEDEHEART registry. The association between the provision of professional interpreters and HS attendance was estimated with logistic regression models. HS attendance and attainment of secondary prevention goals by country of birth were investigated. Results: In total, 8377 patients < 75 years (78 % male) were included. Foreign-born (19.8 %) had a higher prevalence of cardiovascular risk factors and were less likely to attend HS (33.7 vs 51.3 %, p < 0.001), adjusted odds ratio (OR) 0.59 (95 % confidence interval (CI) 0.52–0.68), compared with native-born patients. CR centers providing professional interpreters had higher HS attendance among foreign-born (adjusted OR 1.55, 95 % CI 1.20–2.01) but not among native-born patients. Attending HS was similarly associated with improved secondary prevention goal attainment in both groups. Conclusions: Despite similar positive association between HS attendance and attainment of secondary prevention goals, foreign-born patients attended HS less often. With the provision of professional interpreters, HS attendance increased in foreign-born patients.
