- Background: 1% of all live born children are born with a congenital heart defect (CHD) and currently 95% reach adulthood. Type 1 diabetes mellitus (T1DM) is an autoimmune disease that can develop due to i.e. heredity, exposure to infections and stress-strain. The incidence of T1DM in patients with CHD is unknown and we analysed the risk of developing T1DM for patients with CHD, and how this influences mortality. Methods: By combining registries, the incidence of T1DM and the mortality was analysed in patients with CHD by birth cohort (1970–1993, 1970–1984 and 1984–1993) matched with population-based controls matched for sex, county and year of birth without CHD and followed from birth until a maximum of 42 years. Results: 221 patients with T1DM among 21,982 patients with CHD and 1553 patients with T1DM among 219,816 matched controls were identified. The hazard ratio (HR) for developing T1DM was 1.50 (95%, CI 1.31–1.73) in patients with CHD compared to the controls and the first birth cohort (1970–1984) had the highest risk for T1DM, HR 1.87 (95%, CI 1.56–2.24). After onset, mortality risk was 4.21 times higher (95%, CI 2.40–7.37) in patients with CHD and T1DM compared to controls with T1DM. Conclusion: From a nationwide cohort of patients with CHD and controls, the incidence of developing T1DM was 50% higher in patients with CHD, showing a significant increase in risk among birth cohort 1970–1984. The combination of CHD and T1DM was associated with a 4-fold increase in mortality compared to controls with only T1DM. © 2020

- The relationship between various categories of blood pressure (BP), subtypes of hypertension, and development of cardiovascular disease (CVD) have not been extensively studied. Therefore, our study aimed to explore this relationship in a random population sample of men born in 1943, living in Sweden and followed over a 21-year period.Participants were examined for the first time in 1993 (age 50 years), where data on medical history, concomitant diseases, and general health were collected. The examination was repeated in 2003 and with additional echocardiography also in 2014. Classification of participants according to their BP at the age of 50 years was as follows: optimal-normal BP (systolic blood pressure [SBP] <130 and diastolic BP [DBP] <85mmHg), high-normal BP (130≤SBP<140, 85≤DBP<90mmHg), isolated systolic-diastolic hypertension (ISH-IDH) (SBP ≥140 and DBP <90 or SBP <140 and DBP ≥90mmHg), and systolic-diastolic hypertension (SDH) (SBP ≥140 and DBP ≥90mmHg).During the follow-up, the incidence of heart failure (HF), CVD, and coronary heart disease were all lowest for those with optimal-normal BP. Participants with high-normal BP showed greater wall thickness and left ventricular mass index, larger LV size and larger left atrial size when compared with the optimal-normal BP group. Furthermore, those with high-normal BP, ISH-IDH, and SDH had a higher risk of CVD than those with optimal-normal BP. The adjusted relative risk of CVD was highest for SDH (hazard ratio [HR] 1.95; 95% confidence interval [95% CI] 1.37-2.79), followed by ISH-IDH (HR 1.34; 95% CI 0.93-1.95) and high-normal BP (HR 1.31; 95% CI 0.91-1.89).Over a 21-year follow-up, the participants with high-normal BP or ISH-IDH had a higher relative risk of CVD than those with optimal-normal BP.

- Background: Knowledge about long-term risk factors and the prevalence of heart failure stages in general population is limited. We aimed to study the prevalence of cardiac dysfunction and heart failure in 71-year-old men and potential risk factors in the past two decades. Design: This research was based on a randomized selected population study with longitudinal follow-up. Methods: A random sample of men born in 1943 in Gothenburg, Sweden were examined in 1993 (at 50 years of age) and re-examined 21 years later in 2014 (at 71 years of age). Cardiac dysfunction or heart failure was classified into four stages (A-D) according to American Heart Association/American College of Cardiology guidelines on heart failure. Results:Of the 798 men examined in 1993 (overall cohort), 535 (67%) were re-examined in 2014 (echo cohort). In the echo cohort 122 (23%) men had normal cardiac function, 135 (25%) were at stage A, 207 (39%) men were at stage B, 66 (12%) men were at stage C, and five (1%) men were at stage D. Multivariable logistic regression demonstrated that elevated body mass index at 50 years old was the only independent risk factor for developing heart failure/cardiac dysfunction during the subsequent 21 years. For each unit (1 kg/m(2)) of increased body mass index, the odds ratio for stages C/D heart failure vs no heart failure/stage A increased by 1.20 (95% confidence interval, 1.11-1.31, p < 0.001), after adjustment for smoking, sedentary life style, systolic blood pressure, diabetes, and hyperlipidemia. Conclusion: In a random sample of men at 71 years of age, half presented with either cardiac dysfunction or clinical heart failure. High body mass index was associated with an increased risk for developing cardiac dysfunction or heart failure over a 21-year period.

- The population of adults with congenital heart disease (CHD) is growing, and increasingly more patients with CHD reach older ages. Patients with CHD are at an increased risk of myocardial infarction (MI) with increased age. Diagnosing MI in patients with CHD can be challenging in clinical practice owing to a high prevalence of aberrant electrocardiograms, ventricular hypertrophy, and heart failure, among other factors. The National Swedish Patient Register (NPR) is widely used in epidemiological studies; however, MI diagnoses specifically in patients with CHD have never been validated in the NPR.We contacted hospitals and medical archive services to request medical records for 249 patients, born during 1970-2012, with both CHD and MI diagnoses and who were randomly selected from the NPR by the Swedish National Board of Health and Welfare. Follow-up was until 2015. We performed a medical chart review to validate the MI diagnoses; we also validated CHD diagnoses to ensure that only patients with confirmed CHD diagnoses were included in the MI validation process.We received medical records for 96.4% (n=238/249) of patients for validation of CHD diagnoses. In total, 74.8% (n=178/238) had a confirmed CHD diagnosis; of these, 70.2% (n=167) had a fully correct CHD diagnosis in the NPR; a further 4.6% (n=11) had a CHD diagnosis, but it was misclassified. MI diagnoses were validated in 167 (93.8%) patients with confirmed CHD. Of the patients with confirmed CHD, 88.0% (n=147/167) had correct MI diagnoses. Patients with non-complex CHD diagnoses had more correct MI diagnoses than patients with complex CHD (91.0%, n=131 compared with 69.6%, n=16). The main cause for incorrect MI diagnoses was typographical error, contributing to 50.0% of the incorrect diagnoses.The validity of MI diagnoses in patients with confirmed CHD in the NPR is high, with nearly 9 of 10 MI diagnoses being correct (88.0%). MI in patients with CHD can safely be studied using the NPR.

Tidskriftsartikel (refereegranskat)abstract
- Background: Recent published trials have shown the efficacy of transcatheter closure of patent foramen ovale (PFO) for preventing recurrent cryptogenic cerebrovascular events. However, the risk of recurrent cerebrovascular events (rCVEs) is up to 5.7%, and the etiology is unclear. Objective: This study aimed to investigate the risk factors for rCVEs after closure of PFO during long-term follow-up. Methods: In our center, 282 consecutive patients underwent PFO closure because of a cryptogenic cerebrovascular event between 2006 and 2014. Their Risk of Paradoxical Embolism (RoPE) score was calculated retrospectively. We followed up with the patients by telephone, using hospital records to identify those who suffered from rCVEs. Patients with rCVEs were matched with two control patients of the same sex and RoPE score without rCVEs who underwent PFO closure at approximately the same time. The patients with rCVEs and controls participated in a clinical examination, including contrast transthoracic echocardiography (TTE) and Holter electrocardiography, to investigate the possible cause of rCVEs compared with controls. Results: Fourteen (5%) out of the 282 consecutive patients who underwent PFO closure suffered from rCVEs during a mean follow-up of 8.4 years (1.7 rCVEs per 100 patient-years). The median RoPE score of the patients was 7. Recurrent CVE occurred in 3.2 patients per 100 patient-years in patients with residual shunting compared with 0.8 patients per 100 patient-years in those without residual shunt. These patients were on anti-platelet treatment or without any effective anticoagulant treatment at the time rCVE occurred. The risk ratio of rCVEs in patients with residual shunting was 2.9-times higher than in patients without residual shunting (95% CI: 1.4-6.1) at follow-up visit. Four patients who had the BioSTAR device implanted suffered from an rCVE despite lack of residual shunting. Conclusions: This study indicates that residual shunting and choice of the device may be the major reasons for rCVEs.

- Introduction. There is limited knowledge about factors associated with the development of aortic stenosis. This study aimed to examine the prevalence of aortic sclerosis or stenosis in 71-years-old men and determine which risk factors at 50 years of age predict the development of aortic sclerosis or aortic stenosis. Methods. A random sample of Swedish men from the general population, born in 1943 (n = 798) were followed for 21 years. Data on clinical characteristics and laboratory values were collected in 1993. An echocardiography was performed in 2014. We used logistic regression to examine the association between baseline data and the outcome. Results. Echocardiography was performed in 535 men, and aortic sclerosis or aortic stenosis was diagnosed in 27 (5.0%). 14 persons developed aortic stenosis (2.6%). Among men with aortic sclerosis or aortic stenosis, 29.6% were obese. In multivariable stepwise regression model, body mass index (odds ratio per unit increase 1.23 (95% CI 1.10-1.38; p = .0003)) and hypercholesterolemia, combined with high sensitive C-reactive protein (odds ratio versus all other 2.66 (1.18-6.00; p = .019)) were significantly associated with increased risk of developing aortic sclerosis or aortic stenosis. Body mass index was the only factor significantly associated with a higher risk of developing aortic stenosis. Conclusion. The prevalence of either aortic sclerosis or aortic stenosis was 5% and of aortic stenosis 2.6%. Obesity and hypercholesterolemia combined with elevated high sensitive C-reactive protein at the age of 50 predicted the development of degenerative aortic sclerosis or stenosis, whilst only obesity was correlated with the occurrence of aortic stenosis.

- Objectives. There is limited knowledge of atrial fibrillation (AF) incidence among the very old. Data from longitudinal cohort studies may give us a better insight. The aim of the study was to investigate the incidence rate and prevalence of AF, as well as the impact of AF on mortality, in the general population, from 70 to 100 years of age. Design. This was a population-based prospective cohort study where three representative samples of 70-year-old men and women (n = 2,629) from the Gerontological and Geriatric Populations Studies in Gothenburg (H-70) were included between 1971 and 1982. The participants were examined at age 70 years and were re-examined repeatedly until 100 years of age. AF was diagnosed according to a 12-lead electrocardiogram (ECG) recording at baseline and follow-up examinations, from the Swedish National Patient Register (NPR), or from the Cause of Death Register. Results. The cumulative incidence of AF from 70 to 100 years of age was 65.6% for men and 52.8% for women. Mortality was significantly higher in participants with AF compared with those without, rate ratio (RR) 1.92 (95% CI 1.73-2.14). In a subgroup analysis comprising only participants with AF diagnosed by ECG at screening, the RR for death was 1.29 (95% C.I: 1.03-1.63). Conclusions. Among persons surviving to age 70, the cumulative incidence of AF was over 50% during follow-up. Mortality rate was twice as high in participants with AF compared to participants without AF. Among participants with AF first recorded at a screening examination, the increased risk was only 29%.

Tidskriftsartikel (refereegranskat)abstract
- Background Despite advances in pediatric health care over recent decades, it is not clear whether survival in children with congenital heart disease (CHD) is still increasing. Methods and Results We identified all patients with CHD using nationwide Swedish health registries for 1980 to 2017. We examined the survival trends in children with CHD; we investigated the mortality risk in patients with CHD compared with matched controls without CHD from the general population using Cox proportional regression models and Kaplan-Meier survival analysis. Among 64396 patients with CHD and 639012 matched controls without CHD, 3845 (6.0%) and 2235 (0.3%) died, respectively. The mean study follow-up (SD) was 11.4 (6.3) years in patients with CHD. The mortality risk was 17.7 (95% CI, 16.8-18.6) times higher in children with CHD compared with controls. The highest mortality risk was found during the first 4years of life in patients with CHD (hazard ratio [HR], 19.6; 95% CI, 18.5-20.7). When stratified by lesion group, patients with non-conotruncal defects had the highest risk (HR, 97.2; 95% CI, 80.4-117.4). Survival increased substantially according to birth decades, but with no improvement after the turn of the century where survivorship reached 97% in children with CHD born in 2010 to 2017. Conclusions Survival in children with CHD has increased substantially since the 1980s; however, no significant improvement has been observed this century. Currently, >97% of children with CHD can be expected to reach adulthood highlighting the need of life-time management.

- BackgroundA declining trend in mean cholesterol levels and smoking has been observed in high-income western countries during the last few decades, whereas obesity rates have increased. Simultaneously, mortality from coronary heart disease has decreased. The aim of the present study was to determine whether the trends in cardiovascular risk factors have continued in successive cohorts of middle-aged women over a period of 34years.MethodsSix population-based, cross-sectional samples of women (n=2294) mean age: 49.8years (range: 45-54), living in Gothenburg, Sweden, were investigated between 1980 and 2014.ResultsBody mass index (BMI) increased over time, with a mean BMI of 24.7kg/m(2) in 1980 to 25.7kg/m(2) in 2013-2014, corresponding to a weight gain of 4.5kg, together with an increase in the proportion of obese individuals (BMI >= 30kg/m(2)) from 10.4 to 16.6% (p=0.0012). The proportion of smokers and women with hypertension decreased from 34.5 to 12.8% (p=0.0006) and from 37.7 to 24.5% (p<0.0001) respectively. Mean total serum cholesterol levels decreased from 6.23 (SD 1.09) mmol/L in 1980 to 5.43 (SD 0.98) mmol/L in 2013-2014 (p<0.0001). Self-reported leisure time regular exercise increased from 7.8% in 1980 to 35.6% in 2013-2014 (p<0.0001). For women born in 1963, the prevalence ratio of not having any of five major cardiovascular risk factors was 1.82 (95% confidence interval (CI) 1.38-2.41), compared with women born in 1925-1934.ConclusionThe trend towards increasing obesity, more leisure-time physical activity and less smoking remains, while the decrease in serum cholesterol appears to have abated.
