Tidskriftsartikel (refereegranskat)abstract
- Background Improvements in diagnosis, intervention, and care of congenital heart disease (CHD) have led to increased survivability and lifelong dependence on healthcare. This study aims to determine the extensiveness of inpatient care episodes across different life-stages and CHD severity compared to matched controls, and to explore how healthcare utilization among pediatric CHD cases have changed over time. Methodology National registry data was used to conduct a 1:9 matching analysis with age and sex matched controls. Then, Poisson timeseries analysis was used to conduct trend analysis for inpatient healthcare utilization among pediatric cases <18 years of age. Results Most CHD cases were non-complex (87.3%), with highest hospitalization rates occurring in infancy. Mean number of hospitalizations among complex cases were over twice that of non-complex cases. Also, as age progressed, mean hospitalization for non-complex cases began converging to the control population. In terms of trend analysis within this study period, healthcare utilization increased by 34% among the infant categories, but decreased by 12% and 32% among children between 1-9 years and 10–17 years, respectively. Also, utilization was not trending in one direction substantiating the claim that multiple time periods are required to assess temporal changes within this population. Conclusion Inpatient healthcare utilization among the CHD population appears to be decreasing over time in most cases, where non-complex cases transitioning to adult care are increasingly converging to the general population. Additionally, this study validates the need to use multiple time-periods when conducting longitudinal studies across the CHD population.

Anticoagulation treatment in adult patients with congenital heart defects and bleeding-related mortality
- 2023
-
Ingår i: Progress in Pediatric Cardiology. - : Elsevier BV. - 1058-9813. ; 68

Tidskriftsartikel (refereegranskat)abstract
- Background: Congenital heart disease (CHD) is the most common type of birth defect. Survival, especially for patients with complex heart defects, has increased dramatically and today 97 % of those born with heart defects reach adulthood. As a late effect of both the congenital malformations and various types of interventions, these patients generally have an increased risk of atrial fibrillation, which is strongly associated with stroke. Additionally, implantation of foreign materials such as mechanical heart valves is also associated with higher risk for embolization. Therefore, adult patient with congenital heart disease (ACHD) are at a substantially increased risk of thromboembolism which necessitates anticoagulant therapy. However, the impact and risk of bleeding and bleeding-related mortality, particularly in young ACHD patients, during long-term anticoagulation treatment is unclear. Methods: In this retrospective cohort study, 117 deceased ACHD patients with anticoagulant treatment were identified by using the Swedish registry of congenital heart disease between 2005 and 2021. Data from medical records were collected and analyzed. Variables obtained were main diagnosis, indication and type of anticoagulation treatment, complications, and cause of death. Results: A total of 17 ACHD patients (14.5 %) experienced bleeding events. Ten ACHD patients (8.5 %) experienced major bleeding, including five patients (4.3 %) who died of a hemorrhagic stroke. Another seven ACHD patients had minor bleeding (6 %). Conclusion: Despite the occurrence of bleeding-related complications, the proportion of serious, fatal bleeding was low among deceased ACHD patients with anticoagulation treatment.

Risk factors for and risk of all-cause and atherosclerotic cardiovascular disease mortality in people with type 2 diabetes and peripheral artery disease: an observational, register-based cohort study
- 2024

Tidskriftsartikel (refereegranskat)abstract
- Background Type 2 diabetes (T2D) and peripheral artery disease (PAD) are recognized as independent risk factors contributing to excess mortality. Contemporary observational studies exploring the associations of risk factors, and risk of all-cause and atherosclerotic cardiovascular disease mortality in persons with T2D following the onset of incident peripheral artery disease are limited. The objectives of this study were to investigate the associations of risk factors, and assess mortality risks in people with T2D compared with controls without T2D after the onset of PAD. Methods All persons with T2D (n = 150,215) registered in the Swedish National Diabetes Register between 2005 and 2009 were included, along with 346,423 controls without T2D matched for sex and age. Data were retrieved from several national registries, capturing information on risk factors, onset of incident peripheral artery disease, other comorbidities, socioeconomic factors, and outcomes. To compare persons with T2D and controls following the onset of peripheral artery disease regarding the risk of all-cause, and atherosclerotic cardiovascular disease mortality, Cox proportional hazard models and Kaplan-Meier curves were employed. A gradient-boosting model was utilized to estimate the relative statistical contribution of risk factors to the modeling of incident mortality risk in people with both T2D and peripheral artery disease. Results Crude rates of incident all-cause mortality were higher in individuals with T2D compared with controls, following the onset of PAD (600.4 (95% CI, 581.4-619.8) per 10,000 person-years versus 549.1 (95% CI, 532.1-566.5) per 10,000 person-years). Persons with T2D had an adjusted hazard ratio (HR) for all-cause mortality of 1.12 (95% CI, 1.05-1.19, P < 0.01) compared with controls after onset of incident PAD. The comparable adjusted HR for cardiovascular mortality was 1.13 (95% CI, 1.07-1.19, P < 0.01). High age and hyperglycemia at baseline played a significant role in contributing to the predictive models for incident all-cause and cardiovascular mortality among individuals with both T2D and PAD. Conclusions The presence of T2D with concomitant PAD is related to an increased risk of both all-cause and cardiovascular mortality compared with individuals with only PAD. This argues for implementing optimized and intensive treatment strategies for individuals with both conditions.

- To investigate to what extent having control of peripheral artery disease (PAD) risk factors is associated with the risk of incident PAD in individuals with type 2 diabetes.A total of 148,096 individuals with type 2 diabetes in the Swedish National Diabetes Register between 2005 and 2009 were included and matched with 320,066 control subjects on the basis of age, sex, and county. A few control subjects who developed type 2 diabetes after recruitment, during wash-in (<0.2%), were not censored but instead matched with two new control subjects. Individuals with type 2 diabetes were evaluated according to the number of PAD risk factors beyond recommended guideline levels at baseline, including LDL cholesterol, blood pressure, smoking, glycated hemoglobin, and estimated glomerular filtration rate. Incident PAD events were ascertained from 2006 to 2019.A graded association was observed between the number of PAD risk factors not at target and incident PAD in individuals with type 2 diabetes. The adjusted hazard ratio for PAD was 1.41 (95% CI 1.23-1.63) for those with type 2 diabetes with all PAD risk factors within target compared with control subjects matched for sex, age, and county but not risk factor status, in contrast with 9.28 (95% CI 3.62-23.79) for those with all five PAD risk factors not at target.A graded association was observed between increasing number of PAD risk factors not at target and incident PAD in individuals with type 2 diabetes.

- Background Body iron stores (BISs) have been proposed to be related to the development of cardiovascular diseases. However, results from epidemiological studies are conflicting. Knowledge on the long-term impact of BIS on cardiovascular outcomes in the general population is lacking. Purpose The aim of this study was to explore the relationship between BIS and coronary heart disease (CHD) including death due to CHD. Methods This investigation is part of 'The Study of Men Born in 1943', a longitudinal prospective study of men living in the city of Gothenburg, Sweden. This random population sample was examined in 1993 (all at 50 years of age at baseline). A medical examination was performed, and questionnaires were used to evaluate lifestyle factors. Biomarkers for iron stores (serum ferritin and serum transferrin receptor) was analysed from frozen blood samples in 2014. All hospital admissions were registered through national registers during the entire follow-up from 1993 to 2014. HRs were estimated by Cox proportional-hazard regression analyses. Results During the 21 years follow-up period, 120 participants (15.2%) developed CHD and 16 patients (2%) died due to CHD. The all-cause mortality was 15.2% (n=120) including 40 cardiovascular deaths (5.1%). In a multivariable Cox regression analysis, the daily smoking, hypertension and the increased resting heart rate was independent predictors of CHD, while no significant association was found between BIS and risk of CHD. Conclusions In a cohort of middle-aged men from the general population with well validated and prospectively collected data, we did not find any association between serum ferritin or serum transferrin receptor as markers of BIS and CHD events after 21 years of follow-up.

Tidskriftsartikel (refereegranskat)abstract
- Reduced left ventricular ejection fraction (LVEF) is associated with increased mortality after acute myocardial infarction (AMI). However, the prognostic impact of elevated systolic pulmonary artery pressure (sPAP) in the very elderly patients after AMI is lacking. We aimed to study the impact of elevated sPAP on one- and five-year all-cause mortality after AMI in very elderly patients, 80 years of age and older. Of a total number of 353 patients (>= 80 years) who were hospitalized with acute coronary syndrome, 162 patients presenting with AMI and with available data of sPAP on echocardiography were included and followed-up for 5 years. The survival analyses were performed using Cox-Regression models adjusted for conventional risk factors including LVEF. Altogether 66 of 162 patients (41%) had ST-segment elevation MI, and 121 (75%) of patients were treated with percutaneous coronary intervention in the acute phase. Echocardiography during the admission revealed that 78 patients (48%) had a LVEF <= 45% and 66 patients (41%) had a sPAP >= 40 mmHg. After one and five years of follow-up, 23% (n = 33) and 53% (n = 86) of patients died, respectively. A multivariable Cox-Regression analysis showed that the elevated sPAP (>= 40 mmHg) was an independent predictor of increased mortality in both one and five years after AMI; HR of 2.63 (95%, CI 1.19-5.84, P 0.017) and HR of 2.08 (95%, CI 1.25-3.44, P 0.005) respectively, whereas LVEF <= 45% did not show any statistically significant impact, neither on one- nor on five-year mortality (HR 1.3, 95% CI 0.6-2.9, p = 0.469) and (HR 1.4, 95% CI 0.8-2.4, p = 0.158), respectively. Elevated sPAP was an independent risk factor for one- and five-year all-cause mortality after AMI in very elderly patients and sPAP seems to be a better prognostic predictor for all-cause mortality than LVEF. The risk of all-cause mortality after AMI increased with increasing sPAP.

Tidskriftsartikel (refereegranskat)abstract
- AimsKnowledge of long-term outcomes in patients with atrial fibrillation (AF) remains limited. We sought to evaluate the risk of new-onset heart failure (HF) in patients with AF and a low cardiovascular risk profile. Methods and resultsData from the Swedish National Patient Register were used to identify all patients with a first-time diagnosis of AF without underlying cardiovascular disease at baseline between 1987 and 2018. Each patient was compared with two controls without AF from the National Total Population Register. In total, 227 811 patients and 452 712 controls were included. During a mean follow-up of 9.1 (standard deviation 7.0) years, the hazard ratio (HR) for new-onset HF was 3.55 [95% confidence interval (CI) 3.51-3.60] in patients compared with controls. Women with AF (18-34 years) had HR for HF onset 24.6 (95% CI 7.59-80.0) and men HR 9.86 (95% CI 6.81-14.27). The highest risk was within 1 year in patients 18-34 years, HR 103.9 (95% CI 46.3-233.1). The incidence rate within 1 year increased from 6.2 (95% CI 4.5-8.6) per 1000 person-years in young patients (18-34 years) to 142.8 (95% CI 139.4-146.3) per 1000 person-years among older patients (>80 years). ConclusionsPatients studied had a three-fold higher risk of developing HF compared with controls. Young patients, particularly women, carry up to 100-fold increased risk to develop HF within 1 year after AF. Further studies in patients with AF and low cardiovascular risk profile are needed to prevent serious complications such as HF.

- Background: We studied the association between cardiorenal function and survival, neurological outcome and trends in survival after in-hospital Methods: We included cases aged 18 years in the Swedish Cardiopulmonary Resuscitation Registry during 2008 to 2020. The CKD-EPI equation was used to calculate estimated glomerular filtration rate (eGFR). A history of heart failure was defined according to contemporary guideline criteria. Logistic regression was used to study survival. Neurological outcome was assessed using cerebral performance category (CPC). Results: We studied 22,819 patients with IHCA. The 30-day survival was 19.3%, 16.6%, 22.5%, 28.8%, 39.3%, 44.8% and 38.4% in cases with eGFR < 15, 15-29, 30-44, 45-59, 60-89, 90-130 and 130-150 ml/min/1.73 m2, respectively. All eGFR levels below and above 90 ml/min/1.73 m2 were associated with increased mortality. Probability of survival at 30 days was 62% lower in cases with eGFR < 15 ml/min/1.73 m2, compared with normal kidney function. At every level of eGFR, presence of heart failure increased mortality markedly; patients without heart failure displayed higher mortality only at eGFR below 30 ml/min/1.73 m2. Among survivors with eGFR < 15 ml/min/1.73 m2, good neurological outcome was noted in 87.2%. Survival increased in most groups over time, but most for those with eGFR < 15 ml/min/1.73 m2, and least for those with normal eGFR. Conclusions: All eGFR levels below and above normal range are associated with increased mortality and this association is modified by the presence of heart failure. Neurological outcome is good in the majority of cases, across kidney function levels and survival is increasing.

- Background: Worldwide, 1-2% of children are born with congenital heart disease (CHD) with 97% reaching adulthood. Objectives: This study aims to demonstrate the risk of diabetes in patients with CHD, and the influence of incident diabetes on mortality in CHD patients and controls. Methods: By combining data from patient registries, the incidence of adult -onset diabetes registered at age 35 or older, and subsequent mortality risk were analysed in two successive birth cohorts (born in 1930-1959 and 1960-1983), by type of CHD lesion and sex, compared with population -based controls matched for sex and year of birth and followed until a maximum of 87 years of age. Results: Out of 24,699 patients with CHD and 270,961 controls, 8.4% and 5.6%, respectively, were registered with a diagnosis of diabetes at the age of 35 or older, hazard ratio (HR) 1.47 (95% CI 1.40-1.54). The risk of diabetes was higher in the second birth cohort (HR of 1.74, 95% CI 1.54-1.95) and increased with complexity of CHD. After onset of DM, the total mortality among patients with CHD was 475 compared to 411/ 10,000 personyears among controls (HR 1.16, 95% CI 1.07-1.25). Conclusions: In this nationwide cohort of patients with CHD and controls, the incidence of diabetes was almost 50% higher in patients with CHD, with higher risk in the most recent birth cohort and in those with conotruncal defects, with the combination of CHD and diabetes associated with a significantly increased mortality compared to diabetic controls.

- 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.

- Background Resting heart rate (RHR), a known cardiovascular risk factor, changes with age. However, little is known about the association between changes in RHR and the risk of cardiovascular events. The purpose of this study was therefore to assess the impact of RHR at baseline, and the change in RHR over time, on the risk of all-cause death and cardiovascular events. Design A random population sample of men born in 1943 who were living in Gothenburg, Sweden was prospectively followed for a 21-year period. Methods Participants were examined three times: first in 1993 and then re-examined in 2003 and 2014. At each visit, a clinical examination, an ECG and laboratory analyses were performed. Change in RHR between 1993 and 2003 was defined as a decrease if RHR decreased by 5 beats per minute (bpm), an increase if RHR increased by 5 bpm or stable if the RHR change was <4bpm). Results Participants with a baseline RHR of >75 bpm in 1993 had about a twofold higher risk of all-cause death (HR 2.3, CI 1.2 to 4.7, p=0.018), cardiovascular disease (CVD) (HR 1.8, CI 1.1 to 3.0, p=0.014) and coronary heart disease (CHD) (HR 2.2, CI 1.1 to 4.5, p=0.025) compared with those with <55 bpm in 1993. Participants with a stable RHR between 1993 and 2003 had a 44% decreased risk of CVD (HR 0.56, CI 0.35 to 0.87, p=0.011) compared with participants with an increasing RHR. Furthermore, every beat increase in heart rate from 1993 was associated with a 3% higher risk for all-cause death, 1% higher risk for CVD and 2% higher risk for CHD. Conclusion High RHR was associated with an increased risk of death and cardiovascular events in men from the general population. Moreover, individuals with an increase in RHR between 50 and 60 years of age had worse outcome. © Author(s) (or their employer(s)) 2019. Re-use permitted under CC BY-NC. No commercial re-use.

- The QRS complex has been shown to be a prognostic marker in coronary artery disease. However, the changes in QRS duration over time, and its predictive value for cardiovascular disease in the general population is poorly studied. So we aimed to explore if increased QRS duration from the age of 50-60 is associated with increased risk of major cardiovascular events during a further follow-up to age 71. A random population sample of 798 men born in 1943 were examined in 1993 at 50 years of age, and re-examined in 2003 at age 60 and 2014 at age 71. Participants who developed cardiovascular disease before the re-examination in 2003 (n = 86) or missing value of QRS duration in 2003 (n = 127) were excluded. Delta QRS was defined as increase in QRS duration from age 50 to 60. Participants were divided into three groups: group 1: Delta QRS < 4 ms, group 2: 4 ms <= Delta QRS < 8 ms, group 3: Delta QRS >= 8 ms. Endpoints were major cardiovascular events. And we found compared with men in group 1 (Delta QRS < 4 ms), men with Delta QRS >= 8 ms had a 56% increased risk of MACE during follow-up to 71 years of age after adjusted for BMI, systolic blood pressure, smoking, hyperlipidemia, diabetes and heart rate in a multivariable Cox regression analysis (HR 1.56, 95% CI:1.07-2.27, P = 0.022). In conclusion, in this longitudinal follow-up over a decade QRS duration increased in almost two out of three men between age 50 and 60 and the increased QRS duration in middle age is an independent predictor of major cardiovascular events.

- BackgroundA high resting heart rate (RHR) is associated with an increase in adverse events. However, the long-term prognostic value in a general population is unclear. We aimed to investigate the impact of RHR, based on both baseline and time-updated values, on mortality in a middle-aged male cohort.MethodsA random population sample of 852 men, all born in 1913, was followed from age 50 until age 98, with repeated examinations including RHR over a period of 48 years. The impact of baseline and time-updated RHR on cause-specific mortality was assessed using Cox proportional hazard models and cubic spline models.ResultsA baseline RHR of ≥ 90 beats per minute (bpm) was associated with higher all-cause mortality, as compared with an RHR of 60–70 bpm (hazard ratio [HR] 1.60, 95% confidence interval [CI] 1.17–2.19, P = 0.003), but not with cardiovascular (CV) mortality. A time-updated RHR of < 60 bpm (HR 1.41, 95% CI 1.07–1.85, P = 0.014) and a time-updated RHR of 70–80 bpm (HR 1.34, 95% CI 1.02–1.75, P = 0.036) were both associated with higher CV mortality as compared with an RHR of 60–70 bpm after multivariable adjustment. Analyses using cubic spline models confirmed that the association of time-updated RHR with all-cause and CV mortality complied with a U-shaped curve with 60 bpm as a reference.ConclusionIn this middle-aged male cohort, a time-updated RHR of 60–70 bpm was associated with the lowest CV mortality, suggesting that a time-updated RHR could be a useful long-term prognostic index in the general population.

- Background:The survival of children with congenital heart disease has increased substantially over the past decades, with 97% currently reaching adulthood. The total effect of advanced treatment on future mortality and morbidity in adult survivors with congenital heart disease (CHD) is less well described. Methods:We used data from the Swedish National Inpatient, Outpatient, and Cause of Death Register to identify patients with CHD who were born between 1950 and 1999 and were alive at 18 years of age. Ten controls identified from the Total Population Register were matched for year of birth and sex and with each patient with CHD. Follow-up was from 1968 and 18 years of age until death or at the end of the study (2017). Survival percentage with 95% CI for all-cause mortality were performed with Kaplan-Meier survival function. Cox proportional hazard regression models with hazard ratios (HRs) and 95% CI were used to estimate the risk of all-cause mortality. Results:We included 37 278 patients with adult CHD (ACHD) and 412 799 controls. Mean follow-up was 19.2 years (+/- 13.6). Altogether, 1937 patients with ACHD (5.2%) and 6690 controls (1.6%) died, a death rate of 2.73 per 1000 person-years and 0.84 per 1000 person years, respectively. Mortality was 3.2 times higher (95% CI, 3.0-3.4; P<0.001) among patients with ACHD compared with matched controls. Up to the maximum of 50 years of follow-up, >75% of patients with ACHD were still alive. Mortality was highest among patients with conotruncal defects (HR, 10.13 [95% CI, 8.78-11.69]), but also significantly higher for the more benign lesions, with the lowest risk in patients with atrial septal defects (HR, 1.36 [95% CI, 1.19-1.55]). At least 75% of patients with ACHD alive at 18 years of age lived past middle age and became sexagenerians. Conclusions:In this large, nationwide, register-based cohort study of patients with ACHD surviving to 18 years of age, the risk of mortality up to 68 years of age was >3 times higher compared with matched controls without ACHD. Despite this, at least 75% of patients with CHD alive at 18 years of age lived past middle age and became sexagenerians. A notable risk decline in the mortality for patients with ACHD was seen for those born after 1975.

- Aims The aim of this study was to investigate the relation between body mass index (BMI) in young women, using weight early in pregnancy as a proxy for pre-pregnancy weight, and risk for early cardiovascular disease (CVD) and mortality. Methods and results In this prospective, registry-based study, we used weight data in early pregnancy from women, registered in the Swedish Medical Birth Registry, and who gave birth between 1982 and 2014 (n = 1,495,499; median age 28.3 years). Of the women, 118,212 (7.9%) were obese (BMI >= 30 kg/m(2)) and 29,630 (2.0%) severely obese (BMI >= 35 kg/m(2)). After a follow-up of median 16.3 years, we identified 3295 and 4375 cases of acute myocardial infarction (AMI) and ischemic stroke (IS) corresponding to 13.4 and 17.8 per 100,000 observation years, respectively, occurring at mean ages of 49.8 and 47.3 years. Compared to women with a BMI 20-<22.5 kg/m(2), the hazard ratio (HR) of AMI increased with higher BMI from 1.40 (95% confidence interval (CI) 1.27-1.54) among women with BMI 22.5-<25.0 kg/m(2) to 4.71 (95% CI 3.88-5.72) among women with severe obesity, with similar findings for IS and CVD death, after adjustment for age, pregnancy year, parity and comorbidities at baseline. Women with BMI 30-<35.0 and >= 35 kg/m(2) had increased all-cause mortality with adjusted HR 1.53 (95% CI 1.43-1.63) and 1.83 (95% CI 1.63-2.05), respectively. Conclusion A significant increase in the risk for early AMI, IS and CVD death was noticeable in overweight young women, with a marked increase in obese women.

- Survival rates for unoperated patients with Ebstein's anomaly (EA) are unknown. We estimated overall long-term mortality in operated and unoperated EA patients, compared with the general population in Sweden.Using national medical registries, Swedish individuals born 1970-1993 and diagnosed with EA between 1970 and 2011 were included. The hazard ratio for overall mortality for EA patients (n=216) vs. the matched comparison cohort (n=2160) was 43.7 (95% confidence interval (CI): 24.8-82.5). Mortality risk for EA patients (vs. controls) decreased as birth period progressed, with hazard ratios declining from 63.6 (95% CI: 26.3-191.8) for those born in the 1970s to 34.4 (95% CI: 15.8-83.1) for those born in the 1980s and 20.2 (95% CI: 1.6-632.5) for those born at the beginning of 1990s. The overall mortality hazard ratios for unoperated and operated patients with EA (vs. controls) were 30.2 (95% CI: 13.8-73.3) and 63.7 (95% CI: 28.1-172.5), respectively. The risk of mortality among unoperated EA patients (vs. controls) declined with progressing birth period, with hazard ratios declining from 58.4(95% CI: 15.1-415.2) in the 1970s to 22.9(95% CI: 8.0-75.3) in the 1980s and 0 (95% CI:0.0-70.2) in the 1990s.Overall all-cause mortality for patients with EA declined dramatically from 64 times to 20 times that of controls without EA, from the 1970s to the early 1990s. Unoperated patients with EA had better survival than did operated patients, possibly reflecting the higher severity of disease or more severe associated cardiac defects in patients undergoing surgery.

- BACKGROUND Low birth prevalence and referral bias constitute significant obstacles to elucidating the natural history of Ebstein anomaly (EA).OBJECTIVES An extensive 2-country register-based collaboration was performed to investigate the mortality in patients with EA.METHODS Patients born from 1970 to 2017 and diagnosed with EA were identified in Danish and Swedish nationwide medical registries. Each patient was matched by birth year and sex with 10 control subjects from the general population. Cumulative mortality and HR of mortality were computed using Kaplan-Meier failure function and Cox proportional regression model.RESULTS The study included 530 patients with EA and 5,300 matched control subjects with a median follow-up of 11 years. In the EA cohort, 43% (228) underwent cardiac surgery. Cumulative mortality was lower for patients diagnosed in the modern era (the year 2000 and later) than for those diagnosed in the prior era (P < 0.001). Patients with isolated lesion displayed lower cumulative mortality than patients with complex lesions did (P < 0.001). Patients with a presumed mild EA anatomy displayed a 35-year cumulative mortality of 11% (vs 4% for the matched control subjects; P < 0.001), yielding an HR for mortality of 6.0 (95% CI: 2.7-13.6), whereas patients with presumed severe EA demonstrated an HR of 36.2 (95% CI: 15.5-84.4) compared with control subjects and a cumulative mortality of 18% 35 years following diagnosis. CONCLUSIONS Mortality in patients with EA is high irrespective of presence of concomitant congenital cardiac malformations and time of diagnosis compared with the general population, but overall mortality has improved in the contemporary era.
