- Background: Heart failure (HF) in late pregnancy and postpartum (HFPP), of which peripartum cardiomyopathy (PPCM) constitutes the larger part, is still a rare occurrence in Sweden. Population-based data are scarce. Our aim was to characterize HFPP and determine the incidence and mortality in a Swedish cohort. Methods and Results: Through merging data from the National Inpatient, Cause of Death, and Medical Birth Registries, we identified ICD-10 codes for HF and cardiomyopathy within 3 months before delivery to 6 months postpartum. Each case was assigned 5 age -matched control subjects from the Medical Birth Registry. From 1997 to 2010, 241 unique HFPP case subjects and 1063 matched control subjects were identified. Mean incidence was 1 in 5719 deliveries. HFPP was strongly associated with preeclampsia (odds ratio [OR] 11.91, 95% confidence interval [CI] 7.86-18.06), obesity (OR 2.5, 95% CI 1.7-3.7), low-and middle -income country (LMIC) of origin (OR 1.73, 95% CI 1.14-2.63), and twin deliveries (OR 4.39 CI 95% 2.24-8.58). By the end of the study period deaths among cases were > 35 -fold those of controls: 9 cases (3.7 %) and 1 control (0.1 %; P <.0001). Among control subjects, 17.9% of mortalities occurred within 3 years, of diagnosis compared with 100% among cases. Conclusions: The mean incidence and mortality among women with HFPP in Sweden from 1997 to 2010 was low but carried a marked excess risk of death compared with control subjects and was strongly linked to preeclampsia, obesity, multifetal births, and LMIC origin of the mother.

- 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: Differences between the sexes among the non-elderly with heart failure (HF) have been insufficiently evaluated. This study aims to investigate sex-related differences in early-onset HF. Methods: Patients aged 18 to 54 years who were registered from 2003 to 2014 in the Swedish Heart Failure Register were included. Each patient was matched with two controls from the Swedish Total Population Register. Data on comorbidities and outcomes were obtained through the National Patient Register and Cause of Death Register. Results: We identified 3752 patients and 7425 controls. Of the patients, 971 (25.9%) were women and 2781 (74.1%) were men with a mean (standard deviation) age of 44.9 (8.4) and 46.4 (7.3) years, respectively. Men had more hypertension and ischemic heart disease, whereas women had more congenital heart disease and obesity. During the median follow-up of 4.87 years, 26.5 and 24.7 per 1000 person-years male and female patients died, compared with 3.61 and 2.01 per 1000 person-years male and female controls, respectively. The adjusted hazard ratios for all-cause mortality, compared with controls, were 4.77 (3.78-6.01) in men and 7.84 (4.85-12.7) in women (p for sex difference = 0.11). When HF was diagnosed at 30, 35, 40, and 45 years, women and men lost up to 24.6 and 24.2, 24.4 and 20.9, 20.5 and 18.3, and 20.7 and 16.5 years of life, respectively. Conclusion: Long-term mortality was similar between the sexes. Women lost more years of life than men.

- Aims The prevalence and hospitalizations of patients with heart failure (HF) aged <55 years have increased in Sweden during the last decades. We aimed to compare characteristics of younger and older patients with HF, and examine survival in patients All patients >= 18 years in the Swedish Heart Failure Register from 2003 to 2014 were included. Data were merged with National Patient and Cause of Death Registers. Among 60 962 patients, 3752 (6.2%) were <55 years, and were compared with 7425 controls from the Population Register. Compared with patients >= 55 years, patients <55 years more frequently had registered diagnoses of obesity, dilated cardiomyopathy, congenital heart disease, and an ejection fraction <40% (9.8% vs. 4.7%, 27.2% vs. 5.5%, 3.7% vs. 0.8%, 67.9% vs. 45.1%, respectively; allP < 0.001). One-year all-cause mortality was 21.2%, 4.2%, and 0.3% in patients >= 55 years, patients <55 years, and controls <55 years, respectively (allP < 0.001). Patients <55 years had a five times higher mortality risk compared with controls [hazard ratio (HR) 5.48, 95% confidence interval (CI) 4.45-6.74]; the highest HR was in patients 18-34 years (HR 38.3, 95% CI 8.70-169; bothP < 0.001). At the age of 20, the estimated life-years lost was up to 36 years for 50% of patients, with declining estimates with increasing age. Conclusion Patients with HF <55 years had different comorbidities than patients >= 55 years. The highest mortality risk relative to that of controls was among the youngest patients.

Tidskriftsartikel (refereegranskat)abstract
- Pre-eclampsia complicates 3-5% of pregnancies worldwide and is associated with adverse outcomes for the mother and the offspring. Pre-eclampsia and heart failure have common risk factors, including hypertension, obesity and diabetes. It is not known whether heart failure increases the risk of pre-eclampsia. This study examines whether pregestational heart failure increases the risk of pre-eclampsia.In a registry-based case-cohort study that included all pregnancies in Sweden (n=3 125 527) between 1990 and 2019, all pregnancies with pre-eclampsia (n=90 354) were identified and up to five control pregnancies (n=451466) for each case were chosen, matched on the mother's birth year. Multiple logistic regression analysis was used to evaluate the impact of heart failure on the risk of pre-eclampsia, with adjustment for established risk factors and other cardiovascular diseases.Women with heart failure had no increased risk for pre-eclampsia, OR 1.02 (95% CI 0.69 to 1.50). Women with valvular heart disease had an increased OR of preterm pre-eclampsia, with an adjusted OR of 1.78 (95% CI 1.04 to 3.06). Hypertension and diabetes were independent risk factors for pre-eclampsia. Obesity, multifetal pregnancies, in vitro fertilisation, older age, Nordic origin and nulliparity were more common among women who developed pre-eclampsia compared with controls.Women with heart failure do not have an increased risk of pre-eclampsia. However, women with valvular heart disease prior to pregnancy have an increased risk of developing preterm pre-eclampsia independent of other known risk factors.

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

Tidskriftsartikel (refereegranskat)abstract
- Aims To compare trends in short-term and long-term survival of patients with heart failure (HF) compared with controls from the general population. Methods and results We used data from the Swedish National Inpatient Registry to identify all patients aged >= 18 years with a first recorded diagnosis of HF between 1 January 1987 and 31 December 2014 and compared them with controls matched on age and sex from the Total Population Register. We included 702 485 patients with HF and 1 306 183 controls. In patients with HF aged 18-64 years, short-term (29 days to 6 months) and long-term mortality (>11 years) decreased from 166 and 76.6 per 1000 person-years in 1987 to 2000 to 99.6 and 49.4 per 1000 person-years, respectively, in 2001 to 2014. During the same period, mortality improved marginally, in those aged >= 65 years: short-time mortality from 368.8 to 326.2 per 1000 person-years and long-term mortality from 219.6 to 193.9 per 1000 person-years. In 1987-2000, patients aged <65 years had more than three times higher risk of dying at 29 days to 6 months, with an hazard ratio (HR) of 3.66 [95% confidence interval (CI) 3.46-3.87], compared with controls (P < 0.0001) but substantially higher in 2001-2014 with an HR of 11.3 (95% CI 9.99-12.7, P < 0.0001). HRs for long-term mortality (6-10 and >11 years) increased moderately from 2.49 (95% CI 2.41-2.57) and 3.16 (95% CI 3.07-3.24) in 1987-2000 to 4.35 (95% CI 4.09-4.63) and 4.11 (95% CI 3.49-4.85) in 2001-2014, largely because survival among controls improved more than that among patients with HF (P < 0.0001). Conclusions Absolute survival improved in HF patients aged <65 years, but only marginally so in those aged >= 65 years. Compared with controls, both short-term and long-term relative risk of dying increased, especially in younger patients with HF.

Tidskriftsartikel (refereegranskat)abstract
- BackgroundExcess mortality in gout has been attributed to cardiovascular diseases (CVD). Considering the decline in CVD mortality in the general population, we wanted to evaluate overall mortality in gout and cause-specific contributions to mortality beyond CVD and temporal trends. MethodsAll incident cases of gout between 2006 and 2015 in western Sweden and 5 population controls per case matched for age, sex, and county were identified. Comorbidities were identified for 5 years preceding the index date. Follow-up ended at death, migration, or end of study on December 2017. Effect of gout on death risk was calculated using COX regression on the whole population and stratified by sex, adjusted for demographics, and comorbidities. Death incidence rates were compared between the two time periods, 2006-2010 and 2011-2015. ResultsWe identified 22,055 cases of incident gout and 98,946 controls, median age (Q1, Q3) 69-68 (57, 79/56, 78) years and 67.6-66.5% males. Except for dementia, all comorbidities were significantly more common at baseline among gout cases. Overall, the risk for death in incident gout was neither increased overall nor in men, but women had a 10% elevated risk. In adjusted models for cause-specific mortality, death from CVD, renal disease, and digestive system diseases were significantly increased in the total gout population while death from dementia, cancer, and lung diseases were significantly decreased. There were no significant differences in overall incident death rate ratios between cases and controls in the two time periods examined. ConclusionsAn increased risk for CVD, renal disease, and diseases of the digestive system in patients with gout highlights the importance of addressing CVD risk factors in gout management. Gout was associated with reduced mortality from dementia, which may have implications on urate lowering therapy and possible effects on dementia risk.

- Investigate trends in myocarditis incidence and prognosis in Sweden during 2000-2014. Little data exist concerning population-trends in incidence of hospitalizations for myocarditis and subsequent prognosis. Linking Swedish National Patient and Cause of Death Registers, we identified individuals≥16years with first-time diagnosis of myocarditis during 2000-2014. Reference population, matched for age and birth year (n=16,622) was selected from Swedish Total Population Register. Among the 8 679 cases (75% men, 64%<50years), incidence rate/100,000 inhabitants rose from 6.3 to 8.6 per 100,000, mostly in men and those<50years. Incident heart failure/dilated cardiomyopathy occurred in 6.2% within 1year after index hospitalization and in 10.2% during 2000-2014, predominantly in those≥50years (12.1% within 1year, 20.8% during 2000-2014). In all 8.1% died within 1year, 0.9% (<50years) and 20.8% (≥50years). Hazard ratios (adjusted for age, sex) for 1-year mortality comparing cases and controls were 4.00 (95% confidence interval 1.37-11.70), 4.48 (2.57-7.82), 4.57 (3.31-6.31) and 3.93 (3.39-4.57) for individuals aged<30, 30 to<50, 50 to<70, and≥70years, respectively. The incidence of myocarditis during 2000-2014 increased, predominantly in men<50years. One-year mortality was low, but fourfold higher compared with reference population.

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