Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Background: Heart failure (HF) is a major health problem worldwide with exponentially increasing incidence with age and the majority of patients being elderly. In recent years, an increase in hospitalization and prevalence of HF in younger persons has been documented in Sweden and Denmark, in contrast to an overall decrease in older patients. In addition, an increase in hospital discharge diagnoses of cardiomyopathy has been reported, also most pronounced among the young. New treatment modalities implemented in every day practice have contributed to improved prognosis in heart failure, but the improvement in mortality has slowed down since the beginning of the 21st century. Aim: The aim of this thesis was 1) to validate hospital diagnoses of cardiomyopathy; 2) to describe characteristics of young patients with HF; 3) to evaluate possible changes in mortality over time by studying mortality rates, mortality risks and estimation of life-years lost compared with matched controls from the general population; and 4) to explore possible sex related differences among young patients with HF. Methods and Results: Through search of local hospital discharge registers at three hospitals in western Sweden 611 medical records from 1989 to 2009 with the diagnoses of cardiomyopathy were validated against the latest ESC diagnostic criteria. Of all cases a high proportion, 86%, filled the criteria current at the time of diagnosis. In Paper II, III and IV several Swedish registers were combined. In Paper II all patients with incident hospitalization for HF registered in the National Patient Register were included. Over two periods, 1987-2002 compared with 2003–1014, a decrease in mortality rates were observed mainly among patients <65 years while in patients ≥65 years only minimal improvement in survival was found. As mortality rates decreased more in matched controls from the general population the relative mortality risk increased in patients <65 years during the observed period. In Paper III and IV, all patients from the Swedish Heart Failure Register were included from 2003 to 2014 and patients <55 years were compared with those ≥55 years and matched controls <55 years with regard to patient characteristics, mortality rates and mortality risk. Patients <55 years had higher rates of concomitant cardiomyopathies, myocarditis, obesity, congenital heart disease and reduced ejection fraction (EF) while older patients had more ischemic heart disease, hypertension and atrial fibrillation. Mortality rates were lower among the patients <55 years but when compared to controls they had five times higher mortality risk and patients 18-34 years of age had up to 38 times higher mortality risk. When compared with the estimated life expectancy of the general population the youngest patients lost up to 26 life-years, this declined with increasing age. Women, compared to men, had higher rates of obesity, congenital heart disease, hypertrophic cardiomyopathy, midrange and preserved EF while men had more ischemic heart disease, atrial fibrillation and more often reduced EF. In absolute numbers there was no difference in mortality rates, but women with HF had almost twice as high mortality risk relative to controls than did men (even though not significant) and lost more life-years than men. The most common cause of death was cardiovascular death (CVD) followed by cancer, presence of the latter was associated with doubled mortality risk in men and a 3-fold increase in risk in women, relative to men and women without concomitant cancer. Conclusion: The validity of the cardiomyopathy diagnoses was high supporting the hypothesis that a real increase of cardiomyopathy might have occurred. Survival of patients with HF improved among patients <65 years while among those older patients the improvement was marginal. The mortality risk relative to age-matched controls increased among the younger group, as the mortality reduction was more pronounced among controls. The younger the patients the higher estimated life-years lost. The most common mode of death was CVD followed by cancer in both sexes. Cancer was associated with increased mortality risk in both sexes.

- 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.

- AIM: Hospital discharges with a diagnosis of cardiomyopathy have more than doubled in Sweden since 1987. We validated the cardiomyopathy diagnoses over this time period to investigate that the increase was real and not a result of improved recognition of the diagnosis and better diagnostic methods. METHODS AND RESULTS: Every fifth year from 1989 to 2009, records for all patients with a cardiomyopathy diagnosis were identified by searching the local registers in three hospitals in Vastra Gotaland, Sweden. The diagnoses were validated according to criteria defined by the European Society of Cardiology from 2008. The population comprised 611 cases with cardiomyopathy diagnoses [mean age 58.9 (SD 15.5) years, 68.2% male], divided into three major groups: dilated, hypertrophic, and other cardiomyopathies. Hypertrophic cardiomyopathy and hypertrophic obstructive cardiomyopathy were analysed as a group. Cardiomyopathies for which there were few cases, such as restrictive, arrhythmogenic right ventricular, left ventricular non-compaction, takotsubo, and peripartum cardiomyopathies, were analysed together and defined as 'other cardiomyopathies'. Relevant co-morbidities were registered. The use of echocardiography was 99.7%, of which 94.6% was complete echocardiography reports. The accuracy rates of the diagnoses dilated cardiomyopathy, hypertrophic cardiomyopathy, and other cardiomyopathies were 85.5%, 87.5%, and 100%, respectively, with no differences between the three hospitals or years studied; nor did the prevalence of co-morbidities differ. CONCLUSIONS: The accuracy rate of the cardiomyopathy diagnoses from in-hospital records from >600 patients in western Sweden during a 20 year period was 86.6%, with no significant trend over time, strengthening epidemiological findings that this is likely due to an actual increase in cardiomyopathy diagnoses rather than changes in coding practices. The use of echocardiography was high, and there was no significant difference in co-morbidities during the study period. The accuracy rate of the cardiomyopathy diagnoses during the 20 year period was high. The use of diagnostic tools did not increase under the study period, and once cardiomyopathy diagnoses were suspected, echocardiography was performed in almost all cases. In this study, the occurrence of cardiomyopathy was increasing over time without significant increase of co-morbidity, supporting that an actual increase of cardiomyopathy has occurred.

- 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.

- 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.

- To determine the incidence of hyperkalaemia in patients with heart failure with reduced ejection fraction (HFrEF) during up-titration of guideline-directed medical therapy (GDMT) in real-world settings.A retrospective review of medical records of all patients hospitalized for newly onset HFrEF at Sahlgrenska University Hospital, Sweden, between 1 January 2016 and 31 December 2019. Based on mineralocorticoid receptor antagonist (MRA) treatment within the first 6months, patients were divided into four groups: (i) never received MRA, (ii) needed MRA dose reduction, (iii) needed discontinuation of MRA, and (iv) stable MRA treatment. Potassium levels were assessed at baseline and has the highest potassium level during the 6months of up-titration.Of 3456 patients hospitalized for heart failure, 630 (18%) were eligible (68.4% men, 66.8years, mean EF of 29.4%). After up-titration of GDMT 48.4% of patients received MRAs. Patients without MRA treatment were older (P<0.0001), had lower EF (P=0.022), had higher NTproBNP (P=0.017), had lower eGFR (P=0.001), and were more often treated with angiotensin receptor inhibitors/angiotensin receptor blockers/angiotensin receptor neprilysin inhibitors (all P<0.0001). In overall study population, hyperkalaemia increased from 5.9 to 24.4% after 6months of up-titration of GDMT (P<0.0001). Among four groups, the incidence of hyperkalaemia throughout up-titration of GDMT increased from 6.8 to 54.5% in patients with dose reduction of MRA, from 8.8 to 50.9% in those with discontinuation of MRA, from 5 to 10% in patients with stable MRA treatment, and from 6 to 28% in patients who were MRA naive (all P<0.0001). In the MRA-naive group, normokalaemia/hypokalaemia occurred in 87.5% at baseline, and after 6months of up-titration of GDMT, normokalaemia/hypokalaemia remained in 47.8%, whereas mild, moderate, and severe hyperkalaemia occurred in 22.4%, 5.7%, and 0.9%, respectively.Hyperkalaemia increased significantly during up-titration of GDMT but with varying magnitudes in different clinical phenotypes, which might explain why physicians refrain from prescribing MRAs to patients with HFrEF.

- Background Peripartum cardiomyopathy (PPCM) is idiopathic pregnancy-associated heart failure (HF) with reduced left ventricular ejection fraction (LVEF). We aimed to assess arterial stiffness and left ventricular (LV) function in women recovered from PPCM compared with controls. Methods Twenty-two PPCM patients were compared with 15 age-matched controls with previous uncomplicated pregnancies. Eleven of the patients were at inclusion in the study recovered and off medication since at least 6 months and still free from cardiovascular symptoms with normal LVEF and normal NT-proBNP. All underwent echocardiography, including LV strain, left atrial (LA) reservoir strain and tissue Doppler early diastolic velocity (e ') and non-invasive assessment for arterial stiffness and central aortic systolic blood pressure (AoBP) at rest and immediately postexercise. Results The patients off medication showed alterations compared with controls. AoBP was higher (120 +/- 9 mm Hg vs. 104 +/- 13 mm Hg; p = .001), a difference which persisted postexercise. The arterial elastance was higher (1.9 +/- 0.4 mm Hg/ml vs. 1.3 +/- 0.2 mm Hg/ml; p < .001), while there were lower e ' septal (8.9 +/- 1.7 cm/s vs. 11.0 +/- 1.1 cm/s; p = 0. 002), LV global strain (18.7 +/- 3.9% vs. 23.1 +/- 1.6%; p = .004) and LA reservoir strain (24.8 +/- 9.1% vs. 37.7 +/- 6.3%; p = .002). Conclusions Compared with healthy controls, PPCM patients considered recovered and off medication had increased arterial stiffness, decreased LV longitudinal function and reduced LA function.

- 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.

- In heart failure (HF) with reduced left ventricular ejection fraction (HFrEF), the prognosis appears better in non-ischaemic than in ischaemic aetiology. Infrequent diagnostic work-up for ischaemic heart disease (IHD) in HF is reported. In this study, we compared short-term response to initiated guideline-directed medical treatment (GDMT) in recent-onset HFrEF of non-ischaemic (non-IHF) vs. ischaemic (IHF) aetiology and evaluated the frequency of coronary investigation.Patients hospitalized with recent-onset HFrEF [left ventricular ejection fraction (LVEF)<40%] between 1 January 2016 and 31 December 2019 were included. Treatment response was determined by use of a hierarchical clinical composite outcome classifying each patient as worsened, improved, or unchanged based on hard outcomes (mortality, heart transplantation, and HF hospitalization) and soft outcomes (±≥10 unit change in LVEF, ±≥30% change in N-terminal pro-B-type natriuretic peptide, and ±≥1 point change in New York Heart Association functional class) during 28weeks of follow-up. The associations between baseline characteristics and composite changes were analysed with multiple logistic regression. Among the 364 patients analysed, 47 were not investigated for IHD. Comparing non-IHF (n=203) vs. IHF (n=114), patients were younger (mean age 61.0 vs. 69.4years, P<0.001) with lower mean LVEF (26% vs. 31%, P<0.001), but with similar male predominance (70.4% vs. 75.4%, P=0.363). For non-IHF vs. IHF, the composite outcomes were worsened (19.1% vs. 43.9%, P<0.001) and improved (74.2% vs. 43.9%, P<0.001). After multivariable adjustments, IHF was associated with increased odds for worsening [odds ratio (OR) 2.94; 95% confidence interval (CI) 1.51-5.74; P=0.002] and decreased odds for improvement (OR 0.35; 95% CI 0.18-0.65; P<0.001). In cases without previous IHD or new-onset myocardial infarction (n=261), a decision for coronary investigation was made in 69.0%.In recent-onset HFrEF, patients with non-IHF responded better to GDMT than patients with IHF. Almost one-third of patients selected for follow-up at HF clinics were never investigated for IHD.
