Journal article (peer-reviewed)abstract
- Persons with chronic heart failure should be recommended aerobic and resistance exercise to be able to increase maximal oxygen uptake (VO2 max), walking distance, and health related quality of life (moderately strong scientific evidence - quality of evidence +++), and to reduce mortality and hospital admissions and increase muscle strength and endurance (low scientific evidence - quality of evidence ++). Prescription of exercise in chronic heart failure should always be preceded of assessments of aerobic and muscular fitness. The aerobic exercise could be conducted as continuous or interval exercise. In connection with ongoing exercise special attention is needed regarding heart rate, diverging blood pressure reactions, contingent occurrence of arrhythmias and the advent of symptoms such as dizziness and severe dyspnea.

- Aims To investigate the association between cardiorespiratory fitness (CRF) and muscle strength in late adolescence and the long-term risk of heart failure (HF). Methods A cohort was created of Swedish men enrolled in compulsory military service between 1968 and 2005 with measurements for CRF and muscle strength ( n=1,226,623; mean age 18.3 years). They were followed until 31 December 2014 for HF hospitalization as recorded in the Swedish national inpatient registry. Results During the follow-up period (median (interquartile range) 28.4 (22.0-37.0) years), 7656 cases of first HF hospitalization were observed (mean±SD age at diagnosis 50.1±7.9 years). CRF and muscle strength were estimated by maximum capacity cycle ergometer testing and strength exercises (knee extension, elbow flexion and hand grip). Inverse dose-response relationships were found between CRF and muscle strength with HF as a primary or contributory diagnosis with an adjusted hazards ratio (95% confidence interval) of 1.60 (1.44-1.77) for low CRF and 1.45 (1.32-1.58) for low muscle strength categories. The associations of incident HF with CRF and muscle strength persisted, regardless of adjustments for the other potential confounders. The highest risk was observed for HF associated with coronary heart disease, diabetes or hypertension. Conclusions In this longitudinal study of young men, we found inverse and mutually independent associations between CRF and muscle strength with risk of hospitalization for HF. If causal, these results may emphasize the importance of the promotion of CRF and muscle strength in younger populations.

- Heart failure (HF) incidence appears to increase among younger individuals, raising questions of how risk factors affect the younger population. We investigated the association of cognitive performance in late adolescence with long-term risk of early HF.We followed a cohort of Swedish men enrolled in mandatory military conscription in 1968-2005 (n=1 225 300; mean age 18.3years) until 2014 for HF hospitalization, using data from the Swedish National Inpatient Registry. Cognitive performance (IQ) was measured through a combination of tests, separately evaluating logical, verbal, visuospatial, and technical abilities. The results were standardized, weighted, and presented as stanines of IQ. The association between IQ and risk of HF was estimated using Cox proportional hazards models. In follow-up, there were 7633 cases of a first HF hospitalization (mean age at diagnosis 50.1years). We found an inverse relationship between global IQ and risk of HF hospitalization. Using the highest IQ stanine as reference, the adjusted hazard ratio for the lowest IQ with risk of HF was 3.11 (95% confidence interval 2.60-3.71), corresponding to a hazard ratio of 1.32 (95% CI 1.28-1.35) per standard deviation decrease of IQ. This association proved persistent across predefined categories of HF with respect to pre-existing or concomitant co-morbidities; it was less apparent among obese conscripts (P for interaction =0.0004).In this study of young men, IQ was strongly associated with increased risk of early HF. The medical profession needs to be aware of this finding so as to not defer diagnosis.

Journal article (peer-reviewed)abstract
- Aim: To investigate the association of resting heart rate (RHR) measured in late adolescence with the long term risk of myocardial infarction (MI), ischemic stroke (IS), heart failure (HF), atrial fibrillation (AF), cardiovascular- and all-cause death. Methods and results: We followed a cohort of Swedish men enrolled for conscription in 1968–2005 (n = 1,008,485; mean age = 18.3 years) until December 2014. Outcomes were collected from the national inpatient - (IPR), outpatient - (OPR) and cause of death registries. Cox proportional hazard models were used to analyze the longitudinal association between RHR and outcomes while adjusting for potential confounders. While we found no independent association between RHR and risk of IS or MI when comparing the highest with the lowest quintile of the RHR distribution, but a positive association persisted between RHR and incident HF (Hazard ratio (HR) = 1.39 [95% confidence interval (CI) = 1.29–1.49]) after adjustment for body mass index (BMI) and blood pressure (BP). In similarly adjusted models, an inverse association was found for AF while there were weaker associations with death from cardiovascular disease (CVD) and all causes (adjusted HR = 1.12 [CI = 1.04–1.21] and 1.20 [CI = 1.17–1.24]). After further adjustment for cardiorespiratory fitness (CRF), the associations persisted for HF (HR = 1.26 [1.17–1.35] for any diagnostic position and HR = 1.43 [1.28–1.60] for HF as a main diagnosis) and for all-cause death (HR 1.09 [1.05–1.12]) but not for CVD death. Conclusion: Adolescent RHR is associated with future risk of HF and death, independently of BP, BMI and CRF, but not with CVD death, MI or IS, suggesting a causal pathway between elevated heart rate and myocardial dysfunction. © 2018 The Authors

Journal article (peer-reviewed)abstract
- Background: Modifiable lifestyle factors in relation to risk for cardiomyopathy, a common and increasing cause of heart failure in the young, have not been widely studied. We sought to investigate a potential link between obesity, a recognized predictor of early heart failure, in adolescence and being diagnosed with cardiomyopathy in adulthood. Methods: This was a nationwide register-based prospective cohort study of 1 668 893 adolescent men (mean age, 18.3 years; SD, 0.7 years) who enlisted for compulsory military service from 1969 to 2005. At baseline, body mass index (BMI), blood pressure, and medical disorders were registered, along with test results for fitness and muscle strength. Cardiomyopathy diagnoses were identified from the National Hospital Register and Cause of Death Register during an up to 46-year follow-up and divided into categories: dilated, hypertrophic, alcohol/drug-induced, and other. Hazard ratios were calculated with Cox proportional hazards models. Results: During follow-up (median, 27 years; Q1-Q3, 19-35 years), 4477 cases of cardiomyopathy were identified, of which 2631 (59%) were dilated, 673 (15%) were hypertrophic, and 480 (11%) were alcohol/drug-induced. Increasing BMI was strongly associated with elevated risk of cardiomyopathy, especially dilated, starting at levels considered normal (BMI, 22.5-<25 kg/m(2); hazard ratio, 1.38 [95% CI, 1.22-1.57]), adjusted for age, year, center, and baseline comorbidities, and with a >8-fold increased risk at BMI >= 35 kg/m(2) compared with BMI of 18.5 to <20 kg/m(2). For each 1-unit increase in BMI, similarly adjusted hazard ratios were 1.15 (95% CI, 1.14-1.17) for dilated cardiomyopathy, 1.09 (95% CI, 1.06-1.12) for hypertrophic cardiomyopathy, and 1.10 (1.06-1.13) for alcohol/drug-induced cardiomyopathy. Conclusions: Even mildly elevated body weight in late adolescence may contribute to being diagnosed with cardiomyopathy in adulthood. The already marked importance of weight control in youth is further strengthened by these findings, as well as greater evidence for obesity as a potential important cause of adverse cardiac remodeling that is independent of clinically evident ischemic heart disease.

- AIMS: To study the relation between body mass index (BMI) in young men and risk of early hospitalization with heart failure. METHODS AND RESULTS: In a prospective cohort study, men from the Swedish Conscript Registry investigated 1968-2005 (n = 1 610 437; mean age, 18.6 years were followed 5-42 years (median, 23.0 years; interquartile range, 15.0-32.0), 5492 first hospitalizations for heart failure occurred (mean age at diagnosis, 46.6 (SD 8.0) years). Compared with men with a body mass index (BMI) of 18.5-20.0 kg/m2, men with a BMI 20.0-22.5 kg/m2 had an hazard ratio (HR) of 1.22 (95% CI, 1.10-1.35), after adjustment for age, year of conscription, comorbidities at baseline, parental education, blood pressure, IQ, muscle strength, and fitness. The risk rose incrementally with increasing BMI such that men with a BMI of 30-35 kg/m2 had an adjusted HR of 6.47 (95% CI, 5.39-7.77) and those with a BMI of >/=35 kg/m2 had an HR of 9.21 (95% CI, 6.57-12.92). The multiple-adjusted risk of heart failure per 1 unit increase in BMI ranged from 1.06 (95% CI, 1.02-1.11) in heart failure associated with valvular disease to 1.20 (95% CI, 1.18-1.22) for cases associated with coronary heart disease, diabetes, or hypertension. CONCLUSION: We found a steeply rising risk of early heart failure detectable already at a normal body weight, increasing nearly 10-fold in the highest weight category. Given the current obesity epidemic, heart failure in the young may increase substantially in the future and physicians need to be aware of this.

Heart Failure in Late Pregnancy and Postpartum: Incidence and Long-Term Mortality in Sweden From 1997 to 2010
- 2017
-
In: Journal of Cardiac Failure. - : Elsevier BV. - 1071-9164. ; 23:5, s. 370-378
-
Journal article (peer-reviewed)abstract
- 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.

Journal article (peer-reviewed)abstract
- Aim: We aimed to characterize the clinical course with focus on pharmacological management of peripartum cardiomyopathy (PPCM) in Sweden. Methods: Twenty-four consecutive patients were retrospectively identified among women presenting with PPCM in Western Sweden. Of these, 14 had concomitant preeclampsia. There was only one fatality. The mean (standard deviation) left ventricular ejection fraction (LVEF) at diagnosis was 35.0 ± 9.9%. Ten women, 47.6%, required intensive care unit (ICU) admission. All patients received b-blockers (BB) and angiotensin-converting enzyme inhibitors/angiotensin II receptor blockers (ACE-I/ARB), which were tapered off over a mean/median period of 3.3/2.5 years with only one case of worsening heart failure. The mean follow-up for medication was 7.9± 2.6 years. Early and late/non-recovery was defined as New York Heart Association (NYHA) functional class I and NYHA II–IV at one year, respectively. Late recovery was associated with larger LVEDD at diagnosis (56.8 versus 62.4 mm) was associated with late recovery, p=.02. Results and conclusions: PPCM had an overall good prognosis in this cohort. Left ventricular dilation at presentation was a predictor of worse prognosis. Concurrent preeclampsia was common, but was associated with better prognosis. Medication was safely discontinued in 75% of patient.

Does the target dose of neurohormonal blockade matter for outcome in Systolic heart failure in octogenarians?
- 2015
-
In: International Journal of Cardiology. - : Elsevier BV. - 0167-5273. ; 187, s. 666-672
-
Journal article (peer-reviewed)abstract
- Background: In elderly patients with chronic heart failure (CHF), a gap exists between widespread use of lower doses of angiotensin-converting enzyme inhibitors (ACEIs)/angiotensin-receptor blockers (ARBs) and beta-blockers (BBs) and guideline recommendations. Therefore, the aim of the present study was to investigate whether patients receiving >= 50% target dose outperform those receiving <50% target dose, despite maximum up-titration, and whether the target dose outperforms all other doses. Methods and Results: Patients (n=185) aged >= 80 years with CHF and left ventricular ejection fraction >= 40% referred (between January 2000 and January 2008) to two CHF outpatient clinics at two university hospitals, were included and retrospectively studied. Of the study population, 53% received the target dose of ACEIs/ARBs, whereas 26% received <50% of the target dose. Half received <50% of the target dose of BBs and 21% received the target dose. After >= 5 years of follow-up, all-cause mortality was 76.8%. Patients who received the target dose of ACEIs/ARBs had higher survival rates from all-cause mortality than those receiving <50% of target dose (HR = 0.6, 95% CI 0.4-0.9, P = 0.033), but those receiving >= 50% of target dose did not statistically differ from those who achieved target dose. This dose-survival relationship was not the case for BBs. Conclusions: Target dose of ACEIs/ARBs is associated with reduced all-cause five-year mortality in very old patients with systolic heart failure, despite that this was achievable in only about half of the patients. However, the clinical outcome of BB therapy is independent of BB dose when the target heart rate is achieved. (C) 2015 Elsevier Ireland Ltd. All rights reserved.
