The present study compared the long-term effects of ET on exercise capacity, diastolic function, and quality of life (QoL) in patients with DD vs. HFpEF. Methods A total of n=43 patients with asymptomatic DD (n=19) or HFpEF [DD and New York Heart Association (NYHA) ≥II, n=24] and left ventricular ejection fraction ≥50% performed a combined endurance/resistance training over 6months (2–3/week) on top of usual care. Cardiopulmonary exercise testing, echocardiography, and QoL were obtained at baseline and follow-up. Results Patients were 62±8 years old (37% female). In the HFpEF group, 67% of patients were in NYHA class II (33% in NYHA III). Exercise capacity (peak oxygen consumption, peak VO2) differed at baseline (DD 29.2±8.7mL/min/kg vs. HFpEF 17.8±4.6 mL/min/kg; P=0.004). After 6months, peak VO2 increased significantly (P<0.044) to 19.7±5.8 mL/min/kg in the HFpEF group and also in the DD group (to 32.8±8.5mL/min/kg; P<0.002) with no overall difference between the groups (P=0.217). E/e′ ratio (left ventricular filling index) decreased from 12.2±3.5 to 10.1±3.0 (P<0.002) in patients with HFpEFand also in patients with DD (10.7±3.1 vs. 9.5±2.3; P=0.03; difference between groups P=0.210). In contrast, left atrial volume index decreased in the HFpEF group (P<0.001) but remained stable within the DD group (difference between groups P=0.015). After 6 months, physical QoL (Minnesota living with heart failure Questionnaire, 36-item short form health survey), general health perception, and 9-item patient health questionnaire score only improved in HFpEF (P<0.05). In contrast, vitality improved in both groups (difference between groups P=0.708). Conclusion A structured 6 months ET programme effectively improves exercise capacity and diastolic function in patients with DD and overt HFpEF. Therefore, controlled lifestylemodification with physical activity is effective both in DD and HFpEF."],["dc.identifier.doi","10.1002/ehf2.12007"],["dc.identifier.fs","610857"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/11651"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/58349"],["dc.language.iso","en"],["dc.notes.intern","Merged from goescholar"],["dc.relation.issn","1879-0844"],["dc.rights","CC BY-NC-ND 4.0"],["dc.rights.uri","https://creativecommons.org/licenses/by-nc-nd/4.0"],["dc.title","Effects of long-term endurance and resistance training on diastolic function, exercise capacity, and quality of life in asymptomatic diastolic dysfunction vs. heart failure with preserved ejection fraction"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

We tested the association of 25-hydroxyvitamin D [25(OH)D] serum levels with mortality, hospitalizations, cardiovascular risk factors, and echocardiographic parameters in patients with asymptomatic diastolic dysfunction (DD) or newly diagnosed HFpEF. METHODS AND RESULTS: We measured 25(OH)D serum levels in outpatients with risk factors for DD or history of HF derived from the DIAST-CHF study. Participants were comprehensively phenotyped including physical examination, echocardiography, and 6 min walk test and were followed up to 5 years. Quality of life was evaluated by the Short Form 36 (SF-36) questionnaire. We included 787 patients with available 25(OH)D levels. Median 25(OH)D levels were 13.1 ng/mL, mean E/e' medial was 13.2, and mean left ventricular ejection fraction was 59.1%. Only 9% (n = 73) showed a left ventricular ejection fraction <50%. Fifteen per cent (n = 119) of the recruited participants had symptomatic HFpEF. At baseline, participants with 25(OH)D levels in the lowest tertile (≤10.9 ng/L; n = 263) were older, more often symptomatic (oedema and fatigue, all P ≤ 0.002) and had worse cardiac [higher N-terminal pro-brain natriuretic peptide (NT-proBNP) and left atrial volume index, both P ≤ 0.023], renal (lower glomerular filtration rate, P = 0.012), metabolic (higher uric acid levels, P < 0.001), and functional (reduced exercise capacity, 6 min walk distance, and SF-36 physical functioning score, all P < 0.001) parameters. Increased NT-proBNP, uric acid, and left atrial volume index and decreased SF-36 physical functioning scores were independently associated with lower 25(OH)D levels. There was a higher risk for lower 25(OH)D levels in association with HF, DD, and atrial fibrillation (all P ≤ 0.004), which remained significant after adjusting for age. Lower 25(OH)D levels (per 10 ng/mL decrease) tended to be associated with higher 5 year mortality, P = 0.05, hazard ratio (HR) 1.55 [1.00; 2.42]. Furthermore, lower 25(OH)D levels (per 10 ng/mL decrease) were related to an increased rate of cardiovascular hospitalizations, P = 0.023, HR = 1.74 [1.08; 2.80], and remained significant after adjusting for age, P = 0.046, HR = 1.63 [1.01; 2.64], baseline NT-proBNP, P = 0.048, HR = 1.62 [1.01; 2.61], and other selected baseline characteristics and co-morbidities, P = 0.043, HR = 3.60 [1.04; 12.43].

Methods A cross-sectional analysis from the prospective cohort programme Prevalence and Clinical Course of Diastolic Dysfunction and Heart Failure (DIAST-CHF) that included a total of 1937 patients (age, 50–85 years) with >1 risk factor (hypertension, atherosclerotic disease, diabetes mellitus, and obstructive sleep apnoea) was carried out. Besides comprehensive clinical phenotyping, standardized 6min walk test and state-of-the-art echocardiography were performed, and blood samples for biomarker assessment were obtained. Patients with an ejection fraction <50% or without evaluable exercise test were excluded from this analysis. Results One thousand three hundred eighty-seven patients fulfilled all criteria for this analysis. In the univariate analysis, 6 min walk distance was inversely related to E/e′ values (P<0.001). In the multivariate analysis, 6 min walk distance decreased significantly with age, female sex, increasing body mass index, diabetes, chronic obstructive lung disease, and peripheral artery disease. However, the association of 6 min walk distance with resting parameters of diastolic function was significantly attenuated with multivariate regression. In contrast, mid-regional pro-adrenomedullin, mid-regional pro-atrial natriuretic peptide, and N-terminal pro-B-type natriuretic peptide were independently associated with submaximal exercise capacity when added to the base model (all P<0.001). Conclusions Classical risk factors for heart failure and neuroendocrine activation are independently associated with submaximal exercise capacity, while diastolic function parameters obtained at rest were not. This observation substantiates the role of co-morbidities as relevant contributors to the clinical picture of HFpEF and the limitation of resting indices of diastolic function for diagnosing HFpEF."],["dc.identifier.doi","10.1002/ehf2.12034"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/11998"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/58413"],["dc.language.iso","en"],["dc.notes.intern","Merged from goescholar"],["dc.rights","CC BY-NC-ND 4.0"],["dc.rights.uri","https://creativecommons.org/licenses/by-nc-nd/4.0"],["dc.title","Determinants of submaximal exercise capacity in patients at risk for heart failure with preserved ejection fraction-results from the DIAST-CHF study"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]
