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]. Conclusions Lower 25(OH)D levels were associated with reduced functional capacity in patients with DD or HFpEF and were significantly predictive for an increased rate of cardiovascular hospitalizations, also after adjusting for age, NT-proBNP, and selected baseline characteristics and co-morbidities.

A1 - Wachter, Rolf T1 - Contribution of comorbidities to functional impairment is higher in heart failure with preserved than with reduced ejection fraction JF - Clinical Research in Cardiology N2 - Background Comorbidities negatively affect prognosis more strongly in heart failure with preserved (HFpEF) than with reduced (HFrEF) ejection fraction. Their comparative impact on physical impairment in HFpEF and HFrEF has not been evaluated so far. Methods and results The frequency of 12 comorbidities and their impact on NYHA class and SF-36 physical functioning score (SF-36 PF) were evaluated in 1,294 patients with HFpEF and 2,785 with HFrEF. HFpEF patients had lower NYHA class (2.0 ± 0.6 vs. 2.4 ± 0.6, p < 0.001) and higher SF-36 PF score (54.4 ± 28.3 vs. 54.4 ± 27.7, p < 0.001). All comorbidities were significantly (p < 0.05) more frequent in HFrEF, except hypertension and obesity, which were more frequent in HFpEF (p < 0.001). Adjusting for age and gender, COPD, anemia, hyperuricemia, atrial fibrillation, renal dysfunction, cerebrovascular disease and diabetes had a similar (p for interaction > 0.05) negative effect in both groups. Obesity, coronary artery disease and peripheral arterial occlusive disease exerted a significantly (p < 0.05) more adverse effect in HFpEF, while hypertension and hyperlipidemia were associated with fewer (p < 0.05) symptoms in HFrEF only. The total impact of comorbidities on NYHA (AUC for prediction of NYHA III/IV vs. I/II) and SF-36 PF (r 2) in multivariate analyses was approximately 1.5-fold higher in HFpEF, and also much stronger than the impact of a 10% decrease in ejection fraction in HFrEF or a 5 mm decrease in left ventricular end-diastolic diameter in HFpEF. Conclusion The impact of comorbidities on physical impairment is higher in HFpEF than in HFrEF. This should be considered in the differential diagnosis and in the treatment of patients with HFpEF.
