BackgroundThe prognostic impact of chronic obstructive pulmonary disease (COPD) on heart failure (HF) with preserved ejection fraction (HFpEF) patients and its clinical characteristics have not yet been fully examined.MethodsThe Japanese Heart Failure Syndrome with Preserved Ejection Fraction (JASPER) registry is a nationwide, observational, prospective registration of consecutive Japanese hospitalized HFpEF patients with left ventricular ejection fraction (LVEF) of ≥50%. Among 535 patients enrolled in the registry, 10 lacking COPD data, and seven who died during the first hospitalization, were excluded. Finally, 518 patients were enrolled in this analysis. We divided these patients into two groups: the COPD group (n=40, 7.7%) and the non-COPD group (n=478, 92.3%). This analysis had two primary endpoints: (1) all-cause death and (2) all-cause death or rehospitalization for HF.ResultsThe COPD group showed a higher prevalence of male sex (70.0% vs. 48.1%, p=0.008), history of prior hospitalization for HF (63.2% vs. 35.1%, p=0.001), smoking history (71.8% vs. 43.3%, p=0.001), and a higher usage of loop diuretics (70.0% vs. 50.0%, p=0.015). In the follow-up period after discharge (median 733 days), there were 82 all-cause deaths and 127 rehospitalizations for HF. In the Kaplan-Meier analysis, the COPD group showed higher all-cause death and reached the composite endpoint more often than in the non-COPD group (all-cause death, log-rank 0.035; all-cause death or rehospitalization for HF, log-rank 0.025). In the Cox proportional hazard analysis, COPD was a predictor of all-cause death (hazard ratio 1.957, 95% confidence interval 1.037-3.694, p=0.038) and the composite endpoint (hazard ratio 1.694, 95% confidence interval 1.064-2.697, p=0.026).ConclusionsCOPD is associated with adverse prognosis in hospitalized patients with HFpEF.Copyright © 2019 Japanese College of Cardiology.
