Abstract: Background:Little is known about factors associated with elevated N-terminal pro B-type natriuretic peptide (NT-proBNP) at the convalescent stage and their effects on 1-year outcomes in patients with heart failure with preserved ejection fraction (HFpEF). Methods and Results:This study included 469 patients with HFpEF. Elevated NT-proBNP was defined as the highest quartile. The first 3 quartiles (Q1–Q3) were combined together for comparison with the fourth quartile (Q4). Median NT-proBNP concentrations in Q1–Q3 and Q4 were 669 and 3,504 pg/mL, respectively. Multivariate logistic regression analysis revealed that low albumin (odds ratio [OR] 2.44; 95% confidence interval [CI] 1.35–4.39; P=0.003), low estimated glomerular filtration rate (OR 5.83; 95% CI 3.46–9.83; P
