- Abstract
- Background: NT-pro B-type natriuretic peptide (NT-proBNP) is a powerful prognostic factor for acute heart failure. We investigated whether NT-proBNP levels differ based on the type of heart failure present. Methods: Using the Korean Acute Heart Failure Registry, a prospective, multicenter cohort, we categorized pa-tients into two groups: de novo heart failure (DNHF, n = 1617) and acute decompensated chronic heart failure (ADHF, n = 1212). NT-proBNP levels were measured on admission. The primary outcome was all-cause mor-tality, and the secondary outcomes were re-hospitalization for heart failure and a composite of all-cause mor-tality or re-hospitalization for heart failure at 90 days and 1 year. Results: NT-proBNP levels were significantly lower in patients with DNHF than in those with ADHF (median 4213 vs. 5523 ng/L, p < 0.001). Compared to patients with DNHF, patients with ADHF had a significantly worse prognosis for 1-year all-cause mortality (adjusted hazard ratio (HR) = 1.46 [95% confidence interval (CI) = 1.07-1.98], p = 0.017). A higher NT-proBNP level was associated with higher 1-year all-cause mortality for both heart failure types (adjusted HR = 2.00, p = 0.002 in ADHF; adjusted HR = 2.41, p = 0.003 in DNHF). However, all-cause mortality risk was always higher in patients with ADHF than in those with DNHF for any given NT-proBNP level. Conclusion: NT-proBNP levels are an important prognostic factor for both DNHF and ADHF. Notably, patients with ADHF had consistently higher risks than those with DNHF with the same NT-proBNP level for 1-year all -cause mortality.
