Background: Very little data is available to evaluate the gender-specific role of N-terminal pro-B type natriuretic peptide (NT-proBNP). This study was performed to investigate whether there is a gender difference in the prognostic value of NT-proBNP in patients hospitalized for heart failure (HF). Methods and Results: A total of 2,280 patients hospitalized with HF (67.9±14.3 years, 50.9% women) from the nationwide registry database were analyzed. Composite events including all-cause mortality and HF readmission were assessed. During the mean follow-up period of 1,245±824 days, there were 1,067 cases of composite events (49.7%). NT-proBNP levels were significantly higher in patients with events than those without in both genders (P<0.001 for each). A higher NT-proBNP level was an independent predictor of events (highest vs. lowest tertile: hazard ratio [HR], 1.74; 95% confidence interval [CI], 1.25-2.43; P=0.001) in men, even after controlling for potential confounders. However, NT-proBNP was not associated with the occurrence of composite events in women in the same multivariable analysis (P>0.05). Conclusions: In patients with HF, the NT-proBNP level seems to be a more valuable marker in the prediction of long-term mortality and HF readmission in men than in women.
