BACKGROUND: The gender differences in the prognosis of Asian patients with acute heart failure (AHF) remain to be elucidated. METHODS AND RESULTS: One thousand fifty AHF patients were enrolled. The patients were assigned to a female group (n=354) and a male group (n=696). A Kaplan-Meier curve showed that the cardiovascular survival rate of the female group was significantly lower than that of the male group (p=0.005). A multivariate Cox regression model identified female gender [hazard ratio (HR): 1.381, 95% CI: 1.018-1.872] as an independent predictor of 730-day cardiovascular death. In subgroup analysis by age, in patients over 79 years, female gender significantly increased the cardiovascular death (HR: 1.715, 95% CI: 1.088-2.074, p<0.001) with a significant interaction (p-value for interaction<0.001). The prognosis, including cardiovascular death, was significantly poorer among elderly female patients (≥79 years) than among elderly male patients (p=0.019). The multivariate Cox regression model identified female gender as an independent predictor of 730-day cardiovascular death in patients who were older than 79 years of age (HR, 1.943; 95% CI, 1.192-3.167). CONCLUSIONS: Female gender was associated with poor prognosis in AHF patients. In particular, old age (≥79 years) was associated with adverse outcomes in female patients with AHF.
