Resum:	Following a heart failure (HF)-decompensation, there is scarce data about sex-related prognostic differences across left ventricular ejection fraction (LVEF) status. We sought to evaluate sex-related differences in 6-month mortality risk across LVEF following admission for acute HF. We retrospectively evaluated 4812 patients consecutively admitted for acute HF in a multicenter registry from 3 hospitals. Study end points were all-cause, cardiovascular, and HF-related mortality at 6-month follow-up. Multivariable Cox regression models were fitted to investigate sex-related differences across LVEF. A total of 2243 (46. 6%) patients were women, 2569 (53. 4%) were men, and 2608 (54. 2%) showed LVEF≥50%. At 6-month follow-up, 645 patients died (13. 4%), being 544 (11. 3%) and 416 (8. 6%) cardiovascular and HF-related deaths, respectively. LVEF was not independently associated with mortality (HR, 1. 02; 95% CI 0. 99-1. 05; P =0. 135). After multivariable adjustment, we found no sex-related differences in all-cause mortality (P value for interaction=0. 168). However, a significant interaction between sex and cardiovascular and HF mortality risks was found across LVEF (P value for interaction=0. 030 and 0. 007, respectively). Compared with men, women had a significantly lower risk of cardiovascular and HF-mortality at LVEF<25% and <43%, respectively. On the contrary, women showed a higher risk of HF-mortality at the upper extreme of LVEF (>80%). Following an admission for acute HF, no sex-related differences were found in all-cause mortality risk. However, when compared with men, women showed a lower risk of cardiovascular and HF-mortality at the lower extreme of LVEF. On the contrary, they showed a higher risk of HF death at the upper extreme.
