Abstract Background Congestive heart failure (CHF) is one of the leading causes of death from cardiovascular disease and years lived with disability. Studies showed that women had better survival than men despite higher hospitalizations in women. However, there is evidence of a gender-associated risk of dying of heart failure of different types of cardiomyopathies (CMP). Purpose To analyze the mortality of CHF due to different types of CMP in women and men Methods From February 2017 to September 2020, we analyzed the mortality and the predictors of death in women and men with CHF (Framingham criteria) in five types of CMP (ischemic, idiopathic, hypertensive, Chagas, and valve disease). Baseline data included clinical characteristics and echocardiographic findings. Statistical analyses used the Kaplan-Meier (K-M) method and the Cox proportional hazards methods to analyze death rates and search for predictors of death for women and men for each CMP. Results We studied 12,015 patients, mean of 63.8±14.3 years, 6637 (55%) males. For all patients, death occurred in 27.5%, 15.3%, 17.5%, 40.1%, and 24.4%, respectively, for ischemic, idiopathic, hypertensive, Chagas, and valve CMPs (p<0.0001). HFrEF was more prevalent in idiopathic (51.2%) and Chagas (49.9%), and for HFpEF valve disease (80.4%), hypertensive (51.9%), and ischemic (44.4%). Compared to men, women were older, had a higher baseline mean left ventricular ejection fraction (LVEF), and a lower left ventricular diastolic diameter (LVDD) for all five types of CMP (p<0,001). Over a 3-years follow-up period, the cumulative incidence of death was higher in men with ischemic CMP (38% vs. 31%; p=0.037) and Chagas CMP (48% vs. 38%; p<0,001) but similar for idiopathic, hypertensive, and valve disease CMP (figure). Cox regression analysis for death, for each CMP, adjusted for confounders such as age, sex, previous myocardial infarction, diabetes, previous stroke, chronic kidney disease (CKD), atrial fibrillation (AF), any cardiac surgery, cardiac pacemakers, and LVEF showed that men were an independent predictor of death only for Chagas CMP (HR=1,28; 95% CI: 1.08–1.43; p=0.009). Conclusion Men were at a higher risk of death in ischemic and Chagas CMP but not for idiopathic, hypertensive, and valve CMP. The other main predictors of death were similar for all types of CMP, namely CKD, stroke, diabetes, and AF. Funding Acknowledgement Type of funding sources: None.
