Sex Differences in Heart Failure Mortality with Preserved, Mildly Reduced and Reduced Ejection Fraction: A Retrospective, Single-Center, Large-Cohort Study.

Background: Heart failure (HF) is one of the leading causes of death worldwide. Studies show that women have better survival rates than men despite higher hospitalizations. However, little is known about differences in mortality and predictors of death in women and men with HF with preserved (HFpEF), mildly reduced (HFmrEF), and reduced ejection fraction (HFrEF).

Why do patients with chagasic cardiomyopathy have worse outcomes than those with non-chagasic cardiomyopathy?

Background: Heart failure is a highly prevalent disease, the prognosis of which depends on different predictive factors.

Objective: Chagas disease is a predictor of poor prognosis in patients with chronic heart failure (HF). The purpose of this study is to investigate whether this condition also predicts poor outcome in acutely decompensated patients.
