Are guideline-recommended treatments for heart failure (HF) effective and safe in patients with Chagas disease?This trial found that in patients with heart failure with reduced ejection fraction (HFrEF) due to Chagas cardiomyopathy, sacubitril/valsartan was not significantly different from enalapril in the composite outcome of cardiovascular death or hospitalization for HF, but led to a greater reduction in N-terminal pro-B-type natriuretic peptide.In patients with HFrEF due to Chagas disease, sacubitril/valsartan did not result in better clinical outcomes.
