    BackgroundThe combination drug sacubitril/valsartan was reported to be superior to enalapril in reducing all-cause death, cardiovascular mortality, and heart failure (HF) hospitalizations in patients with cardiac insufficiency and reduced left ventricular ejection fraction (HFREF) with NYHA class II-IV.MethodsOur retrospective cohort study aimed to assess the effects of sacubitril/valsartan in addition to a beta-blocker and mineral receptor antagonist (MRA) in a group of HFREF patients with NYHA class II-III HF vs. conventional therapy (ACE inhibitor or angiotensin II receptor blocker added to a beta-blocker plus an MRA) administered to a control group of HFREF patients with comparable clinical features. In both groups, treatment was supplemented by a loop diuretic, usually furosemide, at variable doses. The primary outcomes were all-cause death and HF hospitalizations. Safety outcomes were symptomatic hypotension, angioedema, hyperkalemia, and worsening renal function.ResultsMortality at 6 months was 6.8% in patients taking sacubitril/valsartan vs. 34% in those on conventional therapy (odds ratio [OR] = 0.14; 95% CI: 0.04-0.49). Moreover, there was a 4.5% rate of HF hospitalizations in the sacubitril/valsartan group vs. 59% in the control group (OR = 0.03; 95% CI: 0.01-0.14). Safety outcomes were comparable in the two groups, although hypotension (systolic blood pressure < 100 mm Hg) was found in 15.9% of patients in the sacubitril/valsartan group vs. 5.7% in the control group (OR = 3.14; 95% CI: 0.94-10.55).ConclusionSacubitril/valsartan offered strong protection against all-cause death and HF hospitalizations at 6 months without any significant side effects. To validate this efficacious molecule, further postmarketing observational studies, focusing mainly on hypotension and angioedema are warranted.
