BACKGROUND: The 3-month period after hospitalization for acute cardiac failure is a vulnerable phase with the highest risk of mortality and rehospitalization. Safety and efficacy of early initiation of sacubitril/valsartan during the index hospitalization for acute decompensated heart failure (ADHF) is unclear. Therefore, we tested whether sacubitril/valsartan could result in a lower rate of a composite outcome of first hospitalization for heart failure and death from cardiovascular causes compared to inhibition of the renin-angiotensin system alone.

METHODS: We enrolled patients hospitalized for ADHF and reduced ejection fraction at 4 sites; patients were divided into a sacubitril/valsartan group or an angiotensin-converting enzyme inhibitor (ACEI)/angiotensin receptor blocker (ARB) group. All patients were followed up for 3 months after discharge. The primary endpoint was outcomes as a composite of death from cardiovascular causes and rehospitalization for heart failure.

RESULTS: In total, 251 patients who received sacubitril/valsartan and 251 patients who received ACEIs/ARBs had similar propensity scores and were included and compared. The primary endpoint was reached in 40 patients (15.9%) treated with sacubitril/valsartan and in 59 patients (23.5%) managed by ACEI/ARB (HR, 0.650; 95% CI: 0.435-0.971; p = 0.035). The NYHA class improved in 72.1% of patients in the sacubitril/valsartan group and in 59.8% of patients in the ACEI/ARB group (HR, 1.303; 95% CI: 1.097-1.548, p = 0.004). The key safety outcomes endpoints did not significantly differ.

CONCLUSIONS: Among patients hospitalized with ADHF and reduced left ventricular ejection fraction, we observed that sacubitril/valsartan therapy led to reduction in death from cardiovascular causes and rehospitalizations for heart failure when compared to ACEI/ARB therapy alone during the vulnerable phase. Our results support that sacubitril/valsartan may be administered early in the vulnerable phase after ADHF and improves NYHA class.
