BACKGROUND: Literature describing recovery of left ventricular (LV) function post sacubitril/valsartan treatment and the optimal management of heart failure (HF) patients receiving sacubitril/valsartan remain sparse.
METHODS: We recruited 437 consecutive chronic HF patients with baseline left ventricular ejection fraction (LVEF) less than 40%, who were treated with sacubitril/valsartan. All patients underwent routine echocardiographic measurement.
RESULTS: During treatment period, recovery of LVEF to 50% or greater was observed in 77 (17.6%) patients. After multivariate analysis, recovery of LV dysfunction was associated with non-ischemic etiology of HF, smaller baseline LV end-diastolic diameter (LVEDD), and higher initial dosage of sacubitril/valsartan. Compared to those without recovery of LV dysfunction, death from cardiovascular causes or first unplanned hospitalization for HF (CVD/HFH) were significantly lower in patients with LVEF recovery [11.7% vs. 24.4%, hazard ratio (HR) 0.42, p = 0.014]. Among patients with recovery of LVEF, 51 patients continued to receive the same dosage of sacubitril/valsartan had higher LVEF and were less likely to have deterioration of LVEF than the other 26 patients who received either tapering dose of sacubitril/valsartan or switching from sacubitril/valsartan to renin-angiotensin-system blockers (LVEF 56.4 ± 5.3% vs. 45.0 ± 12.8%, p < 0.001; ΔLVEF 1.2 ± 5.1% vs. -9.3 ± 12.0%, p < 0.001). CVD/HFH occurred more frequently in the taper group than the maintenance group (23.1% vs. 5.9%, HR 0.22, p = 0.035).
CONCLUSIONS: Non-ischemic etiology of HF, smaller baseline LVEDD, and higher initial dosage of sacubitril/valsartan could predict better recovery of LV function. Among patients with functional recovery, tapering sacubitril/valsartan dose was associated with deterioration of recovered heart function and had less favorable prognosis during follow-up.
