Effects of sacubitril/valsartan on renal function and outcome in patients with heart failure and reduced ejection fraction: an Italian cohort study

Abstract

Background: Sacubitril/valsartan (S/V) is a cornerstone treatment for heart failure (HF). Beneficial effects on hospitalization rates, mortality, and left ventricular remodeling have been observed in patients with heart failure and reduced ejection fraction (HFrEF). Despite the positive results, the influence of S/V on renal function during long-term follow-up has received little attention. Aims: We investigated the long-term effects of S/V therapy on renal function in a large cohort of patients with HFrEF. Additionally, we examined the effects of the drug in patients with chronic kidney disease (CKD) compared to those with preserved renal function and identified primary risk characteristics Methods: We studied 776 outpatients with HFrEF and left ventricular ejection fraction (LVEF) 1000 pg/ml (HR 1.95[1.38, 2.77], p 50 mg (HR 2.04 [1.48, 2.82], p 1.5 mg/dl occurred during follow-up (HR 1.74 [1.24, 2.43], p 1.5 mg/dl, and atrial fibrillation were independent predictors of adverse events. Conclusion: Long-term S/V therapy is associated with improved outcomes and renal protection in patients with HFrEF. This effect is more pronounced in patients who tolerate escalating doses. The positive effects of the drug are maintained in both CKD and preserved renal function. Future research may study the safety and underlying causes of current protection.
