Effectiveness of sacubitril/valsartan for patients with cancer therapy‑related cardiac dysfunction: A systematic review of descriptive studies

The present review assessed the effectiveness of sacubitril/valsartan in patients with cancer therapy-related cardiac dysfunction (CTRCD). Studies that included patients with CTRCD treated with sacubitril/valsartan were retrieved from the Medline, Embase, Cochrane Library and ClinicalTrials databases. Only descriptive studies on sacubitril/valsartan for patients with CTRCD were included in this review; therefore, all variables were qualitatively analyzed. A total of five studies comprising 109 patients were included. The duration from anticancer therapy to heart failure (HF) or from HF to the use of sacubitril/valsartan exhibited interindividual variations. In patients with CTRCD who were treated with sacubitril/valsartan, the left ventricular ejection fraction improved, N-terminal pro-B-type natriuretic peptide levels decreased and exercise tolerance improved, as indicated by the change in the New York Heart Association functional class. These clinical, echocardiographic and biochemical improvements were found for different dosages or treatment durations of sacubitril/valsartan. No difference was found between the baseline and follow-up serum creatinine and potassium levels. These findings, which are limited to descriptive studies, support the effectiveness of sacubitril/valsartan in improving heart function following CTRCD.
