Abstract
BACKGROUND: The effect of sacubitril-valsartan in heart failure patients with mid-range (HFmEF) and preserved (HFpEF) ejection fractions remains unclear. This study aimed to investigate the clinical benefits of sacubitril-valsartan in HFmEF and HFpEF patients. METHODS: PubMed, EMBASE, Cochrane Library, and China National Knowledge Infrastructure were searched from inception to 29 February 2020 to identify pertinent articles. Studies meeting the inclusion criteria were included and analysed. RESULTS: Six (6) studies, with a total of 5,503 patients, were included. Compared with angiotensin-converting enzyme inhibitors and angiotensin receptor blockers, sacubitril-valsartan significantly reduced the rate of HF hospitalisation (risk ratios, 0.84; 95% CI, 0.77-0.91; p<0.001) and improved the New York Heart Association class (risk ratios, 1.25; 95% CI, 1.10-1.43; p=0.001) in HFmEF and HFpEF patients. Both the cardiovascular mortality and all-cause mortality were not significantly decreased by sacubitril-valsartan. In addition, there were no significant between-group differences in the N-terminal pro-B-type natriuretic peptide and left ventricular ejection fraction changes. Regarding safety, sacubitril-valsartan was likely to increase the risk of hypotension, but the incidence of serum creatinine elevation was significantly lower in the sacubitril-valsartan group than in the angiotensin-converting enzyme inhibitors and angiotensin receptor blockers group. CONCLUSIONS: This meta-analysis suggests that sacubitril-valsartan may be an effective and safe strategy with which to improve the clinical symptoms and reduce HF hospitalisation in HFmEF and HFpEF patients.
