Background: Controversy has persisted over the clinical benefits of low-dose sacubitril/valsartan in patients with heart failure . Hypothesis: Low-dose sacubitril/valsartan might also be effective and safe in HF patients. Methods: Electronic databases including PubMed, Ovid, and Cochrane Library were systematically retrieved from inception to August 5, 2021. Review manager 5.4 and Stata 15.1 were employed in this systematic review and meta-analysis. Key efficacy outcomes of interest included HF ...更多
Background: Controversy has persisted over the clinical benefits of low-dose sacubitril/valsartan in patients with heart failure . Hypothesis: Low-dose sacubitril/valsartan might also be effective and safe in HF patients. Methods: Electronic databases including PubMed, Ovid, and Cochrane Library were systematically retrieved from inception to August 5, 2021. Review manager 5.4 and Stata 15.1 were employed in this systematic review and meta-analysis. Key efficacy outcomes of interest included HF hospitalization, all-cause mortality, left ventricular ejection fraction , N-terminal pro-B-type natriuretic peptide , together with New York Heart Association functional class. The safety outcome was systolic blood pressure . The grading of recommendations assessment, development, and evaluation approach was conducted to evaluate the quality of evidence for each outcome. Results: A total of 1269 studies were screened and 9 real-world studies met the inclusion criteria were included in the meta-analysis, with 1697 participants. Compared with low-dose sacubitril/valsartan, high-dose sacubitril/valsartan significantly reduced the risk of HF hospitalization and the risk of all-cause mortality . However, there were no appreciable differences in improvements of NYHA , changes of LVEF , changes of NT-proBNP and changes of SBP between groups with low-dose and high-dose sacubitril/valsartan. Conclusions: Compared with high-dose sacubitril/valsartan, low-dose sacubitril/valsartan was associated with increased risks of HF hospitalization and all-cause mortality. However, no distinct between-group differences in improvements of NYHA, changes of LVEF, changes of NT-proBNP and changes of SBP were observed.收起
