ABSTRACT

Background Qiliqiangxin (QLQX) capsules are a commonly used proprietary Chinese medicine for the adjuvant treatment of chronic heart failure (CHF) in China. In recent years, several randomized controlled trials (RCTs) have reported on the efficacy and safety of QLQX combined with sacubitril/valsartan for CHF. Objective The purpose of this study was to systematically analyze the clinical efficacy and safety of QLQX combined with sacubitril/valsartan in the management of CHF and to provide clinicians as well as scientists with optimal evidence-based medical evidence. Methods We searched RCTs to evaluate the efficacy and safety of QLQX combined with sacubitril/valsartan in the treatment of CHF in the Wanfang Database, China National Knowledge Infrastructure, China Science and Technology Journal Database, PubMed, Embase, and Cochrane Library databases from their inception until January 8, 2022. RCTs on QLQX in combination with sacubitril/valsartan for CHF were included. The outcome measures considered were total effective rate, left ventricular ejection fraction (LVEF), left ventricular end-diastolic dimension (LVEDD), 6-minute walking distance (6-MWD), and adverse events. The quality of the included RCTs was assessed thereafter using the Cochrane risk of bias tool. RevMan 5.3 software was used to conduct the meta-analysis. Results The meta-analysis included 17 trials involving 1427 CHF patients. The results indicated that with sacubitril/valsartan administration combined with QLQX treatment, the total effective rate (relative risk (RR) = 1.24; 95% confidence interval (CI) (1.17, 1.31); p < 0.01), LVEF (mean difference (MD) = 6.20; 95% CI (5.36, 7.05; p < 0.01)), and 6-MWD (MD = 55.87; 95% CI (40.66, 71.09); p < 0.01) of CHF patients were significantly increased, and the LVEDD value of CHF patients was noted to be significantly reduced (MD = −3.98; 95% CI (−4.47, −3.48); p < 0.01). Moreover, there was no increase in the number of adverse events during treatment (RR = 0.67; 95% CI (0.33, 1.34); p < 0.01). Conclusions This study indicated that in CHF patients, on the basis of sacubitril/valsartan treatment, combination with QLQX can potentially enhance the total effective rate, improve LVEF and 6-MWD, and reduce LVEDD values, with good safety. However, considering the poor quality of the included studies, a multicenter, randomized, double-blind controlled study is needed for further confirmation.
