Efficacy and safety of Yangxinshi tablet for chronic heart failure: A systematic review and meta-analysis.

ABSTRACT

BACKGROUND: The specific benefits of Yangxinshi tablet (YXST) in the treating chronic heart failure (CHF) remain uncertain. AIM: To systematically evaluate the efficacy and safety of YXST in the treatment of CHF. METHODS: Randomized controlled trials (RCTs) investigating YXST for CHF treatment were retrieved from eight public databases up to November 2023. Meta-analyses of the included clinical studies were conducted using Review Manager 5.3. RESULTS: Twenty RCTs and 1845 patients were included. The meta-analysis results showed that the YXST combination group, compared to the conventional drug group, significantly increased the clinical efficacy rate by 23% [relative risk (RR) = 1.23, 95%CI 1.17-1.29], P < 0.00001), left ventricular ejection fraction by 6.69% [mean difference (MD) = 6.69, 95%CI 4.42-8.95, P < 0.00001] and 6-min walk test by 49.82 m (MD = 49.82, 95%C 38.84-60.80, P < 0.00001), and reduced N-terminal pro-B-type natriuretic peptide by 1.03 ng/L [standardized MD (SMD) = -1.03, 95%CI -1.32 to -0.74, P < 0.00001], brain natriuretic peptide by 80.95 ng/L (MD = -80.95, 95%CI -143.31 to -18.59, P = 0.01), left ventricular end-diastolic diameter by 3.92 mm (MD = -3.92, 95%CI -5.06 to -2.78, P < 0.00001), and left ventricular end-systolic diameter by 4.34 mm (MD = -4.34, 95%CI -6.22 to -2.47, P < 0.00001). Regarding safety, neither group reported any serious adverse events during treatment (RR = 0.54, 95%CI 0.15-1.90, P = 0.33). In addition, Egger's test results indicated no significant publication bias (P = 0.557). CONCLUSION: YXST effectively improves clinical symptoms and cardiac function in patients with CHF while maintaining a favorable safety profile, suggesting its potential as a therapeutic strategy for CHF.
