Efficacy of red yeast rice extract on myocardial infarction patients with borderline hypercholesterolemia: A meta-analysis of randomized controlled trials

Sci Rep. 2020 Feb 17;10(1):2769. doi: 10.1038/s41598-020-59796-5.

Abstract

Red yeast rice (RYR) extract is widely used for improving cardiovascular outcomes and lipid profiles. However, RYR efficacy on cardiovascular outcomes in myocardial infarction (MI) patients remains unclear. This meta-analysis assessed efficacy of RYR extract in MI patients with borderline hypercholesterolemia. PubMed, CENTRAL, CINAHL, Scopus, Web of Science, and Clinicaltrials.gov were systematically searched from inception through May 2019 for relevant publications. Seven studies with 10,699 MI patients diagnosed with borderline hypercholesterolemia were included. Follow-up periods ranged from 4 weeks - 4.5 years and the studies were overall of high quality with low risk of bias. RYR extract (1,200 mg/day) reduced nonfatal MI (risk ratio (RR) = 0.42, 95% CI 0.34 to 0.52), revascularization (RR = 0.58, 95% CI 0.48 to 0.71), and sudden death (RR = 0.71, 95% CI 0.53 to 0.94). RYR extract also lowered LDL (weighted mean difference (WMD) = -20.70 mg/dL, 95% CI -24.51 to -16.90), TC (WMD = -26.61 mg/dL, 95% CI -31.65 to -21.58), TG (WMD = - 24.69 mg/dL, 95% CI -34.36 to -15.03), and increased HDL levels (WMD = 2.71 mg/dL, 95% CI 1.24 to 4.17). This meta-analysis indicated that RYR extract in MI patients with borderline hypercholesterolemia is associated with improved cardiovascular outcomes and lipid profiles.
