BACKGROUND: Combining low-dose statin and ezetimibe reduces the low-density lipoprotein cholesterol (LDL-C) similar to high-dose statin. However, whether there is a difference in the effect of these 2 lipid-lowering regimes on endothelial function is still controversial. METHODS: We performed a systematic search of databases (MEDLINE [1950 to September 2011], EMBASE [1966 to September 2011]) and references of identified studies. Completely published randomized controlled trials comparing the effect of high-dose statin with low-dose stain plus ezetimibe on endothelial function (flow-mediated dilation [FMD] method) were included in this study. RESULTS: Six trials with a total of 213 participants were included in the meta-analysis. The pooled weighted mean difference of FMD did not differ between the 2 lipid-lowering regimes (0.22%; 95% confidence interval [CI]: -0.85%-1.29%, P = .68). Furthermore, no significant reduction in LDL-C and C-reactive protein (CRP) occurred with high-dose statin versus low-dose statin plus ezetimibe (pooled weighted mean differences of LDL-C and CRP were -4.12 mg/dL, 95% CI: -9.54-1.12 mg/dL, P = .12, and -0.02 mg/L, 95% CI: -0.31-0.27 mg/L, P = .89, respectively). CONCLUSIONS: Based on the currently available evidence, combining a low-dose statin with ezetimibe may provide similar beneficial effects on endothelial function as high-dose statin.
