Abstract

Introduction: Some available experimental studies have reported that hydrophilic statins might have advantages compared with lipophilic statins in patients with coronary artery disease (CAD). Therefore, we performed a meta-analysis of randomized controlled trials (RCTs) investigating the potential differences of lipophilic and hydrophilic statins in patients with CAD.

Methods: We systematically searched selected electronic databases up to September 2016 to select RCTs, which compared clinical outcomes of hydrophilic vs lipophilic statins. Primary endpoints were cardiovascular (CV) events: major adverse cardiac events, myocardial infarction, cardiac revascularization, stroke, CV death, CV hospitalization, and all-cause mortality. Secondary endpoints were safety parameters: drug discontinuation, statin-associated muscle symptoms and alanine aminotransferase level increase.

Results: A total of 11,697 patients from 11 RCTs, randomly allocated to lipophilic (n = 5736) or hydrophilic statins (n = 5961), with a mean follow-up 14 months, were included in the meta-analysis. In comparison with hydrophilic, the lipophilic statins showed similar risk reduction for major adverse cardiac events (relative risk = 0.969, 95% confidence interval [CI], 0.835-1.125, P = .682), myocardial infarction (0.880, 95% CI: 0.731-1.058, P = .174), CV death (0.757, 95% CI: 0.486-1.180, P = .219), and all-cause mortality (0.797, 95% CI: 0.590-1.075, P = .137), as well as cardiac revascularization, stroke, drug discontinuation, and statin-associated muscle symptoms. CV hospitalization was lower (0.789, 95% CI: 0.643-0.969, P = .024) and alanine aminotransferase elevation was higher (2.689, 95% CI: 1.841-3.954, P ≤ .001) in lipophilic than in hydrophilic-treated patients.

Conclusions: In conclusion, similarity between hydrophilic and lipophilic statins holds between various clinical CAD settings.
