BACKGROUNDS: High-intensity statin is recommended for patients undergoing percutaneous coronary intervention (PCI), and ezetimibe is recommended to be added in patients not achieving low-density lipoprotein cholesterol (LDL-C) targets. Moderate-intensity statin plus ezetimibe can reduce LDL-C levels similar to high-intensity statin. The aim of this study is to examine the long-term efficacy and safety of moderate-intensity statin plus ezetimibe as the first-line strategy compared to high-intensity statin in patients undergoing PCI. METHOD: Data was obtained from the Health Insurance Review and Assessment Service database of South Korea. Patients who underwent PCI from 2012 to 2017 were included. The primary efficacy endpoint was major adverse cardiac cerebrovascular events (MACCEs), a composite of all-cause death, revascularization, or ischemic stroke. The safety endpoint was new-onset diabetes mellitus (DM). RESULTS: A total of 45,501 patients received high-intensity statin (n = 38,340) or moderate-intensity statin plus ezetimibe (n = 7,161). Among propensity-score-matched 7,161 pairs, MACCEs occurred in 1,460 patients with high-intensity statin and 1,406 patients with moderate-intensity statin plus ezetimibe (33.8% vs. 31.9%, hazard ratio 0.96, 95% confidence interval 0.89-1.03, P = 0.27) at a median follow-up of 2.7 years. DM was newly diagnosed in 398 patients with high-intensity statin and 342 patients with moderate-intensity statin plus ezetimibe (12.5% vs. 10.7%; hazard ratio 0.84, 95% confidence interval 0.73-0.97, P = 0.02). CONCLUSION: In patients undergoing PCI, moderate-intensity statin plus ezetimibe demonstrated a similar risk of MACCEs but a lower risk of new-onset DM than high-intensity statin. Early combination treatment of moderate-intensity statin and ezetimibe may be a useful and safe lipid-lowering strategy after PCI.
