Objective: We compared the effects of high-intensity statin monotherapy versus moderate-intensity statin and ezetimibe combination therapy on major adverse cardiovascular events (MACE) in patients with acute myocardial infarction (AMI).
Methods: Using the Korean National Health Insurance Service database, we screened 82,941 patients with AMI who underwent percutaneous coronary intervention (PCI) between 2013 and 2016. Among them, we identified 9,908 patients treated with atorvastatin 40 mg (A40, n=4,041), atorvastatin 20 mg + ezetimibe 10 mg (A20+E10, n=233), rosuvastatin 20 mg (R20, n=5,251), or rosuvastatin 10 mg + ezetimibe 10 mg (R10+E10, n=383). The primary outcome was MACE, a composite of all-cause death, non-fatal myocardial infarction undergoing PCI, repeat revascularization, and ischemic stroke. Multivariable analyses were performed using the inverse probability of treatment weighting method.
Results: The incidence rate of MACE in the overall population was 42.97 cases per 1,000 person-years. There was no significant difference in the risk of composite outcomes of MACE between the groups. However, the R10+E10 group showed a higher risk of all-cause death (hazard ratio, 2.07; 95% confidence interval, 1.08?3.94) than the A40 group (reference group) in the weighted multivariable model.
Conclusions: In this study, there was no significant difference in the composite outcome of MACE between high-intensity statin monotherapy and moderate-intensity statin and ezetimibe combination therapy.
