Abstract

    Background: Intensive statin therapy reduces cardiovascular events in acute coronary syndrome. The data concerning the long-term clinical impacts of statin therapy between ST-segment elevation myocardial infarction (STEMI) and non-STEMI (NSTEMI) after drug-eluting stent implantation are limited. We compared the 2-year clinical outcomes between these 2 groups after statin therapy.
    Materials and methods: A total of 30,616 Korean patients with acute myocardial infarction (AMI) were enrolled. Among them, 13,686 patients were classified as group A (STEMI statin user), 3,824 patients were as group B (STEMI statin nonuser), 10,398 patients were as group C (NSTEMI statin user), and 2,708 patients were as group D (NSTEMI statin nonuser). The major clinical endpoint was the occurrence of major adverse cardiac events (MACE) defined as all-cause death, recurrent myocardial infarction (re-MI), and any repeat revascularization during a 2-year follow-up period.
    Results: After adjustment, the cumulative risks of MACE (adjusted hazard ratio [aHR] = 1.112 [1.002-1.235]; P = 0.047), all-cause death (aHR = 1.271 [1.054-1.532]; P = 0.012), and target vessel revascularization (TVR, aHR = 1.262 [1.049-1.518]; P = 0.014) in group C were significantly higher than group A. The cumulative risks of MACE, all-cause death, and cardiac death of the statin nonuser group (groups B and D) were significantly higher compared with statin user group (groups A and C).
    Conclusions: Statin therapy was more effective in reducing the cumulative risks of MACE, all-cause death, and TVR in the STEMI group than NSTEMI group in Korean patients with AMI after successful drug-eluting stent implantation.
