Cilostazol-based triple versus potent P2Y12 inhibitor-based dual antiplatelet therapy in patients with acute myocardial infarction undergoing percutaneous coronary intervention.
Although potent P2Y12 inhibitor-based dual antiplatelet therapy (DAPT) has replaced clopidogrel-based therapy as the standard treatment in patients with acute myocardial infarction (AMI), there is a concern about the risk of bleeding in East Asian patients. We compared the efficacy and safety of cilostazol-based triple antiplatelet therapy (TAT) with potent P2Y12 inhibitor-based DAPT in Korean patients. A total of 4152 AMI patients who underwent percutaneous coronary intervention (PCI) in the Korea Acute Myocardial Infarction Registry were analyzed retrospectively. ⋯ However, the Thrombolysis in Myocardial Infarction (TIMI) major or minor bleeding rates were significantly lower in the TAT group compared with the potent DAPT group at 2 years (6.4% vs. 3.6%, p = 0.006). In Korean AMI patients undergoing PCI, TAT with cilostazol was associated with lower bleeding than the potent P2Y12 inhibitor-based DAPT without increased ischemic risk. These results could provide a rationale for the use of TAT in East Asian AMI patients.
