Ticagrelor Versus Clopidogrel in East Asian Patients With Acute Coronary Syndrome and Diabetes Mellitus

BACKGROUND: It is still unknown whether diabetes mellitus (DM) affects the relative safety and efficacy of ticagrelor vs clopidogrel in East Asian patients with acute coronary syndrome (ACS).

Sumario:BACKGROUND: It is still unknown whether diabetes mellitus (DM) affects the relative safety and efficacy of ticagrelor vs clopidogrel in East Asian patients with acute coronary syndrome (ACS). OBJECTIVES: The authors sought to assess the safety and efficacy of ticagrelor vs clopidogrel according to the diabetic status of East Asian patients with ACS undergoing invasive management. METHODS: This prespecified analysis of the TICA KOREA (Clinically Significant Bleeding With Ticagrelor Versus Clopidogrel in Korean Patients With Acute Coronary Syndromes Intended for Invasive Management) trial included 800 Korean patients. The primary safety endpoint was clinically significant bleeding (PLATO [Platelet Inhibition and Clinical Outcomes] major or minor bleeding) at 12 months; the efficacy endpoint was major adverse cardiovascular events (cardiovascular death, myocardial infarction, and stroke). RESULTS: Of 800 patients, 216 (27.0%) had DM. The incidence of clinically significant bleeding within 12 months was significantly higher with ticagrelor than clopidogrel in the nondiabetic group (10.2% vs 4.3%; HR: 2.45; 95% CI: 1.27-4.70; P = 0.007) and tended to be higher in the diabetic group (13.8% vs 8.0%; HR: 1.87; 95% CI: 0.54-4.36; P = 0.15); there was no significant interaction between treatment-arm and DM (P for interaction = 0.64). The incidences of major adverse cardiovascular events were not significantly different after ticagrelor or clopidogrel both in the diabetic group (10.8% vs 6.0%; HR: 1.90; 95% CI: 0.71-5.07; P = 0.20) and in the nondiabetic group (8.5% vs 5.7%; HR: 1.51; 95% CI: 0.81-2.81; P = 0.19) without significant interaction (P-for-interaction = 0.71). CONCLUSIONS: In Korean ACS patients undergoing early invasive management, diabetes status did not affect the relative safety and efficacy of ticagrelor and clopidogrel.
