Background

It is still unknown whether diabetes mellitus (DM) affects the relative safety and efficacy of ticagrelor and clopidogrel in East Asian patients with ACS. We investigated the safety and efficacy of ticagrelor versus clopidogrel according to the diabetic status of patients with acute coronary syndrome (ACS) intended for invasive management.

Methods

This prespecified analysis of the TICAKOREA (Ticagrelor Versus Clopidogrel in Asian/Korean Patients with ACS Intended for Invasive Management) trial included 800 Korean patients hospitalized for ACS randomized to ticagrelor or clopidogrel. The primary safety end point was clinically significant bleeding (PLATO major or minor bleeding) at 12 months; the efficacy end point was a major adverse cardiovascular event (MACE; a composite of cardiovascular death, myocardial infarction, or stroke).

Results

Of 800 patients, 216 (27.0%) had DM. The incidence of primary safety end point within 12 months was higher with ticagrelor than clopidogrel in patients with DM (13.8% vs. 8.0%; hazard ratio [HR], 1.87; 95% confidence interval [CI], 0.54-4.36) and in those without DM (10.2% vs. 4.3%; HR 2.45; 95% CI, 1.27-4.70); there was no significant interaction between treatment arm and diabetic status (P-for-interaction = 0.64). The incidence of MACE within 12 months also tended to be higher with ticagrelor than with clopidogrel in patients with DM (10.8% vs. 6.0%; HR, 1.90; 95% CI, 0.71-5.07) and in those without DM (8.5% vs. 5.7%; HR 1.51; 95% CI, 0.81-2.81) without any significant interaction between treatment arm and diabetic status (P-for-interaction = 0.71).

Conclusion

In Korean ACS patients undergoing early invasive management, diabetes status did not affect the relative safety and efficacy of ticagrelor and clopidogrel.
