Mono Antiplatelet and Colchicine Therapy

Phase 4

Registration Number
NCT04949516
Lead Sponsor
Wonkwang University Hospital
Brief Summary

The purpose of this study is to evaluate the efficacy and safety of aspirin-free, P2Y12 inhibitor single antiplatelet and colchicine treatment in patients with acute coronary syndrome treated with drug-eluting stents.

Detailed Description

After successful drug-eluting stent implantation for acute coronary syndrome, screening for study subject enrollment is performed. For those who submitted written informed consent, aspirin is stopped the day after the intervention, and colchicine 0.6mg once daily is started. The P2Y12 inhibitor, prasugrel or ticagrelor, for single antiplatelet therapy remains. For the duration of hospital stay, platelet reactivity using VerifyNow test and C-reactive protein are measured. Aspirin may be restarted at the discretion of the investigator based on results of the platelet function test. C-reactive protein is remeasured 30 days after the intervention. Clinical follow-up is performed 30 days and 90 days after the intervention.
