Conditions
Brief summary
The aim of the SPARTA trial is to clarify the impact of extending DAPT beyond 1 year after XINSORB BRS implantation by investigating the balance of risk and benefit in a broad population of treated patients.
Interventions
DRUGClopidogrel
Study subjects diagnosed as stable, unstable ischemic coronary disease or myocardial infarction planning to undergo percutaneous coronary intervention (PCI) and no contradiction to prolonged DAPT are eligible for this trial. All subjects will provide written informed consent to participate. Subjects will be enrolled into the study before or within 24 hours after the index procedure. Subjects will be randomized to either discontinue P2Y12 inhibitor (clopidogrel or ticagrelor) (12 months total) or receive P2Y12 inhibitor for an additional 24 months (36 months total). Aspirin will be maintained in the entire study and can be replaced by cilostazol or indobufen if subjects are intolerant. Dosage of antiplatelet drugs will be according to local standard of practice. Subjects will be treated with XINSORB BRS only.
