About this trial
Monotherapy with a P2Y12 inhibitor after a minimum period of DAPT following percutaneous coronary intervention (PCI) is an emerging de-escalation antiplatelet strategy in recent years. However, the optimal timing for de-escalating DAPT in ACS patients undergoing PCI remains debated. The OPT-CAD score is a risk stratification tool derived from Chinese patients which has been demonstrated superior predictive capabilities for ischemic events and all-cause mortality than the GRACE score. Therefore, we hypothesize that the OPT-CAD score can be used to guide the timing of the DAPT de-escalation strategy to monotherapy with P2Y12 inhibitors for ACS patients, that is, low-risk patients could be de-escalated after 1 month, while high-risk patients could be de-escalated after 3 months, so as to achieve individualized antithrombotic therapy and maximize patient benefit.
