简要总结
The goal of this clinical trial is to compare short-term Triple Antithrombotic Therapy (DAPT + Rivaroxaban) followed by DAPT with standard DAPT in selected ACS patients with high ischemic risk. The main questions it aims to answer are:
- Whether the intervention is effective in reducing ischemic events
- Whether the intervention is safe from increasing bleeding events, especially severe or fatal ones
Participants will be randomized to receive standard DAPT therapy for the entire study duration or low-dose rivaroxaban+DAPT for 3 months, followed by standard DAPT for the rest of the study duration. Patients enrolled should complete 5 follow-ups in the form of clinic visit or telephone call.
