NOAC Therapy Guided by PARIS Risk Score and D-dimer in Patients With ACS After PCI

Phase 4

Recruiting

• Conditions: Percutaneous Coronary Intervention; Acute Coronary Syndrome; Coronary Artery Disease
• Interventions: Drug: Aspirin + Clopidogrel + Rivaroxaban; Drug: Aspirin + Clopidogrel

• Registration Number: NCT05638867
• Lead Sponsor: China National Center for Cardiovascular Diseases

Brief Summary

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.
