Comparing Ticagrelor with Low-dose Aspirin to Regular Aspirin for Heart Patients

Safety and Efficacy of Ticagrelor With Low-dose Aspirin Versus Regular Aspirin in Patients With Acute Coronary Syndrome at High-risk for Ischemia After Percutaneous Coronary Intervention: A Randomized Controlled Study

Phase 4 Interventional Fu Wai Hospital, Beijing, China · NCT04240834

This study is testing whether Ticagrelor with low-dose Aspirin is safer and more effective than Ticagrelor with regular-dose Aspirin for heart patients at high risk after a procedure to open blocked arteries.

What this trial studies

This study aims to evaluate the safety and effectiveness of Ticagrelor combined with low-dose Aspirin versus standard dual anti-platelet therapy in patients with acute coronary syndrome (ACS) who are at high risk for ischemic events following percutaneous coronary intervention (PCI). A total of 1220 patients will be enrolled and randomly assigned to receive either Ticagrelor with low-dose Aspirin or Ticagrelor with regular-dose Aspirin for a duration of 12 months. The primary goal is to assess the impact on major adverse cardiac and cerebral events, while secondary objectives include evaluating bleeding events, platelet function inhibition, and medication adherence. This research seeks to provide new insights into anti-platelet protocols for high-risk ACS patients.

Who should consider this trial

Good fit: Ideal candidates are patients with acute coronary syndrome at high risk for ischemic events who have undergone successful PCI with at least one drug-eluting stent.

Not a fit: Patients who do not have acute coronary syndrome or those who are not at high risk for ischemic events may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved treatment protocols that reduce the risk of ischemic events in high-risk heart patients.

How similar studies have performed: Other studies have shown promising results with similar anti-platelet approaches, suggesting potential for success in this trial.
