Comparing single and dual antiplatelet therapies after heart surgery

Single Versus Dual Antiplatelet Therapy in Patients With Incomplete Revascularization After Coronary Artery Bypass Graft Surgery

Phase 3 Interventional Campus Bio-Medico University · NCT03789916

This study tests whether taking one or two types of blood-thinning medications after heart surgery helps patients who haven't had all their blood vessels fixed live longer and healthier.

What this trial studies

This study compares the effectiveness of single antiplatelet therapy (SAPT) versus dual antiplatelet therapy (DAPT) in patients who have undergone coronary artery bypass grafting (CABG) and have incomplete revascularization. Participants will be randomly assigned to receive either SAPT or DAPT before hospital discharge, with DAPT being administered for 12 months. The primary goal is to evaluate cardiac-related mortality five years after discharge.

Who should consider this trial

Good fit: Ideal candidates include patients who have undergone CABG and have been identified as having incomplete myocardial revascularization.

Not a fit: Patients with acute coronary syndrome within the last 12 months or those who cannot tolerate the medications involved will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into the optimal antiplatelet therapy for patients with incomplete revascularization, potentially improving long-term cardiac outcomes.

How similar studies have performed: Previous studies have explored antiplatelet therapies in similar contexts, but this specific comparison of SAPT versus DAPT in incomplete revascularization is relatively novel.
