Comparing antiplatelet therapies in patients with low platelet counts

Official title: Dual Antiplatelet Therapy (DAPT) in Patients With Baseline Thrombocytopenia

Run by Methodist Health System · NCT06223607 · Data updated 2026-11-12

This study is testing which antiplatelet medication, clopidogrel or ticagrelor, works better for people with low platelet counts who are having heart procedures to see which one helps prevent complications like bleeding or heart attacks.

Is this trial a fit for you?

Likely a good fit

Ideal candidates include adults aged 18 and older with a history of thrombocytopenia and who have undergone PCI with either drug-eluting or bare metal stents.

Probably not a fit

Patients who have died within 48 hours post-PCI or who received DAPT prior to cardiac catheterization may not benefit from this study.

What this trial studies

This observational study evaluates the effectiveness of dual antiplatelet therapy (DAPT) using clopidogrel versus ticagrelor in patients with chronic thrombocytopenia undergoing percutaneous coronary intervention (PCI). It aims to determine which medication better balances the risks of bleeding and ischemic events following the procedure. The study will analyze data from patients who received PCI with either drug-eluting stents or bare metal stents between April 2018 and July 2021, focusing on their platelet counts and outcomes post-intervention.

Why it matters

Potential benefit: If successful, this study could lead to improved management strategies for patients with thrombocytopenia undergoing PCI, potentially reducing bleeding complications.

How similar studies have gone: While there is limited data specifically addressing this patient population, studies on antiplatelet therapy in broader populations have shown varying outcomes, indicating that this approach may provide new insights.
