Summary

This trial is testing whether the drug ticagrelor is more effective than clopidogrel in reducing the risk of thrombotic events (blood clots) in patients who are also taking oral anticoagulants (blood thinners). A total of 63 patients will be enrolled and given either ticagrelor or clopidogrel. The trial will assess the pharmacodynamic effects of both drugs to determine which is more effective.

Who is the study for?
Adults over 18 who've had successful PCI and are on dual antiplatelet therapy (aspirin plus a P2Y12 inhibitor) and an oral anticoagulant for any reason. They must not be in other drug studies, have major bleeding issues, severe liver disease, recent strokes, life-threatening non-cardiovascular diseases, end-stage renal disease on dialysis, or allergies to the study drugs.
What is being tested?
The trial is testing how well two blood-thinning medications—Ticagrelor and Clopidogrel—work in patients with coronary artery disease who also need oral anticoagulation after PCI. It aims to see if one is better at preventing platelets from clumping together using a scoring system called ABCD-GENE.
What are the potential side effects?
Possible side effects include bleeding problems since both Ticagrelor and Clopidogrel prevent blood clotting. There may also be risks of bruising easily, shortness of breath or allergic reactions. The exact side effects will vary between individuals.
