Precision Antiplatelet Therapy After Percutaneous Coronary Intervention

The purpose of this research study is to see how use of genetic testing to help doctors with choosing blood thinning medication after a heart procedure called an angioplasty (also called percutaneous coronary intervention or PCI) affects your risk of having a heart attack, stroke, death or bleeding. Some doctors use genetic testing to help decide which blood thinner to prescribe for a patient. By doing the study, the investigators will be able to look at clinical outcomes (heart attacks, stroke, death, bleeding) after genetic testing and prescribing of blood thinning medications for patients with different backgrounds and medical histories. They will also look for new genes that affect how blood thinners work.
