Taking Blood Thinners After Percutaneous Coronary Intervention (PCI)

Percutaneous coronary intervention (PCI) involves angioplasty and often stenting. After this procedure, there is a chance that a blood clot will form at the blockage site. A blood clot can also form on a stent, if you have one. Your doctor will prescribe medicine to help prevent this. Over time, the artery may also become blocked again. By monitoring your symptoms, you help your doctor detect problems before they become too serious.

Preventing blood clots

To help prevent blood clots, you will need to take medicine, usually aspirin, every day for a long period of time. You may also need a second medicine called a P2Y12 inhibitor. An example of this medicine is clopidogrel. Take these medicines exactly as directed. Doing so lowers your risk for heart attack and even death. Your healthcare provider can tell you how long these medicines will be needed. Don't stop taking them without talking with your heart doctor first.
