Coronary Intervention Procedures

Consider a consultation if you have chest pain or pressure during activity, if a treadmill test, CT coronary angiography, or another test shows a narrowing, or if your doctor recommends catheterization. The doctor will review your symptoms, ECG, echocardiogram, and lab results before deciding whether a procedure is needed. Bring your previous test results and a list of your medications. Severe chest pain that does not ease with rest, especially with cold sweats or shortness of breath, needs emergency care right away.

PCI is performed through a catheter inserted from a blood vessel in the wrist or groin. The narrowed artery is opened with a balloon, and a stent is placed to keep it open, usually without general anesthesia. CABG is surgery, usually through an opening in the chest, that creates a new path for blood flow using a blood vessel from the chest, arm, or leg. Your care team chooses between them based on the number and location of blockages, heart function, and your overall health.

After a planned PCI, many patients go home within one to two days. Light activity such as easy walking is usually possible in the early days, while heavy lifting, driving, and strenuous exercise are generally postponed for one to two weeks or as your doctor advises. If PCI was done for a heart attack, recovery usually takes longer because the heart muscle needs closer monitoring. Cardiac rehabilitation is recommended to help you return to activity safely.

No. Stents are designed to stay permanently in the coronary artery. Over time, the lining of the artery grows over the stent surface. What needs watching is renarrowing at the stent site (restenosis) and new narrowing in other parts of the arteries. That is why regular checkups, taking medications as prescribed, quitting smoking, eating a healthy diet, and exercising regularly remain important after a stent is placed.

Doctors usually prescribe two antiplatelet medications together (DAPT): aspirin plus another drug such as clopidogrel, ticagrelor, or prasugrel, to prevent blood clots inside the stent. Your doctor decides how long, usually six to twelve months, followed by a single antiplatelet drug. You will usually also receive cholesterol-lowering medication and other drugs based on your condition. Do not stop these medications without talking to your doctor, because the risk of stent thrombosis can increase.

Yes, many patients can return to their usual activities and exercise after the initial recovery period. Regular exercise helps control blood pressure, cholesterol, and weight. In the early months, a medically supervised cardiac rehabilitation program helps determine a safe intensity. The type and amount of exercise depend on your heart function. As a general guide, about 150 minutes of moderate aerobic activity per week, such as brisk walking or cycling, is often recommended once your doctor approves.
