You might feel pressure in the area where the catheter is inserted. You may also feel some mild discomfort when the balloon is inflated and your artery is stretched, but typically you shouldn't feel any sharp pain during the procedure. When placing a coronary artery stent, your doctor will find a blockage in your heart's arteries A.
A balloon on the tip of the catheter is inflated to widen the blocked artery, and a metal mesh stent is placed B. After the stent is placed, the artery is held open by the stent, which allows blood to flow through the previously blocked artery C. Most people who have angioplasty also have a stent placed in their blocked artery during the same procedure. A stent, which looks like a tiny coil of wire mesh, supports the walls of your artery and helps prevent it from re-narrowing after angioplasty.
Most stents implanted during an angioplasty are drug coated. The medication in the stent is slowly released to help prevent future plaque buildup and the re-narrowing of the blood vessel. After your stent placement, your doctor will prescribe medications, such as aspirin, clopidogrel Plavix , ticagrelor Brilinta or prasugrel Effient , to reduce the chance of blood clots forming on the stent. If you had a nonemergency procedure, you'll probably remain at the hospital overnight while your heart is monitored and your medications are adjusted.
You generally should be able to return to work or your normal routine the week after angioplasty. When you return home, drink plenty of fluids to help flush your body of the contrast dye. Avoid strenuous exercise and lifting heavy objects for at least a day afterward. Ask your doctor or nurse about other restrictions in activity. It's important that you closely follow your doctor's recommendations about your treatment with blood-thinning medications — aspirin and clopidogrel Plavix , prasugrel Effient or similar medications.
Most people who have undergone angioplasty with or without stent placement will need to take aspirin indefinitely. Those who have had stent placement will need a blood-thinning medication, such as clopidogrel, for six months to a year. If you have any questions or if you need any other type of surgery, talk to your cardiologist before stopping any of these medications. Coronary angioplasty greatly increases blood flow through the previously narrowed or blocked coronary artery.
Chest pain generally should decrease. You may be better able to exercise. Having angioplasty and stenting doesn't mean your heart disease goes away. You'll need to continue healthy lifestyle habits and take medications as prescribed by your doctor. If you have symptoms similar to those you had before coronary angioplasty, such as chest pain or shortness of breath, contact your doctor.
If you have chest pain at rest or pain that doesn't respond to nitroglycerin, call or emergency medical help. Successful angioplasty also means you might not have to undergo coronary artery bypass surgery, a more invasive procedure that requires a longer recovery time.
