Angioplasty is a procedure to open narrowed or blocked blood vessels that supply blood to the heart. These blood vessels are called the coronary arteries.
A coronary artery stent is a small, metal mesh tube that expands inside a coronary artery. A stent is often placed during or immediately after angioplasty. It helps prevent the artery from closing up again. A drug-eluting stent has medicine embedded in it that helps prevent the artery from closing in the long term.
A stent is a tiny tube placed into a hollow structure in your body. This structure can be an artery, a blood vessel, or something such as the tube t...
Before the angioplasty procedure begins, you will receive some pain medicine. You may also be given medicine that relaxes you, and blood-thinning medicines to prevent a blood clot from forming.
You will lie on a padded table. Your doctor will insert a flexible tube (catheter) through a surgical cut into an artery. Sometimes the catheter will be placed in your arm or wrist, or in your upper leg (groin) area. You will be awake during the procedure.
The doctor will use live x-ray pictures to carefully guide the catheter up into your heart and arteries. Dye will be injected into your body to highlight blood flow through the arteries. This helps the doctor see any blockages in the blood vessels that lead to your heart.
A guide wire is moved into and across the blockage. A balloon catheter is pushed over the guide wire and into the blockage. The balloon on the end is blown up (inflated). This opens the blocked vessel and restores proper blood flow to the heart.
A wire mesh tube (stent) may then be placed in this blocked area. The stent is inserted along with the balloon catheter. It expands when the balloon is inflated. The stent is left there to help keep the artery open.
The stent may be coated with a drug (called a drug-eluting stent). This type of stent may lower the chance of the artery closing back up in the future. Currently, drug-eluting stents are used only for certain people.
Arteries can become narrowed or blocked by deposits called plaque. Plaque is made up of fat and cholesterol that builds up on the inside of artery walls. This condition is called hardening of the arteries (atherosclerosis).
Hardening of the arteries
Hardening of the arteries, also called atherosclerosis, occurs when fat, cholesterol, and other substances build up in the walls of arteries. These ...
The average hospital stay is 2 days or less. Some people may not even have to stay overnight in the hospital.
In general, people who have angioplasty are able to walk around within a few hours after the procedure depending on how the procedure went and where the catheter was placed. Complete recovery takes a week or less. You will be given information how to care for yourself after angioplasty.

You had angioplasty when you were in the hospital. You may have also had a stent placed. Both of these were done to open narrowed or blocked corona...
For most people, angioplasty greatly improves blood flow through the coronary artery and the heart. It may help you avoid the need for coronary artery bypass surgery (CABG).
Angioplasty does not cure the cause of the blockage in your arteries. Your arteries may become narrow again.
Follow your heart-healthy diet, exercise, stop smoking (if you smoke), and reduce stress to lower your chances of having another blocked artery. Your provider may prescribe medicine to help lower your cholesterol.
