Coronary angioplasty and stents

Coronary angioplasty (AN-jee-o-plas-tee), also called percutaneous coronary intervention, is a procedure used to open clogged heart arteries. Angioplasty involves temporarily inserting and inflating a tiny balloon where your artery is clogged to help widen the artery.

Angioplasty is often combined with the permanent placement of a small wire mesh tube called a stent to help prop the artery open and decrease its chance of narrowing again. Some stents are coated with medication to help keep your artery open (drug-eluting stents), while others are not (bare-metal stents).

Angioplasty can improve symptoms of blocked arteries, such as chest pain and shortness of breath. Angioplasty can also be used during a heart attack to quickly open a blocked artery and reduce the amount of damage to your heart.

Why it's done Risks How you prepare What you can expect Results

Angioplasty is used to treat a type of heart disease known as atherosclerosis. Atherosclerosis is the slow buildup of fatty plaques in your heart's blood vessels. Your doctor might suggest angioplasty as a treatment option when medications or lifestyle changes aren't enough to improve your heart health, or if you have a heart attack, worsening chest pain (angina) or other symptoms.

Angioplasty isn't for everyone. If the main artery that brings blood to the left side of your heart is narrow, if your heart muscle is weak or if you have multiple diseased blood vessels, then coronary artery bypass surgery may be a better option than angioplasty. In coronary artery bypass surgery, the blocked part of your artery is bypassed using a blood vessel from another part of your body.

If you have diabetes and multiple blockages, your doctor may suggest coronary artery bypass surgery. The decision of angioplasty versus bypass surgery will depend on the extent of your heart disease and overall medical condition.
