Why it's done

Angioplasty is used to treat the buildup of fatty plaques in the heart's blood vessels. This buildup is a type of heart disease known as atherosclerosis.

Angioplasty may be a treatment option for you if:

• You have tried medications or lifestyle changes but these have not improved your heart health.
• You have chest pain (angina) that is worsening.
• You have a heart attack. Angioplasty can quickly open a blocked artery, reducing damage to your heart.

Angioplasty isn't for everyone. Depending on the extent of your heart disease and your overall health, your doctor may determine that coronary artery bypass surgery is a better option than angioplasty for you.

You may need coronary artery bypass surgery if:

• The main artery that brings blood to the left side of your heart is narrow
• Your heart muscle is weak
• You have diabetes and multiple severe blockages in your arteries

In coronary artery bypass surgery, the blocked part of your artery is bypassed using a healthy blood vessel from another part of your body.
