Angioplasty is a procedure to relieve angina symptoms and thus improve your quality of life. By improving the blood flow to the heart muscle, an angioplasty can result in a more active and better quality of life, with less or no angina and less requirement for medication. However, it's wise to still make and maintain healthy lifestyle changes to help prevent a recurrence.
Occasionally, an angioplasty is performed as an emergency procedure to try to improve blood flow during a heart attack, or if you are experiencing unstable angina. Your cardiologist will discuss whether an angioplasty can help you, on the basis on your symptoms and results of other tests. Of these, the most important test is a coronary angiogram.
