Doctors usually use angioplasty to
- Reduce chest pain caused due to blockages in the coronary arteries - Angioplasty can treat certain types of angina.
- Limits damage to the heart during or after heart attack - Angioplasty is an emergency treatment done in this case.
Angioplasty does not cure coronary artery disease. To prevent plaque blockages, a person needs to take prescribed medications, eat healthy foods and do regular exercise.
