What measurement means for angioplasty
Angioplasty is a procedure used to treat patients with diseased vessels that supply blood to the heart (coronary arteries).
The coronary arteries carry oxygen and nutrient-rich blood to the heart muscles. They can become narrowed or blocked due to build-ups of fat and cholesterol. During this procedure, a balloon is placed in the coronary artery then inflated. The balloon pushes blockages out of the way and allows more blood to flow through. Angioplasty may be used to prevent a heart attack, or to treat chest pain or other heart problems caused by the blockages.
Although angioplasty is relatively safe, people who have this surgery do have some risk for complications:
- Infection at the surgical site
- Ruptured artery
- Heart attack and stroke
How to understand Proficiency Ratings
Hospitals performing 400 or more angioplasty procedures have achieved proficiency – this can be a sign of high-quality care. Hospitals performing less than 10 procedures may only do so on an emergency basis and their ratings are not included in this report.
How to understand Mortality Ratings
A high mortality rate may not be due to medical errors. Some hospitals may experience a greater number of deaths because they see more sick patients. Our mortality rate information is shown as a comparison between a hospital’s actual mortality rate and the rate expected for that hospital. A rate that is the “Same” or “Better” than expected can be a sign of high-quality care.
