More Obese Patients Needing Angioplasty than Ever Before
Younger, morbidly obese patients undergoing percutaneous coronary intervention are also at greater risk for complications, study finds.
There’s no question that obesity greatly increases risk for developing heart disease. And with more Americans obese than ever before, it’s not surprising that the number of obese patients requiring angioplasty has nearly doubled since the ‘90s, according to a recent study.
Published in the Journal of the American College of Cardiology, this study looked at the proportion of morbidly obese patients undergoing percutaneous coronary intervention (also referred to as angioplasty)—a non-surgical procedure used to restore normal blood flow in patients with clogged arteries. Using a detailed registry, researchers identified more than 227,000 patients who underwent this procedure between 1998 and 2009 in the state of Michigan. Patients were divided into four categories based on their body mass index—lean, overweight, obese, and morbidly obese—and researchers compared outcomes based on weight.
After analysis, researchers found that the proportion of morbidly obese patients undergoing angioplasty nearly doubled between 1998 and 2009, increasing from 4.38% to 8.36% during this 11-year period. Compared to patients who were considered overweight, morbidly obese patients had significantly greater risk of complications and death from the procedure. And perhaps most concerning, morbidly obese patients were more likely to have diabetes and were much younger than the other groups (59.2 years old vs. 64.9 years old in the overweight group).
With an estimated one in 20 Americans morbidly obese, these findings are alarming. Despite morbidly obese patients being more than five years younger on average, they actually fared worse than older, overweight patients undergoing percutaneous coronary intervention. It’s possible that small changes to the procedure like the access site could make this procedure safer for morbidly obese patients, but the best way to improve outcomes is by helping patients achieve healthier weights. Morbid obesity (body mass index greater than 40) is a serious health condition that greatly increases risk for heart disease and other serious health issues, and can even interfere with basic physical functions, such as breathing or walking. Since morbidly obese patients have even greater risk for complications from heart procedures like angioplasty, reducing weight is the best way to prevent ever needing such procedures that can put a patient’s health at further risk.
