Cardiac Catheterization Candidates Need to be Assessed by New Methods
"Our data show that up to two thirds of the patients undergoing invasive cardiac catheterization are found not have significant obstructive disease," says Manesh Patel, MD, a cardiologist with the Duke Heart Center. He's the lead author of the study published in the March 11 issue of the New England Journal of Medicine.
"We're spending a lot of energy and money to evaluate chest pain which often leads to cardiac catheterization, which, we now know, often finds that patients don't have significant obstructive disease," Patel says. "Our research shows that our methods for identifying patients at risk for obstructive disease need significant improvement."
More than 10 million Americans experience chest pain each year and many undergo testing like cardiac catheterization to determine if blocked arteries are the culprit. It's standard care for people who experience heart attack or unstable chest pain. The invasive test is not cheap, nor is it without some risk. But it allows doctors to visualize the vessels and arteries leading to the heart.
The main goal of cardiac catheterization is to identify the presence, location, and severity of coronary atherosclerosis, Patel says. "This is done with the understanding that some patients with severe obstruction may benefit from angioplasty or bypass surgery to relieve symptoms and to reduce the risk of a heart attack or death."
