Being physically fit can help prevent heart attacks and increase survival in people with stable coronary artery disease, a new study finds.
This was true whether or not the patients underwent a procedure to open blocked heart arteries.
Researchers analyzed data from more than 9,800 adults with coronary artery disease who underwent a treadmill stress test. They were also followed for 11 years to see if they suffered a heart attack, had undergone a procedure to open blocked heart arteries or had died from any cause.
"We measured exercise capacity, expressed as metabolic equivalents, or METs, from the patients' stress test results," study co-investigator John McEvoy, a cardiology fellow at the Johns Hopkins University School of Medicine, said in a Hopkins news release. http://www.nlm.nih.gov/medlineplus/news/fullstory_142607.html
