Researchers have found that attaining higher levels of physical fitness lowers the risk of having heart attacks and increases survival among those suffering from coronary artery disease, whether or not they have had a procedure to open up their blocked arteries. Lead author Rupert Hung, a medical student at the Johns Hopkins University School of Medicine, said that in their study, the patients who were most fit had a 75 percent lower risk of dying from any cause compared to those who were least fit.

He said that this was true regardless of whether the patient had previous stenting or bypass surgery to open up any blocked arteries. The study included information on more than 9,800 adults who had been diagnosed with coronary artery disease. All of the patients in the study had been referred by a physician to undergo a treadmill stress test and were followed for an average of 11 years to see whether they had a heart attack, had undergone a revascularization procedure to restore blood flow, or had died from any cause.

Co-investigator John W. McEvoy, M.B., B.Ch., a cardiology fellow at the Johns Hopkins University School of Medicine, said that they measured exercise capacity, expressed as metabolic equivalents, or METS, from the patients’ stress test results. He said that they found that each 1-MET increase in a person’s exercise capacity was associated with a 13 percent reduction in risk of death, regardless of whether they had previously had a procedure to open a blocked artery.

Senior author Michael Blaha, M.D., M.P.H., an assistant professor of medicine at the Johns Hopkins University School of Medicine and a cardiologist with the Johns Hopkins Ciccarone Center for the Prevention of Heart Disease, said that their results suggest that increasing physical fitness through cardiac rehabilitation programs and exercise may be an effective supplement to medications for preventing complications associated with coronary artery disease.

What is heart disease?

Heart disease or cardiovascular disease refers to a group of diseases that involve the heart and/ or blood vessels. Some of the more common ones are coronary heart disease, hypertension, stroke and peripheral arterial disease. While susceptibility to heart diseases increases with age, gender, high blood pressure, high cholesterol levels, stress there are many things we can do to improve our cardiovascular health. A low fat, high fibre diet with fruits and veggies, quitting smoking and giving up alcohol coupled with increased physical activity and less stress can go a long way in improving cardiovascular health.
