Stress Management Can Save Heart Patients' Lives
Patients recovering from heart attacks or other heart trouble could cut their risk of another heart incident by half if they incorporate stress management into their treatment, according to research from Duke Health.
The findings, published in the American Heart Association journal Circulation, are the result of a randomized clinical trial of 151 outpatients with coronary heart disease who were enrolled in cardiac rehabilitation due to heart blockages, chest pain, heart attacks or bypass surgery. They ranged in age from 36 to 84 years old.
About half of the patients participated in three months of traditional cardiac rehabilitation, which included exercise, a heart-healthy diet and drugs to manage cholesterol and high blood pressure.
The other half went to cardiac rehab and also attended weekly, 90-minute stress management groups that combined support, cognitive behavior therapy, muscle relaxation and other techniques to reduce stress. Patients were followed for an average of three years after rehab.
Thirty-three percent of patients who received only cardiac rehabilitation had another cardiovascular event such as a heart attack, bypass surgery, stroke, hospitalization for chest pain or death from any cause. By comparison, 18 percent of the patients who participated in stress-management training during their cardiac rehabilitation had subsequent cardiovascular trouble — about half the rate of the other group.
Both sets of patients who went to rehab fared better still than recovering heart patients who elected not to attend rehab; 47 percent of this group later died or had another cardiovascular incident, according to the article.
We have known for some time that participation in a supervised exercise program is beneficial in patients with coronary heart disease,” said Alan Hinderliter, M.D., cardiologist with UNC Health Care and co-investigator on the trial. “The results of this study suggest that stress management is also a very important element of a comprehensive cardiac rehabilitation program. The intervention was clearly helpful in reducing stress levels, but we need additional research to confirm the benefits of stress management in improving cardiovascular outcomes.”
Although death rates from heart disease have improved, it remains the No. 1 cause of death in the U.S. and is growing worldwide, according to the American Heart Association.
