Reducing Stress Reduces Heart Disease

The usual routine for patients with heart disease is to lower
cholesterol and blood pressure, stop smoking, encourage exercise, give
various heart medications, and sometimes angioplasty or bypass
surgery. But doctors may soon add stress management and relaxation to
their attack on heart disease.

A new study of patients with heart disease found that relaxation,
taming hostility, and helping people change the way they look at
life’s challenges can reduce their risk of having further heart
problems by 75% compared to people given only usual medical care and
medications. Reducing stress proved even more beneficial than getting

In this study, 107 heart patients were randomly divided into three
groups. The control group of forty patients received usual medical
care. Another 34 engaged in a vigorous exercise program for 35 minutes
three times a week for 16 weeks in addition to their usual medical
care. And 33 patients along with their usual care from physicians also
participated in a stress management program that included: Weekly
group sessions, educational information on heart disease and stress,
and muscle relaxation practice and biofeedback. Patients were taught
skills to monitor automatic irrational thought patterns and to develop
alternative interpretations of situations and thought patterns. They
were also instructed how to recognize signs of stress and manage moods
such as anger and depression.

The patients’ medical records were tracked for the next two to five years for heart attacks, bypass surgery, and angioplasty. In the control group that received standard medical care, 30% had additional heart trouble compared to 21% in the exercise group (not significantly different from usual care). But the stress management group showed a dramatic difference– only 10% had further heart problems. This translates into roughly one-quarter the cardiac risk compared to those not receiving the additional psychological skill training. The stress management training also resulted in lower levels of psychological distress, less hostility, and fewer episodes of ischemic chest pain. If a new drug produced the same 75% reduction in cardiac risk as stress management, it would be headlines and rapidly prescribed by physicians. Until this becomes standard of care, patients may have to seek out their own opportunities to learn stress management as part of their treatment.
