Changes in lifestyle plays an important role in recovery from heart disease . A doctor wants to encourage the patients to exercise more by organizing a free weekly exercise class and sending invitation cards to patients so that they would enroll if they like. After five years, the results show that the patients who came to the class had significantly better cardiovascular health than those who didn't come to the class.
