SEATTLE -- Men recovering from a heart attack who are at the highest risk of a second attack and thus would benefit most from conscientious participation in an exercise program are the least likely to do so, a University at Buffalo study has found.
Results of the study, presented here today (June 4, 1999) at the annual meeting of the American College of Sports Medicine, showed that heart attack survivors who were least likely to take part in a prescribed exercise rehabilitation program tended to be overweight, have high cholesterol and triglyceride levels and smoke tobacco.
"The dropout rate in cardiac rehabilitation is a huge problem," said Joan Dorn, Ph.D., assistant professor of social and preventive medicine in the UB School of Medicine and Biomedical Sciences and lead author on the study. "It is important to find out who is likely to drop out and how we can target them, so we can find ways to keep them involved.
"We found that the people who were at the most risk were the ones who attended least. Not only were these men in trouble already because of their cardiac risk factors, they compounded the risk by not participating regularly in the exercise program."
The research involved 308 of the 651 participants in the National Exercise and Heart Disease Project (NEHDP), a three-year, multicenter, randomized, clinical trial conducted in the U.S. from 1976-79. John P. Naughton, M.D., UB professor of medicine and former dean of the UB medical school, directed the trial.
Prescribing exercise after a heart attack was considered revolutionary
25 years ago. The NEHDP trial was designed to determine if a structured
exercise program could improve long-term survival. Participants in this study,
all men between the ages of 30 and 64, were randomly assigned to take part in a
structured cardiac-rehabilitation exercise program. This "treatment" group
first exercised for eight weeks in a laboratory setting and then
