This discovery suggests a novel treatment and prevention strategy for people at risk of heart disease, particularly as they age.
A recent study by researchers at Columbia University Medical Center found that only 16 percent of heart attack survivors meet the recommended amount of physical activity in the weeks following hospitalization. Clinician-supervised exercise programs have shown promise in encouraging more physical activity, but participation remains poor.
