Psychosocial variables moderate the relationship between leisure time physical activity and mortality among myocardial infarction survivors

Leisure time physical activity (LTPA) is inversely related to mortality risk among patients with a history of myocardial infarction (MI). In a paper just published in BMC Cardiovascular Disorders -with Dr. Rony Oosterom-Calo as first author- we explored if heart failure (HF) status and psychosocial variables moderate this association in a prospective cohort study among MI survivors.
LTPA was inversely associated with mortality. HF did not, but psychosocial variables did, moderate the association. Among the higher active patients, patients with a high level of depression had a lower mortality risk in comparison to those with a low level, and patients with a low level of social support had a lower mortality risk in comparison to those with a high level of social support.
