The association between a positive emotional state of mind and lower mortality in patients with ischemic heart disease is mediated by exercise, according to the results of a new study .
Patients with higher levels of positive affect, which reflects a pleasurable response to the environment and typically includes feelings of happiness, joy, excitement, contentment and enthusiasm, had a 42% lower risk of all-cause mortality at five years and were 50% more likely to participate in an exercise program than those with lower levels of positive affect.
In an adjusted regression model, there was no significant association between positive affect, as measured using the global mood scale (GMS), and cardiac-related hospitalizations. Ischemic heart disease patients with higher levels of positive affect on the GMS had a significant 42% lower risk of all-cause mortality at five years. In addition, these happier patients were also 48% more likely to exercise.
