Few and controversial findings exist on the effect of sedentary behaviour and physical activity after myocardial infarction (MI). Here a well-conducted prospective community-based cohort study including 101,510 Chinese adults, in service or retired employees, demonstrated that the combination of sedentary behaviour (>4 hours per day sitting) and physical inactivity (practising< 20 minutes of physical activity once per week) led to an increased risk of all-cause mortality. However, sedentary individuals only, although engaging in moderate to vigorous activity (MVPA), also still remained at higher mortality risk than the reference group. It was previously shown that MVPA alone did not protect also against the heart failure and mortality after non-fatal MI.
