Both Inactivity, Strenuous Activity Up Mortality Risk
the MPR take:
Physical inactivity is a known risk factor for cardiovascular disease, but can high levels of physical activity also increase cardiovascular mortality risk? New research in the journal Heart assessed 1,038 patients with stable coronary heart disease (CHD) and their levels of physical activity over a 10-year span. While those with the lowest physical activity levels had a four-fold risk of cardiovascular and all-cause mortality, those who had the highest levels of physical activity also had a two-fold risk of cardiovascular mortality (2.36, 95% CI 1.05–5.34). Moderate exercise appears to be most beneficial for cardiovascular health.
Objective To study the association of self-reported physical activity level with prognosis in a cohort of patients with coronary heart disease (CHD), with a special focus on the dose-response relationship with different levels of physical activity.Methods Data were drawn from a prospective cohort of 1038 subjects with stable CHD in which frequency of strenuous leisure time physical activity was assessed repeatedly over 10 years of follow-up.
