Bouisset F, Ruidavets JB, Bongard V, et al. - Among 822 patients with stable coronary heart disease, researchers determined the influence of physical activity (PA) level on mortality at long term. Information on medical history was obtained. Participants underwent a standardized clinical examination. Fasting blood samples were also taken. Based on PA level, three tertiles of patients were individualized: 0.0-9 Metabolic Equivalent of Task (METs) hour per week (n = 267); 10-39.9 METs hour per week (n = 279); and ≥ 40 METs hour per week (n = 276). Participants were observed over a median duration of 14.6 years. Findings revealed an independent link between PA and long term vital prognosis. For a rise of 10 METs hour per week, a 5% total mortality reduction was observed.
