Résumé : The relationship between physical activity on and off the job, physical fitness and coronary artery disease was investigated in a prospective study involving 2 363 men, 40 to 55 years old. Sudden death and myocardial infarction occurred in 31 subjects during a 5-year follow-up. Preliminary data are reported. There was no significant correlation between quartiles of physical activity on and off the job and incidence of coronary events. Physical fitness was significantly inversely correlated with incidence of coronary events (p < 0.05) and was significantly lower in the 31 new cases (p < 0.03). Multivariate analysis showed that HDL-cholesterol, smoking and physical fitness significantly and independently discriminate between coronary prone patients and healthy subjects. We conclude that physical fitness is an independent, inverse risk indicator of new coronary events.
