[Previous sports history and risk of ischemic heart disease in a male professional group. The Paris Prospective Study I].
The association between individual history of sports activity and cardio-ischemic risk is studied in the population of the Paris Prospective Study I; 6,941 male subjects of the same professional group, aged 42 to 53 years, free of ischemic heart disease and nondiabetic were examined and questioned about their sports history. After a 6.5 year mean follow-up, 234 cases of ischemic heart disease were observed. The subjects practising sports (n = 918), have lower levels of blood pressure, cigarette consumption and corpulence than the other subjects and their relative risk of ischemic heart disease is equal to 0.67 (95% confidence interval: (0.43; 1.04). The ex-sportsmen (n = 4,469) have an ischemic heart disease incidence identical to that of subjects who never practised sports (n = 1,554) and differ only from the later in a slightly higher cigarette consumption. 3,472 subjects were re-examined 4 years after their entrance in the study; the 229 subjects who, during that period, stopped their sports activity have a systolic blood pressure level and tobacco consumption significantly higher at the end of the period but also at the initial exam, than those who continued (n = 337). These results suggest that, in this population, the subjects who keep up with some sports activity after 40 years of age, may have a reduced risk of ischemic heart disease, but they constitute a selected group for some risk factors. They illustrate the difficulty of interpreting observation results concerning the role of sports activity in the prevention of ischemic heart disease.
