Management of major risk factors (smoking, hypercholesterolaemia, hypertension), in the context of secondary prevention, has an impact on recurrence and life expectancy. However, there is a delay between the publication of therapeutic trials and their diffusion within the medical community. The objective of this study was to evaluate the prevalence and management of the main risk factors in a sample of 500 men, with a mean age of 55.1 +/- 7.5 years, presenting with stable coronary artery disease. 11% of subjects had a family history of premature myocardial infarction. Smoking was frequent: 21% of smokers, 60% of ex-smokers. Hypercholesterolaemia (LDL-C3.4 mmole/l or treatment) was present in 82% of subjects. Only 45% of treated subjects had an LDL-C3.4 mmole/l. Hypertension (systolic blood pressureor = 140 mmHg or diastolic blood pressureor = 90 mmHg or treatment) was present in 61% of subjects. Only 33% of treated subjects were controlled. Non-insulin-dependent diabetes mellitus (blood glucoseor = 7.7 mmole/l or treatment) was present in 21% of subjects. Only 43% of treated subjects were controlled. Calculation of the distribution of major risk factors (smoking, pathological obesity, hypercholesterolaemia, hypertension, diabetes) showed that 90% of coronary patients presented at least two risk factors. Overall, the prevalence and management of risk factors in patients with stable coronary artery disease is far from optimal.
