[Distribution of cardiovascular risk factors in a Tunisian cohort of 6901 coronary patients].

The Tunisian epidemiological data on cardiovascular disease in the hospital environment are scarce. The aim of this study was to evaluate the frequency of cardiovascular risk factors and their association in patients hospitalised for coronary disease in coronary care units at Rabta, Charles Nicolle, Habib Thameur and Military hospitals, Tunis, over the period 1994-1998. The clinical features of 6901 patients (75.7% men, 3760 myocardial infarction, 3141 unstable angina) on hospital admission were analysed. The prevalence of smoking, dyslipidemia, hypertension, diabetes and obesity was 86; 49.8; 33.9; 40.7 and 15.2% respectively in the men and 12.9; 52.4; 64.6; 53.4 and 29.8% respectively in women. With this risk factor profile Tunisia has to implement a national strategy of primary prevention and heart health promotion in addition to the efforts recently made in secondary prevention of some chronic disease such as hypertension, diabetes and smoking.
