Résumé
192 personnel of the medical staff of 11 departments of Kasr El-Eini Faculty of Medicine, Cairo University [144 males and 48 females] aged 29 to 70 years, were divided into two groups. Group [1], 121 persons [111 males and 10 females] aged 30 to 70 years [mean 43.2] were submitted to clinical and laboratory investigations for risk and underlying factors of coronary heart disease. Group [2], 71 persons [33 males and 38 females] aged 29 to 61 years [mean 38.2] were submitted to measurement of blood pressure, interview for life style and activities especially those which may be associated with risk exposure to coronary heart disease. Out of the 121 group [1] subjects, 96 cases have completed all history, clinical and laboratory investigations. The statistical data in the present study revealed that according to existing coronary artery risk and disease, they were classified into a risk 82/96 [95.6%] which were further subdivided into low risk in one case, intermediate risk in 10/96 [10.6%], and high risk in 7/96 [14.6%]. There was a significant difference between group [1] and [2] for at risk subjects and coronary artery disease. This is due to detection of some risk factors by laboratory investigations which change the whole picture of some risk and disease. Hence, periodic health appraisal with the subject may be unaware, yet contribute to progressively increasing risk of developing coronary heart disease and for diagnosis of coronary heart disease cases in the early inapparent stage
