The study:A series of 50 consecutive patients who underwent coronary angiography at Tajoura Cardiac Centre for various indications were retrospectively studied. The method: Data obtained from various clinical and laboratory parameters including Coronary risk factors were statistically analysed. The results: 70% were males and the mean age was 51.6years. Coronary risk factors including hypertension and or diabetes and or smoking were found in 82% of cases. 18% had no risk factor. Difference in prevalence of hypertension and diabetes between male and female sub – groups was not significant but smoking and All-risk were significantly higher in males (94% VS, 53%, P< 0.001) Resting ECG, Exercise ECG and Echocardiography were performed in 100%, 22% and 96% of cases respectively. Exercise - ECG had specificity of 33% and sensitivity of 83%. All patients had coronary angiography with diagnostic indication in 62% versus prognostic in 38%.72% had angiographically evident(positive)stenotic coronary artery disease(CAD),26%had no CAD,2% had congenital coronary artery fistula. The incidence of CAD was 83% among patients with risk factor (s) compared to only 22% among those without (P<0.001). For male versus female sub-groups, CAD incidence was (82% VS,53%,P<0.015) Ventricular fibrillation occuried in 4% which was successfully reverted. Conclusion: Hypertension, diabetes mellitus and smoking were significant risk factors for CAD. Men had significantly higher prevalence of CAD than women because of increased (mainly smoking) coronary risk factors. Exercise ECG had low specificity and reasonable sensitivity for CAD. Apart from non- fatal arrhytmia no serious complications encountered during coronary angiography indicating that it is safe procedure in the management of Libyan patients suspected to have CAD.
