Cardaic CT Coronary Angiography Screening of Coronary Artery Disease in Diabetic Patients Presented with Low to Intermediate Risk Chest Pain

Background: Coronary artery disease (CAD) is the leading cause of death in patients with diabetes mellitus (DM). Eearly detection and management of CAD can decrease morbidity and mortality in such high risk patients. Methods: 200 patients, 140 (70%) were males and 60 were females with mean age of 57±6 years presented with diabetes mellitus (DM) and have no past history of CAD. Patients presented to emergency room (ER) with low to intermediate risk chest pain. All patients were examined with CCTA. Patients with evidence of acute coronary syndrome were excluded. Results: The study included 200 patients, 140 (70%) were males and 60 patients were females with mean age of 57±6 years. The average Duration of diabetes mellitus was 7.7±7 years. 136 patients (68%) of the study patients had significant CAD that required interventions. The distribution of CAD in the study group according to coronary artery calcium score (CACS) was as follows: 85 patients with CACS 0, 15 patients with CACS 1, 50 patients with CACS 2, 32 patients with CACS 3, and 18 patients with CACS 4. Conclusion: About 68% of diabetic patients presented to the ER with low to intermediate risk chest pain were found to have significant CAD that required intervention. CCTA may be a suitable tool for screening of diabetic patients with chest pain presented to ER with non acute coronray syndrome symptoms aiming to reduce mortality and morbidity. Aim of the Work: To evaluate the role of coronary cardiac CT angiography (CCTA) in detecting the incidence of coronary artery disease in diabetic patients presented to emergency room (ER) with low to intermediate risk chest pain.
