Aspects of Coronary Angiography in Diabetic Patients at the CHU Mother and Child Luxembourg in Bamako

Introduction: Type 2 diabetes is on the increase in Africa as a result of the epidemiological transition. Cardiovascular complications, particularly ischemic complications, are common in diabetic patients. They are life-threatening. It is important to identify the angiographic appearance of the coronary arteries in diabetic patients in order to guide treatment. Objective: to identify the results of coronary angiography in diabetic patients. Patients and method: Descriptive, cross-sectional study with retrospective recruitment over a three-year period from September 2019 to August 2022. All diabetic patients who underwent coronary angiography at the CHU mother child Luxembourg in Bamako were included. Results: We enrolled 371 patients out of 985 during the study period, i.e. a hospital frequency rate of 37.66%. The mean age of the patients was 60.76 +/- 10.26 years, with extremes of 32 and 84 years. They were predominantly male, with a sex ratio of 1.45. The predominant functional signs were typical chest pain (39.4%), atypical chest pain (27.8%) and dyspnea (13.2%). The predominant risk factors were hypertension (74.7%), sedentary lifestyle (48.8%) and smoking (17.5%). The indications for coronary angiography were chronic coronary syndrome (55%) and acute coronary syndrome (45%). Coronary angiography was pathological in 78.4% of patients, with tritruncular lesions in 38% and bi-truncal lesions in 21%. Lesions were located on the common trunk in 5.4%, on the anterior interventricular in 59.8%, on the right coronary in 51.8% and on the circumflex in 47.4%. Conclusion: Ischemic heart disease is common in diabetic patients with tri- and bi-truncular lesions.
