Coronary artery disease in black African patients with diabetes: Insights from an Ivorian cardiac catheterization centre

Summary Background Coronary angiography data are scarce for black patients with diabetes. Aim To assess coronary angiography findings in patients with diabetes at the Abidjan Heart Institute. Methods This observational cross-sectional survey was conducted between 1 April 2010 and 31 December 2014. All patients admitted for known or suspected coronary artery disease who underwent coronary angiography were included in the Registre Prospectif des Actes de Cardiologie Interventionnelle de l’Institut de Cardiologie d’Abidjan . We analysed and compared coronary angiographical findings in patients with and without diabetes. Results Eighty patients with diabetes were compared with 353 patients without diabetes. Patients with diabetes were significantly older (58.7 ± 8.9 vs 52.1 ± 11.5 years; P P P  = 0.04, respectively). A higher proportion of patients with diabetes had an abnormal coronary angiogram (85.0% vs 67.7%; P  = 0.002). Coronary artery disease in patients with diabetes was predominantly characterized by multivessel disease ( P  60 years (hazard ratio 2.53, 95% confidence interval 1.59–4.04; P P  = 0.004) were associated with multivessel coronary artery disease. Conclusions In our study, diabetes emerged as a risk factor for multivessel coronary artery disease. Future studies should help to define the long-term prognosis of these patients, and to assess the benefits of myocardial revascularization procedures.
