Coronary angiographic findings in dilated cardiomyopathy in a sub-Saharan African population

Aim: To describe the coronary angiographic aspects observed in patients with dilated cardiomyopathies (DCM) in a sub-Saharan African country in order to improve their management. Methods: This was a cross-sectional study conducted from 1 January 2010 to 31 March 2016. All patients aged 18 years and older, presenting with DCM and admitted to Abidjan Heart Institute, who underwent coronary angiography were included. One hundred and eight patients were selected. We analysed and compared the coronary angiographic features observed. Results: The median age of our patients was 52 years (46–61). There was a male predominance (sex ratio = 3). Hypertension (53.7%) was the major cardiovascular risk factor found. Coronary angiography was abnormal in 37 patients (34.3%). Twenty-three patients (21.3%) had obstructive coronary artery disease (CAD). Patients with CAD were older than those with normal coronary arteries, but with no statistically significant difference (p = 0.06). Hypertension (p < 0.001) and diabetes (p = 0.0003) were statistically significantly more commonly reported in patients with CAD. Conclusion: Ischaemic heart disease is likely to be under-diagnosed in sub-Saharan Africa. A coronary angiographic assessment of patients receiving treatment for DCM, especially in the presence of cardiovascular risk factors, should help optimise their management and improve prognosis.
