Background: Ischemic cardiomyopathy can be reversible after revascularization hence the interest of making systematic coronary angiography that remain an invasive procedure.
Aim: To detect epidemiological, clinical and paraclinical differences between idiopathic and ischemic dilated cardiomyopathy to identify predictors of coronary artery disease and to evaluate the interest of making systematic coronary angiography within the etiological check-up of dilated cardiomyopathy.
Methods: We performed a retrospective study in patients with dilated cardiomyopathy in whom coronary angiography allowed to distinguish the ischemic cardiomyopathy group from that of idiopathic cardiomyopathy.
