Abstract

Idiopathic thrombocytopenic purpura (ITP) is an autoimmune disorder with a low platelet count characterized by premature platelet destruction and suppression of platelet production mediated by autoantibodies, which may predispose to bleeding. Although the prevalence of coronary artery disease (CAD) in ITP seems to be rare, their co-occurrence is not unusual. Patients with ITP have increased risks for thrombosis and atherosclerosis associated with hemostatic factors, endothelial damage, and the negative effects of steroid and immunoglobulin therapies. Thus, the coexistence of ITP and CAD presents complex problems requiring a balance between hemorrhagic risk and prevention of thrombosis. Here, the authors present two patients with ITP, who were revascularized in different ways for CAD. Although the optimal management of thrombocytopenic patients with CAD is uncertain, individualized treatment modalities can be useful in patients with ITP and CAD.
