Abstract
Kawasaki disease (KD) is a systemic vasculitis of unknown cause which usually diagnosed in small children. However, KD can be present as coronary disease in adults even with no history of the disease in childhood. Here, we describe a case of KD in a 42-year-old male patient presented with severe retrosternal chest pain radiating to the left arm and provisionally diagnosed as acute coronary disease. Coronary artery ectasia and multiple aneurysms have been confirmed by coronary angiography that led to the diagnosis of KD. The patient was treated with Aspirin 81 mg orally once daily, Apixapan 5 mg orally twice daily, Rosuvastatin 40 mg orally once daily, Bisoprolol 5 mg orally once daily, and omeprazole 20 mg orally once daily. The patient was improved and discharged with anticoagulant drugs for life. Physicians should be aware that KD can be present as coronary disease in adults even with no history of the disease in childhood and has a limited treatment options due to unfavorable coronary anatomy.
