Optical coherence tomography findings in acute myocardial infarction patients with familial moyamoya disease.

UNLABELLED: It has been reported that patients with moyamoya disease have a high prevalence of coronary artery disease. On the other hand, the pathology of coronary artery disease is not fully understood. We were able to evaluate vascular properties using optical coherence tomography in a case of acute myocardial infarction that occurred in a relatively young woman with moyamoya disease. Previous reports using intravascular ultrasound have shown that coronary artery lesions in patients with moyamoya disease are caused by fibrous cell proliferation. Optical coherence tomography of our case showed a fibrous plaque rich in macrophages and a lipidic plaque. We believe that our case may lead to elucidation of the etiology of coronary artery disease in patients with moyamoya disease.

LEARNING OBJECTIVE: It is known that patients with moyamoya disease develop coronary artery disease at a young age, but the etiology has not been clarified. We used optical coherence tomography to evaluate the intravascular conditions of coronary artery disease patients with moyamoya disease. The lesions of coronary artery disease associated with moyamoya disease were mainly arteriosclerotic lesions rich in inflammation.
