Literature Review and Case Report on ST-Segment Elevation Myocardial Infarction in Kawasaki Disease

Kawasaki disease (KD), primarily affecting children but occasionally adults, is characterized by fever and acute inflammation. It can lead to serious complications like coronary artery aneurysms, heart failure, and arrhythmias, with cardiovascular issues being the primary cause of morbidity and mortality. A 48-year-old man presented with acute chest pain, sweating, and vomiting. Tests showed elevated liver enzymes, erythrocyte sedimentation rate (ESR), and troponin. Electrocardiography (ECG) indicated ST-segment elevation, and echocardiography revealed a dilated left atrium, reduced left ventricular function, and akinesis in multiple segments. Coronary angiography found total occlusion and thrombus in the mid-left anterior descending artery, with ectasia in the right coronary artery and minor ectasia in the left circumflex artery. The patient was diagnosed with ST-segment elevation myocardial infarction due to KD and was treated with dual antiplatelet therapy and statins. This case highlights the importance of diagnosing KD in adults to prevent severe complications.
