[A case of asymptomatic myocardial infarction with multiple coronary aneurysms].
A 36-year-old man was hospitalized in December, 1990 because a small R wave was observed on his ECG in V1-3. The patient had suffered from a cold with fever for a month when he was a child. He had no symptoms or signs of myocardial infarction. The patient underwent selective right and left coronary angiography, which revealed specific coronary aneurysms in the left circumflex coronary artery and left anterior descending coronary artery. The aneurysm in the distal lesion of the left circumflex coronary artery was embolized by a thrombus and filled with many capillary arteries. The proximal lesion of the right coronary artery was slightly dilated. Good collateral flow from the right coronary artery to the left coronary artery was revealed by coronary angiography. Left ventriculograms were performed, and the anterior wall motion of the left ventricle was shown to the hypokinetic. A perfusion defect of the anterior wall of the left ventricle was revealed by Thallium-201 imaging with single photoemission computed tomography. Based on these findings, we diagnosed the patients' illness as old myocardial infarction caused by Kawasaki disease.(ABSTRACT TRUNCATED AT 250 WORDS)
