| Abstract | 「要旨」急性冠症候群では迅速な診断と治療が要求される. 緊急99mTc-tetrofosmin心筋シンチグラムが, 急性冠症候群の診断に有用であった症例を報告する. 症例1は66歳, 男性. 安静時の胸部不快感のため当科を受診した. 血液検査, 心電図, 心エコー図では異常はなかった. 緊急99mTc-tetrofosmin心筋シンチグラムでは, 前壁中隔から心尖部に中等度の集積低下所見があった. 冠動脈造影では左冠動脈主幹部に75%の狭窄病変を認め, 不安定狭心症と診断して, 緊急冠動脈バイパス術を行った. 症例2は61歳, 男性. 安静時の胸部不快感のため当科を受診した. 軽度の白血球増多と心電図ではV5-V6でT波の平低化を認めたが, 心エコー図での診断は困難であった. 緊急99mTc-tetrofosmin心筋シンチグラムでは, 後側壁に欠損を認めた. 冠動脈造影では左回旋枝AHA分類#14が完全閉塞で急性心筋梗塞と診断して, 同部位にPTCAを施行し, 再疎通を得た. |

| Abstract | Patients with acute coronary syndrome require accurate diagnosis and treatment. We found that emergency myocardial scintigraphy with 99mTc-tetrofosmin was useful for diagnosis in 2 patients with acute coronary syndrome. The first patient was a 66-year-old man, who was hospitalized with chest discomfort at rest. Blood tests, electrocardiography, and echocardiography revealed no unusual findings. Myocardial scintigraphy with 99mTc-tetrofosmin disclosed moderately reduced uptake extending from the anterior wall to the apex. Coronary arteriography revealed 75% stenosis of the left main trunk. He was diagnosed as having unstable angina pectoris and coronary bypass surgery was performed. The second patient was a 61-year-old man, who was hospitalized with chest discomfort. Slight leukocytosis and flat T waves in leads V5 and V6 on electrocardiogram were detected, but echocardiographic findings were not abnormal. Myocardial scintigraphy with 99mTc-tetrofosmin revealed a defect in the posterolateral wall. Coronary arteriography showed total obstruction of #14, and a diagnosis of acute myocardial infarction was established. PTCA of #14 was performed to achieve reperfusion. |
