Abstract「要旨」 対角枝病変による急性心筋梗塞13例を検討した. ST上昇やQSの出現により入院時に急性心筋梗塞の診断が速やかになされたのは8例であった. 初回の冠動脈造影において, 責任冠動脈の同定が6例では困難であった. このうち3例では慢性期に再疎通が得られた後に責任冠動脈の同定が可能となった. 201Tl心筋SPECTに生じた梗塞領域は狭く, 前壁正中部に限局し, 中隔を含まないことを特徴とした. 慢性期左室造影において10例では前壁にdyskinesisを認め, 3例ではakinesisを認めた. このうち5例では前壁に心室瘤を認めた. 対角枝病変による心筋梗塞は, 梗塞範囲は狭くとも, 前壁にdyskinesisを生じる可能性が高いと考えられた. 本症の診断において201Tl心筋SPECTは部位診断にすぐれているので心電図や冠動脈造影法よりも本症の確定診断に有用なことが多いと考えられた.

Abstract[Summary] Characteristics of 201Tl myocardial SPECT and ventriculography were studied in 13 patients with acute diagonal branch myocardial infarction. Rest 201Tl myocardial SPECT and left ventriculography were underwent in chronic phase. In 5 patients ECG changes in acute phase were not definite. In 6 patients it was difficult to identify the obstructed coronary artery with coronary angiography in acute phase. Mean value of maximum CPK was 854 (458-1,774) U/l. It seemed to be difficult to diagnose acute diagonal branch myocardial infarction with ECG and/or coronary angiography. In all patients defects were noted on 201Tl SPECT. Defects were small and noted in the central anterior wall and not in the septum. In 2 patients defects were noted at apex. In left ventriculography dyskinetic motion was noted in 10 patients;one patient showed apical aneurysm and 3 patients showed anterior wall aneurysm. In 3 patients anterior wall showed akinesis. It was concluded that 201Tl myocardial SPECT were useful for detecting diagonal branch lesion. In case of diagonal branch myocardial infarction size of defects were small and defects were not noted in the septum, however aneurysmal motion was frequently noted.
