| Abstract | 「要旨」心筋梗塞症14例について, 左室を8区画に分割し, 各区画の壁運動と心筋灌流状態を比較検討した. 局所壁運動は心プール平衡時マルチゲート法を用い, 各区画の壁運動量と位相を定量的に算出する方法を考案して解析し, 次の5型に分類した. N : 正常, 1 : 壁運動量の著明低下, 2 : 壁運動量の低下, 3 : 位相のみ異常, 4 : 壁運動量低下に位相異常を伴う. 心筋灌流状態は運動負荷201Tl心筋シンチグラムのearly imageを用い, circumferential profile法により, 正常灌流, 低灌流, 欠損の3型に分類した. われわれの壁運動解析法は心筋灌流低下部位の95%を壁運動異常として指摘し得, 有用な方法と考えられた. 低灌流, 欠損と虚血の程度が強くなるにつれ, 4型の壁運動を示す割合が大であった. しかし, 心筋灌流が正常な部位にも高率に (39%) , 何らかの壁運動異常を認めた. 以上より, 局所の壁運動と心筋灌流には関連性が認められたが, 壁運動異常の有無・型は単に虚血の有無・程度のみでは規定されないと考えられた. |

| Abstract | Summary We evaluated the relationship between the regional wall motion and regional myocardial ischemia in fourteen patients with myocardial infarction by dividing the left ventricular image into eight sections. We analyzed regional wall motion by a new method of gated blood pool scan analysis and we divided it into five types : N : normal, 1 : remarkably low wall movement, 2 : low wall movement, 3 : phase abnormality and 4 : low wall movement with phase abnormality. We analyzed myocardial perfusion by the circumferential profile method of exercise 201Tl myocardial scintigram and classified myocardial perfusion as normal perfusion, hypoperfusion and defect. Our new method of regional wall motion analysis was shown to be useful because it could detect 95% of the areas of myocardial hypoperfusion and defect. Furthermore, regional wall motion abnormality was observed in normal perfusion areas at a high rate too. The areas of low wall movement with phase abnormality were observed more frequently with increasing severity of ischemia and the areas with defect image were closely correlated with a high degree of phase abnormality. We concluded that the type of regional wall motion with myocardial infarction is related to myocardial perfusion but regional wall motion abnormality cannot be explained on the basis of presence or absence of ischemia or the degree of its severity. |
