| Abstract | 「要旨」201Tl運動負荷心筋シンチを回復期の急性心筋梗塞55例に行い, 急性期の冠動脈狭窄度および側副血行路が慢性期の心筋salvageに及ぼす影響を検討した. 冠動脈再開通が不成功であった(再開通後の冠動脈狭窄が100%)14例中, 側副血行路良好群では, 4例中3例がタリウム上完全欠損を認めなかったのに対し, 側副血行路不良群では10例中8例で完全欠損を認めた. 側副血行路不良群16例の中では75%以下に再開通しても6例で完全欠損を認めたのに対し, 側副血行路良好群では90%以下に狭窄が解除されれば全例完全欠損を残さなかった. 急性期冠動脈所見において, 再灌流前のforward flow(99%あるいは90%狭窄例)と良好な側副血行の発達(Rentrop分類2, 3度)のうちどちらかの因子があれば, 心筋salvage成功の可能性が高いと考えられた(p<0.05). |

| Abstract | [Summary]201Tl stress myocardial scintigraphy was performed in convalescent patients with acute myocardial infarction, to evaluate the influence of stenosis and collateral circulation of coronary artery in acute phase, on myocardial salvage in chronic phase. In 14 cases of unsuccessful coronary revascularization (complete occlusion), a complete defect of thallium imaging in chronic phase was seen in only one case of four cases with good collateral circulation, while eight of 10 cases with poor collateral circulation. In 16 cases of poor collateral circulation, six cases showed a complete defect, although the target vessel had improved to less than 75% of stenosis. However, in cases of good collateral circulation, no case showed a complete defect when the target vessel had improved to less than 75% of stenosis. The myocardial salvage is quite possible (p<0.05), when the coronary angiography in acute phase showed the forward flow (99% or 90% of stenosis) before coronary revascularization and/or good collateral circulation (Rentrop 2°or 3°). |
