| Abstract | 「要旨」 心筋梗塞症例において多枝病変虚血(対側虚血)を検出することは, 予後および治療方針の決定に関して重要である. そこで, 81例の心筋梗塞症例を前壁梗塞群(ANT-MI)47例・下後壁梗塞群(INF-MI)34例に分類し, 201Tl負荷心筋シンチグラフィ(EX-Tl)を用い, 多枝病変虚血(対側虚血)の検出に関して検討した. その結果, 負荷心電図に比較して, EX-TlのPlanar(PL)・SPECTの視覚的診断のみにても対側虚血の検出率は良好であった(67% vs. 72%, 79%). PLとSPECTの視覚的診断を比較すると, 両群ともSPECTの検出率が良好であった(ANT-MI:77% vs. 83%, INF-MI:65% vs. 74%). SPECTによる視覚的診断と定量的診断を比較すると, 視覚的診断ではANT-MI:83%, INF-MI:74%であったが, 定量的診断ではANT-MI:83%, INF-MI:79%と検出率は後者でやや良好な傾向があった. SPECTの視覚的診断と定量的診断を組み合わせると, 対側虚血の検出率はさらに上昇した(ANT-MI:87%, INF-MI:82%). 心筋梗塞症例において多枝病変虚血(対側虚血)を検出する場合, SPECTの定量解析を併用することが有用であろことが示された. |

| Abstract | [Summary] The detection of multivessel disease (MVD) in patients with myocardial infarction (MI) was performed using exercise myocardial scintigraphy with qualitative and quantitative analysis, to compare the diagnostic ability of planar (PL), planar+washout rate (PL+WR), SPECT, Bull's eye+WR (BE+WR) and SPECT+BE+WR. Forty seven patients of anterior MI (SVD:DVD:TVD=29:8:10) and thirty four patients of infero-posterior MI (SVD:DVD:TVD=16:8:10) were reviewed. SPECT was superior to PL to detect ischemia of RCA in patients with anterior MI (50% vs. 100%) and to detect ischemia of diagonal branch in patients with infero-posterior MI (0% vs. 83%). The detection of ischemia of LCX in patients with anterior MI revealed low sensitivity in both PL and SPECT. SPECT+BE+WR showed the highest diagnostic ability to detect MVD in patients with both anterior (87%) and infero-posterior MI (82%). We conclude that SPECT with qualitative and quantitative analysis is the most useful to detect MVD in patients with MI. |
