| Abstract | 「要旨」201Tl運動負荷心筋シンチグラフィにおけるTl灌流分布所見(Tl), 負荷心電図所見(ECG)と冠動脈造影所見の不一致例について詳細に比較検討した. 対象は283例であり, A群: Tl(+)・ECG(+), B群: Tl(+)・ECG(-), C群: Tl(-)・ECG(+), D群: Tl(-)・ECG(-)に分類した. Tlは視覚的診断によった. A群でも3%に正常冠動脈症例, D群でも38%に冠動脈狭窄症例(CAD)を認めた. B, C群では, 61%, 73%にCADを認めた. 正常冠動脈症例のTl偽陽性は, 正面像の下壁部(24%)またはLAO 45°像の中隔部(45%)のみの再分布が多かった. CAD症例群では, B群はSVD(62%), C群はTVD(26%), LMT(11%)の頻度が高かった. C, D群のTVD, LMT症例は, Tlの定量解析を併用することによりA, B群へと移行した(87%). LADのSVDのみについてみると, C群では90%以下の狭窄例が多く, 早期再分布がTl偽陰性に関与していることが示唆された. |

| Abstract | [Summary] Findings of thallium-201 perfusion (Tl) and exercise electrocardiography (ECG) at exercise thallium-201 scintigraphy was compared with coronary arteriographic findings (CAG) in 283 patients. We classified these cases into four groups by Tl and ECG; [A] Tl(+)・ECG(+),[B] Tl(+)・ECG(-), [C] Tl(-)・ECG(+), [D] Tl(-)・ECG (-).Redistribution of thallium-201 was evaluated by qualitative (visual) analysis. Three percent of group A consisted of the patients with normal coronary artery, and thirty-eight percent of group D consisted of the patients with coronary artery disease. On exercise thallium-201 scintigraphic imagings, most of patients with normal coronary artery showed redistribution of inferior (24%) and septum (45%). On exercise electrocardiographic findings, most of patients with normal coronary artery showed ST-segment depression in II, III, aVF, V5 and V6. In patients with coronary artery disease, single vessel disease in group B was larger than that in group C (62% vs.33%, p<0.05), and triple vessel disease and left main truncus disease in group C was larger than that in group B (37% vs.10%, p<0.05). On exercise thallium-201 scintigraphic imagings, most of false negative in patients with coronary artery disease changed to true positive by quantitative analysis. The patients with less than 90% coronary stenosis in group C was larger than that in group B (65% vs.100%). |
