| Abstract | 「要旨」心筋梗塞後患者における運動負荷心電図ST変化の臨床的意義を明らかにするため, 発症後1〜3か月の患者93例に運動負荷201Tl心筋single photon emission computed tomography (SPECT) を施行し, SPECT所見を中心に冠動脈造影, 左室造影所見とも対比して検討した. 運動によるST低下出現頻度は罹患冠動脈数と共に増加し, ST低下例の90%にSPECTで一過性虚血が認められた. ST上昇は全体の31%に認められ, 全例前壁側に梗塞を有し, その93% (26/28) に左室造影上高度壁運動異常が認められ, またSPECTでは広範な前壁側の持続欠損と内腔拡大が特徴的所見であった. 以上より, ST低下は一過性虚血, ST上昇は前壁側の広範な梗塞に起因する高度壁運動異常を示す所見と考えられた. |

| Abstract | [Summary] To explain the clinical significance of stress (st) -induced ST-segment (ST) changes postinfarction, 93 patients with previous myocardial infarction (MI) were performed st-201Tl myocardial single photon emission computed tomography (SPECT) and compared ST changes with SPECT, coronary arteriographic and left ventriculographic findings. 30 out of 93 cases (32%) had ST depression, 20 (21.5%) had ST elevation, 9 (10%) had both ST depression and elevation and remaining 34 (36.5%) had no significant ST changes. In single vessel disease, ST depression were noted in 29% (12/42) , while in multivessel disease, 53% (27/51) . 35 out of 39 cases (90%) with ST depression had transient perfusion defect but no apparent relation was noted between location of ST depression on ECG and region of transient perfusion defect in SPECT. All of 28 cases with ST elevation were noted in anterior MI cases, and 26 out of these showed severe LV wall motion abnormality in contrast left ventriculography and broad anterior permanent defect in SPECT. Only 15 cases (54%) showed slight redistribution. Thus, we conclude that in patients with previous MI, st-induced ST depress ion seems to reflect myocardial ischemia and ST elevation possibly related abnormal LV wall motion. |
