| Abstract | 「要旨」1枝のみに狭窄を有する労作性狭心症20例および心筋梗塞22例の計42例を対象に運動負荷心筋シンチグラムを行い, defect部の欠損程度を定量評価し, その欠損程度を壁運動異常程度, 臨床所見と対比することにより, 欠損程度の臨床的意義について検討した. 欠損程度は正常部に対する相対的摂取率(relative activity:RA)で表した. 安静時壁運動異常のない狭心症20例においては18例に運動時に胸痛を認め, 運動時defect部のRAは77.5±4.59%で梗塞例の65.7±7.85%に比べて有意に高値を示した(P<0.05), 次に梗塞例ではhypokinesisのみを有する軽度壁運動障害例(12例)ではdefect部のRAは69.5±4.78%であり, 高度壁運動障害例の61.3±8.45%に比べて有意に高値を示した(p<0.01). 以上の結果よりdefect部の定量評価は虚血部と壊死部の鑑別の一助になると考えられた. |

| Abstract | [Summary]To clarify the significance of the quantitative analysis of the area of decreased activity in exercise thallium-201 myocardial imaging, 42 patients with one vessel disease (20 patients with angina pectoris without myocardial infarction, 22 patients with old myocardial infarction: MI) were evaluated by exercise thallium scan and compared with clinical findings and wall motion assessed by left ventriculography (LVG). Patients with MI were devided into two groups by LVG (Mild MI: MI with only hypokinesis on LVG, Severe MI: MI with akinesis or dyskinesis on LVG). The degree of defected area was expressed by the ratio of the counts of defected area to the normal area (Relative Activity: RA). RA of the area of decreased activity in patients with angina was higher than that of patients with MI (77.5 +- 4.59% vs. 65.7 +- 7.85%, p<0.05). RA of the area of decreased activity in patients with mild MI was higher than that of patients with severe MI (69.5 +- 4.78% vs. 61.3 +- 8.45%, p<0.01). The above results suggest that the regional thallium-201 uptake ratio in the scintigram may help to differentiate viable zones from necrotic ones and detect the degree of MI. |
