| Abstract | 「要旨」安静時再分布心筋シンチグラムにて, 逆再分布現象を呈したstunned myocardiumの1例を経験した. 症例は58歳男性. 胸痛を主訴として入院. 心電図でI, II, III, aVl, aVf, V2〜V6でgiant negative T波, 心エコーでapexから前壁にかけてのakinesisを認めた. 入院3日目に施行した安静時再分布心筋シンチグラムでは, 心尖部から前壁にかけての灌流欠損と, 再分布像で同部位の拡大所見を呈した. 慢性期に施行した冠動脈造影では有意狭窄を認めず, 左室造影では壁運動異常も改善していた. 再度施行した心筋シンチグラムでも欠損の縮小を認めた. 本例は急性期安静時再分布心筋シンチグラムで逆再分布現象を呈したという点で, 心筋viabilityの判定に苦慮したstunned myocardiumの1例である. 本所見の機序は発症早期の冠血流の再疎通が考えられた. |

| Abstract | [Summary] A58-year-old man was admitted to our hospital because of chest pain. Electrocardiogram showed giant negative T waves in leads I, II, III, aVl, aVf and V2 through V6. Echocardiogram showed anterior wall motion abnormality. Rest-redistribution thallium scan obtained 3 days after admission revealed reverse redistribution in antero-apical area. Coronary angiogram showed no significant stenotic lesions and left ventriculogram in chronic stage showed improvement of wall motion abnormality. Repeat thallium scan in chronic stage showed disappearance of perfusion defect in apical area. It was difficult to diagnose myocardial viability in our case with stunned myocardium because rest-redistribution thallium scan showed reverse redistribution. As the mechanism of this finding, early coronary recanalization in acute stage of the event was suspected. |
