| Abstract | 「要旨」 急性心筋梗塞36例 (平均年齢59歳) を対象として, 心電図から得られるQRSスコア (Palmeri ら) , 60-3× (QRSスコア) の心電図駆出率 (ECG-EF) を99mTc心室造影法で求められた左室駆出率 (RI-EF) , および201Tl心筋シンチグラフィによる総心筋灌流指数 (TMPI) と比較検討した. その結果, ECG-EFとRI-EFはr=0.784 (p<0.01) とかなり密接な正相関関係が認あられた. 梗塞巣の大きさを反映するTMPIとEF (ECGおよびRI) とも密な正相関が示され, 梗塞巣が大きくなるにつれ, 左室機能の低下することが示唆された. 以上より, ECG-EFは梗塞巣の大きさと左室機能をベッドサイドで把握するのに有用な指標であることが明らかにされた. なお, 肺野への201Tl蓄積と右室描出の意義についても検討した. |

| Abstract | [Summary] Left ventricular function and infarct size were evaluated noninvasively by 12 lead electrocardiography (ECG) , Tl-201 imaging (TLI) and ECG gated radionuclide ventriculography (RNV) examined from 5 to 14 days after the initial attack in 36 patients with acute transmural myocardial infarction. Ages ranged from 32 to 77 years with a mean of 60. The subjects were divided into 2 groups according to the site of infarct : anterior and inferior. Parameters obtained were left ventricular ejection fraction (EF) examined by RNV, QRS score described by Palmeri et al. total myocardial perfusion index (TMPI) , lung uptake of Tl-201 (LU) on TLI. Significant negative correlation was obtained between EF and QRS score (r=-0.784, p<0.01) , better in patients with inferior MI than those with anterior. Also significant relationship was noted between TMPI and QRS score (r=0.636, p<0.01) . LU had a specificity of 93% and a sensitivity of 71% for predicting EF<30% and 79% and 86% respectively for TMPI<30. These data suggest that left ventricular function and infarct size will be detected by QRS score. LU was thought to be a fairly good sign predicting decreased EF (<30%) and massive infarct. |
