Abstract「要旨」心カテーテル検査を施行しているうっ血性心不全症例(左室駆出分画LVEF≦35%)にて心プールシンチグラフィを施行, 右室駆出分画の臨床的意義について検討した. 対象は心筋梗塞53例および, 拡張型心筋症20例である. 心筋梗塞症例は, RVEF>46% (正常値-2標準偏差)を(A)群, RVEF≦46%を(B)群とすると, それぞれ37例, 16例であった. 再梗塞, 多枝病変の頻度は(A), (B)群にて不変であったが, (B)群にて肺動脈圧, 左室拡張末期圧の増加を認めた. (C)群の拡張型心筋症では(B)群と同様の圧データを有し, 左室拡張末期容積が増加した. またLVEFとトレッドミル試験による運動耐応能は全群にて相関しなかったが, RVEFとは良好な相関を示した. うっ血性心不全においてRVEFの低下は右室後負荷の増加に伴いより重篤な病態を反映し, かつ運動耐応能と一致することから本症の重症度評価に有用である.

Abstract[Summary] Recently, right and left ventricular ejection fraction (RVEF and LVEF) were accurately assessed by gated blood pool scan and these clinical parameters were applied to evaluate the pre and postoperative evaluation of ischemic, valvular and congenital heart disease. This study was under taken to investigate the clinical significance of right ventricular function in the case with congestive heart failure which had lower LVEF (<=35%). There were divided into three groups: (A) 37 cases of myocardial infarction with normal RVEF (RVEF>46%), (B) 16 cases of myocardial infarction with decreased RVEF (RVEF<=46%) and (C) 20 cases of dilated cardiomyopathy with decreased RVEF (RVEFL=46%). Group (B) had increased pulmonary artery pressure, and left ventricular end-diastolic pressure. The incidence of recurrent attack and multivessel disease were not different between group (A) and (B), however, the exercise tolerance was decreased in group (B), Group (C) had also decreased exercise tolerance. These data demonstrated that decreased RVEF in congestive heart failure had high risk sub-group, and RVEF correlated with exercise tolerance compared to LVEF.
