Abstract「I. はじめに」Coronary Care Unit(CCU), Intensive Care Unit(ICU)におけるballoon付きbedside catheterの使用が一般化し, 右心系の内圧や左心室拡張期末圧を反映する肺動脈楔入圧, 心拍出量の測定が比較的容易に行われている. しかし心室駆出率を始めとする心室諸容積に由来する正確な心機能指標の測定はCCUにおいて未だ日常化したとはいえない. 心臓エコー法が心室各容量の有力なmonitoringの方法として臨床応用が試みられているが心室駆出率等の測定に関しモデル化に起因する幾何学的計算から算出されなければならない不利がある. したがって, 心室壁運動が均一でないと予想される心筋虚血に由来するCCUの患者にとってモデル化に起因する誤差のないRI法がより有利である. しかしながら従来のscintillation cameraは, 比較的装置が大型になっており, bedsideで簡便にかつ迅速にくり返し心機能を測定するためには不適当である.

Abstract[Summary]We evaluated left ventricular (LV) function in congestive heart failure (CHF) under the treatment of a vasodilator, "Bucladesine Sodium" (BS) in Coronary Care Unit (CCU), where is specially protected for radioisotopes. 11 patients with CHF were examined before and during BS infusion using the nuclear probe, and LV ejection fraction, relative cardiac output (RCO) and max dV/dt were evaluated. 4 patients without cardiac failure were also measured by the nuclear probe as a normal control group. As results, LV ejection fraction, RCO and max dV/dt of CHF group were increased during BS infusion with decreasing blood pressure and pulmonary capillary wedge pressure. We conclude that BS is a useful vasodilator drug for the treatment of CHF, and also the non-imaging nuclear cardiac probe is helpful in assessing global ventricular function in CCU, where rapid estimations of the ventricular function is needed.
