    The present study was carried out to clarify the mechanism of glucose metabolism in the pathologic myocardium devoid of coronary stenosis, we have used positron CT with use of F-FDG and we have measured quantitatively the amount of the glucose metabolism by Patlak method the following subjects involving 22 patients with cardiomyopathy, 4 patients with pressure-overload hypertrophy, 12 patients with valvular disease. We have discussed the result from the angle of myocardial oxygen consumption, myocardial oxygen supply, and hemodynamics. We can explain this case where glucose mechanism accentuated but devoid of coronary stenosis by the data proposed in this study i. e., the balance of myocardial oxygen consumption and myocardial oxygen supply. With regard to the mitral stenosis it has become undeniable that the case of accentuation of the glucose metabolism is attribution to the vibration of the ventricular wall caused by turbulent blood flow due to mitral stenosis.

    We evaluated the effect of milrinone (MIL) on venous return by constructing the right ventricular output curve and systemic venous return curve.
    In the open-chest dogs (n=12) anesthetized with intravenous pentobarbital, total spinal anesthesia was performed to eliminate the baroreflex. The dogs were divided into two groups, i.e. Non-MIL group (n=6) and MIL group (n=6) receiving an intravenous MIL (100μg/kg + 2.5,μg/kg/min ). We measured the mean circulatory pressure (MCP) and other hemodynamic parameters at the baseline (before blood volume change), immediately after blood letting (5ml/kg) and immediately after dextran injection (5ml/kg). Taking the right atrial pressure (RAP) on the abscissa and the cardiac output (CO) on the ordinate, we drew the right ventricular output curve. The systemic venous return curve was drawn by connecting the CO-RAP plot to the point of MCP on the abscissa. The slope of the systemic venous return curve represents the resistance to venous return (RVR).
    MIL shifted the right ventricular output curve to the left and upwards, and shifted the systemic venous return curve to the left (MCP being decreased) and rotated it clockwise (RVR being decreased). These results suggest that venous return was increased by decreasing RVR and by increasing the right ventricular pump function.
