The purpose of this study was to determine the role of ventricular size or contractility in the effectiveness of dynamic cardiac compression in terms of the pressure-volume relationship and myocardial oxygen consumption. In 10 isolated cross-circulat

BACKGROUND We hypothesized that the effect of pimobendan (UD-CG 115 BS) to increase calcium sensitivity of contractile protein might result in less myocardial oxygen consumption (VO2) in comparison with dobutamine when they enhance ventricular contra

We studied the effects of cardiac hypothermia on myocardial oxygen consumption of a fibrillating ventricle and evaluated whether myocardial oxygen consumption of a fibrillating ventricle in hypothermia can be accounted for by new mechanical indexes:

We have recently proposed a mechanical index, equivalent pressure-volume (PV) area (ePVA), as a measure of the total mechanical energy during ventricular fibrillation (VF). ePVA, an analogue of the PV area (PVA) of a beating heart, is the area surrou

We propose new indexes to evaluate the effects of ventricular inotropism and lusitropism on stroke volume. The end-systolic pressure-volume relationship (ESPVR) or its slope (Emax) has been employed to assess ventricular inotropism. The end-diastolic

We studied whether ventricular fibrillation depresses ventricular contractility in a blood-perfused heart. In 12 excised, cross-circulated dog hearts, we measured left ventricular pressure and myocardial oxygen consumption at a middle left ventricula

The effects of DPI 201-106 (a novel, cyclic AMP-independent positive inotropic agent with Ca(2+)-sensitizing and Na(+)-channel agonistic mechanisms) on myocardial mechanics and energetics were assessed in the excised cross-circulated dog left ventric

We attempted to find cardiac mechanical parameters to account for myocardial O2 consumption (VO2) during ventricular fibrillation (VF). We fully utilized the concept of pressure-volume (P-V) area (PVA), which is equivalent to the total mechanical ene

Recent studies have shown that myocardial oxygen consumption does not proportionally decrease with the deterioration of contractile function in stunned myocardium. To investigate this disproportion, we studied the end-systolic pressure-volume relatio

To elucidate the mechanism of acute contractile failure induced by adriamycin, the intracellular concentrations of free calcium ([Ca2+]i) and energy-related phosphate compounds were determined in isolated ferret hearts. The time-averaged [Ca2+]i was
