Comparison of the effects of increased myocardial oxygen consumption and adenosine on the coronary microvascular resistance.
The purposes of this study were to determine if coronary dilation secondary to an increase in myocardial oxygen consumption (MVO2) affects the microcirculation in a homogeneous or heterogeneous manner and to determine if comparable degrees of coronary dilation produced by increasing MVO2 or exogenous (intravenous adenosine) or endogenous (intravenous dipyridamole) adenosine have similar effects...
متن کاملStudies on digitalis. XVI. Effects on myocardial oxygen consumption.
The effects of cardiac glycosides on myocardial oxygen consumption (MVo2) have been investigated extensively, and although the results of these studies have not been entirely uniform, it is now generally considered that these agents are "the only drugs which increase the force of contraction of the myocardium without at the same time increasing oxygen consumption" (1). The finding in previous i...

متن کاملCanine myocardial adenosine and lactate production, oxygen consumption, and coronary blood flow during stellate ganglia stimulation.
The vasodilator adenosine is produced continuously by the normal dog myocardium. However, the relation of adenosine production to increased cardiac metabolism requires clarification. This study tested the hypothesis that increased myocardial Oi demand promotes increased adenosine production to match coronary blood flow (CBF) to metabolic requirements. Increased adenosine production, therefore, ...
متن کاملHemodynamic dependence of myocardial oxygen consumption indexes.
We tested the afterload and contractile state dependency of three indexes of myocardial oxygen consumption (MVO2): total energy requirement (Et), pressure work index (PWI), and pressure-volume area (PVA). MVO2 was measured in seven isolated canine hearts at four or five different end-diastolic volumes at each of three settings of afterload resistance and with the hearts contracting isovolumical...
