Abstract

The hypothesis that the ATP-sensitive potassium channel provides the link between change in coronary blood flow and myocardial oxygen demand was tested in 9 dogs instrumented to measure coronary flow and regional wall thickening in the basal state and at a high level of myocardial oxygen consumption produced by systemic infusion of phenylephrine and simultaneous atrial pacing at an elevated heart rate. Measurements were recorded before and after blockade of ATP-sensitive potassium channels with intracoronary glibenclamide (2 mumol/min). While glibenclamide reduced the absolute level of coronary flow in the basal state, the increase in flow due to increased metabolic demand was unchanged compared with control. Thus, activity of the ATP-sensitive potassium channel determines the set point from which adjustments of coronary flow in response to metabolic stimuli occur, but does not provide a link between changes in oxygen demand and changes in coronary flow.
