The aim of the study was to evaluate 1) whether the ability of leucocytes to produce oxygen radicals was increased by ischemia and 2) if ibuprofen pretreatment could influence leucocyte oxygen radical production, hemodynamic function, and myocardial oxygen consumption during acute ischemic myocardial failure. We studied two groups of anesthetized dogs (control and ibuprofen-treated), both subjected to coronary embolization with polystyrene microspheres (diameter 50 microns). The embolization procedure was ended when left-ventricular end-diastolic pressure in both groups exceeded 20 mm Hg. Before and after induction of ischemia leucocytes were isolated and stimulated with opsonized zymosan, and oxygen radical production was measured using the luminol-dependent chemiluminescence technique. Significant increase occurred in oxygen radical production (from 10.9 +/- 2.2 to 16.3 +/- 2.3 x 10(5) counts x 10(6) cells-1 x 60 min-1) 90 min after failure in the control group, whereas in ibuprofen-pretreated dogs oxygen radical production was unchanged. Hemodynamic registrations and myocardial oxygen consumption 90 min after failure were, however, not significantly different in control dogs and dogs pretreated with ibuprofen. Thus, in the present study, within the first 90 min of acute ischemic failure, a decrease in the ability of leucocytes to produce oxygen radicals was not related to significant changes in myocardial function.
