Abstract
The protective effect of intravenous mioflazinepretreatment was examined in intact dogs on cardiopulmonary bypass. The mechanical function of the left ventricle was measured by isovolumic pressurevolume relationships. Mioflazine alone had no inotropic effect. After one hour of normothermic (37°C) global ischaemia of the whole heart, no control hearts, pretreated with solvent, recovered sufficiently to support the animals circulation; this was not the case with animals pretreated with mioflazine, they all survived. After the 30-min reperfusion period, the solvent (control) pretreated hearts had a significantly lower (P=0.05) systolic and higher (P = 0.001) diastolic pressure-volume curve than those given mioflazine.
