[Optimal conditions for preservation of isolated heart using creatine phosphate and vitamin E (an experimental study)].

Functional and structural safety of the myocardium following 6-hour preservation at 4-6 degrees C in ion-balanced cardioplegic solution alone or in combination with pharmacological corrective was evaluated in rats. Langendorff and Neely model of isolated heart perfusion was used. The addition of creatine phosphate in a conservation of 10 mM/l to the solution or donor pretreatment with 70 mg/kg vitamin E was found to potentiate the protective properties of the solution under deep hypothermia.
