Abstract | The isolated isovolumic rat heart was used as a model of cardiac hypoxia. Force of cardiac contraction and cardiac cyclic nucleotide levels (cyclic GMP and cyclic AMP) were monitored in hearts subjected to hypoxia for 5 min and allowed to recover by reoxygenation. Hearts were obtained from both control animals and animals pretreated with methylprednisolone at 18 hr and 1 hr prior to sacrifice. Myocardial levels of cyclic GMP which were significantly (p <0.05) elevated above control during all periods of hypoxia were found to be lower when hearts were pretreated with methylprednisolone prior to hypoxic exposure. Hearts of animals pretreated with methylprednisolone also demonstrated better recovery during reoxygenation than did control hearts. These studies suggest that methylprednisolone may be beneficial in the prevention of myocardial failure following hypoxia via a modulation in myocardial cyclic GMP content. |
