Myocardial protection with methylprednisolone. Evaluation of viability of hearts subjected to warm ischemia before transplantation
LH Toledo-Pereyra and FM Jara
Methylprednisolone was given at different intervals before warm ischemia of
the heart (37 degrees C. for 60 minutes), and viability of these hearts was
evaluated after transplantation into the abdomen of another dog. Animals
were divided into four groups: Group 1 received no methylprednisolone:
Groups II, III, and IV received 30 mg. of methylprednisolone per kilogram
10 minutes, 60 minutes, and 120 minutes before warm ischemia. In all
parameters measured, the animals of Group IV performed better than the
other groups. It is concluded that methylprednisolone, when given 2 hours
before warm ischemia, exerts a protective effect on the ischemic
myocardium.
