Myocardial Protection by Brief Ischemia in Noncardiac Tissue

Abstract

Brief ischemia in "remote" organs protects myocardium against infarction as effectively as myocardial preconditioning. The mechanism of protection by MAO differs from that of CAO, because ganglion blockade abolished protection by MAO but not by CAO. The neurogenic pathway is activated during reperfusion after 15-minute MAO, because sustained MAO failed to produce cardioprotection.
