Oxygenated crystalloid cardioplegia was found not to produce better
cardioprotection than blood or crystalloid cardioplegia, as assessed by
myoglobin and creatine kinase MB (CPK-MB) isoenzyme, in patients undergoing
coronary artery surgery. Myoglobin and CPK-MB levels were found to peak at
1 and 3 h, respectively, following release of the aortic cross-clamp. There
was a good correlation between peak myoglobin and CPK-MB levels. CPK-MB of
non-cardiac origin was found to represent a substantial proportion of total
CPK-MB 4 h after the release of the aortic cross-clamp.
