The origin of creatine kanase BB occurring in serum during aortocoronary bypass surgery.
The serum concentration of creatine kinase (CK)-BB during and after coronary bypass surgery was measured by a sensitive and highly specific radioimmunoassay technique. All patients showed a distinct and temporary increase in CK-BB concentration shortly after the start of operation. Our results indicate that this increase has no connection with damage of the heart or the brain. Most probably the BB isoenzyme is liberated mainly from the saphenous vein as a consequence of the surgical manipulations during the heart operation.
