Objective To compare the myocardial protective effect between off pump coronary artery bypass(OPCAB) and on pump coronary artery bypass in the aged. Methods Four five patients were randomly divided into 3 groups:off pump coronary artery bypass (n=15),tepid blood cardioplegia group(n=15) and cold blood cardioplegia group (n=15).There was no statistical difference in heart function,sex,age and lesion of coronary artery .Venous blood samples were taken for determineing the serum concentration of creatine kinase MB isoenzyme(CK MB),troponin I perioperatively and the clinical situations were observed postoperatively. Results CK MB,troponin I release in beating group during and after bypass was lower than that in on pump groups( P
