ABSTRACT
ObjectiveTo investigate the myocardial protection on cardiac valve replacement surgery with creatine phosphate of myocardial GIK (GIK) in order to reduce the surgical risk and improving the efficacy.Methods126 cases were unergone surgical treatment of heart valve disease,whose cardiac function on admission wereⅢor Ⅳ. 126 patients were randomly divided into two groups. Cardiopulmonary bypass time, aortic cross clamp time, postoperative myocardial injury markers ( CK-MB, cTNI) changes, arrhythmias, heart function recovery, length of stay and mortality rate and other indicators were compared between the two groups. ResultsThe age, gender, body mass,heart disease and surgery combined data were not statistically significant between the two groups( all P ＞0. 05). The cardiopulmonary bypass time, aortic cross clamp time and mortality had no significant differences between the two groups( all P ＞ 0.05 ). The CK-MB( 21.36± 9.21 ) U/L and cTNI(0.83 ± 0. 35 ) ng/ml of creatine phosphate group were significantly lower than those of the control group. The incidence of arrhythmia in phosphocreatine group (37. 1％ ) was significantly lower than ordinary group (57.8 ％ ) ( X2 ＝ 5. 418, P ＜ 0. 05 ). ConclusionThe application of creatine phosphate GIK before valve replacement surgery could effectively reduce reperfusion injury after myocardial ischemia,myocardial protection,and significantly reduce the incidence of arrhythmia and improve heart function in patients.
