[Clinical study of fructose 1,6-diphosphate on myocardial ischemia/reperfusion injuries].

Twenty ventricular septal defect patients who underwent cardiopulmonary bypass (CPB) were divided into 1,6-diphosphate group and controlled group (10 cases each). Blood samples were taken at pre- and post-cardiopulmonary bypass 30 min, 6 h, and 24 h to determine lactate dehydrogenase enzyme(LDH), creatine kinase enzyme(CK) and its isoenzyme(CK-MB) levels. We found that 1,6-diphosphate decreased the increasing levels of LDH, CK, and CK-MB after cardiopulmonary bypass. It is suggested that 1,6-diphosphate may attenuate myocardial ischemia/reperfusion injuries during cardiopulmonary bypass.
