Objective To evaluate the protective effect of aminophylline on myocardium in the patients undergoing prothetic valve replacement operation of heart.Mothods Thirty patients undergoing prothetic valve replacement operation of heart were randomized to be treated either with aminophylline(n=15)or without aminophylline treatment(n=15). Aminophylline(5mg/kg)was injected intravenously at 15 minutes after induction of anesthesia.Cardiac troponin I(cTnI), cyclic adenosine monophosphate(cAMP),myeloperoxidase(MPO),ratio of aortic blood neutrophil count to coronary vein sinus blood neutrophil count,hemodynamics,time of aortic cress-clamping and other clinical data were recorded during the operation.Results There were no differences between the two groups in the major perioperative variables.Plasm cTnI concentration in both groups increased after off-clamping than that before CPB,however,it was lower in aminophylline group than that in control group.Concentration of cAMP in both groups after off-clamping was lower than that before CPB, however cAMP concentration in aminophylline group after off-clamping was higher than that in control group.Myocardial MPO activity and neutrophil count ratio after aortic off-clamping in aminophylline group was significantly lower than that in control group.Conclusion These results suggest that aminophylline is helpful to unprotection of myocardial and decreases the sequestration of neutrophil in myocardium.The mechanism of the protection may be related to the cAMP increased in myocardium.
