Among them, 20 patients were candidates of valve replacement and 18 PDA and pericarditis had their blood samples taken before operation,and 1,2,24 and 48 hours after closure of thorax for measurement of concentrations of CK、CK-MB and TnT,together with ECG recording. Results Of the 60 patients, concentrations of cTnT before operation were normal; 2 hours after aortic unclamping, the correlation coefficient between cTnT and aortic clamping was r = 0.873( P＜0.01), the regression analysis showed Y = 0. 019X-0. 026. Of the 20 patients, ECG showed the myocardium was ischemic; CK、CK-MB and cTnT all rose significantly, reaching the peak after closure of thorax. Of the 18 patients, the ECG and cTnT before operation and after closure of thorax were normal; except 2 patients with pericarditis.
