Result
All cases (N=22),myocardial injury detected in 20 (91%): before operation cTn values are normal,after operation 20 (91%) above URL. Before operation 1 (4.5%) CK-MB value above URL, after operation 4 (18%) values above URL.
There were statistically significant differences in the comparisons of serum cTn and MYO level before the operation and after operation: cTn mean of differences 3.599 (95% CI, 1.566 to 5.632), P=0.0014; MYO Mean of differences 2.139 (95% CI, 0.8034 to 3.475), P=0.0032. There were no statistically significant differences in the comparisons of serum CK-MB and CK level before the operation and after operation: CK-MB mean of differences 0.1550 (95% CI, -0.01239 to 0.3224), P=0.0677; CK mean of differences 1.080 (95% CI, -0.4072 to 2.568), P=0.1458.
