Abstract:
Objective To investigate the change of serum cardiac troponin I(cTnI)following coronary artery bypass grafting.Methods 55 OPCABs and 55 cCABGs were performed.Serum cTnI were measured before operation(T1)and immediately after operation(T2)and 1d(T3),2d(T4),3d(T5),4d(T6),5d(T7),6d(T8),7d(T9),10d(T10),14d(T11).Results The serum cTnI level increased differently after OPCAB and cCABG and then returned to normal level gradually.The peak value of serum cTnI level in OPCAB was lower than that in cCABG.There were 9 cases on myocardial infarction,of which OPCAB 4 cases,cCABG 5 case,with serum cTnI level increasing;and there weren't death.Conclusion The serum cTnI in OPCAB and cCABG both increased and then decreased to normal level gradually.Measuring serum cTnI could diagnose myocardial injury and indicate prognosis.
