Discussing the diagnostic value of troponin in the acute myocardial infarction after cardiac surgery / 中国医师进修杂志

ABSTRACT

Objective To research the diagnostic value of troponin in the acute myocardial infarction after cardiac surgery.Methods The prospective study method was used.One hundred and thirtyfour patients of cardiac surgery were selected as observation group,36 patients of thoracic surgery were selected as control group.All the patients were given continuous electrocardiogram monitoring and measured troponin I,and the results were compared between the 2 groups.Results There was no statistical difference in the troponin I before anesthesia between the 2 groups (P ＞ 0.05).The troponin I 4 h after surgery was (13.010 ± 14.829) μg/L in observation group,(0.019 ± 0.007) μg/L in control group,there was statistical difference (P ＜ 0.05).One case of observation group happened the acute myocardial infarction after cardiac surgery,the troponin I was ＞ 40.000 μ g/L.Conclusions The troponin is obviously increased in the early stage in most patients of cardiac surgery,the false positive rate in diagnostic acute myocardial infarction is higher according to the troponin.For troponin,it will need the more evidence of evidence-based medicine to establish the diagnosis of acute myocardial infarction after cardiac surgery.
