目的对比分析床旁快速肌钙蛋白T(c Tn T)检测在急性胸痛患者的检测结果,分析c Tn T急性心肌梗死的诊断价值。方法选择2013年6月至2014年6月急诊胸痛患者共310例为研究对象,就诊时均进行床旁快速肌钙蛋白T检测,依据病情轻重分组,对比分析入组患者的临床资料,比较进行床旁快速肌钙蛋白T检测及应用于进行心肌梗死的诊断价值。结果入组310例患者检测c Tn T、肌酸激酶同工酶(CK-MB)、肌酸激酶(CK)、天门冬氨酸氨基转移酶(AST)在对急性心肌梗死诊断方面,c Tn T的敏感度和特异度优于CK-MB、CK、AST,且当c Tn T检测水平为0.112 ng/ml时,敏感度和特异度最优。结论床旁快速检测肌钙蛋白T对急性心肌梗死诊断敏感性和特异性优于心肌酶学检测,当c TNT为0.112 ng/ml时敏感度和特异度最优,对于急性胸痛患者应常规进行检测。
Objective To comparatively analyze the detection results of bedside fast troponin T (c Tn T) in patients with acute chest pain and analyze the diagnostic value of c Tn T acute myocardial infarction. Methods A total of 310 emergency chest pain patients from June 2013 to June 2014 were selected as the study subjects. Bedside rapid troponin T examination was performed at the time of diagnosis. The patients were divided into groups according to their severity. The clinical data of the patients were compared and compared Bedside rapid troponin T detection and its application in the diagnosis of myocardial infarction. Results Tn T, CK-MB, CK, AST were detected in 310 patients. In the diagnosis of acute myocardial infarction, c Tn The sensitivity and specificity of T were better than those of CK-MB, CK and AST, and the sensitivity and specificity were the best when the detection level of cTn T was 0.112 ng / ml. Conclusion The detection of troponin T at bedside is more sensitive and specific than myocardial enzymology. When c TNT is 0.112 ng / ml, it has the best sensitivity and specificity, and should be routinely performed in patients with acute chest pain Detection.
