目的:探讨心肌肌钙蛋白Ⅰ(cardiac troponin Ⅰ,简称cTnI)对溶栓治疗急性心肌梗死(AMI)时的检测意义。方法:观察比较42例急性心肌梗死(AMI)患者和30例无Q波心肌梗死患者的cTnI和心肌酶谱。结果:AMI患者的阳性率分别为cTnI 78.6%、CK 54.8%、CK-MB 59.5%。结论:AMI患者胸痛后6h之内血清cTnI的敏感性最高,对早期诊断、及时溶栓治疗AMI有重大临床价值。
Objective: To investigate the significance of cardiac troponin Ⅰ (cTnI) in the treatment of acute myocardial infarction (AMI) by thrombolytic therapy. Methods: The cTnI and myocardial enzymes of 42 patients with acute myocardial infarction (AMI) and 30 patients without Q wave myocardial infarction were observed and compared. Results: The positive rates of AMI patients were cTnI 78.6%, CK 54.8% and CK-MB 59.5% respectively. Conclusion: The sensitivity of serum cTnI is the highest within 6 hours after chest pain in patients with AMI. It has great clinical value for the early diagnosis and timely thrombolytic therapy of AMI.
