| 摘 要： | 目的观察急性心肌梗死(AMI)患者入院前后血清肌钙蛋白I(cTnI),心肌肌酸激酶同工酶MB(CK-MB)测定值的变化。探讨cTnI对早期诊断AMI的价值。方法对50例AMI患者和50例健康人血清进行cTnI和CK—MB的检测。结果 AMI后3h内cTnI阳性检出率94．0％,明显高于CK-MB24．0％,AM15d后cTnI阳性84．0％,而CK-MB仅为6．0％。结论血清cTnI能早期确切诊断AMI,具有较宽的诊断窗,是急性心肌梗死早期诊断较敏感和特异的血清标志物。

| Abstract: | Objective To investigate the early diagnostic value and significance of cardiac troponin I (cTnI) and CK-MB in acute myocardial infarction (AMI).Methods Serum from 50 patients with coronary heart disease (AMI) and 50 healthy were examined for cTnI and CK-MB. Results In the 3h after AMI, the positive rates of cTnI 94.0% were significantly higher than CK-MB.24.0%, in the 5 day after AMI, the positive rates were 84.0% for cTnI and CK-MB were 6.0%.Conclusion The serum level of cTnI can closely reflect of myocardial dagmage in AMI. It provides a early diagnostic window. Serum level of cTnI is a marker high sensitivity and specificity for AMI and can aid in the early diagnosis of AMI. |
