目的探讨心肌三联检测卡在急性心肌梗死中的诊断价值。方法用心肌三联检测卡定性测定41例AMI患者和21例健康体检者血清中的Mb,CTnI,CK-MB和用日立7020型全自动生化分析仪定量测定CK-MB(CK-MB≥25IU/ml为阳性)。结果用心肌三联检测卡定性测定AMI患者的Mb,CtnI,CK-MB早期的阳性率分别为87.80%,51.00%,21.95%;健康体检者阳性率为4.76%;用日立7020型全自动生化分析仪测定CK-MB的阳性率为26.83%,健康体检者阳性率为4.76%。心肌三联检测卡和日立7020型全自动生化分析仪测定AMI患者CK-MB阳性率比较无差别(P>0.05)。结论心肌三联检测卡对AMI早期诊断具有高灵敏度和高特异性,心肌三联检测卡操作方便,实用,实验结果快速准确,对诊断AMI具有较好的临床诊断价值。
Objective To investigate the diagnostic value of myocardial triple detection card in acute myocardial infarction. Methods The myocardial Mb, CTnI and CK-MB in 41 patients with AMI and 21 healthy controls were determined by myocardial triplex test and CK-MB (CK-MB≥25IU / ml is positive). Results The positive rates of Mb, CtnI and CK-MB in myocardial infarction patients with AMI were 87.80%, 51.00% and 21.95%, respectively. The positive rate of healthy subjects was 4.76% The positive rate of CK-MB was 26.83% and the positive rate of healthy subjects was 4.76%. Cardiac triple detection card and Hitachi 7020 automatic biochemical analyzer measured AMI CK-MB positive rate was no difference (P> 0.05). Conclusions Cardiac triple detection card has high sensitivity and specificity for early diagnosis of AMI. Cardiac triple detection card is easy to operate and practical, and the experimental results are fast and accurate, which has a good clinical diagnostic value in the diagnosis of AMI.
