目的探讨肌钙蛋白T(c Tn T)、肌钙蛋白I(c Tn I)与肌酸激酶同工酶(CK-MB)对急性心肌梗死(AMI)的诊断价值。方法选取2012年1月—2013年1月保定市易县医院收治的因急性胸闷、胸痛入院确诊的AMI患者112例作为观察组,另选取同期保定市易县医院患有其他疾病(排除心脏疾病)的患者112例作为对照组。检测两组患者入院时c Tn T、c Tn I、CK-MB水平及观察组患者发病后2h、12h、24h、72h、10d的c Tn T、c Tn I、CK-MB水平。结果观察组患者c Tn T、c Tn I、CK-MB的阳性率高于对照组,差异有统计学意义(P<0.05);观察组患者c Tn T、c Tn I水平升高时间早于CK-MB(P<0.05)。结论 c Tn T、c Tn I及CK-MB均可用于诊断AMI,且c Tn T、c Tn I好于CK-MB。
Objective To investigate the diagnostic value of cTnT, cTnI and CK-MB in patients with acute myocardial infarction (AMI). Methods From January 2012 to January 2013, 112 patients with acute chest tightness and chest pain diagnosed by AMI in Baoding Yixian Hospital were selected as the observation group. Another group of patients with other diseases (excluding heart disease ) Of 112 patients as a control group. The levels of cTnT, cTnI, CK-MB and the levels of cTnT, cTnI and CK-MB in the two groups at admission were detected at 2h, 12h, 24h, 72h, 10d after onset. Results The positive rates of c Tn T, c Tn I and CK-MB in the observation group were significantly higher than those in the control group (P 0.05). The levels of c Tn T and c Tn I in the observation group were earlier than those in the control group CK-MB (P <0.05). Conclusion c Tn T, c Tn I and CK-MB can be used to diagnose AMI, and c Tn T, c Tn I is better than CK-MB.
