目的观察急性冠脉综合征(ACS)患者肌酸肌酶同工酶(CK-MB),肌钙蛋白(cTnI)以及心电图之间的关系。方法 2006年6月~2008年8月在我院急诊抢救并收入心内科住院且资料完整的ACS病例146例,患者就诊后立即行12导心电图检查,入院后2h内取静脉血测肌钙蛋白,肌酸肌酶同工酶。结果 ACS患者ST段抬高组中CK-MB和cTnI的检测阳性率明显高于非ST段抬高组,差异有非常显著性(P<0.01)。结论 ACS患者中ST段抬高者心肌损伤的发生率明显大于非ST段抬高者。
Objective To observe the relationship between CK-MB, cTnI and ECG in patients with acute coronary syndrome (ACS). Methods From June 2006 to August 2008, 146 cases of ACS patients who were hospitalized in our department and were admitted to Department of Cardiology with complete data were enrolled in the emergency department of our hospital. The patients received 12-lead electrocardiogram immediately after their diagnosis. Venous blood was taken for measurement of cardiac troponin , Creatine kinase isoenzyme. Results The positive rates of CK-MB and cTnI in ST-segment elevation group were significantly higher than those in non-ST-segment elevation group (P <0.01). Conclusion The incidence of myocardial injury in patients with ST segment elevation in ACS patients is significantly higher than that in non-ST segment elevation patients.
