【摘要】 目的 :探讨心肌肌钙蛋白T(cTnT)与急性心肌梗塞范围的关系。方法 :研究了 33例老年急性心肌梗塞 (AMI)患者的cTnT与心电图QRS记分测定心肌梗塞范围的相关性。结果 :2 4小时内的cTnT峰值与心肌梗塞范围无相关性 (r=0 .33,P >0 .0 5 ) ;2 4小时后cTnT峰值与心肌梗塞范围呈正相关性 (r =0 .87,P <0 .0 1)。结论 :老年AMI后cTnT的后期释放峰值是判断心肌梗塞范围的良好参数。更多还原

【Abstract】 Objective:To study the correlation between cardial troponin T(cTnT)levels and myocardial infarct size.Methods:The serum levels of cTnT was tested,myocardial infarct size was assessed by QRS scoring of electrocardiography in 33 patients with acute myocardial infarction(MAI).Results:The peak cTnT value within 24 hours of AMI not correlated with the myocardial infarct size,but a good correlation was found between the peak cTnT value 24 hours after AMI and myocardial infarct size(r=0.87, P <0.01),Conclusion:The study indicated the peak cTnT value 24 hours after AMI is a useful marker to assess myocardial infarct size.更多还原
