急性心肌梗死并对应导联ST段改变的意义

Clinic significance accompanied ST change of correspondence lead in acute myocardial infarction

目的:探讨急性心肌梗死(AMI)伴有对应导联ST段改变的临床意义。方法:测定176例AMI患者梗死部位对应导联ST段下移的程度,根据ST段下移的程度患者被分为3组:无对应性ST段改变组(A组);伴对应导联ST段下移0.05～0.15mV组(B组);伴对应性ST段下移>0.15 mV组(C组),并记录4周内发生的严重并发症及死亡率。结果:(1)AMI患者有38.1％存在对应导联ST段改变;(2)A组与B组的并发症与死亡率无显著差异(P>0.05),C组的并发症及死亡率与A、B组相比有显著差异性(P<0.05)。结论:急性心肌梗死患者伴有对应导联ST段下移>0.15mV可作为判断病情严重程度与估计预后的指标之一。

Objective:To study the clinic significance accompanied ST change of correspondence lead in acute myocardial infarction (AMI). Methods: Electrocardiograph (ECG) was examined in 176 patients with AMI. The AMI patients were divided into 3 groups according accompanied ST change of correspondence lead. Group A includes AMI patientswithout accompanied ST change of correspondence lead. Group B include AMI patients accompanied ST segment depression of 0-05-0.15 mV on correspondence lead. Group C include AMI patients accompanied ST segment depression of >0. 15 mV on correspondence lead. Results: (1) There were 38. 1% patients accompanied ST change of correspondence lead in AMI patients; (2) Complication and death rate were no significantly difference between group A and B ( P >0. 05); (3) Complication and death rate of group C increased significantly ( P <0. 05) compared with group A and B. Conclusion: Accompanied ST depression of >0. 15 mV on correspondence lead in AMI patients can be regard as an index of judgment severity of an illness and evaluation prognoses.
