急性心肌梗死并对应导联ST段改变的意义

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患梗死部位对应导联ST段下移的程序，根据ST段下移的程度患被分为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＞0.15mV组（C组），并记录4周时发生的严重并发症及死亡率。结果：（1）AMI患有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差异（P＞0．05），C组的并发症及死亡率A，B组相比有显差异性（P＜0．05）。结论：急性心肌梗死患伴有对应导联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。

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

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.
