摘要
目的研究心电图对应导联ST段压低在急性心肌梗死患者中的临床意义。方法将2011年8月至2012年9月湛江中心人民医院收治的103例急性心肌梗死患者根据导联ST段是否发生变化分为两组:ST段发生变化(A组,44例),ST段未发生变化或压低<0.1 mV(B组,59例),分析比较两组患者狭窄情况及血清标志物肌酸磷酸激酶(CPK)和肌酸磷酸激酶同工酶(CPK-MB)水平。结果 A组患者有冠状动脉狭窄29例(67.2%),发现多支冠状动脉病变12例(27.2%);B组有冠状动脉狭窄27例(45.1%),发现多支冠状动脉病变10例(16.9%),冠状动脉狭窄程度A组显著高于B组(χ2=6.35,4.43,P<0.05);A组患者血清CPK水平低于B组、CPK-MB水平高于B组,比较差异有统计学意义(t=7.4903,6.8401,P<0.05);A组患者出现严重心律失常、心力衰竭、心源性休克的发生率均显著高于B组(χ2=9.05,9.52,11.37,P<0.05)。结论急性心肌梗死时心电图对应导联ST段压低,冠状动脉狭窄程度更严重,且心律失常、心力衰竭等并发症发生率高,临床中应高度重视,采取积极的治疗措施。
Objective To study the clinical significance of ECG ST-segment depression for acute myo-cardial infarction. Methods One hundred and three patients with acute myocardial infarction in Zhanjiang Central People＇s Hospital from August 2011 to September 2012 were divided into two groups according to the ST segment change ,44 patients with ST-segment changes were divided as group A ,59 patients with no ST segment change or depression less than 0.1 mV patients were divided as group B. Stenosis,level of ser-um markers creatine phosphokinase（CPK） and creatine phosphokinase（CPK-MB） of the two groups were compared. Results There was 29 patients （67.2%） with coronary artery stenosis, 12 patients （27.2%） with muhivessel coronary artery stenosis in group A. There were 27 patients （ 45.1% ） with coronary artery stenosis, 10 patients（ 16.9% ）with multivessel coronary artery stenosis in group B; coronary artery stenosis in group A was significantly higher than that in group B（ x^2 = 6.35,4.43, P 〈 0.05 ）. The level of serum CPK in group A was lower than that in group B,and the level of CK-MB was higher than that in group B, with statistically significant difference （ t = 7. 4903,6. 8401, P 〈 0.05 ）. Incidence of serious arrhythmia, heart failure,cardiogenic shock were higher in Group A than those in group B with statistically significant difference （ x^2 = 9.05,9.52,11.37, P 〈 0.05 ）. Conclusion In the acute myocardial infarction, coronary stenosis is more serious with corresponding ST segment depression, and incidence of arrhythmias, heart fail-ure and other complications are higher. Much attention should be paid to it and active treatment measures should be adopted.
