心电图aVR导联ST段改变对急性心肌梗死患者近期预后价值

目的探讨心电图a VR导联ST段改变对急性心肌梗死(AMI)患者近期预后价值的研究。方法收集我院2012年12月~2015年12月收治的90例首次发生AMI的患者的完整临床资料进行回顾性分析,按照心电图a VR导联ST段是否改变将其分为ST段抬高组和非ST段抬高组,比较2组性别构成比、GRACE危险评分、SYNTAX评分以及预后相关危险因素构成比。结果 90例AMI患者中,ST段抬高组51例,非ST段抬高组39例,2组男女构成比分别为70.6%、29.4%和74.4%、25.6%,差异无统计学意义(P0.05)。而ST段抬高组的GRACE危险评分及SYNTAX评分明显高于非ST段抬高组,差异均有统计学意义(P0.05)。2组预后相关危险因素中,ST段抬高组的AMI病史、吸烟史、糖尿病史、心功能≥3级、高血肌酐构成比均明显高于非ST段抬高组,差异均有统计学意义(P0.05)。结论心电图a VR导联ST段抬高在AMI患者近期预后评估中具有较高价值,并可作为AMI严重病变的重要依据。

Research on Recent Prognosis Value of Change in Electrocardiogram aVR-led ST Segment on Patients with Acute Myocardial Infarction

Objective To explore the research on recent prognosis value of the change in the electrocardiogram aVR-led ST segment on patients with acute myocardial infarction (AMI).Methods Fully clinical data of 90 patients suffering from AMI for the first time admitted by the Hospital from December,2012 to December,2015 admitted were retrospectively analyzed,the patients were divided into St segment elevation group and non-ST segment elevation group according to the availability of the change in the electrocardiogram aVR-led ST segment,and the gender composition ratio,GRACE risk scores,SYNTAX scores and prognosisrelated risk factors of two groups of patients were compared.Results Among 90 patients with AMI,51 patients were listed into ST segment elevation group,and 39 patients were listed into non ST segment elevation group,the composition ratios of men and women of two groups hit 70.6％,29.4％,74.4％ and 25.6％ respectively,the differences were no statistically significant(P ＞ 0.05).The GRACE risk scores and SYNTAX scores of patients in ST segment elevation group were significantly higher than such indexes of patients in non ST segment elevation group,and the differences were statistically significant (P ＜ 0.05).Among prognosisrelated risk factors of patients in two groups,the AMI history,smoking history,history of diabetes,heart function ≥3 and composition ratio of high serum creatinine in the ST-elevation group were significantly higher than such indexes of patients in non ST segment elevation group,and the differences were statistically significant(P ＜ 0.05).Conclusion The electrocardiogram aVR led-ST segment elevation delivers high value on recent prognosis assessment of patients with aAMI and it may be used as the important basis of AMI severe lesions.
