10.After logistic regression analyzing, only aVL lead ST segment elevation had correlation with the occlusion site in the left anterior descending coronary artery, the odd ratio is 5.778. Conclusion:Ⅰ ,aVl,aVR lead ST segment elevation and Ⅲ lead ST segment elevation all have value in predicting the occlusion site of the left anterior descending coronary artery, but the aVL lead ST segment elevation is best of all.
进行Logistic回归分析后,只有aVL导联ST抬高与左前降支近端病变有相关性,其优势比(OR值)为5.778。 结论:I、aVL、aVR导联ST抬高及Ⅲ导联ST抬高是预测AMI中左前降支病变部位的较好指标,但以aVL导联ST抬高最好。
