摘要
目的:探讨二维超声心动图与心电图在急性心肌梗死患者左前降支病变部位判定方面的临床价值。方法:回顾性分析45例左前降支病变的急性心肌梗死患者的二维超声心动图和心电图资料,测量前间隔基底部残存运动正常心肌长度,以前间隔基底部残存运动正常心肌长度≤1.5 cm及心电图aVL导联ST↑为判定左前降支近段病变标准,分别统计两者诊断的敏感性、特异性、准确性、阳性预测值和阴性预测值,并对准确性做统计学分析。结果:前间隔基底部残存运动正常心肌≤1.50 cm的敏感性、特异性、准确性、阳性预测值及阴性预测值分别为78.26%、91.89%、86.67%、85.71%及87.18%。而心电图标准aVL导联ST↑分别为72.00%、75.00%、73.85%、64.29%及81.08%。两者的准确性具有统计学差异(P值为0.02)。结论:以前间隔基底部残存运动正常心肌≤1.5 cm对判断左前降支近段病变较心电图标准aVL导联ST↑具有更好的价值。
Objective：To evaluate the clinic value of two-dimension echocardiography （2-DE）and electrocardiogram （ECG） in occlusion site prediction of left anterior descending artery （LAD）. Methods：The data of 2-DE and ECG of 60 patients with acute myocardial infarction （AMI）in LAD occlusion were retrospectively analyze. The data included length of residual normal myocardium in antero-septal basal;respectively statistic the sensitivity,specificity,accuracy,positive predictive value and negative predictive value of the length of residual normal myocardium in anteroseptal basal （1.5 cm and the aVL lead ST segment elevation in predict proximal occlusion of LAD and a statistic analyse in accuracy. Results：The sensitivity, specificity, accuracy, positive predictive value and negative predictive value of the length of residual normal myocardium in antero-septal basal 〈1.5 cm were 78.26%,91.89%,86.67%,85.71% and 87.18%;the ST segment elevation in aVL lead were 72.00%,75.00%,73.85%,64.29% and 81.08%. The variance was significant in accuracy（P value： 0.02）. Conclusion： The value of the length of normal myocardium in antero-septal basal in predict proximal occlusion of LAD is better than the aVL lead ST segment elevation.
