心电图对ST段抬高型心肌梗死患者梗死面积的预测价值

Predictive value of electrocardiography for infarct size in patients with ST-segment elevation myocardial infarction

梗死面积是ST段抬高型心肌梗死主要不良心血管事件的独立预测指标。心脏磁共振(CMR)可全面展现梗死后心肌组织学变化特征,其晚期钆增强图像是活体检测和量化梗死面积及微血管阻塞的金标准。然而CMR获取成本较高,且存在禁忌证,而心电图评估梗死面积简便易行。本研究总结了目前心电图评估梗死面积的研究,为临床决策提供依据。

Infarct size is an independent predictor of major adverse cardiovascular events in ST-segment elevation myocardial infarction.Cardiac magnetic resonance(CMR)can fully demonstrate the histological characteristics of myocardial infarction,and late gadolinium enhanced images are the gold standard for in vivo detection and quantification of infarct size as well as microvascular obstruction.However,the acquisition cost of CMR is high and there are contraindications.ECG is simple and easy to evaluate the infarct size.This study summarizes the current studies on ECG assessment of infarct size and provides evidence for clinical decision-making.
