摘　　要：在心肌梗死后的心室重构进程中,梗死心肌周围边缘带与恶性室性心律失常密切相关。心脏磁共振(CMR)可对边缘带进行量化评价,使其对恶性室性心律失常、心源性猝死的预测成为可能,本文对边缘带易于发生室性心律失常的病理生理机制、CMR量化的边缘带对室性心律失常、心源性猝死的预测价值及研究进展进行综述。In the progress of ventricular remodeling after myocardial infarction,the heterogeneity of peri-infarct border zone is related to fatal ventricular arrhythmia.Cardiac magnetic resonance(CMR)can be used to quantitatively evaluate the peri-infarct border zone,making it possible to predict the risk of ventricular arrhythmia and sudden cardiac death.In this paper,we review the pathophysiology and electrophysiological remodeling of border zone,as well as the progress of the predictive value of quantitative border zone assessed by CMR for ventricular arrhythmia and sudden cardiac death.
