缺血性卒中患者心脏磁共振检查专家共识

Consensus of Experts on the Application of Cardiac Magnetic Resonance in Patients with Ischemic Stroke

卒中是我国居民致死、致残的首要原因,缺血性卒中(ischemic stroke,IS)约占卒中患者的70%。在IS中,心源性栓塞性卒中和来源不明的栓塞性卒中分别占20%~30%和30%~40%。心脏磁共振(cardiac magnetic resonance,CMR)检查作为一种重要的补充检查手段,不仅有助于IS病因的确认,还可以揭示IS新的发病机制。本文阐述了IS患者CMR检查的必要性、CMR检查技术的价值及在IS患者中的应用适应证,并推荐了IS患者的CMR检查流程,以便更好地为IS的病因诊断、治疗及二级预防提供帮助。

Stroke is the leading cause of death and disability in Chinese residents,with ischemic stroke(IS)accounting for approximately 70%of stroke patients.In IS,cardioembolic stroke and embolic stroke of undetermined source account for 20%-30%and 30%-40%,respectively.Cardiac magnetic resonance(CMR)examination is an important adjunctive diagnostic tool,facilitating the identification of IS etiology while also revealing the novel pathogenesis.This article discussed the necessity of CMR examination in IS patients,the value of CMR examination techniques,and the indications for its application in IS patients.It also recommended the procedure of CMR examination for IS patients to provide better help for the diagnosis,treatment,and secondary prevention of IS.
