Ischemic stroke （IS） complicated with cardiac injury is common and can lead to poor prognosis for patients. Currently， the diagnosis and treatment of IS is gradually shifting towards a multidisciplinary collaboration model of simultaneous treatment of brain and heart. Recently， cardiac magnetic resonance （CMR） imaging has become the gold standard for non-invasive evaluation of cardiac structure and function， and its role in IS is increasingly valued. This paper reviews the manifestations，features， injury mechanisms and clinical managementof IS complicated with cardiac injury， and the application of CMR imaging in IS， so as to provide theoretical basis for early identification and clinical management of IS patients with cardiac injury， along with the utilization of CMR in IS cases.
