Detection of Myocardial Infarction by Cardiac Magnetic Resonance in Embolic Stroke Related to First Diagnosed Atrial Fibrillation

Elevated troponin levels are found in a significant number of patients who are diagnosed with acute embolic stroke (AES) after first diagnosed atrial fibrillation (AF). These myocardial injuries, which are known as cardiocerebral infarction (CCI), are potentially caused by coronary embolism and correspond to simultaneous cardiac and cerebral embolisms. However, this severe condition remains poorly understood. In this prospective study, we aimed to investigate the prevalence and the cardiac magnetic resonance (CMR) characteristics of CCI.Consecutive patients with first diagnosed AF hospitalized for AES in a neurovascular intensive care unit from 2019 to 2020 were included. Troponin Ic kineti…
