Hyperacute synchronous cardiocerebral infarction in a patient with new-onset atrial fibrillation: a case of myocardial infarction with nonobstructive coronary arteries Supplementary data

Hyperacute synchronous cardiocerebral infarction (CCI) is an extremely rare condition with an incidence of
0.009%. In the acute stage of ischemic stroke, there is a high prevalence of ECG abnormalities. Prolonged
QTc, atrial fibrillation (AF) and ECG changes indicative of ischemic heart disease, such as Q waves, ST
depression, and T wave inversion, were the most prevalent changes. There are three types of simultaneous
CCI: cardiac conditions that cause cerebral infarction, cerebral infarction caused by cardiac conditions, and
(c) dysregulation of the brain–heart axis or cerebral infarction causing myocardial infarction. Herein, we
present a case of hyperacute synchronous CCI in an elderly patient with new-onset AF and myocardial
infarction with nonobstructive coronary arteries (MINOCA).

超急性同步性心脑梗死（Hyperacute synchronous cardiocerebral infarction, CCI）是一种极为罕见的病症，发病率仅为0.009%。在缺血性脑卒中急性期，心电图异常的患病率较高。其中校正QT间期（QTc）延长、心房颤动（AF）以及提示缺血性心脏病的心电图改变（如Q波、ST段压低与T波倒置）最为常见。同步性心脑梗死可分为三种类型：一是心脏疾病诱发脑梗死，二是脑梗死引发心脏疾病，三是脑-心轴调节异常或脑梗死导致心肌梗死。本文报告1例合并新发心房颤动（AF）及非阻塞性冠状动脉心肌梗死（myocardial infarction with nonobstructive coronary arteries, MINOCA）的老年患者的超急性同步性心脑梗死病例。
