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).
