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

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).
