Abstract
A 64-year-old man presented with acute left-sided limb weakness and no abnormalities on brain CT perfusion imaging. The patient soon experienced cardiac arrest, and coronary angiography after successful cardiopulmonary resuscitation demonstrated complete occlusion of the anterior descending branch and circumflex branch mid-sections, as well as diffuse lesions in the right coronary mid-section. Atypical AMI manifestations complicate emergency diagnosis, necessitating high clinical vigilance and broad differential assessment during initial evaluation.
