Why the study?
Variant angina is difficult to recognize preoperatively, and unconscious patients cannot report symptoms during general anesthesia, complicating early detection of potentially lethal coronary spasm.
Highlights the risk of severe bradycardia, hypotension, and ventricular fibrillation due to coronary spasm in patients with undiagnosed variant angina undergoing general anesthesia.

Undiagnosed variant angina risks perioperative arrest; single case leaves open need for targeted preoperative screening.
Variant angina, which is associated with coronary artery spam, is difficult to recognize on routine preoperative evaluation. Coronary spasm results in myocardial ischemia and even lethal arrhythmia in severe cases. Since patients are unconscious and cannot complain of symptoms during general anesthesia, early detection of such an event is difficult, and it could lead to severe bradycardia or cardiac arrest. We report a case of a patient with previously undiagnosed variant angina who experienced severe hypotension and ventricular fibrillation during general anesthesia.
