ABSTRACT
Kounis syndrome, while an acute coronary syndrome, occurs in the context of a hypersensitivity reaction, allergies, or anaphylaxis and is subdivided into three types: coronary spasm in normal arteries, instability of plaques in atherosclerotic coronary arteries, and thrombosis of coronary stents. Herein, the case of a 73-year-old patient who, after administration of amoxicillin/clavulanic acid, went into cardiorespiratory arrest with evidence of ST-T segment elevation on electrocardiogram is reported. Coronarography revealed no obstructive lesions, and spontaneous resolution of electrocardiographic abnormalities was observed. A review of anamnesis with the family revealed a previous allergy to penicillin. The tryptase dosage was strongly positive. Kounis syndrome type 2 was diagnosed, and the clinical outcome was good.
