Allergic acute coronary syndrome: Amoxicillin/clavulanic acid intake

Anaphylaxis rarely manifests as a vasospastic acute coronary syndrome (ACS). Kounis Syndrome (KS) is described as the coincidental occurrence of chest pain and clinical and laboratory findings of ACS. The prognosis depends on the magnitude of the initial allergic response, the patient’s sensitivity, comorbidities, the site of antibody antigen reaction, the allergen concentration, and the route of allergen entrance. We report a rare case of KS secondary to antibiotic allergy. This case may suggest that Kounis syndrome should be taught in the differential diagnosis of acute coronary syndromes. Clinicians should be aware of this adverse effect and consider it during diagnostic workup of myocardial injury
