Late stent thrombosis after wasp sting.

Myocardial infarction (MI) following a bee sting is a highly unusual reaction. A 65-year-old man allergic to honeybee venom was admitted to the emergency department suffering from a wasp sting with urticaria. The patient had a history of bare metal stent (BMS) 9 months previously with regular drug use. He experienced chest pain after the sting and electrocardiography revealed ST-segment elevation in the chest leads. Subsequently, the patient developed ventricular tachycardia disrupting hemodynamics. Sinus rhythm was obtained by cardioversion. Coronary angiogram revealed total stent thrombosis (ST) in the midportion of the left anterior descending coronary artery. Primary coronary intervention was successfully performed. Presence of shared pathways in allergic reaction and MI pathogenesis may be responsible for de novo or ST. To our knowledge, this is the first case of total occlusive late ST in BMS following a wasp sting.
