Abstract
IntroductionHymenoptera venoms contain thrombogenic substances that might be responsible for cardiovascular events independent of anaphylactic reactions.Case presentationWe report a 55-year-old man who experienced an acute ST-elevation myocardial infarction after wasp sting. The patient presented without signs of anaphylaxis or shock. The coronary angiography showed an acute stent thrombosis of the right coronary artery. Percutanous coronary intervention was performed immediately and this is an example for a cardiovascular complication associated with a hymenoptera sting, since the vasoactive, inflammatory, and thrombogenic substances of hymenoptera venoms potentially cause stent thrombosis and myocardial ischemia. To the best of our knowledge this is the first report of acute stent thrombosis in a sirolimus-eluting stent following hymenoptera sting.ConclusionStent thrombosis is a possible complication after wasp sting induced by thrombogenic substances of the hymenoptera venom.

Summary
Hymenoptera venoms contain thrombogenic substances that might be responsible for cardiovascular events, especially in patients with coronary artery disease. Case presentation A 55-year-old Caucasian German man with known ischemic heart disease presented in our emergency room, with an acute inferior myocardial ST-elevation infarction. Three years before stenoses of the proximal left anterior descending and the proximal right coronary artery were treated by PCI and implantation of two bare metal stents,. Cases Journal 2009, 2:7800 http://casesjournal.com/casesjournal/article/view/7800 followed by PCI and implantation of a sirolimus-eluting stent (Cypher®) of an In-stent restenosis in the right coronary artery one year later. After admission to the emergency room, coronary angiogram was performed showing a thrombosis in the two year old sirolimus-eluting stent of the right coronary artery occluding the vessel sub-totally. The patient was discharged 6 days after myocardial infarction on a regime of aspirin, clopidogrel, bisoprolol, ramipril and simvastatin
