Different types of Kounis syndrome caused by different episodes of bee sting anaphylaxis: Misfortunes never come singly

We report our experience with a 69-year-old man who had different types of Kounis syndrome over a short time frame, caused by two episodes of bee sting anaphylaxis. After his first allergic reaction to a bee sting, he experienced a non–ST-segment elevation myocardial infarction; he was treated with percutaneous coronary intervention for near-occlusion of his right coronary artery. This episode was deemed type 2 Kounis syndrome. Four weeks later, we electively treated the nonculprit residual stenosis in his left anterior descending artery. Unfortunately, 2 weeks after this elective procedure, he experienced anaphylactic shock due to a second bee sting. Electrocardiography showed ST elevation in the anterior leads, and emergent coronary angiography showed thrombotic occlusion of the newly implanted stent in the left anterior descending artery. This second episode was deemed type 3 Kounis syndrome.
