Kounis Syndrome from Multiple Bee Stings

Dimitrios Mytas and colleagues published a letter to the editor entitled "Acute anterior myocardial infarction after multiple bee stings. A case of Kounis syndrome" in the International Journal of Cardiology volume 134, pages e129 to e131, 2009. An "anterior myocardial infarction" is a heart attack that affects the anterior (front-oriented) portion of the heart muscle. In this publication, they described the case of a 58-year-old man with no prior history of heart disease or cardiovascular risk factors who was stung several times at the same time on the head and neck by honeybees while outdoors working. He became dizzy and suffered an unspecified type of breathing difficulty, but remained awake. He was taken to the hospital, where he was noted to have a red itchy rash on his face, neck, and chest. While in the emergency department, he began to feel unwell, began sweating, grew pale, and complained of chest pain that traveled into both arms. He grew nauseated and vomited. An electrocardiogram was obtained, which was diagnostic for an acute heart attack. He was ultimately taken to the cardiac catheterization suite, where he had a stent placed in one of his coronary arteries. On follow-up months later, he suffered from residual (congestive) heart failure.
This event was felt to represent Kounis syndrome, which is the concurrence of an acute coronary syndrome with an allergic or hypersensitivity reaction. It can occur with no pre-existing coronary artery disease (e.g., with normal coronary arteries) or with existing, perhaps unrecognized, coronary artery disease, as appears to have been the case with this unfortunate victim.
Anyone who suffers a bee sting or any other event that may precipitate an allergic reaction (such as ant, wasp, yellowjacket, or jellyfish sting; exposure to grasses, pollen, poison oak/ivy/sumac; eating shellfish, nuts; snake venom poisoning) and complains of chest pain that might be indicative of a heart attack should seek medical attention immediately.
