Kounis syndrome type I in a victim of cardiopulmonary arrest after hymenoptera sting.

Kounis syndrome is a relatively rare entity in which allergic or hypersensitivity reactions (including anaphylaxis) coexist with acute coronary syndromes. We report a case of Kounis syndrome type I variant in a 51-year-old male, victim of an out-of-hospital cardiac arrest a few minutes after a hymenoptera sting. Ιn-hospital cardiopulmonary resuscitation was provided and return of spontaneous circulation was achieved.
