Kounis syndrome type I

Kounis syndrome (KS) is a clinical entity characterized by the simultaneous appearance of allergic symptoms and acute coronary syndrome. Since its initial description in 1991, reviews and case descriptions have been added that are allowing a better understanding of its pathogenesis, for better management. Since 2010, three variants of this syndrome have been defined: vasospastic allergic angina (type I), allergic myocardial infarction (type II) and in-stent thrombosis with occlusive thrombus infiltrated by eosinophils and mast cells (type III). A patient discharged from our service with this diagnosis is presented and the electrocardiographic and angiographic images are shown.
