Abstract

Acute coronary syndromes can develop with an unusual and challenging presentation. Kounis syndrome is a mostly overlooked Acute Coronary Syndrome (ACS) in the setting of anaphylactic or anaphylactoid reactions in response to an allergic insult that can lead to severe complications including cardiac arrest. A 52-yearold- man presented to the emergency department of our hospital because of acute transient loss of consciousness that developed some minutes after almonds ingestion. The complex diagnostic workup led to the diagnosis of vasospastic Kounis syndrome, an infrequent type of acute coronary syndrome, mostly overlooked, with challenging diagnostic and therapeutic features. Peculiarities on clinical presentation, the approach adopted by the emergency physician and the consultant cardiologist to achieve the correct diagnosis and our proposed management with a brief revision of the literature will be reported. Unusual clinical presentations of acute coronary syndromes represent part of the pitfalls that an emergency physician can face during the everyday practice. Prompt identification of these conditions is always struggling but of crucial importance to improve patient prognosis with a correct diagnostic work-up and therapeutic management.
