An unusual case of two acute coronary syndrome episodes caused by allergic and non-allergic coronary artery dissection with potential coronary vasospasm association: a case report.

ABSTRACT:

Background

Type I variant Kounis syndrome is characterized by coronary spasm following an allergic or anaphylactic reaction. Coronary spasm is also recognized as a contributing factor in spontaneous coronary artery dissection (SCAD).

Case summary

A 46-year-old woman presented to the emergency room with a chief complaint of chest discomfort following the ingestion of a steamed bun. A marked decrease in systolic blood pressure and a prominent rash on her forearms and groin suggested anaphylactic shock. Upon stabilization of vital signs, acute coronary syndrome (ACS) was suspected based on electrocardiogram findings and symptoms, prompting an emergency coronary angiography (CAG). The CAG revealed severe stenosis with coronary artery dissection in the right coronary artery (RCA)
