It is a rare, and frequently undiagnosed syndrome that is characterized by an anaphylactic reaction. Allergens cause massive degranulation of mast cells leading to coronary spasm, microvascular angina, and/or endothelial dysfunction with myocardial infarction. The annual incidence of severe, life-threatening anaphylaxis with circulatory symptoms is about 7.9-9.6 cases per 100,000 people. More than 300 cases of KS have been described after exposure to various agents such as drugs, insect venoms, food, or medicated stents. Although the incidence of KS is very low, the incidence of myocardial infarction due to anaphylaxis secondary to gadolinium is even lower, reported in a range of 0.002-0.01%.
