Abstract

Kounis syndrome (KS), also known as allergic angina, is a type-1 hypersensitivity reaction affecting the coronary vessels, leading to vasospasm. It manifests like an acute coronary syndrome on the electrocardiogram and is often underdiagnosed. Foods (such as peanuts and fish) and medications (mostly antibiotics and analgesics) are the common triggers. We report a 30-year-old patient who developed KS following a multivitamin injection.
