Kounis Syndrome: A Comprehensive Review of Pathophysiology, Clinical Manifestations, Diagnostic Challenges, and Therapeutic Strategies
Main Article Content
Abstract
Kounis syndrome, also known as allergic angina or allergic myocardial infarction, is a rare but potentially life-threatening condition characterized by the acute onset of chest pain, myocardial infarction, or sudden cardiac death in the setting of allergic or hypersensitivity reactions. The syndrome encompasses a spectrum of acute coronary syndromes triggered by various allergic insults, including medications, insect stings, food allergens, and environmental exposures. The pathophysiology involves the activation of mast cells and platelets, leading to coronary artery spasm, atheromatous plaque erosion or rupture, and subsequent myocardial ischemia or infarction. Diagnosis can be challenging due to the diverse clinical presentations and the need for a high index of suspicion. Management includes the identification and avoidance of triggers, along with the use of standard therapies for acute coronary syndromes. This review aims to provide a comprehensive overview of Kounis syndrome, focusing on its pathophysiology, clinical manifestations, diagnostic considerations, and therapeutic strategies.
