Kounis syndrome is an acute coronary syndrome triggered by allergic mediators that induce coronary vasoconstriction and thrombosis, leading to further myocardial damage and anaphylactic shock. Kounis syndrome is also a rare but severe adverse reaction to the COVID-19 vaccine, a phenomenon that underscores the importance of collecting and analyzing similar cases to improve treatment and prognosis. Through comprehensive searches of the Web of Science, Embase, and PubMed databases, this study aimed to gather detailed patient data on patients who developed Kounis syndrome after receiving the COVID-19 vaccine and to further investigate the possible underlying mechanisms using currently available studies.

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.
