Kounis Syndrome, a Case of Vancomycin Associated Coronary Artery Vasospasm Resulting in Myocardial Infarction

The curious case of Kounis syndrome: exploring clinical manifestations and management in the presence of nonobstructive coronary arteries

Kounis syndrome, an allergic hypersensitivity coronary disorder, is a rare but potentially life-threatening condition triggered by various allergens, including medications. We present the case of a 41-year-old male with no prior cardiac history, who developed Kounis syndrome following vancomycin administration for suspected cellulitis. The patient initially presented with rash, fever, and malaise, which progressed to chest discomfort associated with diaphoresis and elevated troponin levels. Diagnostic evaluations, including electrocardiographic changes and coronary angiography, confirmed a diagnosis of type I Kounis syndrome. This case adds to the limited literature on vancomycin-induced Kounis syndrome, and underscores the importance of considering this diagnosis in patients with myocardial damage following exposure to potential allergens.

Ceftriaxone-induced Kounis syndrome: A case report and review of the literature

Kounis syndrome is defined as cardiovascular symptoms that occur secondary to allergic or hypersensitivity insults, and is also called allergic angina and allergic myocardial infarction. We report a case of pre-operative ceftriaxone-induced Kounis syndrome with no evident dermatological manifestation, and describe our diagnostic dilemma. The patient was symptomatically managed and discharged in stable condition with a warning against future use of ceftriaxone.
