The Kounis-Zavras syndrome with the Samter-Beer triad.

We present a case of Kounis-Zavras syndrome in the setting of aspirin-induced asthma, or the Samter-Beer triad of asthma, nasal polyps, and aspirin allergy. The Kounis-Zavras syndrome, also known as Kounis syndrome, leads to angina pectoris or acute coronary syndrome secondary to coronary vasospasm in response to an allergic stimulus, leading to mast-cell degranulation of vasospastic mediators. The vasospasm can result in myocardial infarction, as it did in our patient.
