Histamine--can it cause an acute coronary event?
Myocardial infarction (MI) occurring during the course of an allergic urticarial reaction in the absence of systemic hypotension has been rarely reported. This paper reports the case of a 28-year-old woman with no significant risk factors for coronary artery disease who presented with generalized urticaria associated with chest pain and had electrocardiographic and enzymatic evidence of an acute MI. Review of the literature suggests that local histamine release may induce spasm of the coronary vasculature, thus leading to myocardial ischemia and infarction.
