Asthma induced myocardial infarction in a patient with normal coronary arteries: a case report and a pathogenetic hypothesis.
A 57 year old white woman is reported who developed a myocardial infarction during an attack of allergic asthma and was subsequently found to have a normal coronary arteriogram. The literature on myocardial ischemia and infarction associated with structurally normal coronary arteries is reviewed with particular reference to prostaglandin production, histamine release, platelet activation and the induction of coronary vasospasm. A hypothesis is constructed to explain asthma induced myocardial infarction in terms of interrelated pathogenetic mechanisms.
