A young man suffered an acute inferior myocardial infarction following
clinical use of cocaine as topical anesthesia. Coronary angiography s
howed occlusion of both the posterior descending and posterolateral ar

cerin and verapamil, a finding consistent with thrombotic occlusion. A
subsequent angiogram 3 months later showed no residual lesions.
