Resumo
A case of a 57-year-old man with hypertension and stable angina, on aspirin therapy, who was treated for epistaxis with intranasal cocaine, and who subsequently suffered a non-Q wave myocardial infarction is reported. Of note, the cocaine was administered in a manner which differs from that advocated in standard references. Specifically, intranasal packing soaked with 4% cocaine was left in place with continuous nasal mucous membrane contact over 5 to 6 hours. The authors speculate that myocardial infarction occurred on the basis of coronary artery spasm. This case should alert practitioners to myocardial ischemia occurring as a complication of the therapeutic use of intranasal cocaine for the treatment of epistaxis.
