This is the report on a 77-year-old female patient on antihistami-nic associated to pseudoephedrin to treat an allergy condition in upper airways. The patient was admitted to the Emergen-cy Unit with acute myocardial infarction and ST segment elevation in the antero-lateral wall. Cardiac catheterism showed tortuous coronaries, no obstructive lesions, and baseline hypercontractility associated to antero-apical akinesia on left ventriculography. As a result of repeated pericardial strokes, the patient was submitted to pleuro-pericardial draina-ge. Rheumatological causes were ruled out. The patient was discharged after 30 days in good clinical conditions. DESCRIPTORS: Myocardial infarction. Histamine H1 antago-nists. Cardiomyopathies, physiopathology. Cardiomyopathies, etiology.
