title: Midventricular hypokinesis as a cardiac manifestation of anaphylaxis: a case report.
abstract: We report a case of anaphylaxis in which left midventricular hypokinesis was found by echocardiogram performed while the patient was hypotensive shortly after the onset of acute chest pain with S-T segment elevations. Cardiac injury was confirmed by elevation of cardiac enzymes. Repeated echocardiogram 2 days later demonstrated normal ventricular wall function and coronary angiogram demonstrated no angiographically apparent disease. We discuss possible mechanisms for cardiac injury and suggest mast cell-mediated coronary spasm as the most likely.
