Myocardial infarction in a patient with thrombotic thrombocytopenic purpura

摘要: Abstract A 63-year-old male with a prior history of thrombotic thrombocytopenic purpura was admitted sudden onset syncope. He denied chest pain. His initial blood chemistries were consistent acute relapse as indicated by microangiopathic hemolytic anemia and thrombocytopenia. The patient had evidence myocardial injury elevation cardiac enzymes. 12-lead electrocardiogram demonstrated ST (up to 5 mm) in leads V 2 6 . treated plasma exchange fresh frozen addition nitroglycerin, metoprolol prednisone tapering dose. After reviewing the literature, we believe that etiology damage remains elusive, but may be secondary an autoimmune phenomenon resulting microthrombosis myocarditis. We unable find any documentation about specific treatment such patients. Further studies are awaited regarding appropriate patients electrocardiographic changes.
