title: Clopidogrel-associated autoimmune thrombocytopenic purpura.
abstract: We report the case of a 51-year-old male who underwent coronary stent placement for the treatment of an acute myocardial infarction. One week later, he developed symptomatic autoimmune thrombocytopenia likely related to clopidogrel use. This was successfully treated with intravenous methylprednisilone and platelet transfusions.
