title: Thrombosis or myocardial infarction in congenital clotting factor abnormalities and chronic thrombocytopenias: a report of 21 patients and a review of 50 previously reported cases.
abstract: Nine patients are described with hereditary clotting factor abnormalities and thrombosis and 35 others previously reported in the literature. An additional 11 patients with myocardial infarction observed by the authors and 12 more reported by others are also included. A patient with non-immune thrombocytopenia and myocardial infarction is presented, as well as three additional patients recorded in the literature. This study underscores the little-recognized phenomenon of uncontrolled thrombosis in these patients with "experiments of nature," in whom clotting studies reflect an impairment of coagulation comparable in degree to that achieved by oral anticoagulant therapy.
