title: Myocardial infarction, other arterial thrombosis and invasive coronary procedures, in hemaophilia B: a critical evaluation of reported cases.
abstract: Myocardial infarction and other arterial thrombosis are commonly maintained to be rare in hemophilia patients. This, in general, seems true but the occurrence of a thrombotic event in hemophilia B is not exceptional. A thorough search of the literature has yielded 13 patients with myocardial infarction and 1 patient with a cerebrovascular accident. There were three fatalities. In five cases MI occurred after infusion of Prothrombin Complex Concentrates. In three additional patients the event occurred after infusion of plasma, Feiba or cryoprecipitate supernatant. Four patients had an antero-lateral infarction. Two had a non-Q infarction and one each showed a multiple or a posterior-inferior form. Several therapeutic coronary procedures (GABG and PTCA) were carried out in hemophilia B patients without undue complication providing adequate level of FIX were maintained. Heparin prophilaxis was used in all patients but one. The analysis of the literature indicates that (1) MI may occur in hemophilia B patients and (2) that invasive coronary artery therapeutic procedures may be carried out without complications.
