Increased fibrinopeptide A formation and thromboxane A2 production in patients with ischemic heart disease: relationships to coronary pathoanatomy, risk factors, and clinical manifestations.

In 98 patients with ischemic heart disease (IHD), independent of their clinical status (previous myocardial infarction, spontaneous angina or effort angina), a hypercoagulable state (indicated by significant elevation of fibrinopeptide A plasma level) and an increased platelet biologic activity were observed. Moreover, plasma fibrinopeptide A concentration and platelet aggregation were remarkably higher in patients with frequently occurring spontaneous clinical manifestations (active disease) than in IHD patients with relatively quiescent symptoms. Abnormalities of blood clotting and platelet changes were not significantly altered by the presence of severity of coronary angiographic fixed obstruction in IHD. Multiple regression analysis indicated that hypercoagulability and increased platelet biologic activity were not a consequence of differences in risk factor patterns in IHD patients compared to control subjects.
