Tissue factor pathway inhibitor (TFPI) is a multivalent Kurhage. The extent of structural abnormalities within the yolk sac vascular system appears to mirror the condition of the nitz-type proteinase inhibitor that directly inhibits factor Xa and, in a factor Xa–dependent fashion, produces feedback embryo, suggesting that the embryonic and extra-embryonic tissues are both responding to same ins...

BACKGROUND In view of the central role of the tissue factor-factor VIIa pathway in the initiation of blood coagulation, novel therapeutic strategies aimed at inhibiting this catalytic complex are currently being evaluated. A limitation of this new class of anticoagulants may be the lack of an appropriate strategy to reverse the effect if a bleeding event occurs. The aim of this study was to inv...

Tissue factor pathway inhibitor (TFPI) is a multivalent Kunitz-type proteinase inhibitor that directly inhibits factor Xa and, in a factor Xa-dependent fashion, produces feedback inhibition of the factor VIIa/TF catalytic complex responsible for the initiation of coagulation. To further define the physiologic role of TFPI, gene-targeting techniques were used to disrupt exon 4 of the TFPI gene i...

BACKGROUND This study sought to assess whether novel markers of hemostatic activity are predictive of coronary heart disease (CHD) and improve risk assessment. METHODS AND RESULTS Conventional CHD risk factors, the activation peptides of factor IX and factor X, factor VII activity and antigen, activated factor XII, prothrombin fragment 1+2, fibrinopeptide A, and fibrinogen were measured in 11...

Hemophilia A and B are caused by deficiencies in coagulation factor VIII (FVIII) and factor IX, respectively, resulting in deficient blood coagulation via the intrinsic pathway. The extrinsic coagulation pathway, mediated by factor VIIa and tissue factor (TF), remains intact but is negatively regulated by tissue factor pathway inhibitor (TFPI), which inhibits both factor VIIa and its product, f...

Symptomatic intracerebral hemorrhage (sICH) occurs in up to 7% of stroke patients treated with thrombolytic therapy. There are limited data on the effectiveness of the reversal agents used for intravenous tissue plasminogen activator related intracranial bleeds. We report a patient with sICH following intravenous thrombolysis whose intracerebral hemorrhage continued to expand despite treatment ...
