Factors affecting fibrinopeptide-A levels in patients with venous thromboembolism during anticoagulant therapy.
The prompt reduction of elevated fibrinopeptide A (FPA) levels (normal less than 1.3 pmole/ml) by heparin therapy in patients with thromboembolism suggests that measuring the FPA level may provide a good index of disease activity and be a useful method of monitoring therapy. Sepsis or malignancy may elevate FPA levels and coexist with thromboembolism. FPA levels were surveyed in 51 patients wit...
متن کاملPlasma levels of protein C and vitamin K-dependent coagulation factors in patients on long-term oral anticoagulant therapy.
Plasma levels of protein C (PC) and vitamin K-dependent coagulation factors (factors II, VII, IX and X) were measured in 100 specimens from patients on long-term warfarin therapy. Both activities and antigens of these coagulation factors were decreased, depending on the thrombotest values. Factor II activity/antigen ratio and factor X activity/antigen ratio were correlated well with thrombotest...
متن کاملAnticoagulant Therapy during Pregnancy
Fourteen patients were treated with anticoagulants during 15 pregnancies. Eleven had venous thrombosis, three with pulmonary embolism; three had prosthetic heart valves; and one had mitral stenosis with pulmonary hypertension. AU 15 were treated with heparin and 10 with warfarin. The mean duration of heparin therapy was 4-5 weeks and of warfarin 14 weeks. There were two minor episodes of recurr...
متن کاملInfluence of coagulation and anticoagulant factors on global coagulation assays in healthy adults.
It remains unclear how coagulation and anticoagulant factors influence global coagulation assays such as prothrombin time (PT), activated partial thromboplastin time (aPTT), and thrombin generation assay (TGA). We measured PT, aPTT, coagulation factor and protein levels, and TGA parameters (lag time, endogenous thrombin potential [ETP], and peak thrombin) in 252 apparently healthy adults. Vitam...
متن کاملLevels of coagulation factors and venous thromboembolism.
BACKGROUND AND OBJECTIVES Altered levels of coagulation factors have been included among the abnormalities that may increase the risk of venous thromboembolism (VTE) in otherwise healthy subjects. INFORMATION SOURCES According to the studies that have been carried to test this hypothesis only elevated levels of factor VIII and fibrinogen emerged as independent risk factors for VTE. STATE OF...
