Journal ArticleDOI
High plasma levels of factor viii and the risk of recurrent venous thromboembolism
Paul A. Kyrle,Erich Minar,Mirko Hirschl,Christine Bialonczyk,Milena Stain,Barbara Schneider,Ansgar Weltermann,Wolfgang Speiser,Klaus Lechner,Sabine Eichinger +9 more
TL;DR: Patients with a high plasma level of factor VIII have an increased risk of recurrent venous thromboembolism, and the likelihood of recurrence at two years was higher than among patients with lower levels.
Journal ArticleDOI
The risk of recurrent venous thromboembolism in men and women.
Paul A. Kyrle,Erich Minar,Christine Bialonczyk,Mirko Hirschl,Ansgar Weltermann,Sabine Eichinger +5 more
TL;DR: The risk of recurrent venous thromboembolism is higher among men than women and remains unchanged after adjustment for age, the duration of anticoagulation, and the presence or absence of a first symptomatic pulmonary embolism.
Journal ArticleDOI
D-dimer levels and risk of recurrent venous thromboembolism
S. Eichinger,Erich Minar,Christine Bialonczyk,Mirko Hirschl,Peter Quehenberger,Barbara Schneider,Ansgar Weltermann,Oswald Wagner,Paul A. Kyrle +8 more
TL;DR: Patients with a first spontaneous VTE and a D-dimer level of less than 250 ng/mL after withdrawal of oral anticoagulation have a low risk of VTE recurrence, and a laboratory method that measures multifactorial thrombophilia is required.
Journal ArticleDOI
Tissue factor-positive microparticles: cellular origin and association with coagulation activation in patients with colorectal cancer.
Gregor Hron,Marietta Kollars,Heinz Weber,Verena Sagaster,Peter Quehenberger,Sabine Eichinger,Paul A. Kyrle,Ansgar Weltermann +7 more
TL;DR: High levels of TF (+) MPs in cancer patients and their correlation with D-dimer suggest that TF (+), the circulating tissue factor-positive microparticles, might be involved in hemostasis activation incancer patients.
Journal ArticleDOI

TL;DR: In this paper, the authors performed a cohort study to determine the risk for recurrent venous thromboembolism (VTE) among patients with inflammatory bowel disease (IBD) compared with subjects without IBD.
