Endothelial haemostatic factors may be associated with mortality in patients on long-term anticoagulant treatment

Thrombosis and Haemostasis

Abstract

The aim of the present study was to test if long-term mortality could be predicted by endothelial derived haemostatic variables in a population with high morbidity due to thromboembolic disease. Plasma samples were drawn from 212 out-patients treated with oral anticoagulants, at the beginning of the study, and analyzed for mass concentration of tissue plasminogen activator (tPA) and its inhibitor (PAI-1), and von Willebrand factor. In the course of 3.8-year follow-up 45 patients died, including 38 vascular deaths. We found that all-cause mortality was significantly associated with increased levels of vWF and tPA. For vascular mortality there was a significant association with all three haemostatic variables (tPA, PAI-1, vWF). For vWF there was a 3-fold increase in total and vascular mortality in the highest quartile compared to the lowest quartile. There were 27 vascular deaths in the group of patients with a tPA-value above the median compared to 11 in those with a tPA below the median. In multivariate Cox regression analysis (including: age, sex, smoking habits, body mass index, diabetes mellitus, hypertension, tPA, PAI-1, and vWF), vWF and smoking were independently significantly associated with all-cause mortality, and tPA ...Continue Reading

Cardiovascular Disease Pathophysiology

Cardiovascular disease involves several different processes that contribute to the pathological mechanism, including hyperglycemia, inflammation, atherosclerosis, hypertension and more. Vasculature stability plays a critical role in the development of the disease. Discover the latest research on cardiovascular disease pathophysiology here.

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
