Active clinical trials for "Thrombosis"

Nattokinase is a potent fibrinolytic enzyme extracted from Natto. The objective of this study was to compare the efficacy of the natto extract taken by healthy volunteers, dialysis patients, and patients with cardiovascularrisk factors on the fibrinolytic factors and blood lipids. The study has two primary objectives: to evaluate the effect of oral intake of nattokinase in normal subjects, patients under dialysis, and patients of cardiovascular high risk group, and to compare the effect of oral intake of nattokinase among three groups. Fifteen subjects, 20-70 years, for each group will be enrolled to take the capsules of natto extract orally for 2 months. Fibrinolytic factors, vital signs and blood lipids for efficacy, and body weight, renal function and self-administered questionnaire for safety will be assessed at screening, 3, 7, 28, and 56 days after the initiation of intake, and 2 weeks after the cease of intake.

The purpose of this study is to assess efficacy and safety of optional vena cava filter implanted 3 months in prevention of recurrent pulmonary embolism in patients presenting with acute pulmonary embolism associated with thrombotic risk factors

The purpose of this study is to learn more about why patients with diabetes have increased heart attacks, strokes and other illnesses due to blood clots causing blockage of a blood vessel. The proposed protocol will study the separate and combined effects of hyperglycemia and hyperinsulinemia on endothelial function and fibrinolytic balance in Type 2 DM. Our hypothesis is that hyperglycemia, rather than hyperinsulinemia, is responsible for the dysregulation of fibrinolytic balance in diabetics.

Brigham and Women's Hospital will coordinate a Quality Improvement Initiative at other hospitals that focuses on whether physician notification prior to discharge of high risk VTE patients will reduce the incidence of VTE after hospital discharge.

To study the safety and effectiveness of several doses of PD 0348292 compared to enoxaparin in preventing blood clots in the lungs or deep leg veins of patients after knee surgery

This study is requested by PMDA to confirm the optimal dose for THR (total hip replacement).

The purpose of this study is to evaluate the efficacy of 3 different dosing regimens of enoxaparin in achieving adequate antithrombotic aFXa levels in critically ill patients. The relationship between appearance of DVT and antithrombotic aFXa levels will also be assessed and risk factors associated with inadequate aFXa levels under standard enoxaparin dosages will be searched for.

The aim of this study was to compare the safety and efficacy of warfarin versus placebo, administered for 6 months, in the prevention of thromboembolic complications after transvenous cardiac devices implantation in high-risk patients.

The purpose of this study is to learn more about why patients with diabetes have increased heart attacks, strokes and other illnesses due to blood clots causing blockage of a blood vessel. The proposed protocol will study the separate and combined effects of high glucose and high fats on certain cardiovascular responses in Type 2 DM.

The purpose of this study is to evaluate the effect of Low Molecular Weight Heparin (LMWH) (Fragmin, dalteparin) versus Unfractionated Heparin (UFH) on the primary outcome of proximal leg Deep Vein Thrombosis (DVT) diagnosed by compression ultrasound, and the secondary outcomes of Pulmonary Embolism (PE), bleeding, Heparin-Induced Thrombocytopenia (HIT), and objectively confirmed venous thrombosis at any site.
