Active clinical trials for "Thrombosis"

More than 5 years ago the DVT FREE Registry was conceived. Its database consists of 5,451 ultrasound-confirmed DVT patients from 183 institutions. This database is rich in information of critical importance to health care providers. The information contained within the database will be revisited to provide more detailed analyses which will be used for risk factor assessment and for decision-making regarding the implementation of VTE Prophylaxis.

To examine the relationships among psychosocial factors and carotid atherosclerosis, myocardial ischemia, arrhythmias, and thrombosis.

To investigate hemostatic variables in relation to cardiovascular risk in the Framingham Offspring Study cohort.

In case of acute portal vein thrombosis (PVT) prothrombotic factors are identified in about 60% of cases, while a local condition is present in 30% of cases. Prothrombotic factors may indicate a long term anticoagulant therapy whereas the risk of recurrence seems low when a local condition is isolated (cholecystitis, angiocholitis, liver abces, diverticulitis, appendicitis, acute/chronic pancreatitis, chronic bowel inflammatory disease, acute hepatitis due to cytomegalovirus, bacteroïdes pylephlebitis, abdominal neoplasia such as adenocarcinoma of the colon, abdominal traumatism or surgery such as cholecystectomy, bariatric surgery or splenectomy). To date the impact of prothrombotic factors associated with local conditions responsible for acute PVT has not been well studied except for acute or chronic pancreatitis. No significant association has been pointed out in this pathology. The aim is to determine what are the risk factors of thrombotic recurrence or extension associated with local conditions responsible for acute non cirrhotic PVT, and to evaluate the rate of secondary long term anticoagulant therapy.

The study is designed to evaluate the role of platelets and immature platelets in the ethiopathology of deep venous thrombosis and pulmonary embolism.

National, multicenter, prospective, observational, non-interventional study. The objective is to determine if the switch from Vitamin K antagonists (VKA) to Xarelto in subjects treated with VKA with issues in deep venous thrombosis (DVT), and prevention of recurrent DVT and pulmonary embolism (PE) is associated with an improvement of the treatment satisfaction after 3 months. The treatment satisfaction will be measured by the Anti Clot Treatment Scale (ACTS) score.

Background: -How people respond to drugs depends in part on their genes. For some drugs, doctors can use an individuals genetic background to help in dosing the drug. Researchers want to know how doctors incorporate personalized or genomic medicine into clinical practice. Objective: -To study how physicians make personalized treatment decisions Eligibility: -Healthy adult primary care physicians who are internal (or family) medicine residents. Design: Participants will complete a screening form. Participants will put on a headset, called a head-mounted display, showing a virtual reality environment. The environment will contain an exam room and the virtual patient. After interacting with the virtual patient, participants will complete a series of survey measures. Participation will last for about 60 minutes. The virtual patient interaction and follow-up questions will be audio taped.

Several studies have confirmed that patients with cirrhosis possess an imbalance in procoagulant versus anticoagulant activity due to increased factor VIII and decreased protein C. Moreover, in the last two decades there has been an increased recognition that not only bleeding but also thrombosis complicates the clinical course of cirrhosis. The prevalence and pathogenesis of portal vein thrombosis (PVT) in patients with cirrhosis without hepatocellular carcinoma are not clearly defined. The Aim of this study is to assess the prevalence of portal vein thrombosis in patients with cirrhosis without hepatocellular carcinoma, and to prospectively assess the risk factors, outcome, and prognosis in these patients. The investigators plan to enroll two hundred patients with liver cirrhosis. The patients are going to follow up for one year and evaluate at baseline and every 6 months by liver function tests, coagulation test, upper abdomen ultrasound. All relevant clinical events will be evaluated at every follow up.

The WATCHMAN LAA Closure Technology is designed to prevent embolization of thrombi that may form in the LAA, thereby preventing the occurrence of ischemic stroke and systemic thromboembolism. The objectives of this observational, prospective, non-randomized multicenter study are (1) to compile real-world clinical outcomes data for WATCHMAN LAA (left atrial appendage) Close Technology in patients who are implanted with the WATCHMAN device in a commercial clinical setting and (2) to collect real-world usage data that may be needed for reimbursement of WATCHMAN technology in certain countries.

Fondaparinux is an anticoagulant used in the prevention and treatment of thromboembolic disease. It has recently been approved in the European Union (EU) for the treatment of patients with isolated superficial vein thrombosis (SVT), i.e. without concomitant deep vein thrombosis (DVT), of the lower limbs. As part of EU approval, GlaxoSmithKline (GSK) committed to evaluate physicians' adherence to fondaparinux prescribing information regarding proper diagnosis and dosing for the treatment of SVT. The primary objective is to evaluate physicians' adherence to fondaparinux prescribing information for the treatment of patients with SVT without concomitant DVT. The study is designed as a non-interventional, retrospective chart review of patients prescribed fondaparinux to treat their SVT. The study will be conducted in several EU countries.
