Active clinical trials for "Thrombosis"

Comparison Study of CoaguChek XS PT and Laboratory Innovin PT by NTUH Lab Medicine

The purpose of the study is to evaluate patients with inferior vena cava (IVC)thrombosis in terms of etiology, clinical course and prognosis during long-term follow-up. Patients with isolated lower extremity DVT, matched for age and gender, serve as controls.

Migraine was described as related to stroke in adults and children as well. Complete thrombophilic status was not study in large groups of pediatric patients. The purpose of our study is to assess the prethrombotic profile among children and teenagers diagnosed as suffering from migraine attacks.

To perform a randomized clinical trial comparing continuing one month of treatment with heparin in patients with deep venous thrombosis to standard care using heparin for five days and oral warfarin for three months.

Hospital-acquired venous thromboembolism (HA-VTE) is one of the leading preventable causes of in-hospital mortality, but prevention of VTE in hospitalized medical patients remains challenging, as preventive measures such as pharmacological thromboprophylaxis (TPX) need to be tailored to individual thrombotic risk. The broad objective of this project is to improve VTE prevention strategies in hospitalized medical patients by prospectively examining VTE risk factors (including mobility) and comparing existing risk assessment models.

Background: venous thromboembolism (VTE) is a common complication in critically ill patients, admitted to the Intensive Care Units (ICUs). At the present time, there is no validated score to estimate risks and benefits of antithrombotic pharmacological prophylaxis in this subset of patients. Aim of the study: investigating potential harms and benefits of a protocol for systematic screening of DVT in critically ill patients, admitted to an ICU. Expected relevance: systematic screening for deep vein thrombosis (DVT) through ultrasound (US) lower limb veins examination could help defining the indication to antithrombotic pharmacological treatment, but no protocol of systematic screening has been validated so far. Furthermore, the screening could be associated with over-diagnosis and consequent over-treatment, as well as increased management burden for the caregivers and higher healthcare costs.

To investigate the predictive value of inflammatory indexes and CHA2DS2-VASc score for anterior myocardial infarction (ANT-MI) with left ventricular thrombus(LVT) (LVT).

The objective of this study is to compare oral rivaroxaban with injectable enoxaparin in orthopaedic trauma patients to determine if orally administered rivaroxaban once daily carries greater compliance and overall satisfaction than enoxaparin self-administered by subcutaneous injection once daily.

Blood clots occurring in the legs and in the lungs are relatively common; they occur in around 3 in a 1000 people per year. They can cause disability and are also potentially life threatening. When a clot occurs in the legs it is called a deep vein thrombosis or DVT. When they occur in the lungs they are called a pulmonary embolism or PE. The risk for DVT and PE is higher in people with conditions which cause inflammation. The most common of these are inflammatory bowel disease (ulcerative colitis and Crohn's disease), rheumatoid arthritis, and psoriatic arthritis (a condition comprised of psoriasis and joint inflammation). What is not known is how much higher the risk of DVT and PE is in these groups compared with people without inflammatory disease, and what causes the excess risk in these people. This study aims to assess the measure the exact increase in risk for DVT and PE in people with these inflammatory conditions and to identify which risk factors are most strongly associated with the increased risk. These data should help with an understand the causes of blood clot risk in these inflammatory conditions and in identify targets for reducing risk.

Research questions: What is the absolute risk reduction for in-hospital major adverse cardiac events (MACE) associated with the use of dual anti-platelet therapy as compared with aspirin alone in this population? What is the absolute risk increase for clinically significant bleeding during the same period associated with the use of dual anti-platelet therapy as compared with aspirin alone in this population? In brief the design of the study is as follows: We will study patients undergoing non-cardiac surgery within four years of coronary stenting. We will record the anti-platelet agents taken by patients before, during and after surgery. We will record cardiac and bleeding events that occur whilst the patient is in hospital. We will use the statistical technique of propensity scoring to match patients who have similar risk factors and who received different anti-platelet regimens. We will compare the incidence of cardiac events and bleeding in the matched groups.
