Filter by:To determine whether D-Dimer testing, using the MDA D-Dimer assay, can be used to simplify the diagnostic process for pulmonary embolism (PE). This will be assessed by performing a cohort study in 1000 patients with suspected PE. To ascertain if an MDA D-Dimer result of less than 0.75 ug/mL FEU obviates the need for further testing and therapy in patients with suspected PE.
The main hypothesis for this study is that the diagnostic approach of pulmonary embolism (PE) by evaluation of clinical probability, D-dimer test dosage and multi-detector helical computed tomography (hCT) is as safe as the classical "approach" using clinical probability, D-dimer test, lower limb compression ultrasonography and multi-detector helical computed tomography. The second hypothesis involves evaluating the role of searching distal, i.e. infrapopliteal, deep venous thromboses (DVTs) in the diagnostic approach of pulmonary embolism.
Electrical stimulation of the foot can increase blood flow out of the leg. This increased blood flow can prevent blood clots from forming in the leg veins. Blood clots in the leg veins can break off and form life-threatening blood clots in the lungs. Intermittent external pneumatic (air) compression of the foot is already used to increase blood flow in at risk patients. Hypothesis: Electrical stimulation of the foot increases blood flow out of the legs to the same degree as intermittent external pneumatic (air) compression of the foot.
The purpose of this study is to learn if BMS-562247 can prevent blood clots in the legs and lungs in men and women following unilateral total knee replacement surgery. The safety of this treatment will also be studied.
To develop a clinical prediction rule to identify patients with acute pulmonary embolism who are at very low risk for short-term adverse outcomes.
Patients diagnosed with pulmonary embolism (blood clot in the lung) or deep vein thrombosis (blood clot in a leg vein) are at risk for these blood clots to reoccur. Anticoagulant (blood-thinning) drugs are normally given immediately after the clot is discovered and are continued for a period of 3 or 6 months during which time the risk for recurrence is highest. Research has shown that when oral anticoagulants are used appropriately during this period, patients are less at risk for a recurrent blood clot and this risk reduction outweighs the potential for bleeding to occur. In this study, patients who had a blood clot in the lung or in a leg vein and completed 6 months of treatment with daily oral vitamin K antagonists (acenocoumarol or warfarin) or once-weekly injections of SR34006 (a new anticoagulant drug) will receive an additional 6 months of once-weekly SR34006 injections or injections of a solution containing no drug (placebo). This trial will evaluate whether patients treated for an additional 6 months with SR34006 have fewer recurrences of blood clots when compared to patients treated with placebo. Assignment to either SR34006 or placebo will be purely by chance. Neither the patients nor their doctors will know which treatment is being given.
Patients who have a pulmonary embolism (blood clot in the lung) will be treated in this study. The purpose of the study is to compare the safety and effectiveness of a new injectable anticoagulant (blood-thinning) drug, SR34006, with the standard way of treating a pulmonary embolism. The standard treatment includes injections or infusions of an anticoagulant drug, (LMW)heparin, for about a week followed by anticoagulant tablets (warfarin or acenocoumarol) which are taken by mouth. Assignment to either SR34006 or (LMW)heparin plus warfarin or acenocoumarol will be purely by chance and will be known by both patients and their doctors.
Deep venous thrombosis is the presence of blood clots, usually in the legs that lead to either local problems or breathing problems if the clot moves to the lungs. This study is designed to assess both clinical conditions as well as common genetic factors that lead to more risk of deep venous thrombosis. Clinical conditions of venous thrombosis include: stroke, malignancy, and situations such as surgery, pregnancy, trauma, or travel.
To determine the value of contrast enhanced spiral computed tomography (spiral CT) for the diagnosis of acute pulmonary embolism (PE).
To identify the incidence cohort of Olmsted County Minnesota residents with deep venous thrombosis (DVT)/pulmonary embolism (PE) from 1966 through 1990. Episodes of DVT or PE acquired during hospitalization or in the community were identified for future studies.
