Filter by: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 investigate venous thromboembolism in two carefully conducted prospective epidemiologic studies of African American and white adults -- the Atherosclerosis Risk in Communities (ARIC) Study and the Cardiovascular Health Study (CHS).
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.
To determine the relationships of hormonal, reproductive, dietary, and lifestyle factors, as well as biochemical and genetic factors, with the subsequent risk of coronary heart disease and other cardiovascular events in a cohort of female registered nurses. The current funding cycle involves comprehensive metabolomic profiling of coronary heart disease cases and controls and development of metabolomic risk scores for coronary heart disease.
To evaluate the sensitivity and specificity of two major, widely used technologies, radionuclear imaging (ventilation-perfusion scanning) and pulmonary angiography, for the diagnosis of pulmonary embolism.
