Filter by:This is an observational registry study aiming to collect data on efficacy and safety of the single chamber Biotronik DX system with enhanced atrial diagnostics. The minimal follow-up period is 24 months. All analyses on the data will be done post-hoc; the study does not intend to confirm any pre-specified hypotheses.
The purpose of this study is to determine that a new drug called "Rivaroxaban®" is effective in preventing patients from forming clots after their heart rhythm has been reset by the cardiologist with an electrical device.
Can thrombin generation measurement predict the risk of venous thromboembolism in acute ill patients Traditional coagulation tests do not assess the whole coagulation system. Thrombin generation assays measure the ability of plasma sample to generate thrombin following in vitro activation of coagulation. In contrast to the classical clotting assays, thrombin generation reflects and integrates all pro and anticoagulant reactions that regulate the formation and inhibition of thrombin. The aim of our study is to investigate whether thrombin generation would be able to predict a hypercoagulable state in acute ill patients admitted in the internal medical departments and how it correlates with the Padua prediction score, a score that could assists the risk for venous thromboembolism in hospitalized medical patients. In total 300 patients are planned for inclusion in this trial. After signing an informed consent a blood sample will be obtained from each participant. We will measure the thrombin generation over time in plasma assessed by the calibrated automated thrombogram (CAT).
The rate of venous thromboembolic events in trauma patients at high risk for deep vein thrombosis and pulmonary embolism receiving low dose unfractionated heparin every 8 hours will be equivalent or less than a similar group of patients given a standard every 12 hour dose of low molecular weight heparin.
In this study the investigators want to look at whether using aspirin instead of rivaroxaban (after initial treatment with rivaroxaban) works as well at preventing blood clots while also reducing risk of bleeding and is more cost effective in patients who have either a total hip replacement or total knee replacement.
The objective of this observational study is to characterize long-term (5 years post event) clinical outcomes in patients who experienced a thromboembolic event (TEE) during participation in the GSK ENABLE clinical trials. Patients eligible for the study are patient who experienced a TEE during participation in the ENABLE trials. Each included patient will be followed for a period of 5 years from the date of their first TEE. Demographic and clinical characteristics will be collected for the index date (time of TEE) and every sixth month during the follow-up period, information will be collected for the outcomes of interests: mortality, new TEE, hepatic decompensation, evaluation for liver transplant and result of evaluation, and liver transplantation. All information will collected by medical record review.
The purpose of this study is: - To assess the safety and efficacy profile of ISIS-FXIRx, including incidence of bleeding and VTE, in patients undergoing total knee arthroplasty. - To compare the efficacy and safety profile of ISIS-FXIRx in patients who achieve less than or equal to 0.2 U/mL FXI activity levels to that of enoxaparin.
CV185118 is a single dose Apixaban PK/PD study in pediatric participants. The objective of this study is primarily to study the PK/PD of Apixaban in pediatric participants at risk for thrombosis
This is a research study to compare the efficacy of aspirin (acetylsalicylic acid) and pneumatic compression devices versus enoxaparin (also known as Lovenox) and pneumatic compression devices in preventing deep vein thrombosis in patients with pelvic and lower extremity malignant tumors and undergoing surgery. Pneumatic compression devices are also known as sequential compression devices and are inflatable compression sleeves that are placed around patient's legs to reduce the risk of clot formation deep vein thrombosis. Pneumatic compression devices are made of a soft material that wraps around the lower leg and periodically squeeze the calf. A deep vein thrombosis is a blood clot. Most hospitalized patients wear these as a preventive measure. Pneumatic compression devices alone are not sufficient to prevent deep vein thrombosis formation. Therefore, medicines, such as aspirin and enoxaparin are utilized. Both drugs are used for prevention, but there are no studies in patients with musculoskeletal tumors which have determined whether one drug is better than another. The knowledge gained from this study will determine whether aspirin and pneumatic compression devices is the same or better than enoxaparin and pneumatic compression devices in preventing deep vein thrombosis in this patient population and may result in fewer wound and bleeding complications
Over 100,000 VHA patients receive anticoagulants (blood thinners) each year to prevent blood clots (including strokes). Too much anticoagulation increases the risk of serious or even fatal bleeding, and too little anticoagulation fails to protect the patient against blood clots. VHA anticoagulation clinics vary widely on how much time their patients spend in the therapeutic range, the range within which they are protected from clots but not at excessive risk of bleeding. Anticoagulation clinics can improve anticoagulation control by following several relatively simple procedures, including following-up promptly when patients are out of range and focusing on educating and supporting patients with poor control. In this study, the investigators will promote these practices at the anticoagulation clinics of the New England VA region, with a goal of improving anticoagulation control.
