Filter by:AECOPD increases the risk of VTE.VTE prevention is a long way to go for high-risk VTE patients in China.The incidence of AECOPD complicated with VTE in Asian population is high and the mortality rate is high.Rivaroxaban, a new oral anticoagulant, has been widely used in the treatment and prevention of VTE.However the question about the efficacy and safety of new oral anticoagulant compared with LMWHs for the prevention of symptomatic VTE and VTE-related death post-hospital discharge in high-risk AECOPD patients is still unknown. Thus this study is to evaluate if the prophylactic anticoagulation effect by Rivaroxaban is non-inferiority than Enoxaprine in high risk AECOPD and to evaluate the safety of using Rivaroxaban to prevent VTE in high risk AECOPD comparing with Enoxaprine.
Venous thromboembolism (VTE) including deep vein thrombosis (DVT) and pulmonary embolism (PE) affects about 1,200,000 individuals each year in Europe. About 50% of VTE are unprovoked and 20% of these patients will face a recurrent event after the usual three to six‐month course of anticoagulant treatment. To date, most patients are given prolonged anticoagulant treatment. However, anticoagulant treatment are associated with a major risk of bleeding (3%/year). Thus an accurate identification of patients with unprovoked VTE with a low risk of recurrence is needed to avoid unnecessary anticoagulant treatment with a risk of bleeding. Over the past few years, microparticles (MPs) which are small vesicles originating from the budding of cellular membranes have emerged as important biological entities regulating hemostasis. MPs expose at their surface procoagulant molecules such as phosphatidylserin and tissue factor (TF). All data obtained in mouse models support a role of MPs in venous thrombosis mediated by the TF activation. Moreover, results from clinical studies showed that TF-MPs was associated with the risk of venous thrombosis. However, the predictive value of TF-MPs in the recurrence of VTE is unknown. Besides, no study has taken into account the recent progresses in the understanding of the role of MPs in haemostasis. Indeed, MPs vectorize molecules which are not only procoagulant but also profibrinolytic. The net result depends on a balance between both activities (the coagulo-lytic balance). This balance is can be measured by two complimentary assays on MPs. We hypothesized that the coagu-lytic balance of MPs is associated with an increased risk of VTE recurrence after stopping the anticoagulant treatment.
REMMITE, a retrospective and prospective registry with one-year follow-up, will provide valuable insights into the clinical diagnosis, management, treatment trends as well as related outcomes of three cohorts: DVT, DVT-PE, PE patients throughout many regions of Mexico and through different health care systems.
The purpose of this study is to evaluate women with heavy menstrual bleeding that have venous thromboembolism or atrial fibrillation. There will be a comparison of the anti-coagulants; drugs rivaroxaban or apixaban to see if one of the drugs works better to control bleeding during the women's menses.
TACT is a "real world" randomized controlled trial of tecarfarin, a novel vitamin K antagonist, vs. warfarin. The quality of anticoagulation control will be compared for the two groups of subjects who require chronic oral anticoagulation for a broad panel of indications.
The principal aim of the present research is to compare two methods of antibiotic delivery: concomitant tumescent antibiotic delivery (TAD) and intravenous antibiotic delivery (IVAD) versus IVAD alone, (TAD+IVAD vs IVAD), with respect to the prevention of surgical site infections (SSI). The investigators hypothesize that TAD+IVAD will significantly reduce the incidence of SSI compared to IVAD. TAD is the subcutaneous infiltration of a dilute solution of antibiotic(s) in a solution of tumescent local anesthesia (TLA). TLA consists of a dilute solution of lidocaine (1gm/L), epinephrine (1mg/L) and sodium bicarbonate (10mEq/L) in 0.9% physiologic saline. A secondary aim of this study is to compare TAD+IVAD vs IVAD with respect to the prevention of post-operative venous thromboembolism (VTE).
The Crux Vena Cava Filter (VCF) Registry is a clinical study, sponsored by Volcano Corporation, to evaluate the short and long term performance and clinical outcomes of the Crux Vena Cava Filter System.
The purpose of this study is to investigate the appropriate duration of dabigatran use after radiofrequency catheter ablation for paroxysmal atrial fibrillation in patients with low thromboembolic risk. According to the most recent guideline, anticoagulation is recommended to continue at least 2 months after the procedure. However bleeding risk with anticoagulant is also problematic. Post-procedural thrombosis is considered due to acute inflammation or char formation at the site of ablation, and these reaction occurs mostly within 1 month after the procedure. Also, the risk of thromboembolism is low in patients with CHA2DS2-VASc score less than 1. The investigators hypothesized that dabigatran use for the first 1 month after the RFCA for patients with paroxysmal AF and low thromboembolic risk would be sufficient for efficacy and safety compared to conventional dabigatran use for 2 months.
Patients with an episode of VTE (DVT and / or PE) have a mortality rate of 16-21% at 1 year after diagnosis. Morbidity associated with VTE is marked by the risk of recurrence, estimated at 30% and estimated at 29% after 8 years of follow post-thrombotic syndrome. For a number of these patients, risk factors have been identified (congenital or acquired thrombophilia, cancer, postpartum, surgery, prolonged immobilization, etc..). In 25-50% of cases, the etiology remains unknown, justifying the need for well-conducted studies to determine other potential risk factors. In addition, the expansion of treatment options with the arrival on the market of new direct oral anticoagulants, allows comparative studies on the effectiveness and frequency of adverse events for each treatment.
Since 2003, that the first retrievable IVC filter was introduced in the U.S,improvements have been made in the filter design to resolve problems of structural integrity and increase the ability to remove the filter after longer periods of time.The FDA issued a communication in August 2010 advising physicians to remove retrievable filters whenever possible and updated that letter again in May 2014 due to concerns that these retrievable IVC filters, intended for short-term placement, are not always removed once a patient's risk for PE subsides. Known long term risks associated with IVC filters include but are not limited to lower limb deep vein thrombosis (DVT), filter fracture, filter migration, filter embolization and IVC perforation.
