Active clinical trials for "Thrombosis"

Pediatric thrombosis is multifactorial, and usually risk factors either congenital or acquired are present. Patient may has one risk factor or more such as sepsis, cancers, congenital heart disease, post surgery , central venous catheter insertion, nephrotic syndrome, systemic lupus erythromatosis and inflammatory bowel disease. If there's no obvious risk factor for thrombosis, hereditary thrombophilia is suspected which results when an inherited factor, such as antithrombin , protein C or protein S deficiency.

To investigate the safety and pharmacokinetics of apixaban in children with congenital or acquired heart disease who have a need for anticoagulation.

The PREVENTER Trial aims to compare the use of perioperative pharmacologic prophylaxis (subcutaneous heparin) with intermittent pneumatic compression devices (IPCs) to the use of IPCs alone for the prevention of venous thromboembolism (VTE) after radical prostatectomy (RP).

This study evaluates two different methods for monitoring a patient's anti-clotting [heparin] therapy after they receive a heart pump implant [left ventricular assist device -LVAD]. One method tests for how long it takes the patient's blood to clot and uses that to determine if they are on the right dose of heparin. The other method uses a more direct measure of how much heparin is in the blood. The hypothesis is that the method that more directly measures how much heparin is in the patient's blood will provide better medical results for the patient's care after they have the heart pump implant. To that end, the investigators are conducting this feasibility trial to establish the logistics associated with the implementation of these heparin monitoring approaches.

Patients with acute ST-segment elevation myocardial infarction (STEMI) have an elevated risk of stroke, most of which are cardio-embolic in origin as a result of left ventricular (LV) thrombus formation. Anterior-wall location of a MI, in particular, can lead to the complications of LV aneurysm and/or thrombus, which some estimate occurs in approximately up to one-third of individuals within the first 2 weeks following an anterior MI. In the absence of anti coagulation, the risk of embolization in patients with a documented LV thrombus has been reported to be between 10 and 15 percent [3]. Although there are no randomized trials evaluating the efficacy of anticoagulation in patients with an LV thrombus after MI, observational studies provide substantial supporting evidence for the recommendation to anticoagulate patients with documented LV thrombus in order to reduce the risk of embolization. The observation that most events occur within the first three months from the MI forms the basis for the recommendation that anticoagulant therapy should be started early and continued for at least three to six months after myocardial infarction. Currently the practice guidelines recommend anticoagulation after MI only in certain settings such as the presence of LV thrombus or atrial fibrillation. To date there are no data on the use of novel oral anticoagulants (NOACS) for stroke prevention in the setting of LV thrombus after acute MI. The proposed aim of this randomized open label non inferiority clinical trial is to assess whether apixaban is as effective as VKA for the treatment of LV thrombus after acute ST segment elevation MI. Population: Patients with evidence of LV thrombus as assessed by trans-thoracic echocardiography (TTE) 3 to 7 days post admission for acute ST-elevation MI Intervention: The patients will be randomly assigned to treatment with apixaban or s.c enoxaparin 1mg/Kg BID followed by dose-adjusted warfarin to achieve a target international normalized ratio (INR) of 2.0 to 3.0 for 3 months. The study Outcomes are the presence of LV thrombus as assessed be echo, major bleeding, and stroke or systemic embolism and death from any cause.

To evaluate the benefits of Ayurvedic SUVED & REIMMUGEN Colostrum for reduction/reversal of symptoms and study clinical progress in Vascular disease; CAD, CAV, Stroke, DVT patients.

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.

SECRET examines the safety of rivaroxaban versus standard-of-care for treatment of symptomatic cerebral venous thrombosis, initiated within 14 days of diagnosis.

The purpose of this study is to find out whether rivaroxaban is safe to use in children and how long it stays in the body. Safety will be assessed by looking at the incidence and types of bleeding events. There will also be a check for worsening of blood clots.

Purpose: Warfarin is now the most commonly used oral anticoagulant. This drug has inter-individual variability due to the genetic polymorphisms in the warfarin metabolizing enzyme, CYP2C9 and warfarin target, VKORC1. The investigators' team developed a pharmacogenetic dosing algorithm which can predict patients required warfarin dose, thus could prevent warfarin induced warfarin adverse events. Methods: The investigators recruited patients with indications for warfarin, the genotypes of VKORC1 and CYP2C9 were determined by the hospitals and verified by National Center for Genome Medicine. The investigators then randomized the patients to one of three arms: 1. Warfarin dose predicted by dosing algorithm developed by the International Warfarin pharmacogenetic Consortium (IWPC), 2. Algorithm developed by the Taiwan Warfarin Consortium and 3. Standard of care. The investigators aimed to determine whether using genetic dosing algorithm can lead to more stable dose and safer use of the drug.
