Filter by:Following the findings of the clinical trials in drug development, this global non-interventional cohort field study will investigate rivaroxaban under clinical practice conditions in comparison with current standard of care for patients with acute deep vein thrombosis (DVT). The main goal is to analyze long-term safety in the use of rivaroxaban in the treatment of acute DVT in routine clinical practice.
Epidemiological studies have shown a 2-3 fold increased long-term risk of arterial cardiovascular disease after venous thrombosis, most predominant in the first year following initial venous thrombosis. The results of recent observational studies that showed 40-50% risk reductions for first venous thrombosis occurrence when using a statin are in this aspect promising. The results are also somewhat surprising, because the mechanism behind this effect is unclear. Dyslipidemia may be the most plausible explanation to be considered. However, as dyslipidemia is not related to an increased risk of venous thrombosis, it is unlikely that statins decrease venous thrombosis risk by lipid lowering activities. Recent observations indicate that coagulation can activate the initial formation of atherosclerosis. Our hypothesis is therefore that the coagulation profile in persons with venous thrombosis is improved when using a statin, ultimately leading to less atherosclerosis: another well known property of statin use.
Whereas thrombus aspiration in patients with ST-elevation myocardial infarction (STEMI) is recommended by current guidelines, there are insufficient data to unequivocally support thrombectomy in patients with non-STEMI (NSTEMI). The Thrombus Aspiration in ThrOmbus containing culpRiT lesions in Non-ST-Elevation Myocardial Infarction (TATORT-NSTEMI) trial is a 400 patient, prospective, controlled, multicenter, randomized, open-label trial. The hypothesis is that under the background of early revascularization, adjunctive thrombectomy in comparison to conventional percutaneous coronary intervention (PCI) alone leads to less microvascular obstruction (MO) assessed by cardiac magnetic resonance imaging (CMR) in patients with NSTEMI. Patients will be randomized in a 1:1 fashion to one of the two treatment arms. The primary endpoint is the extent of MO assessed by CMR. Secondary endpoints include infarct size and myocardial salvage assessed by CMR, enzymatic infarct size as well as angiographic parameters, such as Thrombolysis in Myocardial Infarction-flow post-PCI and myocardial blush grade. Furthermore, clinical endpoints including death, myocardial reinfarction, target vessel revascularization and new congestive heart failure will be recorded at 6 and 12 months. Safety will be assessed by bleeding and stroke. In summary, the TATORT-NSTEMI trial has been designed to test the hypothesis that thrombectomy will improve myocardial perfusion in patients with NSTEMI and relevant thrombus burden in the culprit vessel reperfused by early PCI.
This study plans to learn more about what is the best treatment to prevent blood clots in patients in intensive care units (ICU's). The investigators know that patients who are in ICU's have a higher than normal risk of getting blood clots in the veins of their arms or legs. This can be very dangerous as the clot may move into the lungs. To prevent this, the standard treatment is to give low dose heparin subcutaneously 3 times a day (usually 5000 units at each dose). In this study the investigators are randomizing patients to receive either standard of care or low dose intravenous heparin in a continuous infusion.
The presence of clots in the veins of arms and/or legs or lungs of Cancer patients decreases their quality of life, delays their treatment and may cause death. The best way to avoid new clots is by giving blood thinners before clots are formed, but even some patients who are taking blood thinners may form blood clots. A major problem is that it is difficult to know which patients form clots while they are receiving blood thinners, a situation called treatment failure. Several studies have shown that by doing blood tests that measure the formation of clots, the investigators could know if the patient is responding to the blood thinners. If this is proven, the investigators will be able to apply these tests to all patients.
Post thrombotic syndrome (PTS) is a frequent and burdensome complication of proximal deep-vein thrombosis.Therapeutic options for PTS are limited and mainly rely on its prevention. Therapeutic trials evidenced that elastic compression stockings (ECS) applying 30-40mmHg of pressure at the ankle reduced the rate of PTS by 50%. Although ECS are unlikely to cause harm, in clinical practice, compliance to this treatment appears to be low as ECS may be difficult to apply and to wear. ECS with a lighter compression strength (20-30mmHg) might be easier to apply and be more comfortable. This could favor a better compliance. CELEST is a randomized, multicentre, double-blind trial which aims to determine whether ECS applying 25mmHg of targeted pressure at the ankle are non inferior to ECS applying 35mmHg of targeted pressure at the ankle
This is a randomized-controlled clinical trial that will randomize 120 patients undergoing clinically-indicated coronary artery bypass graft surgery to prasugrel at a dose of 10 mg daily or matching placebo for 12 months, starting at the time of hospital dismissal from surgery. The primary goal of the study is to determine whether prasugrel administration will prevent thrombus (clot) formation within a saphenous vein graft at 12 months, as examined by optical coherence tomography.
The study aims to document the flow of German patients with cancer and acute deep vein thrombosis from first visit to diagnosis and treatment, the applied diagnostic procedures, and therapy modalities.
This is an observational study to analyze the influence of surgery duration and tourniquet time in the incidence of deep venous thrombosis (DVT) in patients that had undergone total knee arthroplasty (TKA).
Therasphere will be administered via catheter through the Hepatic Artery to treat patients with Hepatocellular Carcinoma and Portal vein Thrombosis.
