Filter by:Anticoagulation is the most important treatment for pulmonary thromboembolism (PTE). The thromboembolism risk is especially high in patients with chronic obstructive pulmonary disease (COPD) exacerbations. However, there's no agreement on the most appropriate duration of anticoagulation in COPD with PTE to balance the risk of recurrence of thrombosis and bleeding. This randomized, controlled trial aims to evaluate the risk and benefit of prolonged anticoagulation compared with the regular 3-month anticoagulation in COPD with PTE.
Chronic obstructive pulmonary disease (COPD) is closely related to venous thromboembolism (VTE). But it is difficult to identify VTE in COPD patients in clinical practice. Therefore, the prevalence data of PTE in COPD is limited. Pulmonary thromboembolism (PTE) is an important factor effecting patients outcomes, but existing researches only have short follow-up time less than 1 year. This study aim to develop an early detection system of PTE in COPD and explore the disease course and prognosis.
After reports from observational studies suggesting an association between acutely ill medical patients and venous thromboembolism (VTE), interventional trials with anticoagulants drugs have demonstrated a significant reduction of VTE during and immediately after hospitalisation. Although several guidelines suggest the clinical relevance of reducing this outcome, there is a low tendency to use anticoagulants in patients hospitalised for acute medical illness. This observational multicentre study wants to evaluate the incidence of venous thrombo-embolism in acutely ill patients hospitalized in internal medicine wards.
This is an open label, multi-center, and randomized phase II trial designed to compare the safety and efficacy of direct oral anticoagulants and subcutaneous dalteparin in patients with acute venous thromboembolism and upper gastrointestinal, hepatobiliary, or pancreatic cancer, based on a group sequential design. Enrolled patients will be randomized in a 1:1 ratio. Patients will be stratified by performance status, type of cancer, chemotherapy and medical centers.
No randomized head-to-head comparison between the individual Non-vitamin K Antagonist Oral Anticoagulants (NOAC) exists. The DANNOAC-VTE study is a nationwide cluster randomized cross-over study comparing efficacy and safety of the four NOACs, edoxaban, apixaban, rivaroxaban and dabigatran for oral anticoagulation in venous thromboembolism across Danish hospitals.
The aim of the study is to make a validation of Caprini score in patients undergoing varicose veins surgery, especially endovascular procedures (endovascular laser treatment - EVLT, radiofrequency ablation - RFA, ultrasound-guided foam sclerotherapy - USFS) and to identify patients with elevated risk of postoperative venous thromboembolism (VTE) who will benefit from prophylactic anticoagulation.
This is a prospective, randomized vanguard trial of trauma patients admitted to the trauma surgery service at Intermountain Medical Center who are deemed to be at high risk for venous thromboembolism. Once identified and enrolled, subjects will be randomized to receive bilateral lower extremity duplex ultrasound surveillance versus no surveillance. The study will compare the two groups with regard to deep vein thrombosis, pulmonary embolism, and major and clinically relevant bleeding episode rates, both during the index hospitalization and at 90 days post-discharge.
Epidemiological data on pulmonary embolism (PE) in China needs to be updated and reported. The China Pulmonary Thromboembolism Registry Study (CURES) is designed to provide the cross-sectional spectrum and chronological trends of PE in China, as well as to reveal the intrinsic etiology and pathogenesis of the disease. The CURES is an ongoing large prospective multicenter registry, which was originally initiated in January 2009 via enrolling suspected or confirmed PE or PE with DVT (deep venous thrombosis) patients and assessed their in-hospital outcomes from 100 medical centers in the China PE-DVT network. As of July 2011, in order to determine the PE-relevant short-term outcomes, enrolled participants were followed-up for at least three months in a longitudinal manner. Since August 2016, with the launch and development of precision medicine research scheme in China, the main principle investigators of CURES decided to collect enrolled patients' blood samples with regular follow-ups every three or six months for at least two years (for long-term outcomes). The study protocol has been approved by the China-Japan Friendship Hospital ethics committee, and all collaborating centers received approvals from their local ethics committee. All patients provided written or verbal informed consent to their participation.
The aim of this study is to overcome the current limits of the scoring systems used to predict both the thrombotic (VTE) and hemorrhagic (BLD) risk for the patient. The main problem of these scoring systems is due to the high rigidity related to the score assigned at each risk item. The presence of an item assigns the full score for that item, without the possibility to moderate that item's score. The final class of risk, for the patient, is the sum of the scores of the selected items. The approach used for the assessment is based on the presence or absence of certain items that will be summed. Starting from scoring system currently used for VTE (PADUA, CAPRINI, KHORANA) and also for BLD (IMPROVE), we will integrate all common items in a single scoring system managed by risk management algorithms that can identify the different classes of risk.
The Computerized Registry of Patients with Venous Thromboembolism (RIETE) is a multidisciplinary Project initiated in march 2001 and consisting in obtaining an extensive data registry of consecutive patients with venous thromboembolism. The main objective is to provide information on the Internet to help physicians to improve their knowledge on the natural history of thromboembolic disease, particularly in those subgroups of patients who are usually not recruited in randomized clinical trials (pregnant women, elderly patients, disseminated cancer, severe renal insufficiency, patients with contraindications to anticoagulation therapy, extreme body weight, etc), with the purpose of decreasing mortality, frequency of thromboembolic recurrences as well as bleeding complications and arterial events. As an additional objective RIETE is also aimed to create predictive scores that help physicians to better identify patients with high risk of presenting some of these complications. The primary parameters recorded by the registry comprise details of each patient's clinical status, including any coexisting or underlying conditions, and the type, dose, duration and outcome (during the first 3 months of therapy) of antithrombotic treatment. Study endpoints are clinically recognized (and objectively confirmed) recurrences of VTE, major and minor bleeding complications, and death.
