Active clinical trials for "Embolism"

Cancer increases the risk of deep vein blood clots and clots traveling to the lungs (emboli) which cause morbidity (leg swelling, pain, and shortness of breath), sudden death, delays cancer treatment, and decreases cancer survival by 66% compared to similar cancer patients without blood clots. Blood thinners may prevent clots but major bleeding is also a problem, so preventive therapies are not used routinely. Identifying patients at highest risk for clots is critical. A tool exists but it has not been used outside of research. We propose to study how to apply this tool in clinical practice and test if it works.

Venous thromboembolism (VTE) remains a leading cause of death in trauma patients. Based on the EAST Management Guidelines for the prevention of VTE in trauma patients, a number of research questions could be addressed by a thorough current literature review combined with a multicenter concurrent analysis. This proposal seeks to create a data registry of trauma patients from multiple trauma centers around the United States that will serve as a platform for the study of VTE.

To assess the safety and efficacy of outpatient treatment using fondaparinux and oral Vit K antagonist, warfarin (Coumadin) in patients with stable acute pulmonary embolus (APE)when initial therapy is administered in the hospital. Prospectively validate risk stratification criteria for predicting patient suitability for outpatient treatment of acute pulmonary embolism.

Number, type and incidence of adverse events/suspected adverse drug reactions in patients treated with apixaban, according to therapeutic indications approved in Mexico.

This multicenter international prospective cohort study will include patients with AIS with a known or newly diagnosed anticoagulant-naïve AF. All centers will use the same transcranial Doppler machine for one-hour monitoring with bilateral 2-MHz probes within 24 hours of symptom onset. Recordings will be analyzed for MES by a blinded central reader. The primary aim is to determine the proportion of patients with MES and the association of MES with functional outcomes assessed by a modified Rankin scale (mRS) score at 90 days.

This is a retrospective observational study to describe the sociodemographic and clinical characteristics of patients diagnosed with non-valvular atrial fibrillation (NVAF) at risk of stroke or systemic embolism, who at least three months ago changed their anticoagulant therapy, due to any clinical situation, and are currently on treatment with a direct oral anticoagulant (DOAC)

This study aims to collect patient reported outcomes and assess treatment satisfaction in active cancer patients treated with rivaroxaban for VTE (venous thromboembolism).

Postoperative venous thromboembolism (VTE) is a significant health-care problem, resulting in significant morbidity, mortality and resource utilization. The true incidence is unknown, and may range from 1% to 15%. At the current time, the clinical practice of VTE prophylaxis in thoracic surgery includes administration of unfractionated or low molecular weight heparin starting at the perioperative period and finishing at the time of patients' discharge. In orthopaedic surgery, prolonged thromboprophylaxis beyond 10 days and up to 35 days has become the standard of care. There is a clear need to systematically evaluate the incidence of VTE after resection of lung malignancies and to evaluate the role of extended VTE prophylaxis in preventing Deep Vein Thrombosis (DVT) and pulmonary embolus (PE) after those major lung resections. This study will involve patients undergoing lung resection for malignancy at St. Joseph's Healthcare Hamilton and the University Health Network's Toronto General Hospital. The study will include 150 consecutively recruited patients. Study interventions will include Computed Tomography with pulmonary embolus (PE) protocol and bilateral extended leg Doppler Ultrasound for the detection of Deep Vein Thrombosis 30 days post-surgery. In summary, this study is aimed at evaluating, for the first time in a prospective manner, the actual incidence of DVT and PE in patients undergoing major lung resections for malignancies. The knowledge gained in this study will be used to inform a future investigation involving a Randomized Controlled Trial (RCT) to compare current post-operative thromboprophylaxis with an extended 30-day prophylaxis protocol with the hope of providing an evidence-based practice change in VTE prophylaxis care for this high risk population.
