Active clinical trials for "Thromboembolism"

Patients receiving Novel Oral Anticoagulation (NOACs) undergo diagnostic and therapeutic procedures at a rate of 10% per year. Short half-lives and rapid onset of action allow for short periods of NOAC interruption without heparin bridging. There is only minimal information on the peri-procedural usage pattern of edoxaban and the related outcome data currently available. Therefore, further real-world clinical data on the peri-procedural usage pattern of edoxaban within any diagnostic or interventional procedure in patients with non-valvular atrial fibrillation (NVAF) or venous thromboembolism (VTE) will be collected in this registry.

The aim of this study is to verify if patients admitted to hospital in a medical division and in the intensive care unit for a COVID-19 infection are at higher risk of developing a VTE complication and if they actually present an increased hypercoagulable state.

The aim of the study is to investigate the existence of clonal hematopoiesis of indeterminate potential (CHIP) in patients with a history of venous thromboembolism. The study investigators make the assumption that these patients present mutations involved in CHIP occurrence.

Venous thrombo-embolic (VTE) rates could be high in patients with amyotrophic lateral sclerosis (ALS). Indeed, the rate of VTE in this specific population could be 7-fold higher in this population. Predictiv factors of VTE in patients with ALS are mobility reduction and neurological paralysis. However, to our knowledge, medical littérature is poor concerning VTE and ALS association. Our first aim is to define annual rate of VTE in ALS population.Then we aim to identify predictiv factors of VTE in this specific population. The studied population is Brest universitary hospital cohort of ALS patient included between 2000 and 2019.

This study is a retrospective, observational, nationwide population-based cohort study utilizing the South Korea's Health Insurance and Review Assessment Service (HIRA) database. The aims of this study are to describe the sociodemographic and clinical characteristics of patients with venous thromboembolism according to their anticoagulant treatment (parenteral anticoagulants, warfarin, or non-vitamin K antagonist oral anticoagulants), to describe the treatment patterns related to anticoagulants, and to examine the risk of major bleeding according to the specific type of oral anticoagulants. The study will be conducted in two phases: Phase I for descriptive study and Phase II for comparative study.

This is an observational study in which data from the past is collected for a treatment which is already available for doctors to prescribe for venous thromboembolism (VTE). VTE is a condition in which blood clots form in veins, which can lead to disability and death. This study looks at the bleeding risk in Japanese patients who are already receiving long-term rivaroxaban treatment for their VTE. Some common causes of VTE are surgery, lack of movement, being bed-ridden and cancer. VTE that is caused by cancer is called cancer-associated venous thromboembolism (Ca-VTE). The study treatment, rivaroxaban, is a blood thinner prescribed by doctors to help treat conditions like VTE. By thinning the blood, rivaroxaban can help keep blood flowing normally and prevent blood clots. But, rivaroxaban can lead to increased bleeding in some people. There have been studies done in which participants with VTE and Ca-VTE received treatment with rivaroxaban for a long period of time. The overall results of those studies showed that long-term treatment with rivaroxaban helped prevent blood clots in those participants. Some of the participants had increased bleeding after this long-term treatment, while some did not. Participants with certain types of cancers, such as Ca-VTE, also had an increased risk of bleeding. These studies, however, did not include Japanese participants. So, the researchers in this study want to learn more about the risk of bleeding in Japanese patients with VTE or Ca-VTE who receive long-term treatment with rivaroxaban. To do this, the researchers plan to use a medical database to find information for patients with VTE and Ca-VTE who have already been taking rivaroxaban for their condition. This database will help the researchers collect information about the bleeding risk of long-term rivaroxaban treatment in Japanese patients. In this study, the researchers will learn more about: the characteristics of patients with VTE who are treated with rivaroxaban for a period of less than 3 months to more than 1 year the bleeding risk for all of the patients throughout the study the bleeding risk for the patients with Ca-VTE throughout the study the cause of any bleeding that happens The researchers will follow and record these results for Japanese patients from October 2015 to December 2020.

Postoperative Venous Thromboembolism Events (VTE) constitute a major source of morbidity and mortality after surgery. The aim of this study was to investigate whether commonly occurring Single Nucleotide Polymorphisms (SNPs) are associated with VTE in the surgical setting.

This study aims to investigate the incidence of venous thromboembolism in people who are diagnosed with atopic dermatitis.

Oral anticoagulants have a prominent place in the strategy of prevention and treatment of thromboembolic diseases, especially in patients with atrial fibrillation. However, a study conducted by the National Fund for Health Insurance (Caisse primaire d'Assurance maladie, CPAM) in 2017 among nearly 35,000 patients with non-valvular atrial fibrillation showed that one in five patients stopped their oral anticoagulant without medical advice for at least 60 days during the first year of treatment. In our establishment, patients hospitalized in the Cardiology departments and treated with oral anticoagulants benefit from pharmaceutical interviews on their treatment before they return at home. This activity, which exists since November 2014, is based on a team consisting on a pharmacy student, supervised by a pharmacist trained in therapeutic education. In order to secure the management of patients treated by oral anticoagulants and to answer the requirements of Certification, the investigators wish to extend the pharmaceutical interviews to all of hospital's healthcare services. However, the large number of patients concerned, the shorter hospital stays and the difficulties to organize collective sessions in front of the diversity of treatments and diseases are parameters to be taken into account in the development of this activity. The provision of a targeting tool for patients with high risk of thromboembolism and / or hemorrhage is a prerequisite for organizing this institutional approach to support patients on anticoagulants. In this context, the investigators want to establish a prioritization score to identify patients on oral anticoagulants with a higher drug risk.

The purpose of this study is to assess outpatient treatment patterns following hospitalization for venous thromboembolism (VTE). VTE is a condition that occurs when blood clot forms in the vein. This is a retrospective study (assessments on events that have already occurred) of healthcare claims from databases. The study sponsors will assess healthcare claim records of patients treated with either apixaban or warfarin. Assessment includes treatment persistence, switch, and stopping therapy, along with recurrent VTE and bleeding.
