View clinical trials related to Non-valvular Atrial Fibrillation.
Filter by:Atrial fibrillation is a heart condition that causes an abnormal and fast heart rate. For people with non-valvular atrial fibrillation (NVAF), this is caused by problems such as high blood pressure and diabetes. NVAF happens more often in elderly people and can lead to stroke, heart failure, and death. Doctors are currently able to give patients a type of treatment called an anticoagulant. Anticoagulants work by making the blood thinner. They are thought to help reduce the risk of stroke and death caused by NVAF. In this study, researchers wanted to learn more about what elderly people think of taking anticoagulants that do not have any vitamin K in them. These are called non-VKA oral anticoagulants (NOACs). This study will include up to about 150 Belgian men and women aged 75 years and over who have NVAF and have been treated with NOACs. The study will also include about 10 doctors who have treated these patients. In this study, there will be no required tests or visits. Instead, patients will answer a paper questionnaire about their use of NOACs. The researchers will ask the doctors questions about how they treat their patients using NOACs. The main types of questions the researchers will focus on are: - The patient characteristics of the elderly with NVAF who are treated with NOACs - The level of fear of the elderly about bleeding while using a blood thinner and the fear of stroke/thrombosis. - The geriatrician's thoughts about using NOACs to treat NVAF in elderly patients - Those patient characteristics geriatrician's find most important when deciding on the anticoagulation treatment in the elderly patients. The information from this study will be collected between February and April 2021. But, the whole study will take about 6 months to finish and is expected to end in July 2021.
The etiology of the radiation cystitis is a pelvic irradiation generally performed as part of the treatment of prostate cancer. The incidence is 50,000 new cases per year. Approximately 35% of prostate cancer treatment is radiotherapy. The prevalence of haematuric radiation cystitis is 4-5% (about 800 patients). One of the complications of radiation cystitis is persistent hematuria. There is currently no curative treatment for this hematuria. There are few treatment options with a random probability of improvement of this symptomatology. These haematurias are rarely resolved spontaneously and most of the time involve emergency room management with +/- invasive procedures, sometimes by hospitalisation, always with a significant psychological impact on the patient. Furthermore, lifetime anticoagulant treatment considerably increases the likelihood of bladder bleeding. This is the case of patients being followed for Atrial Fibrillation Cardiac Arrhythmia (AFCA), which by definition carries a major cardioembolic risk, and who will be of particular interest in this study. In recent years, cardiologists have developed an alternative to anticoagulants: left atrial appendage closure or left atrial occlusion (LAO) . This procedure consists of inserting a nitinol prosthesis in the left atrium, the site of more than 90% of thrombi formation in non-valvular atrial fibrillation. This minimally invasive procedure lasts about 15 minutes and is performed during a 48-hour hospitalization. Anticoagulants are stopped the day after the setting up procedure. Several studies have shown non-inferiority of atrial closure and anticoagulants to thromboembolic events in non-valvular atrial fibrillation. In addition, LAO allows the permanent discontinuation of anticoagulants, associated with the cessation of anticoagulant bleeding adverse events. While studies have been conducted on the impact of this technique on patients monitored in cardiology, no studies evaluate the value of LAO in anticoagulated patients with a hematuric radiation cystitis. This tprocedure is already used in routine care for patients followed in urology, and has shown encouraging results, since 8 out of 10 patients saw a significant reduction in the number of haematurias, but it has never yet been scientifically proven to be effective, hence the aim of this study. The interest of this study will therefore be : - To evaluate the potential benefit of left atrial appendage closure on the number of episodes of hematuria. - To evaluate the economic benefit in reducing the number of hospitalizations, surgeries and complications for hematuria as well as the discontinuation of anticoagulants. As the patient's data must be retrieved regardless of the patient's subsequent management (with or without a cardiac procedure) within the framework of the HEMOCC protocol, it will be proposed to the patient as soon as he or she is consulting for haematuria on radiation cystitis. The patient will be followed for 3 years. The mainly descriptive analyses will be collected in the form of a register and carried out by a biostatistician from Clermont-Ferrand University Hospital.
This clinical study is a prospective, multi-center, non-interventional study designed to investigate the safety and effectiveness of percutaneous LAA appendage closure by using LAmbre™ Left Atrial Appendage Occluder System. 579 patients with valvular AF complicated with previous AF-related embolic events (including ischemic stroke, TIA and systemic embolism) were enrolled at about 20 study sites nationwide. The baseline data, operation process and relevant follow-up information of subjects were recorded at 7 months after operation or before discharge and at 1, 3, 6, 12 and 24 months after operation.
This study is designed to gain real-world clinical data on the peri- and post-procedural usage of anticoagulation and antiplatelet therapy in patients with non-valvular atrial fibrillation (NVAF) undergoing successful percutaneous coronary intervention (PCI) treated with edoxaban.
This is a prospective, multicenter, randomized, active controlled, clinical trial to evaluate the safety and effectiveness of the LAMax Left Atrial Appendage (LAA) Closure System.
By evaluating routine clinical practice data from the UK primary care database, researchers in this study want to gather information on the kidney function of patients with non-valvular atrial fibrillation (NVAF, irregularly heart beats which is not caused by a heart valve problem) who are treated with Rivaroxaban (non-vitamin K antagonist, brand name Xarelto) or vitamin K antagonists (VKAs). The study planned to enroll about 25,000 male or female patients who were at least 18 years old and were new users of Rivaroxaban or VKAs between 01 January 2014 and 30 September 2019. Researchers are especially interested in whether patients experienced under treatment any worsening in kidney function, the onset of acute kidney diseases or injuries. In addition, risk of worsening in kidney function in patients with or without diabetes or heart failures are of interest to the researchers.
A prospective, single center, open-label, single arm, study to evaluate the safety and technical performance of the CLAAS system for closure of the left atrial appendage.
While it is well known that stopping or changing medication with blood thinners in patients who suffer from non-valvular atrial fibrillation (NVAF) increases the risk of ischemic stroke (a condition which occurs when a vessel supplying blood to the brain is obstructed), bleeding or thromboembolism (a condition that happens when a blood clot forms elsewhere in the body and travels through the blood stream to plug another vessel), limited data are available on the number of NVAF patients and the reasons why NVAF patients in Italy stop or change their treatment with blood thinners to prevent stroke or thromboembolism. By following the NVAF patients in routine clinical practice in Italy who are treated with rivaroxaban to prevent stroke or systemic embolism researchers want to find out how many NVAF patients and for what reasons NVAF patients stopped or changed rivaroxaban treatment. Study data will be collected through patients' routine visits at their treating doctor over a period of 24 months for each patient.
