Filter by:- The purpose of this study is to compare effectiveness and safety of warfarin and apixaban among non-valvular atrial fibrillation (NVAF) patients at higher chance of bleeding using a Japanese nation-wide administrative claims database. - Atrial fibrillation (AF) is characterized by a fast, irregular heartbeat which can cause blood to pool in the atria and increase the chance of the formation of blood clots. - An anticoagulation therapy is a critical treatment to prevent thromboembolism in NVAF patients. - Apixaban was demonstrated superiority compared to warfarin in preventing stroke or systemic embolism, caused less bleeding, and resulted in lower mortality in patients with AF in Phase 3 clinical trial. - Previously we have shown that bleeding risks as well as stroke/SE risks are less in real world clinical practice in Japan compared to warfarin. However there are limited apixaban data for Japanese NVAF patients with high bleeding risk(s). - This study will evaluate the risk of stroke/systemic embolism as well as the risk of bleeding in the real world settings in Japanese patients with NVAF who has higher chance of bleeding
The objective of this study is to investigate safety and effectiveness of apixaban compared to warfarin in very elderly patients with Non-valvular atrial fibrillation (NVAF). In addition to the absolute age, effects on higher age-related risk factors on relative risk of apixaban to warfarin is also investigated through subgroup analyses.
The purpose of this study are 1) to characterize the primary and secondary prevention patients, 2) to calculate incidence rates of stroke/SE or major bleeding in each cohort and 3) to investigate for Japanese secondary prevention patients as Real World Evidence (RWE) on the effectiveness and safety of apixaban compared to warfarin in patients with non-valvular atrial fibrillation (NVAF).
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.
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.
An anticoagulation therapy is a critical treatment to prevent thromboembolism in non-valvular AF (NVAF) patients. Warfarin, a vitamin K antagonist, is the first oral anticoagulant approved for the treatment for prevention of thromboembolism and it had long been the only oral anticoagulant until the first non-vitamin K antagonist oral anticoagulants (NOACs). However, its safety and effectiveness remains unknown in real-world clinical practice in Japan
