NCT05232643
The purpose of this study is to provide real-world data useful to address the factors associated to the administration of oral anticoagulants in the elderly population affected by non-valvular atrial fibrillation (NVAF), in Italy, and it's persistence rate after one year.
NCT06606275
This is a retrospective study of End-Stage Kidney Disease (ESKD) patients on dialysis receiving apixaban or warfarin at Tawam Hospital \[a tertiary care hospital in Al Ain, UAE\]. The study aims to assess the appropriateness of prescribing apixaban and warfarin in this population and evaluate their safety and effectiveness.
NCT05022758
This is an observational study in which data collected from the past of patients with non-valvular atrial fibrillation (NVAF) is studied. NVAF is a condition in which patients suffer from irregular and often rapid heartbeats which are not caused by a heart valve problem. NVAF can lead to thromboembolism, a condition that happens when a blood clot forms in the body and travels through the blood stream to plug another vessel. To prevent thromboembolism doctors often prescribe a blood thinner medication. In patients with NVAF that receive a blood thinner, it is common that the kidneys' ability to work properly, also called the kidney function, decreases. This may increase the risk of stroke, a condition which occurs when a vessel supplying blood to the brain is blocked and the risk of bleeding. It is therefore important to maintain the kidneys' ability to work properly in these patients who are treated with blood thinners. In the beginning, only one blood thinner that could be given as a tablet by mouth was available. This blood thinner was called warfarin. Over the years, further medications have become available, for example dabigatran or rivaroxaban. There is some evidence that a decrease of the kidney function is more common with warfarin than with dabigatran or rivaroxaban. For other similar new treatments however, evidence is missing or conflicting. There also could be other relevant factors such as the kidney function before the start of treatment or the patient's genes/origin. In this study researchers want to collect more data to compare two different blood thinner medications, rivaroxaban and warfarin. The main goal is to see whether there is a difference between the two treatments regarding the kidneys' ability to work properly. To find this out, the researchers will compare the number of patients in each group who developed chronic kidney disease stage 5 (close to or corresponding to chronic kidney failure), had a kidney transplant or needed to undergo long term dialysis. In addition, data is collected and compared about the patients' age, gender, weight, height and whether they had other related medical problems. This study will collect information from the health records from the Korean National Health Insurance Corporation (NHIC) database. Besides this data collection, no further tests or examinations are planned in this study. Researchers will look at the health information from adult men and women in Korea who were diagnosed with NVAF between January 2013 and December 2017. They will study data of the patients who did not receive any medication with blood thinners in past 24 months before starting rivaroxaban and warfarin treatment between January 2015 and December 2017. They will follow up all the participants until December 2018.
NCT02954237
The purpose of this study is to observe the safety and effectiveness of the AMPLATZER™ Cardiac Plug (ACP) device in Chinese population indicated for use of AMPLATZER™ Cardiac Plug after its market approval by China FDA (CFDA). This is a prospective, multi-centre, single arm, post approval, observational study. The clinical study will be conducted at up to 35 sites in China. Approximately 343 subjects will be enrolled in this study. The total study duration is expected to be approximately 7 years. The study population included patients who have non-valvular atrial fibrillation (NVAF) and are contraindicated to long-term oral anticoagulant; or patients who experience stroke or other thromboembolic event despite taking warfarin. Scheduled office visits occur at 45 days (+45 days), 6M (+/- 3 weeks) 12M (+/- 6 weeks) and 24 M(+/- 6 weeks) post procedure; Phone contact follow up visits occur at, 36 M (+/- 6 weeks), 48M (+/- 6 weeks) and 60 M (+/- 6 weeks) post procedures.
NCT01598051
The objective of this study is to understand if Rivaroxaban can improve treatment satisfaction of Warfarin patients and assess the safety and effectiveness of Xarelto in real clinical practice. A total of 725 patients are to be enrolled and followed for a 6 months.period. QOL survey will be conducted at month 0, 3, 6 using ACTS/TSQM. This study is categorized as a regulatory post-marketing surveillance in Japan, and it is a local prospective and observational study of patients who have received Xarelto for SPAF.
