Filter by:To assess the acute efficacy of ablation of the most stable VX1 areas (levels 2 and 3) in terms of the rate of acute AF termination. Identify the spatial distribution of dispersion stability levels based on VX1. Document the rate of adverse events. To assess the long-term efficacy of ablation of the most stable VX1 areas in terms of the absence of documented arrhythmias during a 12-month follow-up.
Investigate the compliance of oral anticoagulants in Chinese NVAF patients and find out the causes, so as to provide basis for formulating effective measures to improve the compliance of oral anticoagulants.
This study is to assess the effectiveness and safety of using cryoballoon ablation comparing with anti-arrhythmic drug therapy as initial treatment for naive patients with persistent atrial fibrillation.
"Atrial fibrillation (AF) is an arrhythmic disease that increases especially in the elderly, increasing the risk of ischemic stroke by 5 times and is a major cause of dementia and cognitive impairment. Cognitive dysfunction accompanying AF occurs regardless of the presence or absence of stroke, and AF itself is known to affect cognitive function. However, since cognitive dysfunction is also affected by various accompanying chronic diseases, whether the cognitive dysfunction accompanying AF is due to subclinical ischemic stroke, cerebral hypoperfusion due to reduced cardiac output, inflammatory reaction or platelet dysfunction are unclear. Recently, this research team reported an improvement in cognitive function with active sinus rhythm therapy such as AF catheter ablation. Nevertheless, it has not yet been proven whether such active and invasive AF treatment affects the improvement of cognitive function or depression by a randomized clinical trial. In this prospective randomized clinical comparative study, the investigators will compare the AF catheter ablation group and drug therapy group in terms of cognitive function tests and depression psychological tests at baseline and a year after treatment. Our hypothesis is that AF catheter ablation is superior to drug therapy to improve cognitive function and depressive mood.
The AcQForce AF-EU clinical study is a prospective, multi-center, non-randomized global clinical study designed to demonstrate the safety and performance of the AcQBlate Force Sensing System.
Atrial fibrillation (AF) is the most common abnormal heart rhythm disturbance, affecting 1-2 million people in the UK. The irregular heartbeat caused by AF can make the heart pump blood less efficiently. As a result, AF significantly increases the risk of having a stroke, heart failure and dementia. However, a significantly proportion of people have no symptoms, and they may be only found to be in AF after having a stroke. Therefore, diagnosis largely relies on accurate electrocardiogram (ECG) monitoring. AF episodes can be unpredictable and easily missed unless continuous ECG monitoring is undertaken. Pacemakers can continuously record the heart's electrical activity and detect AF with a high degree of confidence. However, they are invasive and rely on electrical wires implanted inside the heart, and hence less suited to be used as primary monitoring devices. To overcome these difficulties, implantable cardiac monitors (ICM) have been designed to be placed under the skin. The new generation of ICMs can now be injected under the skin. Moreover, they connect with the patient's smartphone and transmit recordings. Despite these significant improvements, their ability to reliably capture AF has never been tested against pacemakers. The aim of this project is to study the performance of the two commonly used ICMs in detecting AF episodes and explore how the new connectivity can empower patients and improve patient care. The investigators plan to inject an ICM in 30 patients with AF and pre-existing pacemaker. After a period of 6 months, the investigators will compare how many episodes were detected in each device. With the information collected the investigators will try to understand the pitfalls in the current technology and develop strategies to improve it. Accurate, minimally invasive long-term ECG monitor can have far reaching benefits for patients, both in routine clinical practice and research.
Assess the subject acceptance of MPT, using therapy parameters that have been shown to be effective in terminating episodes of atrial fibrillation.
AF is the most common sustained arrhythmia in adults and its prevalence increases with advancing age. In this study, we aim to determine whether the published genome-wide polygenic scores for atrial fibrillation (GPSAF) can facilitate AF screening by accurately discriminating between patients with low and high risk for AF. All included patients are participating in the MHI biobank, an ongoing funded institutional DNA bank and clinical registry approved by the research ethics board where included patients consent for future genetic research. The study will compare AF detection rate using a 3 months near continuous monitoring in individuals with a high GPSAF with matched individuals from the bottom GPSAF.
Antithrombotic drugs, which include antiplatelet and anticoagulant therapies, are used to prevent and treat many cardiovascular disorders. With the increase in prevalence of cardiovascular diseases and medical progress, these treatments are increasingly being prescribed, particularly in older patients. One of the main indications of antithrombotic drugs is atrial fibrillation (AF), a disease highly prevalent in older people, a population at high risk of adverse drug events. Notably, antithrombotic drugs are the first involved in serious adverse drug events, among which 40-70% may be preventable. In this context, six units of the hospital group "Assistance Publique - Hôpitaux de Paris" have created a multidisciplinary team which assesses antithrombotic prescriptions in older patients with AF. This team, gathering geriatricians, cardiologists, neurologists and haematologist specialized in haemostasis, evaluates the patient medical profile and suggests the most appropriate antithrombotic treatment based on their expertise and the available recommendations. Here we want to look at patients outcomes in light of the intervention of this multidisciplinary team.
DEFINE AFib is a prospective, observational, post-market clinical study administered to patients via the Medtronic Discovery app platform. This study will enroll approximately 5,000 patients in the United States who have a Reveal LINQ or LINQ II ICM (or future market-released LINQ devices) and an Apple® iPhone® with iOS version 13 or higher. Interested participants will be screened through the Medtronic Discovery app and those eligible will complete an app-based informed consent. Participants will receive health-focused and quality of life surveys at variable timepoints. DEFINE AFib will measure healthcare interactions using administered surveys to identify said interactions. The Medtronic Discovery app will provide participants with a summary of their ICM data. Participants will be followed up to 5 years or to the end of their ICM service life.
