Filter by:The goal of this pilot clinical trial is to evaluate the utility of a new electronic patient decision aid for stroke prevention therapy in patients with atrial fibrillation. The main questions it aims to answer are: Is the patient decision aid acceptable to both patients and physicians? Does the patient decision aid lead to more effective shared decision-making than standard care among patients with atrial fibrillation who are considering stroke prevention therapy? Participants with a recent diagnosis of atrial fibrillation will be enrolled before an upcoming specialist physician visit. Researchers will compare a pre-visit intervention consisting of standard educational materials plus use of the patient decision aid to educational materials alone to see if using the decision aid results in improved shared decision making during the clinic visit.
Atrial fibrillation (AF) is the most common cardiac arrhythmia in the world, with a large consumption of health resources. Telemedicine represents a new model of care, facilitating the individual approach to each patient and reducing costs and complications. This is an an open-label, randomized, multicenter, clinical trial aiming to analyze the use of telemedicine with AF patients in real clinical practice at primary care in terms of efficacy, efficiency, patient perception and professional satisfaction. The intervention will be based on the use of the Ti.Care app as the telemedicine support, in addition to the usual care. The follow-up will be carried out for 12 months.
Persistent atrial fibrillation (PerAF) can induce right atrial (RA) enlargement. Our previous study demonstrated patients with PerAF and RA enlargment may benefit from adjunctive RA ablation. Therefore, we conduct this multicenter, prospective, randomized study to confirm the value of adjunctive RA ablation.
The aim of this multicenter, pragmatic, open-label, randomized, placebo-controlled clinical trial is to test whether repurposing metformin for the treatment of atrial fibrillation will be effective in decreasing patients' hospitalization, adverse major cardiovascular events, and non-cancer death. Participants will be randomized into 2 study arms (385 participant each), whereby: - The Metformin Group (MG): will receive metformin oral tablets in addition to the standard rate/rhythm control strategy and anticoagulation. - The Placebo Control Group (PCG): will receive placebo oral tablets as a control group in addition to the standard rate/rhythm control strategy and anticoagulation. Then both arms will be compared according to the these endpoints: - The primary endpoint is hospitalization due to an episodic AF or an AF with a rapid or slow ventricular response (in the case of permanent AF). - The secondary endpoint is a composite of non-fatal major cardiovascular adverse events or non-cancer death. The non-fatal major cardiovascular adverse events include: - Hospitalization due to heart failure. - Non-fatal myocardial infarction. - Non-fatal stroke. - Hospitalization due to unstable angina.
The objective of the CAMERA-Pilot trial is to generate a hypothesis for a proper randomized controlled clinical endpoint trial to show the noninferiority of restoration and maintenance of sinus rhythm (via catheter ablation [CA] of AF) vs. mitral transcatheter edge-to-edge repair (M-TEER) in patients with AF and concomitant FMR. Patients will be stratified into ventricular FMR with atrial component and atrial FMR.
Hypertension and atrial fibrillation (AF) are two major public health problems worldwide. Hypertension is an important risk factor for AF, and the combination of which could significantly increase the risk of cardiovascular adverse events, and result greater disability rate and mortality. Hypertension can stimulate cardiomyocytes apoptosis, drive renin-angiotensin-aldosterone system (RAAS) activation, lead to left ventricular hypertrophy (LVH) and finally result in the structure remodeling of the atrium, which can trigger AF development through influence on myocardial electrical activity. Previous studies have found that angiotensin receptor blockers (ARB) seem to be more efficient in preventing AF when hypertension combined heart failure or LVH, but not completely clear in others with hypertension. Azilsartan is a new ARB, it replaces the tetrazole ring of the traditional ARB with the oxadiazole ring, which making it binds to the angiotensin type 1 (AT1) receptor more tightly, dissociate more slowly, and has a stronger antihypertensive effect. It was reported that Azilsartan could inhibit cell proliferation, reduce inflammation and oxidative stress. However, whether Azilsartan can reduce the risk of AF in hypertensive patients, and the possible corresponding mechanism is still unclear. Accordingly, the investigators designed this study intending to evaluate the effect of Azilsartan on the incidence of AF in hypertensive patients combined with LVH, and to explore the possible mechanism. This study is a practical, multicenter randomized controlled research method, the investigators will include 400 patients with hypertension and LVH who meet the inclusion criteria in Beijing Tsinghua Changgung Hospital and other centers. The patients would be divided into the Azilsartan group and conventional treatment group randomly, and be followed up regularly for 12 months. The incidence of AF in the two groups would be compared through the flexible intelligent ECG monitoring system, and the optimal blood pressure control, also the left ventricular hypertrophy and left atrial function would be evaluated. This study will provide evidence for the use of Azilsartan in blood pressure control and lower risk for AF patients with hypertension and LVH. It will be benefit for improving prognosis of patients with hypertension combined LVH, reducing the incidence of AF, and achieving good social economic effects.
The START-POAF pilot study is a prospective, open-label two-arm, randomized controlled trial with blinded assessment of outcomes (PROBE). This pilot study will assess Atrial Fibrillation (AF) recurrence and burden in patients with new-onset AF following cardiac surgery.
Atrial fibrillation (AFib) is a common type of cardiac arrhythmia in clinical practice, affecting millions of people worldwide. Early detection and treatment of atrial fibrillation are crucial in preventing serious complications such as stroke and heart failure. In recent years, with the flourishing development of wearable devices and mobile technology, electrocardiogram (ECG) measurement applications embedded in smartwatches have gradually become a non-invasive and convenient method for heart rate monitoring. However, the accuracy of these devices has not yet been fully determined. This study aims to verify the ECG measurement and atrial fibrillation detection function of the ASUS Blood Pressure Monitor/Oximeter/ECG Monitor. The accuracy of the ECG application in detecting atrial fibrillation and measuring ECG will be evaluated by comparison with standard 12-lead ECGs.
The purpose of this study is to understand temporal changes in clinical features and functions, and the relationship with outcomes of atrial fibrillation (AF). AF is a problem with speed or pattern that the heart beats. It is the most common type of arrythmia. The study will use data linkage of a single center patient data and national claims database in Korea. This study does not include an actual patient enrollment process.
Atrial Fibrillation (AF) is an abnormal rhythm of the heart which is increasingly common and can be associated with serious consequences. We know that AF is associated with an increase in the scarring of the heart, the left atrium and it is thought that this scarring may be one of the drivers for this abnormal heart rhythm. The nature of this scarring in humans has been subject to limited study and generally only by indirect means such as cardiac MRI scans or measuring the voltage of the tissues. During cardiothoracic surgery, tissue from the left atrium is removed as a part of the procedure. This tissue is normally disposed of, but we would propose to consent patients to collect it to allow it to be analysed. Such analysis would examine the composition of the tissue, including the pattern of scarring, to allow us to gain a greater insight into the mechanisms of AF.
