Filter by:The aim of this study is to evaluate if internet- delivered cognitive behavior therapy (CBT), based on exposure principles and behavioral activation, improves QoL and symptom burden in patients with symptomatic atrial fibrillation (AF), controlling for expectancy of improvement and attention from a caregiver, using an active control group (stress management). The study will include 260 patients with symptomatic AF despite optimal medical treatment in accordance with current guidelines.
This is an observational, multicentre, prospective, post-market product registry for participants with AF for whom ablation by the commercially available Globe Mapping and Ablation System was indicated before enrolment into the registry. The aim of the registry is to confirm the clinical performance and safety of the Globe Mapping and Ablation System in a real-life setting.
Atrial fibrillation (AF) is a prevalent and serious disease in hemodialysis (HD) patients. Untreated AF increases the risk of deaths related to cardiovascular events and multiplies the risk of strokes by 5. Anticoagulation with warfarin significantly reduces the incidence of ischemic strokes in the general population, has a long half-life, and a narrow therapeutic index that requires periodic monitoring. In addition, warfarin treatment is a frequent cause of hospital admission for iatrogenesis. In HD patients, the relationship between stroke prevention benefit and bleeding risk is an unmet medical need. It should be noted that in these patients the risk of bleeding is multiplied by 3 to 10 times compared to the general population. The new direct-acting oral anticoagulants (NACOs), thrombin inhibitors (dabigatran), and activated factor X inhibitors (rivaroxaban, apixaban, edoxaban), do not require regular monitoring, but their plasma concentrations are altered with the deterioration of the renal function. According to its technical data sheets, they do not recommend its use in clinical practice for HD patients. However, the apixaban data sheet includes the results of a pilot clinical trial in the African American population on HD, suggesting that it is a safe anticoagulant drug. The objective of this clinical trial is to evaluate the pharmacokinetics, pharmacodynamics, and short-term safety (4 weeks) of apixaban in the Spanish population with non-valvular atrial fibrillation and on hemodialysis. Long-term safety will be assessed in the extension study: prospective cohort study of patients included in the clinical trial. Therefore, this project is comprised of 2 clinical studies (one clinical trial and one extension study) whose objective is to evaluate the pharmacokinetics, pharmacodynamics, and short and long-term safety of apixaban in patients on hemodialysis and with non-valvular atrial fibrillation (FANV). The results of this project (clinical trial and extension study) will provide evidence on whether apixaban may be the anticoagulant treatment of choice for this type of patient.
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.
EQUAL-AF is an observational feasibility study which will determine if there is a long-term effect of bleeding for patients diagnosed with AF, who are taking anticoagulants. The investigators will use three validated questionnaires/PROMs (AFEQT, EQ5D-3L, and PACT-Q) to gather data from a patient perspective. Patients will complete all questionnaires no more than 4 weeks following a bleed and a second time 3 months later. As this study tests feasibility, progression criteria will apply. The primary objective is to assess recruitment success to ensure that the patient population is accessible and willing to engage with the research team. Additionally, the investigators will look to identify the need for a specific bleeding PROM which will assess long-term quality of life impact for patients experiencing bleeds while anticoagulated.
Sympathetic tone is important in cardiac arrhythmogenesis. The simultaneous recording of sympathetic nerve activity (SNA) and electrocardiogram (ECG) was obtained by invasive method. The purpose of this protocol is to further develop this recording method to turn it into a new non-invasive tool for arrhythmia prediction and detection. This method may also be useful in validating the results of surgical procedures aimed at sympathetic denervation
There has not been a prospective, randomized controlled trial of colchicine to reduce post-AF ablation pericarditis in an era of newer AF ablation techniques. The hypothesis is that an empiric pre and post AF ablation treatment protocol with colchicine may reduce the incidence and symptom severity of post-AF ablation related pericarditis. Thus, the goal of this study is to 1. Identify the incidence of post-AF ablation related pericarditis in patients undergoing ablation via high power, short duration strategy (shorter total RF time, but increased stability due to steerable catheters and possible difference from resistive vs conductive heating). 2. Identify potential differences in patients undergoing PVI only versus PVI + additional ablation 3. Identify whether patients on who are already on anti-inflammatories such as ASA or statins have a lower incidence than those without 4. Determine if an empiric treatment strategy with colchicine (for 7 days post ablation) reduces the incidence of post-operative AF
This research will investigate the PPG signal morphology related to physiological and non- physiological changes in arrhythmia-related heart rate as well as the performance of the PPG-based features previously developed within the framework of the Mini-Holter study to discriminate between several cardiac arrhythmias. To this end, clinical data will be recorded on patients by using a wrist-based PPG monitor simultaneously with 12-lead ECG and intracardiac electrogram (EGM) signals at the university hospital in Lausanne. Importantly, this study will remain purely observational as it will not change the diagnostic and therapeutic management of the included patients, nor will it interfere with the time course of the procedures. The aim of enHEART study is to validate on a larger database the ability of several previously developed PPG-based features to detect a variety of cardiac arrhythmias.
Atrial fibrillation is the most common cardiac arrhythmia, the incidence of which increases drastically with age. As more and more elderly patients undergo heart surgery, the proportion of patients in this population will increase. Atrial fibrillation has been shown to be a poor prognostic factor in several surgical situations. The aim of our study was to assess long-term mortality among patients with preoperative AF under various cardiac surgery settings, with a particular emphasis on the strategy of coronary revascularization.
AV-node ablation (AVNA) is a common therapy option for rate control strategy of permanent atrial fibrillation with numerous side effects. The investigators hypothesised that an isolation of the AV node is concomitant with less occurrence of new bundle brunch blocks, more frequent preservation and higher rate of escape rhythm compared to AVNA. This retrospective study includes 20 patients being treated with AV-node isolation (AVNI) and 40 historical AVNA-controls. Among others these two methods were compared regarding escape rhythm, delta QRS, procedure time, ablation points, fluoroscopy time and total dose area product (DAP).
