Filter by:To validate the prognostic importance of the burden of new-onset atrial fibrillation (NOAF) complicating acute myocardial infarction (AMI) in a prospectively designed hospital-based registry. To characterize those factors that contribute to the progression of post-MI NOAF burden. To establish a prediction model for the risk stratification of patients with NOAF complicating AMI. To explore the clinical usefulness of NOAF burden in guiding the anticoagulation therapy among patients with post-MI NOAF.
This study is a prospective, single-arm, open-label study following patients to 1 year, to evaluate the safety and performance of the Centauri System for catheter ablation of atrial fibrillation (AF). The study is intended for adult patients (age 18-75 years) who are indicated for a first-time catheter ablation of AF where the pre-procedure treatment plan contemplates pulmonary vein isolation (PVI) in patients with paroxysmal AF (PAF) or short-duration (<1 year) persistent AF (PeAF).
This study aims to test the effectiveness of positive airway pressure therapy on reducing clinical failure after rhythm control treatment and restoring with regular heart beat in atrial fibrillation patients with obstructive sleep apnea.
Patients undergoing cardiac surgery are at high risk of developing atrial fibrillation (AF), with estimated rates of 30-50% and occurs at approximately 2-4 days after surgery. The autonomic nervous system is known to play a key role in AF. Animal studies have indicated that duration and inducibility of AF can be decreased with intermittent vagus nerve stimulation (VNS). In humans, literature suggests that transcutaneous (tragus) VNS (tVNS) can serve as a potentially non-invasive therapy for treatment of post-operative AF (POAF) by reducing inflammation and increasing atrial refractory period. The purpose of this study is to determine the value of tVNS in reducing the burden of POAF and days of hospitalization after cardiac surgery.
Obstructive sleep apnea is associated with atrial fibrillation. This study is to evaluate the effect of continuous positive airway pressure on the burden of atrial fibrillation in the patients with obstructive sleep apnea and paroxysmal atrial fibrillation.
Objective To investigate if conduction system pacing ((CSP) i.e. atrioventricular node ablation + His bundle pacing or Left Bundle Branch pacing) is as good as (or better than) atrial fibrillation ablation with pulmonary vein isolation for older patients (70-85yrs) with symptomatic atrial fibrillation and at least moderately dilated left atrium. Patient population: 90 patients aged 70-85 years with atrial fibrillation, referred to either AV node ablation or pulmonary vein isolation. Primary endpoint: Improvement in health-related quality of life as measured by the physical component summary (PCS) of the well-validated SF-36 form, at one year after AV node ablation + CSP or AF ablation. Secondary endpoints: Physical performance measured by 6-minute walk test, biochemical markers of heart failure (NT-ProBNP), frequency of complications, left ventricular systolic and diastolic function, and left atrial size evaluated after 12 months. Arrhythmia specific symptoms and anxiety will be measured with the ASTA and HADS questionnaires. Arrhythmia symptom correlation between subjective and objective findings. After three years, clinical endpoints will be evaluated regarding overall survival, and risk of heart failure hospitalization or death. The cost of the treatments will be compared, and estimated cost per quality adjusted year of life will be calculated, based on the EQ5D questionnaire.
The purpose of this registry is to depict the myocardial function improvement in AF patients by integrated therapy and to assess the prognostic discrepancies of various intervention modalities. Information will be collected prospectively in about 5000 AF patients. Subjects will be followed for up to 3 years.
The primary objective is to assess the safety and efficacy of switching from direct oral anticoagulants to low molecular weight heparin in cancer patients during antineoplastic therapy
Atrial fibrillation is the most common arrhythmia. The posterior surface of the left atrium is covered by an extensive network belonging to the autonomic nervous system that can be damaged during the ablation. The involvement of the autonomous nervous system in the genesis and maintenance of atrial fibrillation remains poorly understood. Baroreflex sensitivity is a non-invasive method assessing autonomous nervous system activity. The rate of atrial fibrillation recurrence after ablation is currently high and a better understanding of the mechanisms associated with recurrence is essential to improve selection of the patients who will benefit the most from this procedure. The aim of this study is to evaluate the association between the baroreflex sensitivity and atrial fibrillation recurrences and to analyze the prognostic contribution of the baroreflex measurement compared to other published criteria.
