Filter by:Study name: Sacubitril Valsartan in Preventing the Recurrence of Atrial Fibrillation After Ablation in Elderly Hypertensive Patients With Atrial Fibrillation. Medicine: sacubitril/valsartan (100mg) and valsartan (80mg). Rationale: The latest guidelines represent an intensified management approach to reduce or prevent morbidity associated with atrial fibrillation. They provide stronger and more specific recommendations for catheter ablation (CA) use. However, not all patients maintain sinus rhythm after CA and both early and late relapses of AF can occur in many patients. Objective: To evaluate the efficacy and safety of sacubitril/valsartan in preventing atrial fibrillation recurrences after ablation in elderly hypertensive patients with atrial fibrillation. Study design: This is a 12-month prospective, randomized, active-controlled, open-label, multi-center study, with two treatment groups: sacubitril/valsartan (100mg tablet) and valsartan (80mg tablet). Study population: Men or women aged between 65 and 79 years will be screened for hypertension. Eligible patients should be untreated and treated atrial fibrillation patients with clinic systolic/diastolic blood pressure ≥130/80 mmHg, who are going to receive catheter ablation procedure. Patients should have abilities to understand the study requirements and provide informed consent. Randomization and treatment: After screening period by centers, eligible patients will be randomly divided into 2 groups, taking one pill of sacubitril/valsartan (100mg tablet) or valsartan (80mg tablet). Follow-up: After meeting the inclusion criteria, there will be 1-week screening period. Clinic blood pressure, ambulatory blood pressure, echocardiography, concomitant medication records and adverse event records will be collected at randomization period. Then patients will be randomly assigned into sacubitril/valsartan group and valsartan group. The treatment will be observed for 12 months. There will be 4 visiting points in the treatment period, which will be the 1st month, 3rd month, 6th month and 12th month. Sample size: A total of 300 patients should be enrolled in total. Timeline: After obtaining the approval of Ethics Committee of Ruijin Hospital, recruitment will start. Patients enrollment and follow-up are expected to be performed from October 2022 to December 2024.
The Micra MC1VR01 or Micra AVMC1AVR1 Transcatheter Pacing System (Medtronic, Inc., Minneapolis, MN, USA) has become a major breakthrough as an alternative to standard transvenous pacemakers. The aim of this multi-center study is to assess the clinical outcomes of patients implanted with Micra LLPM in real life, in different clinical scenarios.
A prospective cohort study to evaluate the association between various triggers encountered in daily life and induction of atrial arrhythmias (atrial fibrillation, atrial flutter, atrial tachycardia and premature atrial contractions) with the use of long-term monitoring devices. The collected data of personalized triggers and risk factors will be used to define the individual phenotype of atrial arrhythmia.
This study is a case-control study. In this study, 2ml of vein blood samples were collected from patients with atrial fibrillation undergoing radiofrequency ablation and those in the control group who underwent electrophysiological examination alone and confirmed no arrhythmia. The purpose of this study is to identify the relationship between the aldehyde dehydrogenase 2 (ALDH2) gene polymorphism and susceptibility to atrial fibrillation, and to explore the relationship between the genotype of ALDH2 SNP and the prognosis of patients with atrial fibrillation undergoing radiofrequency ablation.
The "Long-term Outcome and Predictors for Recurrence after Medical and Interventional Treatment of Arrhythmias at the University Heart Center Hamburg" (TRUST) study is an investor-initiated, single-center, prospective clinical cohort study including patients treated with cardiac arrhythmias or at high risk for cardiac arrhythmias. The design enables prospective, low-threshold, near complete inclusion of patients with arrhythmias treated at the UHZ. Collection of routine follow-up data, detailed procedural information and systematic biobanking will enable precise and robust phenotyping.
The PROGRESSIVE-AF Trial is a national, multi-center randomized controlled trial comparing early ("first-line") catheter-based pulmonary vein isolation (PVI) using cryothermal energy to first-line anti-arrhythmic drug therapy. The aim of the trial is to evaluate if the initial treatment choice (ablation vs. pharmacotherapy) influences AF disease progression, as measured by continuous cardiac monitoring. The outcomes of interest are disease progression, quality of life, and healthcare utilisation. The targeted population consists of healthy patients with symptomatic paroxysmal AF without clinically significant heart diseases aged between 18 and 75 years. This study represents a new research project leveraging the existing EARLY-AF randomised clinical trial infrastructure to examine the novel endpoints of: 1) disease progression ("time to first episode of persistent AF"), 2) progressive AF burden ("% time in AF"), 3) Quality of Life, and 4) healthcare utilisation at 36 months of follow-up.
Background: Despite improvements in surgical and anesthesia procedures over the past 15 years complications during cardiac surgery still remain high. Bridgewater B et al. describes mortality during on-pump coronary artery bypass grafting (CABG) at 2%-3%, and the rate postoperative complications about 20%-30%. At the same time, the standard of care in patients undergoingon-pump CABG is not fully established. Hypothesis, Research Need: Use of multimodal low-dose opioid anesthesia during CABG decreases inflammatory response and the incidence of early postoperative cardiac complications due to a reduction in interleukin-6. Methodology: According to anesthesia standard protocol, all patients were divided into two groups - study group with multimodal low-dose opioid anesthesia (60 patients) and control group with a high-dose opioid anesthesia (60 patients). Primary (IL-6 at the end of the operation) and secondary clinical outcomes (postoperative atrial fibrillation (POAF), low cardiac output syndrome (LCOS), duration of mechanical ventilation (MV), length of intensive care unit (ICU) stay, length of hospital stay) were compared between the groups. Analysis Tools: Clinical observations; instrumental research methods (electrocapdiography, echocardiography); labs (blood gases, hemoglobin, electrolytes); enzyme-linked immunosorbent assay (IL-6); statistical (Student's t-test, Mann-Whitney U test, χ2-test, correlation analysis). Expected Outcomes: Use of multimodal low-dose opioid anesthesia during CABG will decrease inflammatory response (lower levels of IL-6 at the end of the surgery) and the incidence of early postoperative cardiac complications, expressed as lower incidence of LCOS and POAF, lower duration of MV and lower length of ICU stay.
The purpose of this study to assess the diaphragm kinetics with Tissue Doppler Imaging in patients undergoing atrial fibrillation ablation with cryoballoon
Influence of patient-reported outcome follow-up based on the northern Shanghai community chronic disease management system on the follow-up compliance and satisfaction of patients with atrial fibrillation after cryoablation.
