Filter by:Atrial fibrillation (AF) is the most common cardiac arrhythmia. Although the condition itself is not life-threatening, the complications result in increased morbidity and mortality. AF is often asymptomatic and a considerable number of people suffering from AF are not aware of their condition. Unfortunately, a cerebral infarction is often the first clinical manifestation. The idea to screen subjects opportunistically for Asymptomatic Atrial Fibrillation (AAF) was infeasible until recently. However, with a recently-developed smartphone connected Mobile ECG Device (MED), this seems to be feasible after all. The main objectives are: - To examine the feasibility of screening subjects of ≥65 years old for AAF. - To validate the smartphone connected MED as an AAF screening instrument for application in transmural care in the Netherlands.
Although epigenetics has been identified as one of the most relevant pathophysiological components in the development of cardiovascular diseases, there is still considerable difficulty in finding markers of epigenetic damage useful in clinical practice. Moreover, these markers could be useful to predict the onset and severity of disease as well as to stratify stratification the prognostic risk during the follow-up. The aim of this project will be to evaluate the genome wide DNA methylation status in circulating CD4+ T cells and CD8+ T cells in patients with acute coronary syndromes (ACS), atrial fibrillation (AF) and with ACS in the presence of AF.
In this study researchers want to learn more about on the safety of the drug Xarelto. The study will enroll patients for whom the treating doctor are prescribing Xarelto for the prevention of brain attack or the prevention of blockage of an artery in the non-central nervous system. Only patients suffering from decreased renal function and irregular heart beat will be considered. The study plans to include 500 Taiwanese adult male and female patients with the age above 20 years. Patients will be followed up based on routine medical practice over a period of 12 months and information on their well-being and any medical events will collected.
Prospective non-randomized parallel-assignment multi-center clinical investigation. The study design includes two subject cohorts: 1) Paroxysmal Atrial Fibrillation Main Study, and 2) Paroxysmal Atrial Fibrillation High Standard Power Substudy. Subjects in the main study cohorts are to be treated using the full range of ablation power settings in the Instructions For Use. Subjects in the High Standard Power Substudy are to be treated in the upper end of the recommended ablation power settings (40-50 Watts).
study to evaluate the performance of the CardiacSense1's embedded PPG under different environmental and physical conditions
The proposed clinical study aims to validate the diagnostic performance, compared to a reference ECG, of the ECG-SW1 software and the PPG-SW1 software integrated into the HWA09 watch developed by Withings for the automatic identification of atrial fibrillation (AF).
Background and Importance: When patients transition from hospital to home following surgery, perceived complications or poorly controlled pain can result in emergency department visits and readmissions. Continuity of care after discharge has been shown to reduce ED visits and readmissions rates. Hence any improved method of extending the continuity of care in a patient's home may improve postoperative outcomes. For patients who are at risk, continuity of care with digital solutions offers a pathway to providing more education, influencing behaviour, and creating better outcomes. Care teams can understand what's going on with each patient daily or weekly, as opposed to sporadically through an office visit. Goals/Research Aims: Atrial fibrillation is one of the important complications after thoracic surgery, it is estimated to occur in 10.5% of patients. We will conduct a randomized controlled trial to test the use of a secured digital system to monitor vital signs and home-based ECG monitoring for 2 weeks after surgery in patients undergoing an elective thoracic surgical procedure at the London Health Sciences Centre [LHSC]. Specific objectives are to determine the feasibility of 30-day emergency department visits as the primary outcome, 30-day readmission rates, postoperative complications, in-hospital length of stay, pain scores, hospital case costing, societal costs, mortality, and patient satisfaction. Methods/Approaches/Expertise: This trial will be a single centre, assessor-blinded, parallel arm, randomized controlled trial. Participants will be recruited from patients scheduled for thoracic surgical procedures at LHSC. Patients will be randomized to either the Continuity of care with Digital Home Monitoring (CDHM) group or the control group. The control group will be provided with the usual post-operative care, and the CDHM group will be provided with access to self-help resources, digital monitoring and access to a clinical navigator for two weeks. All outcomes will be compared between the CDHM group and control group at the end of 4 weeks post-discharge, including out-of-pocket costs, travel costs and lost productivity. Expected Outcomes: The Ontario Hospital Association estimates the average cost of a one-day stay in an acute care hospital is $1,300. With digital monitoring and continuity of care, we expect to decrease visits and readmission rates by at least 50% and in-hospital length stay by at least one day. This is a feasibility study. We will follow the traffic light approach criteria for reporting feasibility outcomes: Feasible (green) 75-100%: all feasibility outcomes are met; no protocol modifications are needed; (2) Feasible with modification (amber) 50-75%: all feasibility outcomes are met or can be met with protocol modifications; (3) Not feasible (red) <50%: even with protocol modifications, some feasibility outcome cannot be met.
To determine the diagnostic yield of a 30-day smartphone electrocardiogram recording compared to 24-hour Holter monitor for detecting occult paroxysmal atrial fibrillation in patients with a recent ischemic stroke or transient ischemic attack of undetermined etiology after completion of a standard clinical stroke work-up.
The first Russian registry presents data from two hundred consecutive patients with nonvalvular atrial fibrillation, who undergone left atrial appendage occlusion (LAAO) using the Watchman device and the Amplatzer cardiac plug. This government-funded catheter-based LAAO program was started in September 2015 and was completed in December 2017. Data collection was finished in December 2018. Five clinics agreed to participate in the study. Patients' baseline characteristics, procedure, and follow up data were collected according to established registry protocol. Patients were followed at 45 days, 3, 6 and 12 months after enrollment. At each follow-up visit, the data regarding clinical events and healthcare utilization was collected.
Atrial fibrillation (AF) displays high prevalence in heart failure with preserved ejection fraction (HF-PEF) and compromises prognosis of affected patients. This study aims to assess catheter ablation (CA) for AF in patients with HF-PEF compared to AF-patients without systolic or diastolic dysfunction. Primary endpoints are freedom from AF and quality of life at 1 year. Furthermore, the study is designed to elucidate mechanistic characteristics distinguishing arrhythmic substrate and predicting AF-recurrence in patients with HF-PEF. For this purpose, left atrial concentrations of biomarkers for inflammation, fibrosis and neurohumoral activation are determined and hemodynamic measurements are performed periprocedurally. Information on benefit from CA in these patients is necessary for clinical decision making and mechanistic investigations may point to tailored approaches in order to increase therapeutic efficiency.
