Filter by:Aims Approximately 20-25% of strokes are of cardioembolic origin, atrial fibrillation (AF) being a significant cause of cardioembolic strokes. AF is often symptomless and intermittent, making its detection a clinical challenge. Currently the golden standard for diagnosis of AF is by 12-lead electrocardiogram (ECG) or any other ECG-strip. The primary aim of the study is to assess the potential of chest strap as an ECG monitor especially in arrhythmia detection by cardiologist and algorithm. The secondary aim is to assess potential of photoplethysmography (PPG) based device for arrhythmia detection.
The MEDEA project is envisioned to provide the field-based evidence for the adoption of a strategic plan for mitigating the health effects of desert dust storm (DDS) events in South-Eastern Europe. Over the past decade, several studies have demonstrated that DDS in Mediterranean countries, originating mostly from the Sahara and Arabian Peninsula deserts, have been increasing in number and magnitude and linked it to desertification, climatic variability and global warming. EU legislation considers DDS impossible to prevent, implicitly harmless and discounts their contribution to daily and annual air quality standards of particulate matter up to 10 microns (PM10). However, there is increasing evidence from epidemiological studies, which correlates exposure to PM10 during DDS with a significant increase in mortality and hospital admissions from cardiovascular and respiratory causes. Therefore, there is a pressing need for EU policies to reduce population exposures and increase individual, population and institutional resilience to the growing frequency and intensity of DDS. MEDEA ultimate goal is to demonstrate the feasibility and effectiveness of an adaptation strategy to DDS and better inform EU policy making. The adaptation strategy will be carried out within two panel studies, with two different groups of patients; 1. Children with asthma and 2. Adults with atrial fibrillation (AF). The primary objective will be to quantify the vulnerability of children with asthma and adults with AF during DDS outbreaks and provide evidence-based estimates demonstrating which interventions/recommendations work best in mitigating adverse health effects in this group of patients after randomization of each group of patients to three parallel intervention groups: a) No intervention for DDS; b) Intervention for outdoor exposure reduction, and c) Interventions for both outdoor and indoor exposure reduction. The secondary objective of the study is to demonstrate which of the recommendations are effective in reducing outdoor and indoor exposures to DDS in a panel of children with asthma and in a panel of AF adults. Intervention: Each group of patients (children with asthma and AF patients) will be recruited and will be randomized during the high DDS outbreaks season (Spring 2019 and 2020) with 1:1:1 ratio into three parallel groups to receive: a) No intervention for DDS; b) Intervention for outdoor exposure reduction, by reducing the time spend outdoors and by avoiding physical activity and c) Interventions for outdoor (as above) and indoor exposure reduction (by minimizing home ventilation and filtering indoor air). Disease-related adverse health outcomes will be assessed in the three parallel arms of the study. Approaches for delivering the intervention: A bidirectional, patient-centered e-Platform will be developed in order to facilitate prompt communication with the participants and provide early warnings regarding forecasted upcoming DDS events through text messaging and smartphone applications. Furthermore, the same IT platform and mobile application will be utilised for the dissemination of the exposure reduction guidelines that the participants will follow. Assessment of adherence to intervention: 1.Monitor compliance to exposure-reduction guidelines using remote sensors. The intervention for outdoor exposure reduction, entailing reduction of the time spend outdoors and avoidance of physical activity, will be assessed with the use of smart wristwatches that will be equipped with Global Positioning System (GPS) and an accelerometer. 2.The intervention for indoor exposure reduction, entailing minimization of home ventilation and filtering of indoor air, will be assessed with the use of particle samplers that will be placed outside and inside of houses and school classrooms.
This study is designed to compare the performance of both 6 and 10 electrode ECGs from the handheld device with the conventional 12 lead ECG. As well as comparing the detection of atrial fibrillation, the study will also compare the detection of other heart problems and of normal heart rhythm.
This research study is being done to find out whether autoimmune mechanisms are associated with the development of atrial fibrillation.
The study evaluates the use of half-normal saline as an irrigant for open-irrigated catheters during atrial fibrillation ablation. By increasing the efficacy of radiofrequency energy-mediated lesion formation, half-normal saline has the potential to reduce procedural times and improved acute and long-term outcomes.
Study Design: Lixiana Acute Stroke Evaluation Registry (LASER) is a randomized controlled trial with an associated registry. Patients with previously known or newly diagnosed atrial fibrillation (AF) and acute ischemic stroke within five days will be randomized 2:1 to early (≤ 5 days) or delayed (6-14 days) edoxaban initiation. Ischemic stroke will be defined as evidence of acute focal cerebral infarction confirmed on CT/MRI and/or focal hypoperfusion/vessel occlusion on multimodal CT, or by sudden focal and objective neurological deficits (i.e NIHSS ≥ 1) of presumed ischemic origin persisting > 24 hours. Study Aim and Objectives: The primary aim of LASER is to demonstrate the safety of edoxaban initiation within five days of cardioembolic stroke. Secondary aim is to determine predictors of hemorrhagic transformation (HT) after cardioembolic stroke. Investigators will systematically assess prospectively collected Computed Tomography (CT) scan images for evidence of HT and re-infarction.
The purpose of the study is to confirm the software's ability to create a Lead-1 electrocardiogram (ECG) that is clinically equivalent to a reference device. Also, to confirm a rhythm classification algorithm and its ability to detect and classify heart rhythms into two categories (Sinus Rhythm or Atrial Fibrillation) using a single Lead ECG.
Isolated reports have indicated that complete Left Atrial or Left Atrial Appendage thrombus resolution may be achieved also with use of oral Factor Xa inhibitors, which have demonstrated the same efficacy but a better safety profile compared to warfarin. The aim of this open-label pilot study is to investigate the percentage of Left Atrial /Left Atrial Appendage thrombus resolution with edoxaban therapy in patients with non-valvular atrial fibrillation. The subordinated aim is the design a larger and longer study to compare edoxaban and warfarin in the same patient population. With the exception of few case reports, there are no data in the same patient population referred to antithrombotic treatments other than vitamin K antagonists.
This pilot study evaluates the addition of the EnsoETM esophageal cooling device to the radiofrequency (RF) ablation procedure in the treatment of atrial fibrillation in adults. Half of participants will receive the EnsoETM in addition to RF ablation, while the other half will receive luminal esophageal temperature (LET) monitoring during RF ablation.
To compare the efficiency and safety between gene-oriented group and standard care group during 90 days of initial warfarin-treatment for requiring anticoagulation patients with valve replacement or atrial fibrillation with or without valvular heart disease。
