Filter by:Vasco trial is a no profit, multicenter, international, prospective, randomized study designed to evaluate the clinical benefits of a remote monitoring management based on ILR vs standard practice in patients with high risk of cardiac arrhythmias, heart failure and left ventricle ejection fraction (LVEF)> 40% .The study will enroll about 331 patients (221 in the ILR group and 110 in the in-hospital follow-up group).
This study aims to design and train a deep learning model for the diagnosis of different arrhythmias.
The investigation of biomarkers for immune status and metabolic state, as well as host microbiota composition, in patients with ventricular arrhythmias before and after radiofrequency ablation, can provide new insights for specific and personalized treatment. This can help establish early prediction and prognosis models and provide a basis for clinically effective diagnosis and treatment.
Prospective, observational, single center, pilot study to analyze the feasibility of motion and structural data integration in patients with ventricular arrhythmia by means of artificial intelligence for improved arrhythmogenic substrate characterization and motion management during stereotactic arrhythmia radioablation.
This study seeks to provide evidence that use of Philips mobile cardiac outpatient telemetry (MCOT) devices may improve patient care for patients who present to emergency departments (EDs) with syncope, which is a temporary loss of consciousness also known as fainting or who present experiencing a near temporary loss of consciousness (near syncope). It is set up as a random controlled trial, which means research participants will be randomly assigned to receiving the device or usual care. Patients 50 years or older who come to the ED of Carilion Roanoke Memorial Hospital will be screened by study team members for unexplained syncope or near syncope across three ED dispositions: hospital admission, emergency department clinical decision unit admission (ED CDU) and emergency department. After consent, subjects will be enrolled and randomized, via REDCap randomization, in the study. At the time of subject discharge the MCOT device will be placed on the chest for the arm of intervention patients (for subjects who were admitted, the research study team will follow the patient's clinical course and placement of the device will occur at discharge); subjects will also receive brief instruction on the care and maintenance of the device and a patient education guide. The research team will contact the subjects for a telephone follow up at 14 and 30 days post-enrollment. The study will establish the efficacy of mobile cardiac outpatient telemetry in comparison to observation telemetry. Research objectives are to 1) Measure the time to medical intervention in patients with unexplained syncope or near syncope fitted with a Philips MCOT at the time of hospital discharge compared to patients treated with usual care for unexplained syncope or near syncope; and 2) Measure the time to arrhythmia diagnosis in patients with unexplained syncope or near syncope fitted with a Philips MCOT at the time of hospital discharge compared to patients treated with usual care for unexplained syncope or near syncope.
The investigators will examine the effects of dynamic light therapy on circadian rhythms in intensive care unit (ICU) patients. In a randomized controlled trial (RCT), they will investigate the effects of a specific light algorithm on rhythms of serum melatonin, clock gene expression, the proteome, and metabolome, compared to standard hospital lighting, supported by the data science algorithms to improve vital-based algorithms with light interventions.
This study aims to evaluate the incidence, clinical characteristics, and short-term prognosis of acute cerebrovascular events occurring in-hospital in patients with arrhythmias following catheter ablation. The goal is to provide evidence supporting the improvement of patient quality of life and reduction of in-hospital acute cerebrovascular complications in patients with post-ablation arrhythmias. This will also contribute to the evidence-based clinical management of such patients.
This clinical study will be conducted with funding from European Innovation Council(EIC) after approval of the fund grant and is part of our organization's European Pathfinder Project(Ref: HORIZON-EIC-2022-PATHFINDERCHALLENGES-01). The clinical study step of this project will be started in a retrospective time prospective manner by gathering the phenotypic(clinical measuring factors) data from patients who underwent ICD implantation therapy. The study will be done as a case-control type in which patients who did not get any shocks in 6 months post-implantation will be allocated to the control group. A customized and highly specific cardiogenomics panel will be designed and ordered to be specially manufactured as a standard kit by Illumina® (San Diego, California, U.S.) following an exhaustive investigation for collecting genetic variants which correlated to cardiovascular development. Mentioned kit bears the standard and validated technology which is part of the genetic tests routine and is being produced by Illumina® incorporate. However, as an option manufacturer is designing custom kits for research purposes by getting the desired variant lists using the same technology. Accordingly, enrolled patients in the study will be prospectively sampled ( Non-Invasive saliva sampling) for getting genetically analysed by Illumina®'s Infinium Assay Microarray platform with fully customized 700,000 single nucleotide polymorphism kits. The result of this sampling will be data and statistically analysed in a genome-wide association study(GWAS) manner by considering the 5x10-8 p.value and will be associated with each phenotypic parameter. Accordingly, the study will assess the genetic risk stratification in ICD patients in a much more detailed fashion. Following this assessment genophenotypic statistical analysed will be done to combine both parameters and generate a formula for scoring the indicator factors based on each odds ratio. Correspondingly, this new scaling formula will be analysed, verified and validated further by a randomized sampling of the population in our study before being stated. Additionally, This study will not only help to improve current genetic polymorphism clinal significant status (pathogenicity and significance of variant) but also can associate new markers with high significance that can be directly used in clinical screening, diagnosis or clinical approaches.
Patients with various cardiac conditions (such as those who experience a heart attack) are increasing in Canada and are in need of appropriate cardiac rehabilitation and care. Many patients do not have access to local in-person cardiac clinics, particularly in rural regions of Canada. A user-friendly digital application with accessible educational resources and recommendations based on the most up to date clinical practice guidelines can help mitigate these issues. VIRTUES is a digital healthcare application that targets 11 modifiable modules as follows: 1. antithrombotic management 2. lipid management 3. rate and rhythm control for atrial fibrillation 4. heart failure care 5. post myocardial infarction care 6. blood sugar management 7. blood pressure management 8. physical activity 9. healthy eating 10. smoking cessation 11. alcohol reduction Of the 11 total modules, the first 7 listed provide recommendations in VIRTUES. The remaining 4 (physical activity, healthy eating, smoking cessation and alcohol reduction) consist of simple referrals to existing recommendations (i.e., for healthy eating and physical exercise) and referrals to existing local programs (i.e., for smoking cessation and alcohol reduction). Thus, in this cohort study, the investigators will test the primary 7 modules with 200 patients per module for approximately one month each in order to obtain feedback on the usability of each module. The investigators will also conduct virtual focus group discussions to obtain open ended feedback on the application. This study will provide valuable feedback, which will be used to improve and adapt the VIRTUES application.
Prior multicenter study demonstrated superiority of PURE EP to conventional mapping. This superiority was seen when comparing small, fractionated signals of interest, near-field vs far-field distinction, and general signal quality (2). Hence, investigators propose a retrospective study to assess the predictive value of high frequency algorithm (HFA) for identifying local physiologic signal under 0.3 mV distinctive of noise.
