Active clinical trials for "Atrial Fibrillation"

Atrial Fibrillation is considered as one of a common cardiac arrhythmia that presented with rapid and irregular rhythm and has an increased incidence.There are different types of atrial fibrillation one of these is paroxysmal atrial fibrillation that defined as lasts longer than 30 seconds and lasting less than 7 days, while atrial fibrillation lasting more than 7 days to less than one year or requiring pharmacological or electrical cardioversion is called persistent atrial fibrillation, referring to the American Heart Association 2006 guidelines.Patients with atrial fibrillation suffer from serious complications like stroke due to thromboembolism, heart failure and death. Risk of stroke is 5-folds in patients with atrial fibrillation in addition to presence or absence of another clinical risk factors.

This study aims to assess the feasibility and reliability of smart watch iECG provided by the Apple Watch/Apple iPhone for the detection of different cardiac arrhythmias. In this study, results from a 12-lead ECG will be set as the gold standard for the arrhythmia diagnosis, and results from the smart watch iECG (Apple watch/Apple iPhone application and Cardiologist's interpretations) as the index tests. The iECG tracings will be recorded simultaneously, starting and ending at the same time as the standard 12-lead ECG, using the built-in sensors of a smart watch (Apple Watch Series 4) with the ECG application.

Atrial fibrillation (AF) is reaching epidemic proportions in the aging U.S. and European populations, but the mechanisms of increased susceptibility to atrial fibrillation are still unknown. In this study, we look to further examine genetic and medical co-morbidity influence of atrial fibrillation duration and response to medications. In Specific Aim 1, we propose the creation of a Veterans Affairs AF Biorepository (VAAFBio), which is a resource that will collect and store clinical, demographic, blood and DNA samples from patients with atrial fibrillation to aide this study and future studies of this type in the VA population. In Specific Aim 2, examine common genetic polymorphisms in veteran patients with atrial fibrillation and examine gene-environment interactions with risk factors for atrial fibrillation.

Investigators developed a multidimensional protocol for the management of AF in the emergency department. Investigators aimed to assess if this new ER AF management protocol would result in better outcomes compared to routine care.

Atrial fibrillation (AF) is the most common cardiac arrhythmia. This study is to assess the heart rhythm device accuracy of five cardiac wearable devices (Apple Watch, Kardia Mobile/Kardia Mobile 6L, Fitbit Sense, Samsung Galaxy Watch 3 and Withings Scanwatch, Withings SA, Model Number: HWA09) and its detection algorithms in identifying AF compared to a nearly simultaneously acquired physician-interpreted 12-lead ECG in a real world cohort of patients.

The main outcome of this study will be to compare the prevalence of PA AF episodes longer than 30 seconds versus the prevalence of PA AF episodes including episodes shorter than 30 seconds, in adult patients who survived IS or TIA with no previous history of AF, after 7-day Holter monitoring. Based on the previous assumptions, the secondary objectives of the project will be: To compare the prevalence of patients diagnosed with BAF after 24-hour, 72-hour, and 7-day Holter monitoring. To study the feasibility of using information obtained from the ECG during sinus rhythm, for example the characteristics of the P-wave, to predict the presence of PA AF and BAF. To Collect a new database of multi-monitored, high-resolution, long-term ECG signals. The data will be used by the My-Atria consortium for research purposes, for the development and validation of arrhythmia detection algorithms. The results of the study are intended to have an impact on how AF is screened, diagnosed, and treated. The results will also contribute to the choice of the most appropriate secondary stroke prevention modality, which therefore refers to the treatment of subjects who have already had an episode of IS or TIA.

This is a prospective, multicenter, cohort study aims to demonstrate the role of termination of AF in ablation for persistent atrial fibrillation, and evaluate the clinical outcomes in patients with or without AF termination.

The atrial fibrillation (AF) is the most common cardiac rhythm disturbance that is responsible for substantial morbidity and mortality independent of associated heart disease or other risk factors. Even in the absence of preexisting cardiovascular disease, AF remains significantly associated with excess mortality rates. The current unsatisfactory treatment for AF comes from lack of understanding of the pathophysiology of AF. The purpose of this study is to identify gene polymorphisms that confer susceptibility to atrial fibrillation. Patients with AF（N=500） and healthy volunteer（N=1000） without AF are enrolled in this study. Patients with coronary artery disease, severe valvular heart disease, cardiomyopathy or heart failure were excluded from the study.
