NCT ID: NCT05204212 Not yet recruiting - Clinical trials for Non-valvular Atrial Fibrillation (NVAF): Paroxysmal, Persistent, Permanent

Left Atrial Appendage Closure in Patients With Non-valvular Atrial Fibrillation and End-stage Chronic KIDNEY Disease

LAA-KIDNEY
Start date: January 14, 2022
Phase: N/A
Study type: Interventional

In the proposed event driven trial, LAA closure devices will be compared in a 1:1 randomization to best medical care in AF patients at high risk of stroke and bleeding with ESKD. The trial will allow the use of the CE marked and clinically used LAA device Amplatzer Cardiac Plug and/or Amulet and all approved medical therapies in AF patients with ESKD including vitamin-K antagonists (VKA), NOACs as well as antiplatelet agents or no anticoagulation in excessive bleeding risk.

Biomarkers and Epigenetic Markers Associated With Pain in Patients With Symptomatic Atrial Fibrillation

PAIN
Start date: January 10, 2022
Phase:
Study type: Observational

Atrial fibrillation (AF) is the most common sustained arrhythmia and the number of patients with AF is expected to increase substantially in the coming decades. One third of patients with AF report no AF-associated symptoms, but up to one-fourth report severe symptoms. It is unclear why patients' experience of AF-related symptoms varies so much. We have previously shown that patients with symptomatic AF exhibit lower pain tolerance than patients with asymptomatic AF, as well as impaired pain inhibitory control and facilitated summation of pain, indicating that pain sensitisation may be of importance in symptomatic AF. In patients with chronic pain conditions, several biomarkers and epigenetic markers associated with generation and /or maintenance of chronic pain have been identified. Previous research of biomarkers and epigenetic markers associated with pain is sparse in patients with AF. The objective is to study levels of biomarkers and epigenetic markers in blood in patients with symptomatic paroxysmal AF (n=100), in relation to severity of AF symptoms, and compared to age- and sex-matched controls without AF (n=100). Blood will be obtained before and after AF ablation and levels of biomarkers, epigenetic markers and cardiac and inflammatory markers, analysed. Patients will complete an AF-specific symptom and a generic health-related quality of life questionnaire. In the future, biomarkers and epigenetic markers associated with pain may be used as a tool for evaluation of patients with AF and have an impact on individualized management. Another possibility is a rationale for future studies of novel analgesics that neutralize biomarkers or antagonizes its receptors.

NCT ID: NCT05200676 Not yet recruiting - Atrial Fibrillation Clinical Trials

Cardiac Arrhythmias in Greenland

Start date: February 1, 2022
Phase:
Study type: Observational

The study is a phd-study comprising several substudies focusing on cardiac arrhythmias, mainly atrial fibrillation, among Greenlanders in Greenland. Some previous studies have indicated that the prevalence may be lower than among Westerners, however; studies have also indicated that atrial fibrillation is underdiagnosed. These studies aim to: - Estimate the prevalence of AF among Greenlanders in Greenland aged 55 years or older. - Estimate the prevalence of well-known risk factors among those found to have AF - Explore the symptoms of those affected by AF in Greenland - Among part of the participants: estimate the prevalence of autonomic neuropathy as this may cause arrhythmias.

NCT ID: NCT05198492 Active, not recruiting - Atrial Fibrillation Clinical Trials

Short- and Long-term Health Effects of Air Pollution in Eastern Poland

EP-PARTICLES
Start date: January 1, 2022
Phase:
Study type: Observational

The effects of air pollution on the frequency of hospital admissions and mortality due to acute coronary syndromes, atrial fibrillation, and renal disfunction are noted also in areas perceived as pollution-free (due to the lack of large industry). The aim of the project is to assess the impact of air pollution in Eastern Poland on regional public health.

NCT ID: NCT05196412 Not yet recruiting - Atrial Fibrillation Clinical Trials

Screening of Cardiac Arrhythmias With Wrist-worn Aino ECG Cardiac Monitor

Start date: February 7, 2022
Phase: N/A
Study type: Interventional

The study investigates the performance pf PulseOn Arrhythmia Monitor System that includes a wrist-worn device, which combines continuous optical heartbeat interval monitoring and intermittent ECG measurement, and a data management system used by healthcare professionals for data observation, in the detection of previously undiagnosed cardiac arrhythmias, especially atrial fibrillation.

NCT ID: NCT05195268 Not yet recruiting - Atrial Fibrillation Clinical Trials

Reduction in Arrhythmia Burden With Left Atrial Posterior Wall Ablation for Persistent AF

RABLAP-AF
Start date: January 15, 2022
Phase: N/A
Study type: Interventional

RABLAP-AF will compare pulmonary vein isolation (PVI) in combination with posterior wall isolation (PWI) for patients with persistent atrial fibrillation (AF).

NCT ID: NCT05190679 Not yet recruiting - Atrial Fibrillation Clinical Trials

Prospective Phenotyping for Genetic Subtypes of Early-onset Atrial Fibrillation

Start date: March 2022
Phase:
Study type: Observational [Patient Registry]

This is a prospective, case-control study that seeks to learn about the role of genetics in early onset atrial fibrillation (AF) and if genetic testing can be used to improve how the investigators treat atrial fibrillation. The study will enroll 225 participants. Eligible participants will have undergone sequencing for arrhythmia and cardiomyopathy (CM) genes. Based on those results, participants will be recruited for an outpatient research visit with testing that includes cardiac MRI, rest/stress/signal-averaged ECGs, and cardiac monitoring. If an inherited arrhythmia/CM syndrome is diagnosed, guideline-directed changes to medical care will be recommended.

NCT ID: NCT05189691 Not yet recruiting - Atrial Fibrillation Clinical Trials

The Effect of Walking Exercises in Patients With Atrial Fibrillation

Start date: March 1, 2022
Phase: N/A
Study type: Interventional

This research will be carried out to determine the effect of walking exercises performed using a behavioral change model on symptom severity and quality of life in patients with Atrial Fibrillation.

NCT ID: NCT05185310 Recruiting - Atrial Fibrillation Clinical Trials

Strategies in Patients Undergoing Repeat AF Ablation

TRAP-AF
Start date: December 13, 2021
Phase: N/A
Study type: Interventional

The aim of the proposed research project is to compare the efficacy of three different ablation strategies in patients with atrial fibrillation (AF) who are undergoing their first repeat catheter ablation for recurrent AF.

NCT ID: NCT05181787 Recruiting - Stroke Clinical Trials

Biomarkers of Atrial Fibrillation Complicated With Stroke Based on Proteomics and Metabolomics

Start date: December 20, 2021
Phase:
Study type: Observational [Patient Registry]

Thrombus shedding in patients with atrial fibrillation (AF) can lead to cerebral artery embolism. Stroke caused by AF is very dangerous, which not only threatens the life of patients, but also seriously affects the quality of life. This study aims to explore the biomarkers of stroke in patients with AF by integrating proteomics and metabolomics data, and establish the network relationship of stroke in patients with AF, so as to reveal the molecular mechanism of stroke in patients with AF.
