Active clinical trials for "Atrial Fibrillation"

Post Marketing study, Interventional, Prospective, non randomised Describe how the MD is using the information of the ICM in addition of standard FU(clinical exam and holter 24h)post AF ablation(1 year FU).

The purpose of this prospective observational study (registry) is to determine the acute success rate of a complex fractionated atrial electrogram (CFAE) guided ablation procedure using a dedicated software and to determine the functionality and performance of the CFAE software in patients with a type of persistent atrial fibrillation (AF) in routine clinical practice.

The purpose of this study is to assess the efficacy of minimally invasive surgery for atrial fibrillation.

We are performing a research study to learn more about the control of an individual's blood thinning (anticoagulation) on warfarin. Individuals from an anticoagulation clinic are being asked to participate in order to see if a lottery which provides the opportunity to win money in combination with the use of the Med-eMonitor might be useful in helping patients to achieve better control of their anticoagulation therapy. Half of the participants will be enrolled in the lottery arm and the other half will be a control group who will receive the Med-eMonitor only.

This non-interventional prospective study is a post-authorization safety study (PASS) of vernakalant conducted to collect information about normal conditions of use and appropriate dosing, and to quantify possible medically significant risks associated with the use of vernakalant in real-world clinical practice.

The purpose of this trial is to determine if by structured telephone based health coaching programme supported by remote monitoring system among type 2 diabetes, coronary artery disease and heart failure patients the investigators are able to improve their quality of life as measured by the SF-36 questionnaire and reduce a value of HbA1c under 6,5 % among those type 2 diabetes patients who had elevated value of HbA1c when recruited.

The atrial fibrillation is the most frequent confusions of the heart rhythm: his preValencia increases with the age, and the investigators consider that beyond 65 years, 5 % of the population is affected by this arrhythmia. It entails a greater risk of morbidity (thromboembolic accident and cardiac insufficiency) and of cardiovascular mortality (mortality increased by a factor 1,7 - 2) independents of the causal pathology or the associated risk factors. For all these reasons, it raises a real problem of public health.

Atrial fibrillation is an abnormal heart beat that starts in the upper parts of the heart and can cause stroke or death, if untreated. In general, treatments are not very effective, with frequent relapses of the abnormal heart beats. One explanation for the high relapse rate is that the treatments might not address the underlying cause of atrial fibrillation. Recently, the investigators have found that atrial fibrillation is associated with increased oxidative stress. This is a condition where abnormal oxygen forms are produced. These forms harm the cells of the heart, causing them to beat abnormally. The investigators have found increased oxidative stress in pig and mouse models of atrial fibrillation. They would like to see if oxidative stress is present in humans with atrial fibrillation. In this study, they will compare blood markers of oxidative stress between patients with and without atrial fibrillation. It is the expectation that participants with atrial fibrillation will have more abnormal blood markers of atrial fibrillation. This study requires participants to visit their doctors, undergo a history and physical examination, and give blood only once.

This is a prospective observational cohort study that is in the process of enrolling and following patients on warfarin therapy by utilizing anticoagulation clinics in VA hospitals across the US. There are currently 14 sites actively enrolling patients in the study. For each octogenarian enrolled a randomly selected patient with atrial fibrillation (AF) younger than 80 years of age from the same clinic and receiving warfarin for approximately the same duration is enrolled.

Atrial fibrillation (AF) is more common in patients with renal disease compared to the general population an risk increase to as much as 10 times in patients on hemodialysis (HD). Stroke is an important cause of morbidity, mortality and suffering for patients with end-stage chronic kidney disease (ESCKD) on hemodialysis.The risk of bleeding in these patients can be roughly 5-fold higher that without it. Current guidelines recommend the use of oral anticoagulants (AO) to prevent stroke or systemic thromboembolism in high-risk patients with AF. Left atrial appendage occlusion (LAAO) reduces the risk of bleeding while allows thromboembolic stroke prevention. The aim of the study is to assess the procedural safety on stroke and bleeding prevention of LAAC in patients with non-valvular atrial fibrillation (NVAF) and ESCKD on HD.
