Active clinical trials for "Atrial Fibrillation"

Postoperative Atrial Fibrillation (POAF) is one of the most common complications following coronary artery bypass grafting (CABG) occurring to 20% - 40% of patients. It is associated with prolonged hospitalization, increased hospital costs, increased complications and mortality rate. Despite the use of Beta Blockers, approximately 20% of patients develop atrial fibrillation following CABG surgery, suggesting a role for polymorphism in the genes The aim of the present study is to determine the minor allele frequency of some of the genes that affect the beta blockers' response and to determine the association between polymorphism in these genes and the occurrence of postoperative atrial fibrillation after coronary artery bypass grafting in Egyptian patients receiving perioperative beta blockers.

In the presented study, autonomic function as well as risk for atrial fibrillation will be assessed to characterize the relation between risk of atrial fibrillation and autonomic function.

A non-interventional, national longitudinal study of atrial fibrillation performed with 91 cardiologists.

The primary purpose of the study is to evaluate treatment of new onset atrial fibrillation in french ICU.

Patients undergoing coronary artery bypass grafting (CABG), aortic (valve) or mitral valve surgery are at risk of developing postoperative and new-onset atrial fibrillation (AF), but adequate risk prediction is currently impossible. This study aims to discover tissue and circulating microRNAs and protein biomarkers that may help to unravel the pathophysiological processes underlying AF and are potential tools for risk stratification and prognosis or may become future targets of therapy. This study will be a single-center cohort study of 150 patients undergoing cardiac surgery, which will constitute the beginning of the follow-up period. Left atrial appendages, whole blood and epicardial mappings will be collected. Patients will be followed for 2 years with regular holter investigations to detect postoperative and new-onset AF.

Pharmacists are in the best position to counsel and educate patients on anticoagulant agents such as NOACs. This should enable patients to play a more active role in their treatment and ultimately enhance adherence behaviour. However, educational elements should be targeted to knowledge. Thus, the investigators will develop and validate a questionnaire that can assess knowledge about NOACs

This is a 2x2 study examining the impacts of a novel exercise regimen and daily text message reminders in patients at high risk for cardiovascular disease. Patients participating in cardiac rehabilitation will be randomized to either moderate intensity continuous training (MICT) or a novel exercise regimen consisting of three periods of high intensity exercise, called BURST exercise. Additionally, half of the patients in each exercise group will be randomized to receive daily text message reminders to improve adherence to the prescribed exercise regimen.

The primary purpose of this study is to evaluate the risk of major bleeding and stroke/systemic embolism (SE) among novel oral anti-coagulant (OAC) naïve and warfarin naïve Medicare Advantage patients with non-valvular atrial fibrillation (NVAF) treated with apixaban, dabigatran, rivaroxaban, or warfarin.

The primary objective of the study is to describe the usage of NOACs in patients with NVAF, in the hospital setting, based on the baseline characteristics at the time of first NOAC initiation.

The primary objective of this research is to determine if evaluating CIEDs using CareLink Express® can lead to shorter time to interrogation in the Emergency Department compared to evaluation of devices using traditional evaluation procedures. The goal of the research is to determine if patients evaluated by CareLink Express® have a reduction of "time to interrogation" compared to the traditional patient cohort. Secondary objectives of the study are to determine any significant differences in the two populations regarding: Health care resource utilization including total charges for ED care. Number of patients leaving the ED without being seen (LWBS) or left without the device interrogation completed. Device related issues detected.
