Active clinical trials for "Atrial Fibrillation"

The overall objective of the project is to develop a collaboration model between the patient, the patient's General Practitioner (GP) and the cardiologist at the hospital in a seamless collaborative model dubbed the "Cardio-relay model". The specific purpose of the pilot project is to ease performing heart rhythm monitoring with focus on diagnosis and evaluation of atrial fibrillation (AF), for patients who have difficulties to attend repeated visits to the hospital-based outpatient clinic. With available eHealth technologies the cardiologist can access data gathered at the patient's side to provide support to the GP for selecting patients with need for heart rhythm monitoring, plan further evaluations and guide therapeutic decisions. These patients can thereby receive support that without the burden of attending physical meetings at the cardiologist office. The investigators evaluate if the cardio-relay model allows to complete evaluation of frail patients compared to usual care and if patients experience are sufficiently confident accessing the cardiologist through the cardio-relay model.

To investigate the safety and efficacy of long-term use of Prazaxa® Capsules in patients with nonvalvular atrial fibrillation for preventing the occurrence of ischemic stroke or systemic embolism (SEE).

This is a 2- component, single center study, witch aims to evaluate the efficacy of multisite intracardiac echocardiography (mICE) imaging of left atrial appendage (LAA) and in detecting thrombus located in LAA as compared to transesophageal echocardiography (TEE). The study group will consist of patients eligible for atrial fibrillation (AF) ablation procedure (Component I) or cardioversion (Component II). First component will enroll 100 patients; these patients will undergo clinically indicated TEE & cardiac catheterization procedures with ICE(AF ablation). Second component will enroll 15-20 patients with AF or atrial flutter in whom a thrombus in LAA was detected by TEE prior to electrical cardioversion. The ICE probe will be located in multiple positions in the right atrium (RA), coronary sinus (CS), pulmonary artery (PA), right ventricular outflow tract (RVOT) and esophagus. This will enable the investigators to compare sensitivity and specificity of mICE and TEE. This study will examine two hypotheses in AF patients undergoing invasive cardiac procedures: Hypothesis 1: That ICE has comparable efficacy to TEE in visualization of LAA from multiple positions (RA,CS,PA,RVOT and esophagus ). This will be evaluated during the component I of the study. Hypothesis 2: That ICE can identify low risk patients, CHADS Score < 2,0 in whom immediate cardioversion during the procedure is as safe as based on conventional strategy.

Atrial fibrillation is the most common arrhythmic complication after coronary artery bypass grafting (CABG). Post operative atrial fibrillation (POAF) increases morbidity and mortality. Inflammation could be a factor in POAF and recent evidence of remotely inducing ischemia may reduce inflammation and cardiac injury. The investigators plan to use a blood pressure cuff on the arm as a method to produce remote ischemia and assess the occurrence of POAF for seven day.

The purpose of this research study is to see if a lottery which provides the opportunity to win money, a reminder system using a "Med-eMonitor", or the combination of both might be useful in helping patients to achieve better control of their anticoagulation therapy. Selection for the arms of the study is randomized by the study computer. Some will participate in the daily lottery only, some with the reminder system only, some with the reminder system and the daily lottery, and some with neither the lottery nor the reminder system.

It is well known that atrial fibrillation (AF) and atrial flutter occur frequently after most types of cardiac surgeries.(1-4) Postoperative AF is associated with significant morbidity, longer hospital stay, and higher related costs. Currently, it is common procedure to premedicate patients with antiarrhythmic drugs for elective cardiac surgeries. Treatments such as beta blockers, Amiodarone, and electrical pacing are used to help prevent the morbidity associated with pot-operative AF.(5) Renin-angiotensin system (RAS) activation may contribute to AF. Several clinical trials have suggested that inhibitors of this system may reduce the incidence of AF.(6-12) Patients with AF are known to have increased levels of angiotensin converting enzyme (ACE) and some types of angiotensin receptors.(13-15) Data from animal studies performed by our group suggest that cardiac ACE overexpression may lead to arrhythmic ion channel changes.(16;17) Although not studied in this group yet, it would be reasonable to conclude that the use of ACE inhibitors and angiotensin receptor blockers (ARBs) would decrease the incidence of AF in post-operative patients, too

The purpose of this study is to determine the optimal images of the heart structures which are used to guide AF ablation or BiVenticle and coronary vessels.

Current Knowledge: Countless studies have been conducted to study the relationship between OSA and AF, and a significant association has been established between both diseases, owing to the numerous shared risk factors and a wide variety of pathophysiological changes resulting from both diseases being relevant to each other. Our study inspects this relationship from a cardiovascular standpoint, examining the prevalence of OSA in existing AF patients, which could be interpreted as AF being a risk factor for OSA development.

This is a national, multi-center, prospective study to evaluate the safety of Edoxaban in patients diagnosed with AF who are currently using Edoxaban for stroke prevention. The primary objective: To evaluate safety of Edoxaban treatment in patients with atrial fibrillation (AF) on Edoxaban therapy in routine clinical practice in Turkey.

In people with type 2 diabetes, the body does not make enough of a hormone called insulin or does not use insulin well. This results in high blood sugar levels. People with diabetes are more likely to have non-valvular atrial fibrillation (NVAF) compared to people who do not have diabetes. Having both NVAF and diabetes can increase the chances of developing other serious health conditions, like blood clots and strokes. People with NVAF may receive treatments to help lower the risk of blood clots. This can then help to lower the risk of having a stroke. Two of these treatments are rivaroxaban and warfarin. In this study, the researchers will look at how well rivaroxaban works and how safe it is compared to warfarin in routine clinical practice. The study will include men and women who are at least age 18 and who have NVAF and type 2 diabetes. The researchers in this study will use the participants' health information from an electronic database.
