Active clinical trials for "Atrial Fibrillation"

There are a wide range of significant epidemiological, clinical, and operative predictors for the development of post-CABG AF including older age, female gender, large LA diameter, higher CHA2DS2-VASc score, valve replacement and postoperative inotropic support. Nevertheless, further large-scale studies are still needed to confirm our findings

The aim of this study is to quantify and characterize the outcomes of radiofrequency (RF) ablation after, and the utility of, electroanatomical mapping with the market-released HD mapping catheters Inquiry™ AFocusII™ Double Loop and Advisor™ HD Grid, Sensor Enabled™ with the EnSite Cardiac Mapping System and the EnSite Automap module in subjects with AF in the real-world environment of the Asian population.

In this part of the Registry Program patients with non-valvular atrial fibrillation (AF) at risk for stroke are enrolled to characterize the target population and to collect real world data on important outcome events. For administrative purposes the study is divided into two protocol numbers: 1160.129 for all non-EU (European Union) and non-EEA (European Economic Area) countries, and 1160.136 for EU and EEA countries. The total number of patients enrolled in both protocols is estimated to be 48,000 patients, and all these patients will be included in the data analysis for study 1160.129.

The aim of the study is to assess the incidence of patients suffering from ischemic stroke or transient ischemic attacks who have underlying asymptomatic paroxysmal atrial fibrillation. Patients who have suffered an ischemic stroke or transient ischemic attack, without a history of atrial fibrillation, are planned to be included. Starting within 14 days of the ischemic stroke, participating patients are asked to perform 10 second ECG recordings using a handheld ECG device twice daily (mornings and evenings) during 30 days. These recordings are transmitted via telephone to a secure encrypted Internet site. Within these 30 days the participants also perform an ambulatory 24 hour Holter recording. Handheld ECG recordings are evaluated continuously. In case of atrial fibrillation the patient is informed and offered treatment with anti coagulant medication (Warfarin). The investigation is a comparison between 24 hour continuous ECG recordings and short intermittent ECG recordings twice daily over a longer time period to determine which method is the best to detect atrial fibrillation in this patient group. Hypothesis: Short Intermittent ECG recordings over a longer time period is more efficient, compared with continuous 24 hour ECG recordings, in detecting silent paroxysmal AF in patients with an ischemic stroke and without a history of atrial fibrillation.

The objective of this study is to determine whether the finger tip images captured by the EPIC ClearView device, when analyzed via the ClearView software, produce a Response Scale that characterizes trends consistent with known diagnoses identified by medical doctors. Specifically, the investigators hypothesize that the organ system involving any of a series of known active diagnoses will be identified in the EPIC ClearView Response Scale report with the intention of providing potential triage capabilities.

This study constitutes Phase I of the Registry Program. The main objective of this study is to characterize the newly diagnosed non-valvular AF patient population at risk for stroke and the selection of antithrombotic treatment for stroke prevention in a real-world setting before dabigatran etexilate is approved for the prevention of strokes and systemic emboli in patients with non-valvular AF in different regions of the world.

The Global Anticoagulant Registry in the FIELD-Atrial Fibrillation (GARFIELD-AF Registry) is a non-interventional, observational study that characterized a global population of non-valvular atrial fibrillation patients. The registry was used to document global baseline characteristics, current treatment strategies and outcome measures. Characterisation of a number of AF sub-populations was also completed. GARFIELD-AF is an independent academic research initiative sponsored by the Thrombosis Research Institute (London, UK) and supported by an unrestricted research grant from Bayer AG (Berlin, Germany).

Primary objective shared by the 3 registries : Describe the different pharmacotherapeutic management in patients : DB (Diabetes): with type 2 diabetes, treated with oral and / or injectable antidiabetics CP (Chronic Pain): with any disease leading to chronic pain (lasting for more than 3 months) AF (Atrial Fibrillation): with ongoing AF or AF diagnosed within 12 months before enrollment Secondary objectives shared by the 3 observatories: Describe the occurrence of clinical events, hospitalizations and death, according to the different medical care conditions, and analyze their predicting factors Estimate the resources consumption according to the medical and non medical management of these patients, Analyze the impact of some factors (patient's cognitive status, autonomy, renal function ...) on the current practice Secondary objectives specific shared by DB and AF registries : - Analyze the geriatric pharmaco-genetic aspects Specific secondary objectives for each observatory : DB : Describe HbA1c level, percentage of responders and body weight evolution according to the different medical care conditions CP : Evaluate pain consequences on Daily Living Activities and patient autonomy

The primary objective of this study is to analyze the diagnostic accuracy of coronary CT angiography using 320 simultaneous detector results in patients with atrial fibrillation.

The purpose of this study is to prospectively follow the next 200 patients who undergo catheter ablation of atrial fibrillation for symptoms and signs of esophageal injury.
