Filter by:This study is being conducted to collect data on the management of gastrointestinal and urogenital bleeding events occurring in patients with atrial fibrillation taking dabigatran etexilate.
Prospective Randomized Study on Clinical Effectiveness of Carvo-Tricuspid Isthmus (CTI) Block in Patients with Paroxysmal Atrial Fibrillation (PAF) will be performed. Study will be composed with two arms including 4 pulmonary vein isolation and pulmonary vein isolation with CTI block. After that all patients will be followed up by HRS(Heart Rhythm Society) 2010 expert consensus guideline.
The purpose of this study is to assess whether the switch from branded to generic warfarin or between different generic warfarin tablets may cause fluctuation in the results of coagulation tests (International Normalized Rate, acronym INR) in patients, thus predisposing them to unnecessary risks.
Investigators seek to observe the long term patterns of arrhythmias detected by permanent pacemakers.
The proposed study will validate the clinical use of new biomarker blood tests to identify blood components that may differentiate between diverse stroke etiologies and clinical outcomes as listed below: 1. Differentiate between cardioembolic and large artery atherosclerotic ischemic strokes, when hemorrhagic stroke is ruled out. 2. In cases of ischemic strokes of unknown or "cryptogenic" etiology, determine the ability of biomarker blood tests to predict etiology between cardioembolic and large artery atherosclerotic. 3. In cases of cardioembolic ischemic stroke, further differentiation of cardioembolic ischemic strokes into those caused by atrial fibrillation (AF) and those not caused by AF. 4. Differentiate "transient ischemic attacks" (TIAs) from acute ischemic strokes. 5. Differentiate TIAs from non-ischemic "transient neurological events" (TNE) with similar symptoms.
The purpose of this study is to determine the frequency of atrial fibrillation in patients with transient ischemic attack (TIA). Patients suffering TIA will have their heart rhythm extensively monitored with 72-hour Holter-monitoring and an implantable loop-recorder. Furthermore, the patients will be examined with echocardiography, coronary calcium-score and biomarkers with the purpose to predict which subjects at risk for developing atrial fibrillation.
Atrial fibrillation and chronic neuropathic pain are adverse events occurring after posterolateral thoracotomy for lung resection. The continuous application of magnesium sulphate may have a prophylactic effect. The investigators record the incidence of atrial fibrillation during a seven day period after thoracotomy as well as the incidence of chronic neuropathic pain during a three months period, comparing one group with a continuous application of magnesium sulphate against one group without magnesium sulphate.
The primary objectives of this study are: - To estimate the incidence rate of unexpected adverse events - To characterize the bleeding events and assess risk factors of bleeding - To identify ancillary baseline variables that may also be associated with adverse outcomes
Silent atrial fibrillation is an important cause of unnecessary strokes. If diagnosed and treated in time with anticoagulants, many disabling strokes can be prevented. In order to improve the diagnosis of atrial fibrillation the MyDiagnostick is developed; a user friendly and easy to use stick that diagnoses atrial fibrillation in one minute. During influenza vaccination, many patients who are also at risk for atrial fibrillation visit the general practice. This offers an ideal opportunity for screening for atrial fibrillation. The study investigates the yield of screening for atrial fibrillation with the MyDiagnostick during influenza vaccination (newly detected atrial fibrillation with corresponding CHA2DS2-Vasc score).
Atrial fibrillation remains a major cause of morbidity following cardiac surgery with cardiopulmonary bypass. Many mechanisms have been implicated. Among then, adenosine, a strong endogenous vasodilating agent has been involved in cardiac surgery-induced atrial fibrillation, via A2A receptors modulation. The effects of caffeine on the inducibility of atrial fibrillation are actually well-known, leading then to a significant reduction of atrial fibrillation. Moreover, a recent clinical study has demonstrated that coffee drinking was inversely associated with total and cause-specific mortality. The investigators therefore examined the preventive effects of oral caffeine on valvular surgery with cardiopulmonary bypass-induced atrial fibrillation. The investigators also evaluated prospectively the influence of caffeine on adenosine plasma levels and A2A adenosine receptors modulation.
