BACKGROUND AND PURPOSE For patients having suffered ischemic stroke, the current diagnostic strategies often fail to detect atrial fibrillation as a potential cause of embolic events. The aim of the study was to identify paroxysmal atrial fibrillation in stroke patients. We hypothesized that patients with frequent atrial premature beats (APBs) recorded in 24-hour ECG will show more often atrial...
While management of atrial fibrillation (AF) patients is improved by guideline-conform application of anticoagulant therapy, rate control, rhythm control, and therapy of accompanying heart disease, the morbidity and mortality associated with AF remain unacceptably high. This paper describes the proceedings of the 3rd Atrial Fibrillation NETwork (AFNET)/European Heart Rhythm Association (EHRA) c...
Catheter ablation has emerged as an important therapy for the management of drug refractory symptomatic paroxysmal and persistent atrial fibrillation (AF). Although the elderly account for the majority of patients with AF, limited data exists regarding the use of catheter ablation for elderly patients with AF. As AF ablation has become more widespread, ablation techniques have improved and the ...
OBJECTIVE To review the effectiveness, safety, and costing of ablation methods to manage atrial fibrillation (AF). The ablation methods reviewed were catheter ablation and surgical ablation. CLINICAL NEED Atrial fibrillation is characterized by an irregular, usually rapid, heart rate that limits the ability of the atria to pump blood effectively to the ventricles. Atrial fibrillation can be a...
Introduction Atrial fibrillation (AF) is the most common significant cardiac arrhythmia, affecting an estimated four million people worldwide. Its rapid and uncoordinated atrial rhythm significantly compromises hemodynamics, decreases cardiac output, predisposes to ventricular arrhythmias, and sets the stage for thromboembolic complications. Contributing mechanisms are presumed to be the occurr...
Atrial fibrillation (AF) is the most common sustained arrhythmia and its treatment continues to be a challenge. Recently, delayed enhancement (DE)-MRI was introduced in the diagnosis and treatment of AF by the assessment of atrial fibrosis, which is considered the hallmark of the arrhythmogenic substrate in AF. Atrial fibrosis was reported to be an independent predictor of arrhythmia recurrence...
The prevalence of familial atrial fibrillation (AF) in the general population and structure AF is considered, genetic predictors pathogenetic mechanisms remodeling are analyzed. assessment risk occurrence, prediction its outcomes effectiveness therapy, as well prospects for gene therapy discussed.
Atrial fibrillation (AF) is common in patients who have implantable defibrillators and presents some unique challenges and opportunities. AF burden can be assessed more accurately, allowing for evaluation of therapy efficacy (drugs or ablation). It remains to be shown whether home monitoring of defibrillators to detect and treat AF more quickly can reduce cardiovascular and stroke end points. O...
Atrial fibrillation (AF) is a very common clinical problem, and presently available treatment options are suboptimal. A tremendous amount has been learned over the past 10 years about the atrial substrates that support sustained AF at the tissue, ionic and molecular levels. This understanding of the fundamental mechanisms underlying AF has opened up a variety of new, rationally-based therapeuti...
Atrial fibrillation (AF) can be found in an increasing number of cardiac surgical patients due to a higher patient's age and comorbidities. Atrial fibrillation is known, however, to be a risk factor for a greater mortality, and one aim of intraoperative AF treatment is to approximate early and long-term survival of AF patients to survival of patients with preoperative sinus rhythm. Today, surge...
