AIMS The aim of this prospective study was to evaluate left atrial (LA) function for the prediction of increased risk of new-onset non-valvular atrial fibrillation (AF). Risk stratification for new-onset AF based on LA remodelling may have a major public health impact. Although left atrial volume (LAV) or LA dimension have been proposed as predictors of AF, other predictive parameters of LA fun...
BACKGROUND It is critical to recognize high risk patients who are prone to develop stroke in the management of atrial fibrillation (AF). The purpose of this study was to identify the determinants of AF related stroke by assessing the anatomical and functional remodeling of cardiac chambers. METHODS We compared the cardiac structure and function of 28 consecutive patients with paroxysmal and p...
The relationship between the left atrial appendage (LAA) function, as assessed by transesophageal echocardiography, and the incidence of left atrial thrombus was evaluated in 62 patients with nonvalvular chronic atrial fibrillation (AF; n=50) and atrial flutter (AFL; n=12). It was hypothesized that in both AF and AFL not only the LAA flow velocity (LAAFV), but also the frequency of the LAA move...
BACKGROUND AND PURPOSE Atrial fibrillation (AF) has been associated with cognitive decline independent of stroke, suggesting additional effects of AF on the brain. We aimed to assess the association between AF and brain function and structure in a general elderly population. METHODS This is a cross-sectional analysis of 4251 nondemented participants (mean age, 76 ± 5 years) in the population-...
Abstract Background The RAte control Therapy Evaluation in permanent AF trial (RATE-AF; NCT02391337) was the first head-to-head controlled of beta-blockers versus digoxin patients with atrial fibrillation (AF) and symptoms heart failure. Patients randomised to had similar physical-related quality life rate, significantly improved functional class, reduced N-terminal pro-brain natriuretic peptid...
