BACKGROUND There is agreement that measurements of atrial volumes and ejection fraction (EF) are superior to atrial diameters for accurate determination of atrial size, follow up studies and prognosis. However, reference values for right atrial volumes and EF for cardiovascular magnetic resonance (CMR) have not been established but are crucial to identify patients with impaired right atrial fun...

Abstract Aims We sought to study the prognostic impact of right atrial (RA) size and function in patients with heart failure preserved ejection fraction (HFpEF) sinus rhythm (SR) vs. fibrillation (AF). Methods results Consecutive HFpEF were enrolled indexed RA volumes emptying fractions (RA-EF) assessed by cardiac magnetic resonance imaging (CMR). For SR during CMR feature tracking wall was per...

OBJECTIVES The purpose of this study was to evaluate left atrial mechanical function recovery and plasma atrial natriuretic peptide (ANP) release following successful cardioversion of persistent atrial fibrillation (AF). BACKGROUND Atrial fibrillation is characterized by functional deterioration, loss of atrial contraction, and elevation of plasma ANP levels. The response of ANP release towar...

Numerous known risk factors for atrial fibrillation (AF) exist, but few studies have investigated the link between gastrointestinal and liver disorders. Through a variety of pathways, hepatic conditions can increase both prevalent incident AF. According to numerous studies, dysfunction plays significant role in pathogenesis fibrillation. So, this review article aimed give an overview how functi...
