Plasma miRNA-155 Levels Predict Atrial Fibrillation Recurrence after Cardioversion

Serum Levels of Vitamin E Are Associated with Early Recurrence of Atrial Fibrillation After Electrical Cardioversion

Serum levels of vitamin E are associated with early recurrence of atrial fibrillation after electric cardioversion.

BACKGROUND Oxidative stress is suggested to play a role in favoring the occurrence of atrial fibrillation (AF). We analyzed whether vitamin E, a known antioxidant, or markers of oxidative stress are associated with AF recurrence in patients undergoing electric cardioversion. METHODS AND RESULTS A total of 144 patients (83 men; mean age, 71.1±5.4 years) underwent successful biphasic electric c...

Noninvasive Predictors of Atrial Fibrillation Early Recurrence After Electrical Cardioversion and their Link to Atrial Remodeling

Several clinical factors have been studied to predict atrial fibrillation (AF) recurrence after electrical cardioversion (ECV) with limited predictive value. In this work, several time-frequency parameters from the fibrillatory (f) waves characterization were studied to improve ECV outcome prediction at mid follow-up. By analyzing ECV outcome one month after the procedure of 63 persistent AF pa...

Atrial Fibrillation Cycle Length and Atrial Size in Horses with and without Recurrence of Atrial Fibrillation after Electrical Cardioversion

BACKGROUND Atrial fibrillation (AF) cycle length (CL) and atrial size have been used in humans to characterize electrical and structural remodeling to predict outcome of cardioversion of AF and risk for AF recurrence (rAF). HYPOTHESIS Atrial fibrillation cycle length can be determined in horses with AF, and AFCL and atrial size are related to risk for rAF. ANIMALS Eighteen horses with natur...

Novel P Wave Indices to Predict Atrial Fibrillation Recurrence After Radiofrequency Ablation for Paroxysmal Atrial Fibrillation

BACKGROUND Circumferential pulmonary vein isolation (CPVI) is a widely used treatment for paroxysmal atrial fibrillation (AF). Several P wave duration (PWD) parameters have been suggested to predict post-ablation recurrence, but their use remains controversial. This study aimed to identify novel P wave indices that predict post-ablation AF recurrence. MATERIAL AND METHODS We selected 171 consec...
