Objective(s): Drug-induced atrial fibrillation (AF) is considered an adverse effect of chemotherapeutic drugs. AF is a crucial risk factor for stroke, heart failure, myocardial infarction, and mortality. Pulmonary veins (PVs) are considered triggers inducing AF, and the sinoatrial node (SAN) may modulate PV activity and participate in AF genesis. AF was associated with...

Background—The substrates for human atrial fibrillation (AF) are poorly understood, but involve abnormal repolarization (action potential duration [APD]). We hypothesized that beat-to-beat oscillations in APD may explain AF substrates, and why vulnerability to AF forms a spectrum from control subjects without AF to patients with paroxysmal then persistent AF. Methods and Results—In 33 subjects ...

AIMS The aim of this study was to investigate the change in plasma brain natriuretic peptide (BNP) level after pulmonary vein isolation (PVI) in paroxysmal (PAF), persistent (Pers-AF), and permanent atrial fibrillation (AF) (Perm-AF) patients. METHODS AND RESULTS In 96 lone AF patients (PAF=65, Pers-AF=17, and Perm-AF=14), BNP was measured before and 3 months after successful PVIs. At baselin...

Background and purpose: Atrial fibrillation (AF) is a major cause of mortality and morbidity in patients after coronary artery bypass graft (CABG). Attempt for knowing indices and factor influence post CABG AF may help in finding patients at risk and prevent more complications. This study aimed to evaluate the association between diastolic dysfunction indices and grading with post CABG AF durin...
