BACKGROUND Atrial fibrillation (AF) and chronic kidney disease (CKD) have both been shown to portend worse outcomes after acute myocardial infarction (MI); however, the benefit of a rhythm control strategy in patients with CKD post-MI is unclear. METHODS We prospectively studied 985 patients with new-onset AF post-MI in the GUSTO-III trial, of whom 413 (42%) had CKD (creatinine clearance < 60...
Atrial fibrillation (AF) is the most common sustained arrhythmia. Both the incidence and prevalence of AF are increasing, and the burden of AF is becoming huge. Many innovative advances have emerged in the past decade for the diagnosis and management of AF, including a new scoring system for the prediction of stroke and bleeding events, the introduction of non-vitamin K antagonist oral anticoag...
BACKGROUND Atrial fibrillation (AF) causes electrical, contractile, and structural remodeling of the atria. We investigated remodeling in patients undergoing AF ablation. METHODS Concomitant ablation of permanent AF, lasting 1 to 240 months, was performed in 73 patients (49.3% men) with a mean age of 66 +/- 9.1 years undergoing mitral valve operations. Electrical (AF cycle length from surface...
Acute atrial fibrillation (AF) is the most common cardiac rhythm encountered in clinical practice and is commonly seen in acutely ill patients in critical care. In the latter setting, AF may have two main clinical sequelae: (1) haemodynamic instability and (2) thromboembolism. The approach to the management of AF can broadly be divided into a rate control strategy or a rhythm control strategy, ...
Atrial fibrillation (AF) is a common rhythm in patients with acute decompensated heart failure (ADHF). Registry and trial data1,2 indicate that 20% to 35% of patients with ADHF who are admitted to the hospital will be in AF at presentation. In about one third of these patients, the AF will be of recent onset. Despite the high frequency with which the combination of AF and ADHF is encountered, t...
BACKGROUND There are two treatment strategies for medication-resistant atrial fibrillation (AF): rhythm control or rate control. It has been suggested that rate control is a valid strategy in well-tolerated AF because it does not result in increased mortality. We aimed to investigate the 1-year outcome of rhythm control in an elderly population of AF patients. METHOD The study was retrospecti...
See related article, page 265. Atrial fibrillation (AF) is widely recognized as the most common cause of cardioembolic stroke in those aged 55 years. Less well appreciated are silent embolic infarcts and their impact on cognitive decline and vascular dementia. Hence, the prevention of both clinical and silent brain infarcts is the primary goal of effective AF treatment. Indeed, entire industrie...
BACKGROUND The objective of the present study was to evaluate the relation between freedom from atrial fibrillation (AF) and left atrial (LA) size in patients who underwent circumferential pulmonary vein (PV) isolation and LA ablation. METHODS AND RESULTS One hundred five consecutive patients with symptomatic and drug-refractory paroxysmal or persistent AF were included in the present study. ...
Atrial fibrillation (AF) is a supraventricular tachyarrhythmia where uncoordinated atrial electrical activity results in ineffectual atrial mechanical action and irregular ventricular response. AF is the commonest sustained arrhythmia and its prevalence increases with age. AF is often associated with underlying structural or functional heart disease, but there may not be any detectable heart di...
Atrial fibrillation (AF) is the most common sustained arrhythmia associated with increased morbidity and mortality. Efficacy and safety of currently employed antiarrhythmic drugs (AADs) continue to be less optimal in AF. Development of newer AADs has recently been made possible through a greater understanding of electro-pathophysiology of AF. Highly specific drugs acting on atria are currently ...
