Atrial fibrillation in aging population

Triple threat: adiposity, aging, atrial fibrillation

Atrial fibrillation in the heart failure population.

Atrial fibrillation (AF) is the most common chronic arrhythmia. Incidence of AF in the heart failure population is high--10% to 30%--and is associated with a reduction in exercise capacity and a poor long-term prognosis. Management of AF includes 4 strategies: control of heart rate, termination of AF/conversion back to sinus rhythm, prevention of recurrences, and prevention of thromboembolic ev...

Substance Abuse in Aging Population

substance abuse' specially opiates and prescribed drugs are spreading among the older adults. Most of the time it begins as an attempt to medicate chronic pains, medical conditions and loneliness. In other instances, it simply is the continuation of a problem that begun in young adulthood. But scholars and specialists in both fields of Addiction and Gerontology, rather neglected this fast growi...

Aging Modulates the Substrate and Triggers Remodeling in Atrial Fibrillation.

Aging plays a critical role in the genesis of atrial fibrillation (AF) and also increases the risks of cardiac dysfunction and stroke in AF patients. AF is caused by increased AF triggering from abnormalities of the thoracic vein and/or modulated substrate (atrial) with enhancement of AF maintenance. Clinical and laboratory evidence indicates that aging is significant in the creation of atrial ...

Protective effects of simvastatin on atrioventricular node during simulated experimental atrial fibrillation in vitro

Introduction: Recent evidence has indicated that statins can reduce the incidence of both supraventricular and ventricular arrhythmias with various mechanisms. The primary goal of the present study was to determine direct protective role of simvastatin in modifying concealed conduction and the zone of concealment in a simulated model of atrial fibrillation (AF) in an isolated atrioventricula...
