Left Atrial Volume Index
Left atrial volume index is the strongest predictor of development of persistent atrial
fibrillation in obese non hypertensives.
Introduction: The global nature of the obesity epidemic was formally recognized by a
World Health Organization consultation in 1997(1). Prior epidemiologic studies have
yielded conflicting results regarding whether obesity is a risk factor for Atrial
fibrillation (AF), but these studies were potentially limited by short term follow up
and lack of echocardiography data(2). It is not sure if obesity itself predisposes to AF
and so hypothesizing such a link by suggesting that adiposity influences atrial and
ventricular structure(3), autonomic tone(4) and ventricular diastolic function(5). The
actual mechanism by which ... Show more content on Helpwriting.net ...
