Echocardiographic Predictors of Atrial Fibrillation after Coronary Artery Bypass Grafting

Abstract

n the present study we aimed at determining the echocardiographic predictors of POAF in patients with CAD scheduled for coronary artery bypass graft to avoid over use of anti-arrhythmic drugs with their unwanted side effects. This study included 100 consecutive patients scheduled for coronary artery bypass grafting, their age ranged from 38-68years. They were assessed for base line characteristics, admission data, ECG (pre &post-operative), conventional echocardiographic parameters, TDI, LA strain % and LV global longitudinal strain (GLS %). They were classified into 2 groups, group I representing patients who developed POAF and group II representing patients who remained sinus in rhythm post –operatively during hospital stay.
