Atrial fibrillation after Coronary Artery Bypass Surgery with and without Cardiopulmonary Bypass

Abstract

Introduction:Postoperative arrhythmias are common complication after cardiac surgery. Incidence of postoperative AF varies between 10%-40% during the first postoperative week. 1 AF is the most common supraventricular arrhythmia following cardiac surgery. It ranges from 28%-54% of patients. 2 Incidence of atrialarrhythmia including AF after open heart surgery is between 20% and 50%. 3 20% to 40% of patients have AF after coronary artery bypass operation. 4 These variations in the incidence of AF depend on the patient population studied, type ofcardiac surgery, the definition of the arrhythmia and the duration of observation period. 5,6 After CABGthe etiology of AF is unknown, but may due to -unprotected ischemia, multi-

Systematic Review and Pooled Meta-analysis of the Current Status of Coronary Revascularization Surgery in Bangladesh

“…For the 14 prospective observational studies, 15,[18][19][20][21][22][23][24][25][26][27]30,31,35 there was high risk of bias in confounding factors. The non-ramdomized clinical trials 11,14,16,28,34 were also significantly biased due to absence of randomization. Additionally, the bias in selection of patients was observed in retrospective studies 17,33 which is typical of studies that are retrospective nature.…”
