ABSTRACT… Introduction: Atrial Fibrillation (AF) is one of the most common arrhythmia after coronary artery bypass grafting (CABG). Many risk factors have been identified for the development of postoperative AF with varied level of evidence. AF is associated with increased risk of morbidity and mortality causing prolong hospital stay and utilizing more resources. Our study was aimed to identify high risk population for developing post-operative AF and to draw recommendations for its prevention. Objectives: Our objective was to determine the frequency of Atrial Fibrillation (AF) and its predisposing factors in patients after Coronary Artery Bypass Grafting (CABG). Setting: The study was conducted at Cardiac Surgery Department / Faisalabad Institute of Cardiology, Faisalabad. Duration of Study: 15-12-2014 to 14-07-2015. Study Design: Cross sectional study. Results: The result showed that out of 130 patients undergoing CABG surgery, 104 (80.3%) male and 26 (19.7%) females, 9(7%) patients suffered AF in post-operative phase. A significant association was found between postoperative AF and advanced age (p = 0.011), obesity (p = 0.028), low EF (p = 0.000), and post-operative use of β-blocker (p = 0.007). Significant difference was found between postoperative AF and days stayed in hospital (p = 0.000) and magnesium level at first day (p = 0.038). On the other hand there was no significant relationship found between AF and prolongs cross clamp and bypass time. Conclusion: Advance age, obesity, congestive heart failure, low ejection fraction and withdrawal from beta blockers in post-operative period have been identified as a significant risk factors for the development of post-operative atrial fibrillation. Key words:Atrial Fibrillation, Coronary Artery Bypass Grafting, Postoperative Arrhythmia. Article Citation: Riaz R, Ahmad N, Abbas S.

“…The important risk factors identified include smoking, increased age, atrial enlargement, reduced left ventricular function (especially if ejection fraction is less than 40%), preoperative arrhythmias and angina pectoris [3,4,5,6,7]. There are also other factors that could influence the frequency of early post-operative arrhythmias, such as previous medications, concomitant medications during general anaesthesia, previous diseases, etc.…”

“…Postoperative AF is accompanied by higher morbidity including HF and stroke, and consecutively longer hospitalization, mortality, and increased costs. 43 In addition, first diagnosis of AF after surgery predisposes to recurrent AF during later life. Most known risk parameters for postoperative AF are derived from cardiac or thoracic surgery experience.…”

Atrial fibrillation (AF) is a complex disease with increasing prevalence in an aging population and longer survival with cardiovascular diseases. Whereas most clinical efforts have been aimed at predicting risk of AF sequelae such as stroke and heart failure, little is known on primary prevention. AF risk assessment is complicated by the existence of distinct subtypes of AF, such as lone AF or postoperative AF, in contrast to common AF in the elderly. Due to its often intermittent nature, diagnosing AF can be a challenge. Risk prediction becomes reasonable when specific interventions arise. Due to our limited understanding of AF pathophysiology and substantial lack of specific preventive strategies in the population, modification of the general cardiovascular risk profile has largely remained the only option. Initial attempts at combining established risk factors for AF such as age, sex, hypertension, body mass index, electrocardiographic characteristics, and cardiovascular disease in a riskprediction instrument have produced a robust algorithm. However, known risk factors only explain a fraction of the population-attributable risk of AF, and the search for novel risk indicators is ongoing. More efficient monitoring for electrocardiographic precursors of AF and the field of genomics are evolving areas of AF risk factor research. A better understanding of the underlying substrate of AF will provide targets for prevention. In the future, clinical trials will be needed to establish risk categories, interventions, and their efficacy. Despite a relevant public-health impact, knowledge on risk prediction and primary prevention of AF is still limited today.
