POST-OPERATIVE ATRIAL FIBRILLATION; INCIDENCE AFTER CORONARY ARTERY BYPASS GRAFT SURGERY
Atrial fibrillation is the most common arrhythmia observed following Coronary Artery Bypass Graft surgery. Objectives: To determine the incidence of post-operative atrial fibrillation in patients undergoing coronary artery bypass grafting. Materials and Methods: Study Design: Non-randomized prospective. Setting: Cardiac Surgery Department of Multan Institute of Cardiology, Multan. Period: 20-1-2014 to 01-05-2015. A total number of four hundred and ninety (490) patients having age more than 40 years undergoing isolated coronary artery bypass graft surgery were included in the study. Data was analyzed in SPSS V20 software. Frequency and percentages were used for Atrial Fibrillation. To see the impact of AF on morbidity, patients developing AF was compared with those who do not develop Atrial Fibrillation post-operatively using independent sample t-test for quantitative variables. Chi-square test and Fischer's Exact test (whenever appropriate) was used to compare qualitative variables. Results: A total number of four hundred and ninety (490) patients were included in this study. There were more 431 males (88.0%) in this study. of the patients 71.6% were in LV Grade I before surgery. Incidence of post-operative atrial fibrillation was 13.5%. In 4.5% patients IABP was inserted due to hemodynamic instability. Ventilation time and hospital stay time was significantly higher in patients with AF postoperatively (p value 0.03 and 0.02 respectively). But duration of inotropic support, post-op CKMB levels and IABP use were not significantly different in both groups. Conclusion: The incidence of post-operative Atrial Fibrillation is 13.5% according to this study. And these patients were associated with increased risk of morbidity.
Time of Occurrence and Duration of Atrial Fibrillation Following Coronary Artery Bypass Grafting
Medical Archives, 2016
Introduction: Dilatation of the left atrium and left ventricular diastolic dysfunction (DDLV) according to recent studies has significance in the occurrence of postoperative atrial fibrillation (AF), stroke and death. Authors of some studies found no relationship between these parameters and atrial fibrillation. Objective: this study is to determine the time of occurrence and duration of atrial fibrillation in patients after surgical revascularization (CABG) due to the presence of left ventricular diastolic dysfunction and left atrium dilatation and identify the most significant predictors of incident AF. Methods: Prospective study included 116 patients undergoing surgical myocardial revascularization followed from admission to discharge. The study was conducted at the Special Hospital "Heart Center BH" Tuzla for a period of one year (March 2011/2012 g.). For all patients was performed preoperative ultrasound examination, especially parameters of diastolic function of the left ventricle and left atrium volume index (LAVi), as the best parameter sized left atrium, and the postoperative occurrence of certain AF and day occurrence, duration in hours, the number of attacks. To assess whether an event occurred or not was used logistic regression, and the effect of time on the event of interest is analyzed by Cox 's regression hazard parallel. Results: 75.9 % of patients had DDLV, and 91.4 % were hypertensives, 12.9 % from the previous stroke (ICV) and 42.2 % diabetics (DM), 14 % with COPD. The average age of patients was 61.41 ± 4.69 years. In both groups was 32.8 % women and 67.2 % men. LAVi preoperative values were significantly higher as DDLV greater degree. In patients with DDLV and higher values LAVi risk of AF is higher, the greater the length of AF and significantly higher number of attacks FA. Early occurrence of atrial fibrillation and its longer duration in function with increasing LAVi a marked increase in the value LAVi have the greatest hazard for the early appearance of atrial fibrillation. As a result of analysis of the most significant predictors of AF are: DDLV and LAVi. Conclusion: Postoperative atrial fibrillation occurs earlier and lasts longer in patients with DDLV and elevated left atrial volume index especially LAV > 36ml/ m2. LAVi has the best explanation of the function of hazard occurrence of atrial fibrillation after CABG.
Predictors of Postoperative Atrial Fibrillation After Coronary Artery Bypass Graft Surgery
Indian Pacing and …, 2008
The present study was aimed to identify the preoperative, intraoperative, and postoperative predictors of AF in a pure cohort of the patients with coronary artery disease who underwent CABG surgery. Methods Between November 2005 and May 2006, 302 consecutive patients were included in this prospective study. All the relevant clinical, electrocardiographic, echocardiographic, and laboratory data were gathered in the included patients and they were also monitored for development of post-CABG AF. Results Postoperative AF occurred in 46 (15%) of patients. By univariate analysis, older age, P-wave abnormality in ECG, presence of mitral regurgitation, larger left atrium (LA), left main coronary artery involvement, failure to graft right coronary artery (RCA), and adrenergic use in ICU were significantly associated with occurrence of post-CABG AF (all P< 0.05).

Background— Atrial fibrillation (AF) is the commonest complication during cardiac surgery, however, the long-term prevalence of AF following surgery and its clinical consequences remain unclear. Patients and Methods— To investigate this, 877 consecutive patients undergoing first time CABG were followed for 1 year. Rhythm disturbances were diagnosed from serial ECGs and documented notes. The arrhythmia was treated medically and/or by cardioversion. Results— Out of 877, 17 patients (1.9%) died in the hospital and out of the remaining 860 patients 844 (98.1%) had a complete 1-year follow-up. Patients were divided according to their age: Group I (50 to 59 years), Group II (60 to 69 years) and Group III (70 to 79 years). The prevalence of AF in the general population was taken from the Framingham Heart Study. Patients in groups I and II had a higher incidence of AF before the operation than the general population (1.5% versus 0.4% and 3.1% versus 1.6%, respectively, P <0.05) and also ...

American journal of critical care : an official publication, American Association of Critical-Care Nurses, 2003
Atrial fibrillation is the most common complication after cardiac surgery and a major cause of morbidity and increased cost of care. To examine the incidence, timing, symptoms, and risk factors for atrial fibrillation after cardiac surgery. A total of 302 patients were continuously monitored for atrial fibrillation with standard hardwire and telemetry devices during hospitalization after coronary artery bypass graft and/or valve surgery and with wearable cardiac event recorders for 2 weeks after discharge from the hospital. After discharge, patients recorded and transmitted their rhythm by telephone daily and whenever they had symptoms suggestive of atrial fibrillation. Of the 302 patients, 127 (42%) had atrial fibrillation; 41 had it after discharge, and for 10 it was their first episode. The first episode occurred at a mean of 2.9 days after surgery (SD, 3.1; range, day of surgery to 21 days after surgery). Although palpitations was the most common symptom (17%), most episodes of ...

Background: Postoperative atrial fibrillation (POAF) is a common and potentially morbid complication following cardiac surgery. It was reported to be associated with greater inhospital mortality; prolonged hospital stays. In addition, the long-term survival was worse in patients who developed POAF. Patients who develop POAF incur additional hospital treatment cost and 2-to-4-fold increased risk of major adverse cardiac events. Objective: To determine the possible predictors of POAF after coronary artery bypass surgery and its impact on outcome. Methods: Two hundred patients were enrolled; they were divided into 2 groups; Group I (n = 100 patients) developed POAF and group II (n = 100 patients) did not developed POAF. All patients were subjected to history, examination, ECG, echocardiography, laboratory investigation as CBC, coagulation profile, kidney function tests, liver enzymes and high sensitivity troponin and coronary angiography to assess severity of coronary artery disease by SYNTAX score.

Background This study was conducted to determine the effect of certain predictors on the incidence of postoperative atrial fibrillation (POAF) during ICU stay after coronary artery bypass graft (CABG) surgery. Results We enrolled 123 patients in this study. The mean age was 57.4 ± 8.7 years, and the mean left atrial diameter was 4.1 ± 0.52 cm with male preponderance (76.4%). The incidence of POAF following CABG was 33.3%. There was no statistically significant association between POAF and smoking (P = 0.123). However, POAF was significantly associated with higher CHA2DS2-VASc score (P = 0.002), valve replacement (P < 0.001), and inotropic support (P = 0.005). Moreover, patients with POAF had significantly higher mean age (P = 0.031) and left atrial (LA) diameter (P < 0.001). Logistic regression showed that LA diameter (P < 0.001), potassium level at 36 h (P = 0.016), and female gender (P = 0.001) were independent predictors of POAF. Conclusions We had several significant ep...
