Objective: Postoperative atrial fibrillation (POAF) is a common complication after cardiac surgery, and it remains a challenge for cardiac surgeons despite advances in medicine. A number of studies have been performed to examine various parameters to predict which patients will develop POAF. The present study was performed to investigate the roles of epicardial adipose tissue (EAT) volume and red blood cell distribution width (RDW) as predictors of POAF. Methods: The medical records of 350 patients undergoing coronary artery bypass grafting in one or more vessels at the Tertiary Cardiac Center, Cardiovascular Surgery Department, Mevlana (Rumi) University Private Hospital (Konya, Turkey), were screened between December 2011 and May 2015. The study population consisted of 149 patients fulfilling the inclusion criteria and undergoing a preoperative evaluation by computed chest tomography. All patient demographics and laboratory parameters were obtained from medical records. Results: Age, postoperative RDW, and tomography variables, including the left atrial (LA) volume, LA diameters, and EAT volume, were significantly higher while the hemoglobin level and hematocrit were significantly lower in patients developing atrial fibrillation after cardiopulmonary bypass. A logistic multivariate regression analysis was performed on age, postoperative RDW, and tomography variables, including LA volume, LA diameters and EAT volume. Only age (OR 1.0731, 95% CI 1.012-1.138; p = 0.018) was an independent predictor of the development of POAF. Conclusions: Although the EAT volume was high in patients developing atrial fibrillation after surgery, age was the only significant predictor of POAF on multivariate analysis. Additional studies regarding the predictive roles of epicardial fat and RDW in POAF are needed.

Introduction:There are several studies about the mortality of the CABG patients with the importance of the inflammation. The aim of our study was to evaluate the relationship between RDW and in-hospital mortality in CABG patients.Methods: A total of 346 patients undergoing coronary artery bypass grafting operation were analyzed for our study. Preoperative 2 ml blood sample was put into tubes for evaluation all patients complete blood count. All patients underwent same anesthesia protocol. The type of CABG procedure (off-pump vs on-pump CABG) was determined by the operation team. Results:There was ten patients died in-hospital period (Group 1) and three hundred and thirty-six patients lived during in hospital follow up (Group 2). WBC (10.8 ± 5.2 x 103 vs 7.9 ± 2.2 x 103 p: 0.04), Neutrophil (7.3 ± 3 x 103 vs 5.1 ± 2 x 103 p: 0.03), N/L Ratio (4.8 ± 2.6 % vs 2.7 ± 1.6 % p: 0.01) and RDW (14.8 ± 1.6 % vs 13.9 ± 6.6 %, p: 0.002) values were higher in group 1 than group 2, respectively. A logistic multivariate regression analysis showed that only RDW (OR 1.860, 95% CI 1.105-3.132; p: 0.02) was an independent predictor of the development of mortality in-hospital period in CABG patients. Conclusion:To our knowledge, this is the first report of an association between RDW and the development postoperative mortality in CABG patients.

Thoracic periaortic fat tissue volume may be considered a useful new parameter for predicting major adverse cardiovascular events.

Angiographic detection of critical stenosis of left main coronary artery (LMCA) dramatically alters the patient's treatment approach. Therefore it should be examined further. This image of the LMCA may be due to sharp angulation, catheter-induced spasm or the relative stenosis due to ectatic LMCA. Operators can be avoided unnecessary revascularization procedures with further investigation. We report the image of angiographically severe stenosis of the LMCA due to a sharp angulation.
