Coronary artery disease is one of the commonest surgery demanding cardiovascular diseases. Coronary artery bypass graft surgery is practiced all over the world for the treatment of coronary artery disease. Systemic trauma during the surgery is associated with a wide range of complications, some of which are fatal. Preoperative risk factors such as age, previous illness and obesity are common predictors of these adverse events. Advances in therapeutic medicine have allowed timely treatment of these adverse events and co-morbidities. This review summarizes some of the most occurring complications associated with coronary artery bypass graft and corresponding treatment options.

Background The SYNTAX score is a helpful tool for determining the optimal myocardial revascularization strategy in complex coronary artery disease. The aim of this study was to assess whether the SYNTAX score predicts postoperative mortality in patients undergoing coronary artery bypass grafting. Methods The study included 1100 consecutive patients referred for coronary artery bypass graft surgery over a 4-year period. Angiographic data were interpreted by both experienced intervention cardiologists and cardiac surgeons. The patients were divided into three groups based on SYNTAX score tertiles: low ≤22 ( n =  560), intermediate 23–32 ( n =  360), and high ≥33 ( n =  180). Results Compared to patients with a low SYNTAX score, those with intermediate and high scores were significantly older ( p <  0.001), had a lower left ventricular ejection fraction ( p <  0.001), higher pulmonary artery pressure ( p <  0.001), and higher incidences of acute coronary syndrome and left main coronary artery disease. A significantly higher EuroSCORE ( p =  0.003) was also observed in patients with a higher SYNTAX score. Patients with intermediate and high SYNTAX scores had higher 5-year mortality rates (18.6% and 19.5%, respectively) than patients with low SYNTAX scores (9.5%, p <  0.05). In multivariate analysis, SYNTAX score was not an independent predictor of late mortality. Conclusion Although SYNTAX score is not independently predictive of late mortality in patients with complex coronary artery disease undergoing myocardial revascularization surgery, patients with lower SYNTAX scores had a lower mortality rate after coronary artery bypass graft surgery.

Background:The most common cardiac arrhythmia that happens after on-pump Coronary Artery Bypass Graft (CABG) surgery is Atrial Fibrillation (AF). It is combined with several postoperative complications such as increased incidence of stroke, increased hospital stay and increased costs.Objectives:The aim of this study was to look for safe, effective, reliable and well tolerated tools for the prevention of atrial fibrillation after on pump coronary artery bypass surgery.Patients and Methods:The study enclosed 176 patients (the age ranges from 40 to 79 years) and scheduled for elective on-pump CABG operations without concomitant procedures. The patients were selected randomly into two equal groups. Group (A) in which bisoprolol was used to prevent atrial fibrillation after surgery. Group (B) in which bisoprolol and hydrocortisone were used for prevention of atrial fibrillation after surgery. For each patient, the following data were collected: gender, preoperative diseases, cardiopulmonary bypass time, intraoperative cross clamp time, Left internal mammary Artery usage, incidence of postoperative atrial fibrillation, death, myocardial infarction chest infection and C-reactive protein amount in plasma.Results:There was a statistically significant decrease in the occurrence of atrial fibrillation in group (B) when compared to corresponding values in group (A). Also, group (B) showed a statistically significant decrease in length of hospital stay in comparison to group (A). C-reactive protein concentrations on the 1stand 2ndpostoperative days were lower significantly in group (B) than in group (A). There were no statistically significant differences between both groups regarding gender, preoperative diseases, cardiorespiratory bypass time, intraoperative cross clamp time, Left internal mammary artery usage, death, myocardial infarction and chest infection.Conclusion:This study demonstrated that using bisoprolol and hydrocortisone combination showed greater benefit than the use of bisoprolol only for prevention of postoperative AF after on-pump coronary artery bypass graft surgery.

Introduction: microRNAs (miRNAs) are highly conserved, noncoding RNA molecules that regulate gene expression on the post-transcriptional level. Some evidence indicates that microRNAs dysfunction plays a crucial role in human disease development. The role of microRNAs in cardiac growth, hypertrophy, heart failure, cardiovascular complications in diabetes and many other hearth conditions are demonstrated. In this study we aimed to evaluate the expression of six microRNAs (mir-100, mir-126, mir-127, mir-133a, mir-133b and mir-145) that have been shown to overexpress in aortic and carotid plaques. Methods: Thirty Coronary Artery Disease patients who underwent elective coronary artery bypass graft surgery were enrolled in the study. The expression patterns of six miRNAs (mir-100, mir-126, mir-127, mir-133a, mir-133b, and mir-145) were examined in 30 patients of whom we obtained aorta and saphenous vein samples. Results: In three miRNAs, mir-100, mir-127 and mir-133b, we did not obtain expression data from real-time experiments. We found that the expression level of mir-126, mir-133a and mir145 were lower in aorta in comparison with saphenous vein. Mir-126 was highly expressed in saphenous vein samples (13.8±1.1) when compared with aorta samples (20.2±1.1), although mir133a was highly expressed in saphenous vein samples (16.1±0.5) when compared with the aorta (17.9±1.5). Expression of mir-145 saphenous vein samples was also dramatically higher than aorta (7.2±0.5 versus 10.8±0.6) that was statistically significant (P<0.05). Conclusion: Understanding the role of miRNAs in cardiovascular physiology and diseases might suggest miRNA- based therapeutic methods in the management of coronary artery disease.
