Background: Obesity and its complications are global health concerns with rising interests, and in Bangladesh, the scenario is not different. This study was designed to analyze the effect of BMI on postoperative outcomes in patients who underwent Off-Pump Coronary Artery Bypass (OPCAB)graft surgery. Methods: This prospective observational study was conducted from September 2017 to August 2018 in the department of cardiac surgery, NICVD & 90 patients were divided into two groups. 43 patients in group A, with BMI ≥ 25 kg/m2 and 47 patients in group B, with BMI<25 kg/m2. Results: In between groups, homogenous distribution was noted in terms of age and sex. Pre-operative risk factors, such as hypertension, dyslipidemia, and sternal wound infection, harvest site infection along with post-operative AF, were significantly higher in group A in comparison to group B. Conclusion: Obese patients undergoing OPCAB surgery should undergo maximum care. Meticulous tissue handling during OPCAB surgery in obese patients is needed to avoid or minimize sternal, and harvest site wound infection.

Background:  Bilateral internal mammary artery (BIMA) use may improve long-term outcomes after coronary artery bypass grafting (CABG); however, the risk of infection is high.   Skeletonization of the internal mammary may decrease the risk of infection, especially in patients with diabetes. Our study aimed at evaluation of sternal healing in diabetic patients with different techniques of bilateral internal mammary artery harvesting. Methods: This prospective randomized study included 200 diabetic patients who underwent CABG using BIMA between 2017 and 2019. We divided patients into two groups; Group A had skeletonization of both internal mammary arteries, and Group B had pedicled left mammary and skeletonized right mammary. Patients were observed for three months, post-operatively for any sternal wound problems. Results: There was no significant difference regarding the baseline variables. Type I diabetes mellitus was present in 25% in group A (n= 24) and 13.64% in group B (n= 12) (p= 0.324). There was no difference in harvest time between groups (83 ±4 vs. 81 ±3 minutes in group A vs. B, respectively. P= 0.1). The mean number of grafts was 3± 0.5 in Group A and 3± 0.6 in Group B (p= 0.8). Postoperative drainage was 402.9 ± 174.1 ml in Group A vs. 387.2 ± 153.6 ml in Group B (p= 0.474). The duration of ICU stay did not differ significantly between groups (2± 0.7 in Group A vs. 2± 0.5 in Group B; p= 0.8). Deep sternal wound infection occurred in 4.17% in group A (n= 4) and 4.55% in group B (n= 4) (p= 0.705). Superficial wound infection occurred in eight patients in group A (8.33%) and eight patients in group B (9.1%) (p= 0.59). No patient had sternal dehiscence in group A vs. four patients in group B (4.55%) (p= 0.39). Conclusion: We did not find differences between bilateral mammary artery harvest with skeletonization of both arteries versus skeletonization of the right mammary only on sternal healing nor wound infection in diabetic patients undergoing CABG. A larger study is recommended.

Objective: The Neurological injury is an important complication after coronary artery bypass surgery (CABG). The incidence of neurocognitive impairment after cardiac surgery varies from 20% to 80%. In this study we tried to analyze this difference of neurologic dysfunction between On-pump CABG and Off-pump CABG (OPCAB).Methods:This is a case control study done in National Institute of Cardiovascular Disease (NICVD), Dhaka during the period of July 2012 to June 2014. Sixty Patients with Ischemic heart disease were the study population. Group- A includes 30 patients underwent on pump CABG, Group-B 30 patients underwent OPCAB. All the patients of both the groups were followed up to 2 month’s postoperatively to find out any neurological and neurocognitive dysfunctionby observing motor function, sensory function,Mini Mantel state (MMS) Examination, orientation, memory, attention and calculation, recall and language test.Results: Neurocognitive dysfunction in the early postoperative period is significantly different among the groups.Neurocognitive dysfunction was more in Group A in comparison to Group B, On 3rd and 8th POD the MINI Mental Scores were found to be significantly lower in On-pump group than those in Off-pump group (22.0 ± 5.28 vs. 25.67 ± 3.34, p = 0.002 and 25.93 ± 3.11 vs. 26.63 ± 2.50, p = 0.023 respectively).This neurocognitive dysfunction gradually improved by the end of two month postoperative period. Only 6.66% patient in Group-A was found neurocognitically dysfunctional and was referred to neurophysician for further treatment. In case of OPCAB Group, no patient suffered fromneuorocognitive dysfunction.Conclusion: This study has convincingly shown cardio-pulmonary bypass (CPB) has had detrimental effect on neurocognitive function in patients who underwent CABG.Cardiovasc. j. 2018; 10(2): 186-193

Abstract Background Myocardial structural damage may occur during coronary artery bypass grafting (CABG) surgery and is identified by the significant release of cardiac biomarkers. However, the evidence of these structural myocardial changes after CABG by current imaging methods remains unknown. To evaluate myocardial structure, we used the T1 mapping of cardiac magnetic resonance (CMR) before and after on-pump and off-pump CABG. Methods Patients with multivessel coronary artery disease and preserved ventricular function were included and underwent on or off-pump CABG. CMR and T1 mapping were performed using the MOLLI technique (modified Look-Locker inversion-recovery). Values of native T1 and extracellular volume fraction (ECV) were compared before and after on and off-pump procedures. Results Of 110 eligible patients, 34 were excluded due to the presence of new late enhancement or edema. Of 76 patients remained, 32 (42%) underwent on-pump (Group A) and 44 (58%) off-pump CABG (Group B). All baseline characteristics were similar between groups, besides the Syntax Score that was higher in Group A (25 × 21, p=0.002). For group A, native T1 before and after procedures was 1013 ms (998–1043) and 1004 ms (793–1048), p=0.19, and ECV was 26.4 (23.9–27.6) and 31.2 (27.6–33.9), p<0.001. For group B, native T1 before and after procedures was 1015 ms (970–1044) and 992 ms (867–1051), p=0.003, and ECV 27.5 (25.3–29.9) and 30.3 (26.5–34.3), p=0.02. The comparison of native T1 difference before and after procedures between groups A and B was not significant (Delta T1 −9.8 (−102 to 51.8) × −25.4 (−119 to 51,2), p=0.87. However, the difference of ECV between groups was statistically significant (ECV Delta 3.8 (2.2 to 7.1) × 1.3 (−1.1 to 4.9), p=0.039, respectively, for groups A and B. Figure 1 Conclusion In this sample, T1 mapping identified significant myocardial structural changes in both surgical revascularization procedures. Additionally, a marked myocardial injury generated by ECV changes were observed after on-pump CABG.

Objective The purpose of this randomized study was to evaluate the effect on graft patency by adding clopidogrel to aspirin in off-pump coronary artery bypass (OPCAB) grafting and the possible side effects of such therapy. Methods Twenty patients who underwent standard OPCAB through median sternotomy were randomized immediately after surgery in two groups. Patients in group A (n = 10) received 100 mg of aspirin starting preoperatively, continuing indefinitely. Patients in group B received 100 mg of aspirin and, in addition, 75 mg of clopidogrel starting immediately after the operation and for 3 months. Postoperative bleeding and other perioperative parameters were compared. Angiography was repeated 3 months after surgery to determine the patency and quality of grafts. Results Preoperative risk factors were similar in the two groups. There was no significant difference in average number of distal anastomosis (P = 0.572), operation time (P = 0.686), postoperative bleeding (P = 0.256), ventilation time (P = 0.635), and intensive care unit stay (P = 0.065). Length of stay was shorter in group B (P = 0.024). There was no postoperative complication in either groups. Eight of 27 grafts in group A and 2 of 29 grafts in group B (P = 0.037) were occluded at the time of control angiography. Conclusions Early administration of a combined regimen of clopidogrel and aspirin after OPCAB grafting is not associated with increased postoperative bleeding or other major complications. Despite the small number of patients in this study and small number of examined grafts, the results suggest that the addition of clopidogrel may increase graft patency after OPCAB grafting.

Abstract Background and Aims There are few clinical data on Adalimumab (ADA) biosimilars in inflammatory bowel disease. Methods SPOSAB ABP 501 is a multicenter, observational, prospective study performed among the cohort of the Sicilian Network for Inflammatory Bowel Disease. All consecutive patients treated with ADA biosimilar ABP 501 from the introduction of the drug in Sicily (February 2019) to February 2020 (12 months) were enrolled to assess its safety and effectiveness. Patients were divided into 3 groups: group A, naïve to ADA and naïve to anti-TNFs; group B, naïve to ADA, previously exposed to anti-TNFs; group C: switched from ADA originator to ABP 501. Results 559 patients (median age 39 years; CD 88.0%, UC 12.0%) were included, with a follow-up time of 403.4 patient-years. Thirty-six SAEs occurred in 36 patients [(6.4% - incidence rate (IR): 8.9 per 100 person-years (PY)]. The IR of SAEs was higher among patients in group A compared with group C (17.4 vs. 4.8 per 100 PY; IR ratio=3.61; p&lt;0.001) and among patients in group B compared with group C (16.4 vs. 4.8 per 100 PY; IR ratio=3.42; p=0.041). Among ADA-naïve patients (group A+B), 188 (85.8%) had a clinical response after 12 weeks, including 165 (75.3%) who achieved steroid-free remission. Higher treatment persistence estimates were reported for patients in group C compared with group A and B (log-rank p&lt;0.001). Conclusions Safety and effectiveness of ABP 501 seem to be overall similar to those reported for ADA originator. Switching from originator to ABP 501 was safe and effective.

Background: Atrial Fibrillation (AF) is common in early recovery period after cardio-thoracic surgery. There have been several pharmacological and nonpharmacological strategies suggested for prevention against AF after coronary artery bypass grafting. The purpose of this study was to evaluate the effect of oral amiodarone in the prevention of atrial fibrillation in patients who underwent off pump coronary artery bypass graft (OPCAB).Methods: This interventional study was conducted from February 2017 to January 2018 in the department of cardiac surgery, National Institute of Cardiovascular Disease (NICVD) Dhaka, Bangladesh. By purposive sampling a total of 100 patients having sinus rhythm who will undergo OPCAB were selected for the study. Among them 50 patients (Group-A) got amiodarone (600mg/day started 3 days prior to surgery) and 50 patients (Group-B) did not get amiodarone. Two (2) patients of group-A were excluded from the study due to conversion to on pump from off pump during operation. So, finally group A had 48 patients and group- B had 50 patients. Preoperative electrocardiography (ECG), serum electrolytes (e.g. potassium & magnesium), thyroid function test, liver function test and echocardiogram were done in all patients under study. Per-operative occurrence of AF was assessed on operation theatre monitor. Each patient was evaluated by continuous ECG up to 5th post-operative day (POD). Serum potassium & magnesium were measured in every alternative day up to 5th POD. ECG with long lead tracing was done for all patients on the day of hospital discharge & was recorded. Data were analyzed by SPSS 24.0 (Statistical Package for the Social Sciences) and tested by student T-test and Chi-square test. P < 0.05 was considered significant.Results: Pre-operative baseline characteristics were similar in both groups. Per-operative and postoperative AF occurred more frequently in group B than group A. Those were 10(20.83%) and 32(64.0%) peroperative, 9(18.75%) and 31(36.0%) immediate postoperative period respectively in group A and group B. The result was statistically significant (P value<.05). Post-operative amiodarone used in all patients who developed AF irrespective of groups. This also decreased AF significantly. There were statistically no significant difference found in postoperative serum electrolytes and use of inotropes, anti-arrhythmic drugs. All patients recovered well.Conclusion: This study concluded that preoperative oral administration of amiodarone can prevent the occurrence of atrial fibrillation in patients undergone Off Pump Coronary Artery Bypass (OPCAB).Bangladesh Heart Journal 2018; 33(1) : 67-73

The Impact

Objectives: To evaluate the impact of skeletonized bilateral or single internal thoracic artery (ITA) grafting on the risk of deep sternal wound infection (DSWI) in diabetic patients undergoing off-pump coronary artery bypass grafting (OPCAB). Materials and Methods: A total of 803 diabetic patients undergoing OPCAB surgery from January 2010 to December 2014 were enrolled into this study and assigned to the pSITA group (patients undergoing pedicled single ITA grafting, n = 362), the sSITA group (skeletonized single ITA grafting, n = 295), or the sBITA group (skeletonized bilateral ITA grafting, n = 146). The primary end point was the diagnosis of a DSWI. Results: Eighteen patients developed postoperative DSWI, with an incidence of 2.2%. Patients in the sSITA group had a significantly lower incidence of DSWI than those in the pSITA group (1.0 vs. 3.6%, p = 0.0408). In multivariate logistic regression analysis, the risk of DSWI in the sSITA group was 0.41 times that in the pSITA group. Conclusions: sSITA grafting lowered the risk of DSWI in diabetic patients undergoing OPCAB surgery compared to pSITA grafting. Multicenter clinical trials involving larger sample sizes are needed to determine the merit of pSITA grafting in reducing the risk of DSWI following OPCAB surgery.
