Abstract
BACKGROUND Left main coronary artery (LMCA) supplies more than 80% of the left ventricle, and significant disease of this artery carries a high mortality unless intervened surgically. However, the influence of coronary artery bypass grafting (CABG) surgery on patients with LMCA disease on morbidity intensive care unit (ICU) outcomes needs to be explored. However, the impact of CABG surgery on the morbidity of the ICU population with LMCA disease is worth exploring.
AIM To determine whether LMCA disease is a definitive risk factor of prolonged ICU stay as a primary outcome and early morbidity within the ICU stay as secondary outcome.
METHODS Retrospective descriptive study with purposive sampling analyzing 399 patients who underwent isolated urgent or elective CABG. Patients were divided into 2 groups; those with LMCA disease as group 1 (75 patients) and those without LMCA disease as group 2 (324 patients). We correlated ICU outcome parameters including ICU length of stay, post-operative atrial fibrillation, acute kidney injury, re-exploration, perioperative myocardial infarction, post-operative bleeding in both groups.
RESULTS Patients with LMCA disease had a significantly higher prevalence of diabetes (43.3% vs 29%, P = 0.001). However, we did not find a statistically significant difference with regards to ICU stay, or other morbidity and mortality outcome measures.
CONCLUSION Post-operative performance of Patients with LMCA disease who underwent CABG were comparable to those without LMCA involvement. Diabetes was more prevalent in patients with LMCA disease. These findings may help in guiding decision making for future practice and stratifying the patients’ care.

Abstract
Objective: To evaluate the clinical safety of left internal mammary artery (LIMA) harvesting in hemodynamically unstable patients after establishing cardiopulmonary bypass (CPB) in isolated coronary artery bypass graft (CABG) surgery. Methods: The prospective observational study was conducted at Chaudhry Pervaiz Elahi Institute of Cardiology, Multan, Pakistan, from December 2016 to August 2018. All patients undergoing isolated CABG surgery in which LIMA conduit was harvested after establishing cardiopulmonary bypass because of hemodynamic instability at induction of anaesthesia or during surgery were included in the study. Preoperative, operative and postoperative characteristics of the patients were recorded. Data was analyzed using SPSS 19. Results: In Forty nine patients including 39 male and 10 female, early CPB had to be established because of hemodynamic instability and afterwards LIMA was harvested. Out of 49, 30 patients presented with CCS class III angina. 37 (75.5%) patients were scheduled on elective coronary surgery waiting list. There were 39 (79.59%) patients who weaned off bypass on mild inotropic support and 4 (8.16%) patients needed IABP support. All patients had multi-vessel coronary artery disease. Mean number of grafts were 3.428±0.577, CPB time was 110.59±25.594 and hospital stay was 5.367±1.424. Conclusions: The study showed that LIMA can be safely harvested in unstable patients after establishing extracorporeal circulation and by using this operative strategy in patients who need urgent or emergent surgical coronary revascularization LIMA can be safely used as a conduit.

Abstract
Background & Objective: Recent meta-analysis reports have called for more randomized trials to evaluate the effectiveness of GIK solution in patients of cardiac surgery. So this study was conducted to evaluate the effectiveness of Glucose-insulin-potassium (GIK) solutions in non-diabetic patients undergoing coronary artery bypass grafting. Methods: A total number of one hundred and sixty (160) patients were randomized into two equal groups; GIK Group and non-GIK group. In GIK group, 5% dextrose containing 70 IU/L regular insulin and 70 meq/L of potassium was administered. The infusion was started at a rate of 30 ml/hour after induction of anesthesia and before the start of cardiopulmonary bypass. The infusion was started again after removal of aortic cross clamp and was continued for six hours after the operation. Results: In early post-operative period, peak CKMB levels were high in non-GIK group 48.50±19.79 IU/L versus 33.40±14.69 IU/L in GIK group (p-value <0.001). There was no statistically significant difference in requirements of inotropic support between the groups. The mean duration of inotropic support in GIK group was only 5.50±6.88 hours in GIK group and 8.64±7.74 hours in non-GIK group (p-value 0.008). Mean ventilation time in GIK group was 5.06±2.39 hours versus 6.55±3.58 hours in non-GIK group (p-value 0.002). Similarly, ICU stay period was also shorter in GIK group (p-value 0.01). We did not found any detrimental effect of GIK infusion on non-cardiac complications e.g. renal, pulmonary and neurologic complications. Conclusion: Glucose-insulin-potassium (GIK) infusion has a beneficial role in myocardial protection and is associated with better post-operative outcomes without increasing the risk of non-cardiac complications.
