Comparison of mortality in Off Pump Versus On Pump CABG in patients with significant LMS

INTRODUCTION: At our institute, we frequently conduct both on pump and off-pump coronary artery bypass surgery (CABG). CABG performed with cardiopulmonary bypass (on-pump surgery) is a treatment that is both safe and successful. In case of on-pump CABG, it is important to note that it is associated with a notable risk of surgical complications. Despite, off-pump CABG has been recommended as a method to reduce surgical complications. So, we designed this study to compare post-operative mortality rates for off-pump versus on-pump coronary artery bypass grafting in patients with severe LMS disease AIMS & OBJECTIVES: To compare post-operative mortality rates for off-pump versus on-pump coronary artery bypass grafting in patients with severe LMS disease. MATERIAL & METHODS: This was a cross sectional study in which 200 patients undergoing CABG were enrolled. Nonprobability purposive sampling technique used to select the patients. Patients were divided into two groups 100 patients in each group. RESULTS: In this study the average age of the cases in Group A was 54.40 ± 8.60 while in Group B 54.20 ± 9.78. There were 68% males and 32% females found in Group A while 63% male and 37% females found in Group B. There were 44% diabetic, 65% hypertensive and 32% smokers found in Group A while 51% diabetic, 61% hypertensive and 28% smokers were found in Group B. The comparison of mortality was found significant (6% vs 1%) with p-value 0.05. CONCLUSION: Off pump surgery has been accepted in the management of LMS illness despite reasonable apprehensions and disagreements, as it results in a lower death rate than on pump CABG.
