Early outcomes of On Pump versus Off Pump CABG in patients with Left Ventricular Dysfunction

INTRODUCTION: There is little data available on the application of an on-pump technique for surgical revascularization in patients with significant left ventricular (LV) dysfunction. It is still debatable whether patients with severe left ventricular failure should have coronary artery bypass grafting (CABG) done on-pump or off-pump to restore blood flow. So, this study aims to assess the early clinical outcomes of patients undergoing surgical revascularization using either an on-pump or an off-pump approach in patients with an LVEF of ?35 %. AIMS & OBJECTIVES: The aim of the study was to assess the early clinical outcomes of patients undergoing surgical revascularization using either an on-pump or an off-pump approach in patients with an LVEF of ?35 %. MATERIAL & METHODS: This was a cross sectional study in which 180 patients undergoing CABG were enrolled. Nonprobability purposive sampling technique used to select the patients. RESULTS: The average age of the individuals in Group A was 54.86 ± 8.49, whereas in Group B it was 53.94 ± 9.68. In Group A, 67.8% of the individuals were male while in Group B, 64.4% were male. The comparison of mortality, pulmonary complications, neurological complications and renal complications was found insignificant with respective insignificant p-values being as 0.560, 0.351, 0.312 and 0.155. CONCLUSION: In this study both groups experienced comparable rates of mortality, neurologic, pulmonary, and renal complications so, it is challenging to determine whether off-pump or on-pump CABG can serve as a standard treatment for patients with significant left ventricular failure.
