Background: Coronary artery bypass grafting is a commonly executed surgical procedure for individuals with coronary artery disease (CAD). Coronary artery disease (CAD) involves the constriction of the coronary arteries. which are responsible for delivering oxygen and nutrients to the heart muscle. the condition arises from the accumulation of fatty substance within the artery walls. This accumulation restricts the interior of the arteries. reducing the flow of oxygen rich blood to the heart muscles. The procedure can be carried out using two methods. off-pump (CABG), which is done without cardiopulmonary bypass on a heart that is still beating on-pump coronary artery bypass grafting (CABG). which involves cardiopulmonary bypass, on-pump (CABG) has been the conventional methods providing a motionless surgical field and allowing accurate anastomosis. The decision between these two methods has been a topic of continual discussion especially concerning their short-term results. Off-pump coronary artery bypass grafting (CABG)may be associated with increase hazard for short-term mortality as compared with on-pump coronary artery bypass grafting Aim: The Aim of the study is to analyze and compare the short-term outcomes in patients underwent on pump CABG to off pump CABG. Objectives: To analyze and evaluate the following data. ? ECG ? ECHO ? Heart Rate ? CBC ? Ejection fraction Methodology: The study was conducted in 40 patients underwent Coronary Artery Bypass Graft. The study was done to analyze and compare the outcome in patients underwent on-pump vs off- pump CABG. They were divided into two groups, group A (on-pump) and group B(off- pump) The data were collected from past history and medical reports, case sheets ECG, ECHO, Heart rate, CBC, Ejection fraction. Result: According to the study, 40 patients have been compared and analyzed on short term outcomes. the both groups, group A (on-pump) and group B (off pump), shows as off pump patients usually have a faster discharge from the hospital, but on-pump patients often have more durable long – term graft. Conclusion: This study was conducted to compare and analyze the short-term outcomes between on- pump vs off –pump in patients undergoing coronary artery bypass graft. According to the study, it is concluded that patients undergoing off-pump Coronary Artery Bypass Graft. patients usually have a faster discharge from hospital, but on- pump Coronary Artery Bypass Graft. Patients often have more durable long-term graft success.
