Abstract

A descriptive study was conducted at the Department of Medicine and Cardiothoracic Surgery, Aga Khan University Hospital, Karachi, from May 27, 2019, to November 27, 2019, to determine the frequency of acute kidney injury in patients after coronary artery bypass grafting. A total of 174 patients who underwent coronary artery bypass graft surgery were enrolled in the study. Postoperatively, all patients were closely observed for acute kidney injury up to 48 hours post-surgery. The demographic characteristics of the participants revealed a mean age of 54.14±9.49 years, with 108 (62.1%) being males and 66 (37.9%) females. Out of the total participants, 25 (14.4%) experienced acute kidney injuries, while 149 (85.6%) did not show any signs of acute kidney injuries. The findings suggest that acute kidney injury is a common complication following isolated coronary artery bypass graft (CABG) surgery. This observation holds significant clinical importance, as it is associated with unfavourable postoperative outcomes, prolonged stays in the intensive care unit (ICU), and elevated fatality rates. These insights underscore the need for careful monitoring and management of renal function in patients undergoing CABG surgery to mitigate the impact of acute kidney injury on overall postoperative well-being.
