Prevalence of Hyperglycemia in Non-Diabetic Patients after CABG Surgery in the Cardiac ICU at Tertiary Care Hospitals in Peshawar

Abstract

Background: CABG, or coronary artery bypass graft surgery is recognized intervention for patient with severe coronary artery diseases. While restoring cardiac blood flow is the primary objective of CABG while improve clinical outcomes, emerging evidence suggests that postoperative hyperglycemia can significantly impact recovery and long-term health outcomes. Traditionally, hyperglycemia has been closely associated with diabetes mellitus, but recent studies indicate that even non-diabetic patients may experience elevated blood glucose levels following CABG surgery, raising concerns about its prevalence and implications. The aim of this research is to find out the prevalence of hyperglycemia in non-diabetic patient following CABG surgery. Methods: A cross sectional, descriptive study was conducted, 139 sample were collected through questionnaire. Further question were asked by the patient or according to his ICU charge sheet and then was noted in the questionnaire for research purpose. Results: Following CABG surgery, 67 patients with hyperglycemia and 72 patients without it were involved in this study. Multiple variate logistic study showed that patients with hyperglycemia were probably men, had a higher BMI, and were more probably ischemic and hypertensive heart diseases, myocardial infraction blood glucose level above 180mg/dl, pain after surgery which elevates BG and low body temperature, associated with post-operative hyperglycemia in non-diabetic  patient. Conclusion: Preoperative non diabetic patient’s characteristics are associated with hyperglycemia after cardiac surgery.
