Abstract

Background: Postoperative hyperglycemia is a well-documented risk factor for complications following cardiac surgery, even in patients without a prior history of diabetes. This study aimed to assess the prevalence of postoperative hyperglycemia in non-diabetic patients undergoing cardiac surgery.  Methods: A total of 101 non-diabetic patients who underwent cardiac surgery were included in this observational study. Demographic, surgical, and glycemic data were collected and analyzed to identify patterns and potential risk factors associated with postoperative hyperglycemia. Results: Of the patients studied, 92.1% had normal preoperative glucose levels, yet 63.4% developed elevated or high glucose levels postoperatively. Patients who developed hyperglycemia were notably older (mean age 40.7 years) compared to those who maintained normal glucose levels (mean age 30.5 years), while body mass index (BMI) showed no significant difference between groups. CABG was the most frequently performed procedure (58.4%). A progressive increase in BMI and weight was observed across age groups. Conclusion: The findings indicate that postoperative hyperglycemia is common in non-diabetic cardiac surgery patients, with older age identified as a significant risk factor. These results highlight the importance of routine glucose monitoring and early management in non-diabetic individuals to reduce the risk of adverse outcomes. Further research is recommended to explore additional predictive factors and long-term effects of stress- induced hyperglycemia.
