| Summary: | Objective: This study was designed to evaluate the impacts of high preoperative HbA1c levels and ABO and Rhesus D antigen (RhD) blood types on the risk of postoperative cardiac morbidity in morbidly obese patients who underwent sleeve gastrectomy.
Materials and Methods: In this retrospective study, 364 morbidly obese patients who underwent elective laparoscopic sleeve gastrectomy operation were included. Data regarding patients' demographics, preoperative HbA1c levels (low: 4–6%, high: >6%), ABO/RhD blood types, cardiac complaints within the first postoperative week and serum cardiac troponin levels (ng/mL) in patients with postoperative cardiac complaints were recorded.
Results: The findings showed that HbA1c levels were >6.0% in 38.2% of the patients, blood type A (45.9%) was the most prevalent blood type, and postoperative cardiac symptoms were evident in 16.5% of patients. Patients with high and low HbA1c levels were similar concerning ABO/RhD blood type or rate of postoperative cardiac complaints. In patients with postoperative cardiac complaints, a significant positive weak correlation was noted with high troponin levels and high preoperative HbA1c levels (r=0.215, p=0.022).
Conclusion: In conclusion, these findings of a retrospective cohort of morbidly obese patients who underwent sleeve gastrectomy revealed a significant positive weak correlation between high preoperative HbA1c levels and cardiac troponin levels in patients with postoperative cardiac complaints, while ABO/RhD blood type was not associated with preoperative HbA1c levels or the likelihood of postoperative cardiac complaints.
