Hypothesis

A substantial number of patients with dysglycemia can be identified at the time of cardiothoracic surgery despite having no apparent history of diabetes.

Conclusion

There is a high prevalence of undiagnosed dysglycemia among patients undergoing CABG who have no known history of diabetes.

Supporting Evidence

40% of patients had a known history of diabetes.
32.9% of patients with no known diabetes had normal HbA1c levels.
56.5% of patients were at increased risk for diabetes.
10.6% of patients were classified as diabetic based on HbA1c levels.
High HbA1c was associated with severe coronary artery disease.

Takeaway

Many people having heart surgery might have high blood sugar levels even if they didn't know they had diabetes. Checking for this can help doctors take better care of them.
