Glycated Haemoglobin Levels and Its Effect on Outcomes in Cardiac Surgery

Daniyal Matin Ansari et al. Braz J Cardiovasc Surg. .

Abstract

There remains a significant paucity of information evaluating the effect of glycated HbA1c levels and its theorized effect on mortality and morbidity rates following cardiac surgery. Diabetes is a very common comorbidity in patients undergoing open heart surgery, as there is a shift in patient characteristics and greater risk. Currently, there is no clear consensus that an increase in HbA1c level is associated with increased perioperative mortality rate. However, the reported literature is more commonly able to demonstrate that elevated HbA1c levels is associated with increased rates of wound infection, cardiovascular events and renal failure, and thus, higher post-operative morbidities. This review aims to examine and synthesis the evidence behind each of the morbidities and mortalities associated with open heart surgery and the impact of high HbA1c on the reported outcomes.

Keywords: Cardiac Surgical Procedures; Cardiovascular Diseases; Comorbidity; Diabetes Mellitus; Glycated Hemoglobin A; Morbidity; Renal Insufficiency; Wound Infection.
