Literature Search:
A comprehensive literature search was done on PubMed, SCOPUS, Embase,
Cochrane database, google scholar and Ovid to identify the articles that
discussed the HbA1c, glycated haemoglobin and its implications on
perioperative cardiac surgery outcomes. Key words used were ‘HbA1c’
‘Glycated haemoglobin’ ‘Cardiac Surgery’ ‘Haemoglobin A’ ‘HbA1c and
outcomes’ ‘Diabetes’ ‘Diabetic correlation’. The search terms were used
as key words and in combination as MeSH terms to maximize the output
from literature findings. A staged literature search was done, whereby a
separate literature search was performed for each section within this
article and all the relevant studies were identified and summarized
separately. If a paper is reporting on many aspects of the practice of
HbA1C, then the results have been shared between different parts of this
review. The relevant articles are cited and referenced within each
section separately. No limits were placed on publication time or
language of the article.
