Consensus evidence-based guidelines for management of hyperglycaemia in patients undergoing coronary artery bypass grafting in patients with diabetes in India

Abstract

Diabetes is associated with a significant risk of cardiovascular diseases (CVDs). Patients with diabetes are known to suffer from a disproportionately large burden of CVDs, in terms of higher risk, worse prognosis and more adverse outcomes. Acute coronary syndromes, including coronary artery disease, represent a large proportion of this burden and conventionally coronary artery bypass grafting (CABG) has been the mainstay of facilitating reperfusion in patients with diabetes. However, hyperglycaemia is an important factor which affects the outcomes of CABG and shows a grave impact on patients' well-being. Thus, it is important to appropriately manage hyperglycaemia in the peri-and intra-operative periods to assure the best possible outcomes in patients with diabetes. There is scant evidence to show that oral antidiabetic drugs (OADs) or non-insulin based therapies show considerable benefit in patients undergoing CABG. Even with the use of insulin-based therapies, appropriate glycaemic targets, accurately designed algorithm to achieve such targets and specific recommendations to facilitate the appropriate use of such algorithm are important considerations. However, current international guidelines are either country-specific or fail to address context-specific needs in individual countries. In view of the growing incidence of cardiovascular diseases and diabetes in India, as a result of changing lifestyles, it is imperative upon clinicians to formulate India-specific guidelines for effective management of (CVDs). It is the endeavour of the current guideline to present recommendations based on a firm evidentiary foundation coupled with context-specific inputs from experts' consensus opinion. These recommendations represent an effort to address the urgent need for such an exercise both in the academic as well as the clinical realm.
