Pre-operative anaemia-does it influence post-operative outcomes after isolated coronary artery bypass grafting?

Introduction: Preoperative anaemia is prevalent in a number of patients undergoing coronary artery bypass grafting. Studies provide conflicting results due to several reasons including variation in the threshold of haematocrit used to define anaemia. We aimed to assess the independent effect of preoperative anaemia on outcomes in patients undergoing off pump coronary artery bypass grafting (OPCAB).

Machine learning algorithms for population-specific risk score in coronary artery bypass grafting.

Background: The aim of this study was to develop a new risk prediction score (NH Score) for patients undergoing coronary artery bypass grafting (CABG) specific to the Indian population and compare it to the Society of Thoracic Surgeon (STS) Score and the EuroSCORE II.

Method: The baseline features of adult patients who underwent CABG between the years 2015 and 2021 ( = 6703) were taken and split into training data (2015-2020;  = 5561) and validation data (2020-2021;  = 1142). The CatBoost algorithm was trained to predict risk scores (NH score), and the performance was tested on the validation set by Precision-Recall Curve and F1 Score.

Effect of preoperative statins on respiratory complications after coronary artery bypass grafting.

Objectives: Limited data exist on the effect of preoperative statin therapy on postoperative respiratory complications. Machine learning algorithms (MLA) can process large, heterogenous data, and have immensely improved the ability for risk prediction. In this study, we sought to examine the role of preoperative statins on respiratory complications in patients undergoing coronary artery bypass grafting (CABG) using MLA.

Comparison of European System for Cardiac Operative Risk Evaluation (EuroSCORE) and the Society of Thoracic Surgeons(STS) score for risk prediction in Indian patients undergoing coronary artery bypass grafting.

Background: For risk stratifying patients undergoing coronary artery bypass graft (CABG), the Society of Thoracic Surgeons (STS) risk score and the European System for Cardiac Operative Risk Evaluation (EuroSCORE) are currently used. However, the superiority of one over the other in the context of Indian patients has not been assessed. The aim of this study was to compare these 2 scoring systems in Indian patients undergoing CABG.

Uptake and impact of vaccination against COVID-19 among healthcare workers-evidence from a multicentre study.

To assess vaccination among healthcare workers, 14837 healthcare workers across 20 different hospitals were prospectively surveyed. The overall uptake of the vaccine was 13335(90%). Infection rate in vaccinated HCW was 710(6.

Atrial fibrillation - Can HbA1c levels really predict the risk?

Background: Diabetes is associated with higher mortality and worse post-operative outcomes in patients undergoing coronary artery bypass grafting and HbA1c levels have consistently been reported to be associated with adverse post-operative outcomes. However, the role of HbA1c still remains unclear with regards to the occurrence of atrial fibrillation.

Method: Data for the patients undergoing off-pump coronary artery bypass grafting was analysed in a retrospective fashion.

Preoperative Glycosylated Hemoglobin: A Risk Factor for Patients Undergoing Coronary Artery Bypass.

Background: The prevalence of diabetes in the population of patients presenting with coronary artery disease continues to rise. The aim of this study was to assess whether high Glycosylated hemoglobin (HbA1c) was associated with adverse outcomes in patients undergoing elective coronary artery bypass grafting.

Methods: A retrospective observational study on prospectively collected data in 4,678 patients undergoing elective, isolated coronary artery bypass graft procedures in a single institution over a 4-year period was conducted.
