Long-term outcomes and predictors of mortality in patients undergoing coronary artery bypass grafting: A 10-year follow-up study

Abstract: This retrospective study examines the long-term survival and mortality predictors in 1,032 patients who underwent coronary artery bypass grafting (CABG) between 2010 and 2013 at a tertiary care centre in South India. The primary objective was to assess the 1-, 3-, 5-, and 10-year survival rates and identify key factors influencing mortality. Findings revealed that CABG is associated with high long-term survival rates, with 1-year, 3-year, 5-year, and 10-year survival rates of 95%, 91%, 88%, and 85%, respectively. Key determinants of mortality included age, left ventricular ejection fraction (LVEF), left main coronary artery (LMCA) involvement, type of surgery, presence of regional wall motion abnormality (RWMA), and haemoglobin A1c (HbA1c) levels. This study underscores the importance of personalized patient management strategies to optimize outcomes following CABG.
