Role of HbA1C & glycated albumin as predictors of cardiovascular outcome post-myocardial infarction in diabetic patients

Background: Diabetes mellitus significantly increases the risk of adverse cardiovascular outcomes following ST-elevation myocardial infarction (STEMI). Glycaemic markers like HbA1C and glycated albumin (GA) may serve as prognostic indicators, but their predictive validity in Indian diabetic populations remains underexplored. Thus, this study was conducted to evaluate the prognostic value of HbA1C and GA in predicting adverse cardiovascular outcomes post-MI in diabetic patients. Methods: A matched case-control study was conducted among 260 type II diabetic STEMI patients in a tertiary care hospital. Cases were those developing post-MI complications; age- and sex-matched controls who did not. Glycaemic markers and clinical risk factors were analyzed using conditional logistic regression and ROC analysis. Results: Raised HbA1C and GA levels were significantly associated with higher odds of post-MI complications (aOR: 5.55 and 10.9, respectively). GA showed superior diagnostic accuracy (AUC: 0.948) and specificity (57.6%) over HbA1C. Conclusion: GA is a promising biomarker for risk stratification in diabetic patients post-MI and may complement HbA1C in clinical practice.
