Despite advances in prevention and treatment, coronary artery disease (CAD) remains a major cause of death globally. Glycated haemoglobin (HbA1c) and body mass index (BMI) are known risk factors for CAD. This study aimed to investigate the relationship between the metabolic coronary risk index (MCRI) and the severity of CAD, measured by the SYNTAX score (SS), in patients with acute coronary syndrome (ACS) who underwent coronary angiography (CAG). A total of 214 patients were included, with a mean age of 59.29 ± 11.93 years, and 25.7% were female. Regression analysis showed that MCRI independently predicted CAD severity. MCRI differentiated moderate and high SS from low SS with 70% sensitivity and 50% specificity at a cutoff value of 158.9. The study concluded that MCRI is a significant predictor of CAD severity in ACS patients.
