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).
