Predicting the presence and severity of coronary artery disease using surrogate markers of insulin resistance: A cross-sectional study.
Background: The triglyceride-to-high-density lipoprotein cholesterol (TG/HDL-C) ratio, Metabolic Score for Insulin Resistance (METS-IR), triglyceride-glucose (TyG) index, and triglyceride-glucose body mass index (TyG-BMI) have been associated with the occurrence and severity of coronary artery disease (CAD), although evidence remains limited.
Methods: A total of 1,017 patients undergoing coronary angiography for the first time were included. Insulin resistance (IR) indices were calculated based on patients' laboratory data. Significant CAD was defined as more than 50% stenosis observed in coronary angiography1.
Results: A positive correlation was found between CAD and the TyG index (ρ = 0.083, p = 0.008). Patients with CAD had a significantly elevated TyG index (9.02 ± 0.62) compared to those with single-vessel disease (SVD) (8.87 ± 0.59) (p = 0.012). A strong association was observed between CAD and the TG/HDL-C ratio (ρ = 0.114, p < 0.001). Patients with multi-vessel disease exhibited a considerably higher index (4.47 ± 2.46) compared to those with SVD (3.77 ± 2.45) (p = 0.003). The TyG index cut-off was 9.22 (27.5% sensitivity, 79.3% specificity, 82.2% positive predictive value (PPV), and 23.89% negative predictive value (NPV)), while the TG/HDL-C ratio cut-off was 3.6 (44% sensitivity, 65.2% specificity, 81.5% PPV, and 25.5% NPV).
Conclusion: Our findings indicate that the TG/HDL-C ratio, with a cut-off point of 3.6, and the TyG index, with a threshold of 9.22, are associated with the presence of CAD. (ClinicalTrials.gov registration number: NCT06237244).
