Triglyceride-Glucose Indices and Left Ventricular Speckle Tracking in Predicting Coronary Artery Disease Severity

"Derived indices included:~* Ty,G×B,M,I = TyG index × body mass index~* TyG×W,C = TyG index × waist circumference~* TyG×WH,tR = TyG index × waist-to-height ratio Quartile-based stratification was applied to each TyG-derived index."

Coronary Angiography and Gensini Scoring: All participants underwent standard diagnostic coronary angiography. CAD was categorized as one-, two-, or three-vessel disease based on the number of vessels with ≥50% stenosis. The severity of CAD was quantified using the Gensini score, which assigns a severity weight to each lesion depending on degree of stenosis and anatomical location. Final scores were calculated by summing weighted values across all coronary segments.
