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

A cross sectional study that will be conducted in Cardiovascular Department of Tanta University in Egypt in the period from May to July 2025 . Two hundred patients diagnosed with coronary artery diseases were included in the study. Patients were considered to have confirmed coronary artery disease through angiographically proven CAD.
