Note: AO: Aortic Diameter; IVS: Interventricular Septum; LVDd: Left Ventricular Diastolic Diamete; LVDs: Left Ventricular Systolic Diameter; SV: Stroke Volume; EF: Ejection Fraction; TC: Total Cholesterol; HDL: High-Density Lipoprotein; LDL: Low-Density Lipoprotein; CK: Creatine Kinase; CKMB: Creatine Kinase Isoenzyme MB; BUN: Blood Urea Nitrogen; Cr: Creatinine; K: Potassium; MI: History of myocardial infarction; smoke: smoking history; Alcoholism: drinking history; Lesion: Number of coronary lesions; CI: Confidence Interval; OR: Odds Ratio; VIF: Variance Inflation Factor;
VIF values were calculated to assess multicollinearity among predictors retained in the final multivariate model. All VIF values were < 2, indicating no significant multicollinearity
