Model 1 = baseline risk model, including age, heart rate, SBP, Serum creatinine, LVEF; Model 2 = Model 1 + rSS; Model 3 = Model 1 + Tyg index; Model 4 = Model 2 + Tyg index.
MACEs major adverse cardiac events, SBP systolic blood pressure, LVEF left ventricular ejection fraction, NRI net-reclassification index, IDI integrated discrimination improvement, CI confidence interval
