  1. TyG, triglyceride-glucose; NRI, net reclassification improvement; IDI, integrated discrimination improvement;
  2. The basic model included: sex, age, body mass index, low-density lipoprotein cholesterol, systolic blood pressure, diastolic blood pressure, smoking status, drinking status, aortic stenosis severity, pulmonary arterial hypertension, left ventricular ejection fraction, bicuspid aortic valve, aortic valve replacement, diabetes mellitus, CHD, antiplatelets, and statins use
