Values are presented as median (IQR) for continuous variables and n (%) for categorical variables. Psychological disorders include clinically diagnosed or screening-confirmed depression, anxiety, or adjustment disorders occurring within 6 months post-percutaneous coronary intervention. P values were calculated using the χ² test for categorical variables and the Mann-Whitney U test for continuous variables. BMI: Body mass index; BP: Blood pressure; LVEF: Left ventricular ejection fraction; NT-proBNP: N-terminal pro-B-type natriuretic peptide; eGFR: Estimated glomerular filtration rate; LDL-C: Low-density lipoprotein cholesterol; HbA1c: Glycated hemoglobin; CK-MB: Creatine kinase-MB; NYHA: New York Heart Association; BUN: Blood urea nitrogen; AST: Aspartate aminotransferase; ALT: Alanine aminotransferase.
