Statistically significant variables with univariate analysis were enrolled in the multivariate model. Odds ratio (OR) for per 1 standard deviation increased in each continuous variable. N-terminal B-type natriuretic peptide (NT-proBNP) was natural logarithmically transformed to ln (NT-proBNP)
NA: not assessed, CI: confidence interval, BMI: body mass index, MI: myocardial infarction, PCI: percutaneous coronary intervention, CKD: chronic kidney disease, LVEF: left ventricular ejection fraction, TnI: Troponin I, eGFR: estimated glomerular filtration rate, hs-CRP: high-sensitivity C-reactive protein, SHR: stress hyperglycemia ratio
