The constant was calculated via logistic regression by SPSS. A, mitral atrial systolic peak velocity; PCT, procalcitonin; CK-MB, creatine kinase-MB; H-FABP, heart-type fatty acid-binding protein; NT-proBNP, N-terminal pro-brain natriuretic peptide; HF, heart failure. b, regression coefficient; SE, standard error; Wald χ2, χ2 value of Wald statistic; OR, odds ratio; 95% CI, 95% confidence interval.
