Different cardiac functions	Wald test value	OR	Degree of freedom	SE	P-value
Cardiac function in class III and above	5.288	0.949	0.937	2.014	0.011
Increased NT-proBNP	10.653	2.620	0.964	0.057	0.025
Increased MMP-9	6.215	1.363	0.311	0.153	0.047
Decreased LVEF	6.625	1.669	−0.512	0.199	0.010

OR, odds ratio; SE, standard error; NT-proBNP, N-terminal pro-brain natriuretic peptide; MMP-9, matrix metalloproteinase-9; LVEF, left ventricular ejection fraction.
