Table 3 Relationship of NYHA functional class with other non-invasive CHF diagnostic markers, at enrollment.

CHF marker	Spearman’s r	P-value*
LVEF	−0.550
LAD	0.423
LVEDD	0.157	0.147
LVEDDI	0.254
LVM	0.082	0.450
LVMI	0.209	0.052
NT-proBNP	0.398
6MWD	−0.186	0.084
^* Statistically significant results are in bold. NYHA – New York Heart Association; CHF – chronic heart failure; r – correlation coefficient; P – level of significance; LVEF – left ventricular ejection fraction; LAD – left atrial dimension in the parasternal long axis view; LVEDD – left ventricular end-diastolic dimension; LVEDDI – LVDD index; LVM – left ventricular mass; LVMI – LVM index; NT-proBNP – amino-terminal pro-B-type natriuretic peptide; 6MWD – six-minute walk distance.
