Table 4 Relationship of 6MWD with other non-invasive CHF diagnostic markers.

CHF marker	Spearman’s r	P-value*
LVEF	0.059	0.586
LAD	−0.108	0.320
LVEDD	−0.012	0.913
LVEDDI	−0.251
LVM	−0.064	0.558
LVMI	−0.353
NT-proBNP	−0.250
^* Statistically significant results are in bold. ⁶ MWD – six-minute walk distance; CHF – chronic heart failure; r – correlation coefficient; – 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.
