Correlation of B-type natriuretic peptide level to 6-min walk test performance in patients with left ventricular systolic dysfunction

Prognostic value of the 6 min walk test and self-perceived symptom severity in older patients with chronic heart failure

“…Our findings showed a moderate correlation between the 6-MWT and log NT-proBNP. This is similar to the findings of Wieczorek et al 50 who compared BNP concentration to 6-MWT in 44 patients with CHF. A significant inverse correlation was observed between BNP and 6-MWT (r ¼20.47, P , 0.001).…”

Invasive and Noninvasive Correlations of B‐Type Natriuretic Peptide in Patients With Heart Failure Due to Chagas Cardiomyopathy

“…The finding of an inverse correlation between BNP level and functional capacity is noteworthy and is in accordance with other studies. 34 The 6-minute walking test is a measure of submaximal exercise that correlates with daily activities. This correlation means that we can trust BNP levels to infer exercise capacity, ie, the higher the BNP level, the lower the exercise capacity.…”

Plasma brain natriuretic peptide levels, right ventricular volume overload and exercise capacity in adolescents after surgical repair of tetralogy of Fallot

“…Brain natriuretic peptide (BNP) is secreted by the ventricular myocytes in response to volume and pressure overload [15]. In adults, plasma BNP level aids the diagnosis of heart failure [16,17], correlates with New York Heart Association functional class status [18][19][20], correlates with left ventricular systolic function [21,22], and predicts adverse outcomes in acute and chronic heart disease [23,24]. Recently, plasma BNP level has been reported to be useful in the identification of ventricular dysfunction [25,26] and stratification of heart failure [27] in patients with congenital heart disease.…”
