Correlation of the New York Heart Association Classification and the 6‐Minute Walk Distance: A Systematic Review

ConclusionsAlthough there is an inverse correlation between NYHA II–IV and 6MWD, there is significant heterogeneity across studies in 6MWD within each NYHA class and overlap in 6MWD between NYHA I and II. The NYHA classification performs well in more symptomatic patients (NYHA III/IV) but less so in asymptomatic/mildly symptomatic patients (NYHA I/II). Nonetheless, the NYHA classification is an easily applied first‐line tool in everyday clinical practice, but its potential subjectivity should be considered when performing comparisons across studies.
