Data are presented as Spearman rank correlation coefficients. Significance of correlations after Bonferroni adjustment of p values (α/48): *p<0.01; ** p<0.001; R = variance of dependent variable explained by multiple regression analysis.
CHF, congestive heart failure; general health p, general health perception; LVEF, left ventricular ejection fraction; NYHA, New York Heart Association; peak Vo2, peak oxygen uptake.
