Increase of plasma IL-9 and decrease of plasma IL-5, IL-7, and IFN-γ in patients with chronic heart failure

Table 2 Correlation between cytokine plasma levels and duration of disease or ejection fraction

Cytokine	IL-5	IL-9
Duration of disease	r = -0.475 (p = 0.05)	n.s.
Left Ventricular Ejection Fraction	n.s.	r = -0.364 (p = 0.02)

A negative Pearson's correlation coefficient (r) indicates that cytokine expression inversely correlates
with the variable in exam (e.g. : patients with longer disease duration had smaller concentrations of
plasmatic IL-5 in comparison with patients more recently diagnosed).
A statistically significant inverse correlation of IL-9 plasma levels with left ventricular ejection fraction
was found among the ICM group only (n = 42).
An inverse correlation between IL-5 plasma levels and duration of disease was found in NYHA III-IV
ICM patients only (n = 18).
