IL-1 β (A), IL-2 (B) and IL-4 (C) levels in acute (n = 12) and chronic heart failure (n = 19) patients and in the control group (n = 9). Boxes with lines and whiskers represent the interquartile range, median values and the outliers. The individual values are presented with black dots (control group), squares (acute HF) or triangles (chronic HF). Statistical analysis was performed with one-way ANOVA test with Tukey post-hoc test. * p < 0.05, ** p < 0.001 vs. chronic heart failure group.
