Tissue immune cell infiltration. (a) Immune cell difference between HF and normal samples (“” means , “” means , “” means ). The red dots represent each HF sample, while the blue dots represent each normal sample; (b) immune cell subtype correlation. The specific correlation values of 22 immune cells are displayed, in which the darker color of each correlation square represents higher correlation, and the lighter color represents low correlation. Red represents the degree of positive correlation, while blue represents the degree of negative correlation.
