Correlation analysis of miRNA expression and Cardiac Magnetic Resonance in HF patients. A- Correlation of intracellular lifetime of water (seconds) and expression of miR-423-5p. B- Correlation of extracellular volume (ECV) with expression of miR-128a-3p. Values related to heart failure with preserved ejection fraction (HFpEF) and heart failure with reduced ejection fraction (HFrEF) patients are presented in orange and in green, respectively. (The continuous lines and shaded areas represent linear regression fits with confidence ranges for the HFrEF and HFpEF subgroups, respectively. Pearson's R′ and the p-values are shown in colors corresponding to the two groups).
