Figure 1.

The serum expression of miR‐939‐5p was higher in chronic heart failure patients than normal people. A, The relative serum miR‐939‐5p expression was detected and compared in NYHA I‐II grade, NYHA III‐IV grade CHF patients and normal people by qRT‐PCR, adding cel‐39‐3p as external control. Data are mean ±SEM. ^* P < .05 and ^** P < .01. B and C, The correlation between BNP and miR‐939‐5p level in CHF patients were analysed by Spearman’s correlation. B, there is no obvious correlation in CHF NYHA I‐II patients (n = 41) P > 0.05. C, miR‐939‐5p expression in CHF NYHA III‐IV patients was significantly correlated with BNP level, (n = 24) r = .701, P < 0.01
