FIGURE 1.

miR‐454 is downregulated in HF and negatively correlated with the grade of HF. A, The expression of miR‐454 in peripheral blood of HF patients with AMI complicated with HF and healthy individuals determined by RT‐qPCR; n = 72; *P < .05. B, miR‐454 expression in peripheral blood of healthy individuals and patients with different grades of HF determined by RT‐qPCR; *P < .05. Measurement data are displayed as mean ± standard deviation. Independent sample t‐tests were used for comparing data between the two groups, and one‐way ANOVA for comparison of data among multiple groups
