Effects of AgomiR-210-3p on atrial function and structure in rats. A qRT-PCR analysis of the expression of miR-210-3p in the rats heart (n = 7; ***P < 0.001 compared with the Ctr and NC groups). B Representative echocardiographic images captured 4 weeks after the AgomiR-210-3p infusion treatment. C The LAD were calculated at 4 weeks in rats (n = 7; *P < 0.05). D Representative electrocardiogram (ECG) traces after atrial burst pacing (left) at 3000 beats/min. E Probability of AF induction by atrial burst pacing of the induced AF episodes (n = 7; *P < 0.05). F, G TGFβ1, α-SMA and Collagen I protein levels were determined in atrial tissues (n = 7; *P < 0.05)
