Impaired Mitophagy: A New Potential Mechanism of Human Chronic Atrial Fibrillation

Figure 1

Impaired cardiac autophagy in patients with chronic AF. (a) Representative immunofluorescence images and semiquantitative analysis of LC3B in RAA (n = 9 per group). (b) Representative western blots and quantification of protein expressions of LC3B and p62 in RAA (the SR group, n = 16; the AF group, n = 18). Scale bar = 20 μm.  < 0.05 vs the SR group. SR, sinus rhythm; AF, atrial fibrillation; RAA, right atrial appendage.
