Fig. 1From: Metformin improves lipid metabolism and reverses the Warburg effect in a canine model of chronic atrial fibrillationMetformin decreases lipid accumulation in chronic AF. a, b FFA and TG contents in LAA; c Representative images of oil red O staining for lipids (red color, × 40). SR, sinus rhythm; AF, atrial fibrillation; MET, metformin. * P < 0.05 versus SR group; # P < 0.05 versus AF group; n = 6 per group.
