Assessment of myocardial tissue electric-contraction coupling, revascularization and apoptosis at postoperative Day 28. A Representative immunofluorescence images co-stained by CX43 (green) and α-actinin (red) (Scale bars: 50 μm, enlarged images: 20 µm); CD31 (green) and α-SMA (red), (Scale bars: 50 μm); TUNEL (green) and DAPI (blue) (Scale bars: 200 μm). Quantitative analysis of the B neovessels in the infarct regions and C cardiomyocyte apoptosis by TUNEL positive cells in normal myocardium adjacent to severely fibrotic tissue. *P < 0.05 and **P < 0.01, ***P < 0.001, ****P < 0.0001
