a Schematic image showing the NO-patch treatment for a chronic rat MI model. b Representative Masson trichrome staining images of the heart 4 weeks after different treatments. Scale bar, 5 mm. c The infarct size was calculated according to Masson staining. d–e. Quantitative data of echocardiography for measurement of cardiac function, and representatively, the left ventricular (LV) ejection fraction (LV-EF) and fraction shortening (LV-FS) were shown. Data are expressed as mean ± SEM, n = 6 animals for each group. Significant differences were detected by two-tailed one-way (b) or two-way (d and e) ANOVA with Tukey’s multiple comparisons test. LAD: left anterior descending artery.
