RIC remarkably promoted cardiac remodeling and angiogenesis after myocardial infarction. (A) Histopathological analysis of heart tissues by HE, Masson, vWF IHC staining, respectively (scale bar= 100 μm); (B) RIC treatment significantly decreased the infarction ratio; (C) RIC treatment significantly increased left ventricular ejection fraction; (D) RIC treatment significantly increased left ventricular fractional shortening. Data were shown as the mean ± SD (n = 5/each group), * P<0.05 compared with the group MI.
