Fig. 5From: Early left ventricular microvascular dysfunction in diabetic pigs: a longitudinal quantitative myocardial perfusion CMR studyMasson’s trichrome and CD31 staining of the myocardium in diabetic pigs with different disease courses. Masson staining showed that fibrosis was deposited in the extracellular space and surrounding blood vessels of the myocardium, and CVF increased gradually; CD31 staining showed no significant decrease in MVD (< 10%) with the progression of disease duration. CVF, collagen volume fraction; MVD, microvascular densityBack to article page
