Relationship between total cardiac MC density (a), percentage of MC degranulation (b), and degranulated MC density (c) to the cardiomyocyte cross-sectional area from all four experimental group combinations (see Fig. 1 caption for groups). Linear regression analysis indicated no relationship between cardiomyocyte cross-sectional area and total cardiac mast cell density (r ² = 0.08933) or percentage of MC degranulation (r ² = 0.07847), but a significant relation was found between degranulated MC density and cardiomyocyte size (r ² = 0.2376)
