- Values are the mean ± SEM. n, number of rats; NA, numerical density; LV, length density; VV, volume density. A two-way ANOVA revealed a statistically significant interaction between the effects of sex and the experimental model on the arteriolar diameter in LV free wall, F (1, 22) = 8.943, P = 0.009, and on arteriolar volume density in septum, F (1, 22) = 10.903, P = 0.005. *P < 0.05 vs. corresponding Sham group; §P < 0.05, §§P < 0.01, and §§§P < 0.001 vs. M-Sham; †P < 0.05, ††P < 0.01, and †††P < 0.001 vs. M-MI.
