Coronary flow reserve in pregnant and non-pregnant rats.

<p>Mean ±SEM for coronary flow reserve calculated from peak velocities (A, C) and velocity time integrals (B, D). Comparisons between groups were made using independent samples T-test (A, B) and one-way ANOVA and Holm-Sidak post hoc test (C, D). SEM, standard error of the mean, NP, non-pregnant, Ang2, Angiotensin II, TAC, transverse aorta constriction, p<0.05 compared to non-pregnant sham (*).
