From: 17β-estradiol effects on human coronaries and grafts employed in myocardial revascularization: a preliminary study

Figure 3

The effect of increasing concentrations (3–30–300–3000 nmol/l) of 17β-estradiol on vessels with and without endothelium. The relaxation is expressed as the percentage of the maximum effect obtained with PGF. The peak tension with PGF was 3.2 ± 1.3 for intact vessels and 3.4 ± 1.0 for denuded vessels. There were no significant differences in vascular response to estrogen in groups with or without endothelium at each estrogen concentration (n = 66 for group with endothelium, n = 66 for group without endothelium, p > 0.05).
