Details of BA and PA flow-mediated, endothelium-dependent dilation and GTN-mediated, endothelium-independent dilation in a group of healthy subjects
| BA | PA | P Value | |
|---|---|---|---|
| Diameter, mm | 4.2 ± 0.6 | 5.9 ± 1.0 | <0.001 |
| Peak FMD diameter, mm | 4.5 ± 0.6 | 6.3 ± 1.0 | <0.001 |
| Time to peak diameter, s | 72 ± 28 | 151 ± 79 | <0.001 |
| FMD, % | 7.3 ± 2.7 | 6.7 ± 3.0 | 0.38 |
| SRAUC*, s (103) | 15.3 ± 9.2 | 14.0 ± 7.7 | 0.36 |
| Peak GTN diameter, mm | 5.0 ± 0.7 | 6.5 ± 0.9 | <0.001 |
| GTN, % | 18.1 ± 6.1 | 9.1 ± 3.5 | <0.001 |
Values are means ± SD; n = 32 subjects. The SRAUC is presented, being the stimulus for arterial dilation during the FMD response.

Due to technical problems, we could not record the PA SRAUC in 6 subjects.
