A Comparison of Measures of Endothelial Function in Patients with Peripheral Arterial Disease and Age and Gender Matched Controls

Table 2

RHI, FMD, and NO results for age and gender matched controls and patients with PAD.

	Controls ()	PAD ()
RHI median, IQR	1.92, 1.84–2.24	1.64, 1.34–2.01
FMD% median, IQR	3.77, 1.87–6.15	2.16, 0.59–4.17
NO (μmol) median, IQR	13.05, 5.58–19.06	7.70, 6.17–15.07

PAD: peripheral arterial disease, IQR: interquartile range, FMD: flow-mediated dilatation, RHI: reactive hyperaemia index, and NO: nitric oxide.
