Kidney transplant patients suffer from vascular abnormalities and high cardiovascular event rates, despite initial improvements post-transplantation. The nature of the progression of vascular abnormalities in the longer term is unknown. This pilot study investigated changes in vascular abnormalities over time in stable kidney transplant patients long after transplantation. Methods Brachial artery flow-mediated dilation (FMD), nitroglycerin-mediated dilation, carotid-femoral pulse wave velocity

... cf-PWV), anklebrachial pressure index, and common carotid artery intima-media thickness (CCA-IMT) were assessed in 18 kidney transplant patients and 17 controls at baseline and 3-6 months after. Results There was no difference in age (51±13 vs. 46±11; P=0.19), body mass index (26±5 vs. 25±3; P=0.49), serum cholesterol (4.54±0.96 vs. 5.14±1.13; P=0.10), systolic blood pressure (BP) (132±12 vs. 126±12; P=0.13), diastolic BP (82±9 vs. 77±8; P=0.10), or diabetes status (3 vs. 0; P=0.08) between transplant patients and controls. No difference existed in vascular markers between patients and controls at
