In this single-center study, we aimed to evaluate endothelial dysfunction, the leading cause of mortality in geriatric CKD patients. We kept patient exclusion criteria strict and considered it more rational to conduct this study in a patient group requiring proactive intervention by excluding patients with 'known' cardiovascular disease. For this purpose, we used some non-invasive parameters known in the literature (ultrasonographic measurement of carotid intima-media thickness, nailfold capillaroscopy, flow-mediated dilation). We also planned to measure serum sVE Cadherin levels, which have not been clearly evaluated in geriatric CKD patients before, as well as serum FGF23 levels. We also planned to evaluate the relationship and correlation of these different parameters with other standard biochemical and anthropometric measurements. Patient recruitment for the study took place between May 12, 2023, and September 11, 2023. We followed up for mortality for approximately 2.3 years.
