Clinical Trial Summary

Diurnal variations in the cardiovascular system apparent in healthy individuals, are different in chronic kidney disease patients. Therefore, diurnal variations in arterial stiffness may also differ in chronic kidney disease patients. This study aims to identify and evaluate diurnal variations in arterial stiffness in chronic kidney disease patients and compare them to those in age matched healthy controls.

Outcome

Type Measure Description Time frame Safety issue
Primary Diurnal variations in arterial stiffness The principal objective of this study is to evaluate whether diurnal variations in arterial stiffness are blunted in chronic kidney disease compared to healthy age matched controls Over one 26 hour period arterial stiffness measurements will be obtained every 30 minutes from 7am to 12am and every 60 minutes from 12am to 7am
Secondary Diurnal variations in aortic and brachial blood pressure Secondary objective of this study is to evaluate whether diurnal variations in aortic and brachial blood pressure are blunted in chronic kidney disease compared to healthy age matched controls Over one 26 hour period blood pressure measurements will be obtained every 30 minutes from 7am to 12am and every 60 minutes from 12am to 7am
Secondary Relationship between changes in blood pressure and arterial stiffness Secondary objective of this study is to evaluate whether diurnal variations in arterial stiffness are dependent on changes in blood pressure in both chronic kidney disease patients and age matched controls. Over one 26 hour period
