Chronic Kidney Disease
Conditions
Brief 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.

Eligibility
Inclusion criteria
* Systolic blood pressure \<160 whether or not on antihypertensive medication * diastolic blood pressure \<100mmHg whether or not on antihypertensive medication * Chronic kidney disease stage 2-5

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Diurnal variations in arterial stiffness | 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 | 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 |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Diurnal variations in aortic and brachial blood pressure | 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 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 |
| Relationship between changes in blood pressure and arterial stiffness | Over one 26 hour period | 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. |
