Central blood pressure in chronic kidney disease: latest evidence and clinical relevance

Area of Science:

• Nephrology
• Cardiology
• Clinical Medicine

Background:

• Chronic kidney disease (CKD) is strongly linked to cardiovascular disease (CVD), with lower glomerular filtration rates correlating with higher CVD risk.
• CKD is now recognized as an independent CVD risk factor, included in major prevention guidelines.
• Arterial stiffening and left ventricular structural changes (hypertrophy, fibrosis) are key mechanisms linking CKD to CVD.

Purpose of the Study:

• To review the rationale for measuring central blood pressure in CKD patients.
• To evaluate if central blood pressure measurement provides additional prognostic information beyond peripheral blood pressure in CKD.

Main Methods:

• Literature review of studies on CKD, cardiovascular disease, and blood pressure measurement.
• Analysis of data from imaging and epidemiological studies on pathogenic mediators.
• Discussion of the clinical utility of central vs. peripheral blood pressure in CKD prognosis.

Main Results:

• A significant association exists between CKD and cardiovascular disease.
• Arterial stiffening and left ventricular disease are identified as primary drivers of CVD in CKD.
• The prognostic value of central blood pressure measurement in CKD requires further investigation.

Conclusions:

• Central blood pressure measurement may offer incremental prognostic value in CKD patients.
• Further research is warranted to establish the role of central blood pressure in managing cardiovascular risk in CKD.
• Understanding the interplay between CKD and cardiovascular pathology is crucial for effective prevention strategies.
