Role of Ambulatory Blood Pressure Monitoring (ABPM) in chronic kidney patients: a review

Abstract

About 90%of patients with chronic kidney disease (CKD) have arterial hypertension; the main international guidelines recommend maintaining blood pressure (BP) values below 130/80 mmHg to reduce the cardio-renal risk in this population. Twenty-four-hour Ambulatory Blood Pressure Monitoring (ABPM) is the golden standard for the identification of the BP profiles and patterns, as well as for the assessment of the circadian rhythm and BP variability. The correct interpretation of ABPM allows to optimize anti-hypertensive treatment and to reduce cardio-renal risk in CKD patient.

In fact, in patients with CKD, the ABPM has a greater role in terms of renal and cardio-vascular prognosis when compared to clinical BP measurements. Patients with ABPM in target present a low cardio-renal risk, regardless of clinical BP values; on the contrary, if the clinical PA is normal and the ABPM not in target, this risk increases significantly. Moreover, in the CKD population, non-dipping is associated with a higher risk of cardiovascular events and end stage renal disease (ESRD), making identifying nocturnal hypertension greatly important.

Therefore, ABPM is an instrument of primary importance in the diagnostic and therapeutic work-out of renal patients.
