BACKGROUND/AIMS: Ambulatory blood pressure monitoring (ABPM) in chronic kidney disease (CKD) patients has been extensively studied, but few investigations have attempted to relate ABPM with CKD stages. The objectives of this article were to compare ABPM parameters for the diagnosis and treatment determination of CKD with daytime clinic blood pressure (BP) measurements. We also investigated BP and renal injury in combined hypertension and CKD. We supposed ABPM was important in combined hypertension and CKD.
METHODS: We compared ABPM in hypertension patients, including 152 patients with combined hypertension and CKD. Patients with combined hypertension and CKD were grouped according to severity into stages 1 through 3 (Stage 1-3) and stages 4 and 5 (Stage 4-5).
RESULTS: In the Stage 4-5 group, systolic BP (SBP) (daytime, nighttime and 24 h mean), diastolic BP (DBP), pulse pressure and SBP standard deviations (SD) (daytime and 24 h) were higher. SBP and DBP loads were significantly higher in the Stage 4-5 group. The nighttime load was higher than the daytime load. Mean arterial pressure (MAP) was higher and heart rates (HR) were faster in the Stage 4-5 group.
CONCLUSIONS: BP load should be a component employed in ABPM to determine cardiovascular risk stratification. MAP and HR might be associated with risk to develop end-stage renal disease.
