Abstract
Evaluation was made of the circadian rhythm of blood pressure (BP) by using ABPM in patients with CKD. There was a substantial difference in the relationship between heart rate (HR) and BP in 3 CKD modalities (ND (non-dialysis), HD (hemodialysis), and PD (peritoneal dialysis). Such differences were characterized by a greater BP level in HD, and the predominance of non-dipper pattern in PD. Despite the assessment by cardio-ankle vascular index (CAVI), coefficient of variation of R-R intervals (CVRR) and ultrasonic echocardiography (UCG), reasons to explain the difference in the HR-BP relationship were unknown. Future studies will be needed to further investigate the usefulness of ABPM in CKD.
