Evaluation of 24-Hour Ambulatory Blood Pressure Monitoring in Patients with Chronic Kidney Disease with Normal Casual Blood Pressure

摘要

This study evaluated 24-hour ambulatory blood pressure (ABP) monitoring in patients with chronic kidney disease (CKD) who had a normal casual blood pressure (CBP) of less than 140/90 mmHg. A total of 350 patients with CKD (Stages 1-5) and a normal CBP were included, and 24-hour ABPs were monitored. Of these patients, 147 patients (42.0%) exhibited increased mean ABP; 69 patients (19.7%) exhibited masked hypertension; 199 patients (56.9%) exhibited an abnormal BP mode (circadian rhythm disappearing); and 204 patients (58.3%) exhibited increased BP load. The 24-hour ABP and mean day and night BPs in patients with higher CBP were significantly higher than those in patients with normal CBP and healthy controls (P0.01). Results indicate that abnormal BPs exist in patients with CKD who exhibit normal CBPs.
