Evaluate the characteristics of Ambulatory blood pressure in CKD patients with normal casual blood pressure.Design and Method:
Selected 350 cases of CKD1–5 grade patients who was with normal casual blood pressure, Among them, Male were 136 cases and female were 214 cases, the age were average 62.65 ± 14.2 years old. The patients were into CKD normal blood pressure groups (146 cases) and elevated normal blood pressure groups (204 cases). According to the levels of blood pressure, fifty healthy persons were as a control group. Kidney disease was the primary and secondary glomerular diseases as well as renal tubular diseases. 24 hours blood pressure was monitoring with United states of Spacelab ambulatory blood pressure instruments, in these patients. The data was automatic analysis by software.Results:
There were 120 cases who had the average of ambulatory blood pressure increased, It was account for 34.3%. In elevated normal blood pressure groups whores 24 hours blood pressure and the average of diurnal blood pressure were significantly higher than those control groups and CKD normal blood pressure groups, P < 0.01. Masked hypertension (MHT) was 69 cases, the prevalence of MHT was 19.7%, Abnormal blood pressure pattern (diurnal rhythm loss) was 58.6% and in 205 cases, their blood pressure load was increased. It was account for 58.6%, the blood pressure load increased mainly in night.Conclusions:
The CKD patients who were with normal casual blood pressure, still exist some abnormal conditions such as the average of ambulatory blood pressure increased. Masked hypertension, nocturnal hypertension, abnormal the blood pressure load and the blood pressure pattern. It should be pay attention.
