Analysis of the circadian rhythm of blood pressure in 514 patients with primary hypertension

To study the relationship between the types of blood pressure circadian rhythm and the indexes such as systolic blood pressure, diastolic blood pressure, pulse pressure, age, sex, arteriosclerosis of fundus oculi, and other blood serum markers (BUN, CRE, NO, ET). Examination of fasting blood BUN, CRE, NO, ET and 24h ambulatory blood pressure monitoring were performed in 514 initially untreated patients with primary hypertension. The patients were divided into four groups according to their blood pressure rhythm (deep dippers, nondippers, dippers and reverse dippers). There were significant deferences in systolic blood pressure, diastolic blood pressure, pulse pressure and age in different group. But there were no significant deferences in sex, arteriosclerosis of fundus oculi, and other serum markers (BUN,CRE,NO,ET). The types of blood pressure rhythm are influenced by age, but it is not associated with BUN, CRE, NO, ET and arteriosclerosis of fundus oculi.
