Relationship between day-night rhythm and urinary microalbumin in patients with initial hypertension

Objective:To investigate the relationship between day-night rhythm,serum levels of high sensitive C.reactive protein (hs-CRP)and urinary microalbumin in the initial hypertension.Methods:186 essential hypertensive patients were divided into 2 groups according to the blood pressure-decreasing ratio,group A(dipping group)71 cases,group B(non-dipping group)115 cases.The grade of atheroma and hs-CRP was examined at the same time.Results:The difference of hs-CRP and the grade of urinary microalbumin were significant,group Bgroup A (P0.01).Conclusion:In 186 essential hypertensive patients,day-night rhythm correlated with inflammation and carotid atherosclerosis.
