Objective: To study 24-hour blood pressure variability (BPV) in essential hypertensives(EH) and to observe the effects of enalapril on BPV in the patients. Methods: BPV were evaluated in 132 EH patients (EH Ⅰ-Ⅱ group 90
EH Ⅲ group 42) using ambulatory blood pressure monitoring
and compared with 60 normal controls.45 EH Ⅰ-Ⅱ patients were treated with enalapril for 4 weeks by randomized single-blind study.The BPV were measured before and after treatment. Results: The SBPV and MAPV during 24-hour period
daytime or nighttime were significantly higher both EH Ⅰ-Ⅱ and EH Ⅲ than control group ( P <0.01 or 0.05)
but the DBPV was higher only in EH Ⅲ than control group( P <0.05).The SBPV
DBPV or MAPV during every interval were higher apparently in EH Ⅲ than EH Ⅰ-Ⅱ( P <0.05 or 0.01).There were no difference in BPV before and after treatment ( P >0.05).Conclusion:There was a significant increase in BPV(especially in SBPV) and in particular EH Ⅲ group than control group There was no effect in BPV with EH Ⅰ-Ⅱ group by enalapril treatment for 4 weeks.
