Abstract:
Objective To observe the impacts of valsartan combined with amlodipine or hydrochlorothiazide regimen on blood pressure variability (BPV) in elderly hypertensive patients.Methods Eighty elderly patients with hypertension were randomized into valsartan and amlodipine (the amlodipine group, n=38) or valsartan and hydrochlorothiazide (the hydro-chlorothiazide group,n=37) group.The 24-hour dynamic blood pressure was monitored at baseline, 6-week and 12-week after treatment for the blood pressure and blood pressure variability. The control rate of blood pressure was calculated at 6-week after treatment, and side effects were observed during the treatment.Results Values of 24 h systolic blood pressure (SBP), daytime SBP, nighttime SBP, morning SBP and 24 h systolic blood pressure variability (SBPV) were significantly low-er at 6-week and 12-week than those of baseline in both two groups(P<0.05). There was an interaction between the group-ing factors and time on 24 h SBP, daytime SBP, nighttime SBP, 24 h SBPV and daytime SBPV (P<0.05). At the 6 and 12-week treatment, 24 h SBP, daytime SBP, nighttime SBP and daytime SBPV were significantly lower in amlodipine group than those in hydrochlorothiazide group (P<0.05). At 12-week treatment, 24 h SBPV was significantly lower in amlodipine group than tjat in hydrochlorothiazide group (P<0.01). There were no significant differences in control rate of blood pressure and side effects between two groups. Conclusion Valsartan in combination with amlodipine or hydrochlorothiazide can both ef-fectively control BPV in elderly hypertensive patients, and valsartan conbined with amlodipine has better effects on lowering blood pressure and BPV.
