Objective:
To compare 24 h ambulatory blood pressure changes between patients with renovascular hypertension and essential hypertension.
Methods:
The 24 h ambulatory blood pressure of patients with age and gender matched renovascular hypertension (RVH, n = 51) was compared with that of patients with essential hypertension (EH, n = 51).
Results:
The 24 h, daytime and nighttime systolic blood pressures (SBP), diastolic blood pressures (DBP) and pulse pressures (PP) in RVH were significantly higher than in EH (all P < 0.05), especially the nocturnal SBP (P < 0.05). The SBP and DBP loads in RVH were 58.96% and 35.98% respectively, while blood pressure loads were around 20.00% in EH (P < 0.05). In patients with RVH, The nocturnal blood pressure fall was 5.39%, and only 27.50% patients were dippers, while the nocturnal blood pressure fall was 10.36% and 60.8% patients were dippers in EH.
Conclusion:
RVH patients have higher dynamic BP, PP, BP loads and blunted diurnal rhythm compared to those with EH.

Special considerations while measuring blood pressure
Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.
Blood Pressure
The average BP in an adult is typically around 120/80 mmHg (millimeters of mercury). In this measurement, the numerator (120) indicates the systolic pressure, which is the pressure in the arteries during the contraction of the heart's ventricles as blood is expelled. The denominator (80) represents the diastolic...
