[Daily blood pressure profile in patients with hypertensive encephalopathy]
Abstract:
The purpose of the study was to study daily variations of blood pressure (BP) in patients with hypertensive encephalopathy (HE). Daily BP monitoring (DBPM) was made in 100 patients with different stages of HE. In HE, a proportion of patients from a non-dippers group substantially increased. An excessive nocturnal reduction in systolic BP (SBP) was more common. A dippers group was predominant in the controls. The daily index for SBP significantly decreased in patients with stage I HE; that for diastolic BP (DBP) reduced in those with stages I-II HE. The morning increase rate (MIC) of BP was studied. MIC of SBP was higher in patients with HE, which was most commonly observed in the non-dippers group. There was a more significant reduction in DBP in combination with high MIC in 10% of the examinees.

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.
Alterations in Blood Pressure
Hypertension (High blood pressure)
Hypertension occurs when blood pressure readings consistently exceed the normal range. It is diagnosed when systolic blood pressure (the top number, indicating pressure while the heart beats)...
