[Blood flow in affected major arteries of head in hypertensive patients]
Aim:
To assess blood flow in intracranial internal carotid and vertebral arteries in patients with essential hypertension (EH) and hemodynamically insignificant atherosclerotic lesions and deformities of major arteries of the head (MAH).
Materials And Methods:
The blood flow was assessed in 55 untreated patients (mean age 53 +/- 1 years) with mild, moderate or severe hypertension. 20 healthy patients served control. Duplex scanning was performed using ACUSON unit.
Results:
Total blood flow (Q) in hypertensive subjects appeared significantly subnormal. It was less in patients with hemodynamically insignificant atherosclerotic stenosis and flexures of the carotid and vertebral arteries than in patients with affection of the carotid arteries only. Q in MAH was lower in smokers than in non-smokers.

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)...
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.
