The relationship between hypertension and cerebrovascular disease is well established. As blood pressure is a dynamic and continually distributed variable, 24 h ambulatory blood pressure monitoring may be valuable as a risk stratifying tool in determining the "hypertensive load" as assessed by the presence of dipping or non-dipping status of an individual. Indeed, the association between reduced nocturnal blood pressure dipping and increased target organ damage is well established. Raised blood pressures are often seen in those presenting with strokes, although the precise mechanisms are uncertain. The relationship between intracerebral haemorrhage, which accounts for up to 15% of strokes in Caucasians, and blood pressure patterns is not well known. Understanding these inherent diurnal rhythms of blood pressure variation could help us unravel their significance and impact on cerebrovascular disease.

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)...

Blood Pressure: Hypertension and Hypotension
Normal blood pressure is 120/80 mm Hg. Elevated blood pressure is 120-129/under 80 mm Hg. Hypertension, warranting treatment at 130/80 mm Hg, is often asymptomatic and can lead to severe cardiovascular events, aneurysms, peripheral arterial disease, chronic renal disease, or cardiac...
01:28Special 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.
