  2. Orthostatic hypertension - Wikipedia

    en.wikipedia.org/wiki/Orthostatic_hypertension

    Orthostatic hypertension is a medical condition consisting of a sudden and abrupt increase in blood pressure (BP) when a person stands up. [1] Orthostatic hypertension is diagnosed by a rise in systolic BP of 20 mmHg or more when standing.

  3. Pathophysiology of hypertension - Wikipedia

    en.wikipedia.org/wiki/Pathophysiology_of...

    A diagram explaining factors affecting arterial pressure. Pathophysiology is a study which explains the function of the body as it relates to diseases and conditions. The pathophysiology of hypertension is an area which attempts to explain mechanistically the causes of hypertension, which is a chronic disease characterized by elevation of blood pressure.

    Multiple blood pressure readings (at least two) spaced 1–2 minutes apart should be obtained to ensure accuracy. [92] Ambulatory blood pressure monitoring over 12 to 24 hours is the most accurate method to confirm the diagnosis. [93] An exception to this is those with very high blood pressure readings, especially when there is poor organ ...

  5. Hypertensive emergency - Wikipedia

    en.wikipedia.org/wiki/Hypertensive_emergency

    Excessive reduction in blood pressure can precipitate coronary, cerebral, or kidney ischemia and, possibly, infarction. [citation needed] A hypertensive emergency is not based solely on an absolute level of blood pressure, but also on a patient's baseline blood pressure before the hypertensive crisis occurs.

  6. Labile hypertension - Wikipedia

    en.wikipedia.org/wiki/Labile_hypertension

    Caffeine: consumption of caffeine may constrict blood vessels that may stimulate and display unexpected spikes in blood pressure. Researchers believe that caffeine could possibly block hormones that normally keep arteries widened. Caffeine may also cause adrenal glands to release adrenaline which causes the blood pressure to dramatically increase.

    Stroke occurs when blood flow to the brain is blocked or there’s sudden bleeding in the brain. Unless treated quickly, it can lead to lasting brain damage, long-term disability or death.

  8. Hypertensive encephalopathy - Wikipedia

    en.wikipedia.org/wiki/Hypertensive_encephalopathy

    The impairment of cerebral blood flow that underlies hypertensive encephalopathy is still controversial. Normally, cerebral blood flow is maintained by an autoregulation mechanism that dilates arterioles in response to blood pressure decreases and constricts arterioles in response to blood pressure increases. This autoregulation falters when ...

  9. Blood pressure - Wikipedia

    en.wikipedia.org/wiki/Blood_pressure

    Blood pressure (BP) is the pressure of circulating blood against the walls of blood vessels. Most of this pressure results from the heart pumping blood through the circulatory system. When used without qualification, the term "blood pressure" refers to the pressure in a brachial artery, where it is most commonly measured.
