    Three risk factors — high blood pressure, smoking and atrial fibrillation (which is an irregular heart rhythm) were linked with higher risk of severe compared to mild-moderate stroke,” said Dr ...

  3. Stroke - Wikipedia

    en.wikipedia.org/wiki/Stroke

    High blood pressure accounts for 35–50% of stroke risk. [110] Blood pressure reduction of 10 mmHg systolic or 5 mmHg diastolic reduces the risk of stroke by ~40%. [111] Lowering blood pressure has been conclusively shown to prevent both ischemic and hemorrhagic stroke. [112] [113] It is equally important in secondary prevention. [114]

  4. Cerebral infarction - Wikipedia

    en.wikipedia.org/wiki/Cerebral_infarction

    Cerebral infarction, also known as an ischemic stroke, is the pathologic process that results in an area of necrotic tissue in the brain (cerebral infarct). [1] In mid to high income countries, a stroke is the main reason for disability among people and the 2nd cause of death. [2]

  5. Brain ischemia - Wikipedia

    en.wikipedia.org/wiki/Brain_ischemia

    Brain ischemia has been linked to a variety of diseases or abnormalities. Individuals with sickle cell anemia, compressed blood vessels, ventricular tachycardia, plaque buildup in the arteries, blood clots, extremely low blood pressure as a result of heart attack, and congenital heart defects have a higher predisposition to brain ischemia in comparison to the average population.

  6. Penumbra (medicine) - Wikipedia

    en.wikipedia.org/wiki/Penumbra_(medicine)

    Immediately following the event, blood flow and therefore oxygen transport is reduced locally, leading to hypoxia of the cells near the location of the original insult. This can lead to hypoxic cell death ( infarction ) and amplify the original damage from the ischemia ; however, the penumbra area may remain viable for several hours after an ...

  7. Cerebrovascular disease - Wikipedia

    en.wikipedia.org/wiki/Cerebrovascular_disease

    The most common presentation of cerebrovascular disease is an ischemic stroke or mini-stroke and sometimes a hemorrhagic stroke. [2] Hypertension (high blood pressure) is the most important contributing risk factor for stroke and cerebrovascular diseases as it can change the structure of blood vessels and result in atherosclerosis . [ 5 ]

  8. Cerebral circulation - Wikipedia

    en.wikipedia.org/wiki/Cerebral_circulation

    Cerebral perfusion pressure is the net pressure gradient causing cerebral blood flow to the brain (brain perfusion). It must be maintained within narrow limits; too little pressure could cause brain tissue to become ischemic (having inadequate blood flow), and too much could raise intracranial pressure .

  9. Cerebral perfusion pressure - Wikipedia

    en.wikipedia.org/wiki/Cerebral_perfusion_pressure

    Cerebral perfusion pressure, or CPP, is the net pressure gradient causing cerebral blood flow to the brain (brain perfusion).It must be maintained within narrow limits because too little pressure could cause brain tissue to become ischemic (having inadequate blood flow), and too much could raise intracranial pressure (ICP).
