  1. 1. Blood pressure-dependent changes in plasma volume, glycocalyx and platelet function during anaesthesia -Clinical and experimental studies

    Författare :Tor Damén; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; anaesthesia; blood pressure; hypotension; norepinephrine; haematocrit; plasma volume; atrial natriuretic peptide; glycocalyx; platelet aggregation;

    Sammanfattning : Background: Worldwide, more than 300 million surgeries are performed each year. General anaesthesia provides the surgical patient with a state of controlled loss of sensation and awareness. It is common that general anaesthesia causes hypotension. Anaesthesia-induced hypotension is associated with haemodilution and increased plasma volume (PV). LÄS MER

  4. 3. Blood pressure in very old age : determinants, adverse outcomes, and heterogeneity

    Författare :Bodil Weidung; Yngve Gustafson; Håkan Littbrand; Bo Carlberg; Peter Nordström; Sölve Elmståhl; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Blood pressure; aged 80 and over; hypertension; hypotension; mortality; stroke; gait speed; cognition disorders; dementia; cohort study;

    Sammanfattning : Background: High blood pressure (BP) is the leading risk factor for disease and mortality worldwide. However, risks associated with high BP in very old age (≥ 80 or ≥ 85 years) are not entirely understood, as the majority of scientific studies have been performed with younger populations and existing scientific knowledge about very old individuals is sometimes contradictory.

  5. 4. Posture and brain function in dementia. A study with special reference to orthostatic hypotension

    Författare :Ulla Passant; Sektion IV; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; falls and fractures.; white matter disease; hypoperfusion; frontal lobes; regional cerebral blood flow; blood pressure; orthostatic hypotension; Organic dementia; normal subjects; Psychiatry; clinical psychology; psychosomatics; Psykiatri; klinisk psykologi; psykosomatik;

    Sammanfattning : Orthostatic hypotension (OH) is believed to be an important cause of cerebral hypoperfusion, leading to chronic fatigue, blurred vision, unsteadiness, dizziness and sometimes syncope. It may also result in episodes of confusion, falls and fractures. The coupling between OH and organic dementia is not clear. LÄS MER

  7. 5. Cardiovascular health, orthostatic hypotension, and cognitive aging

    Författare :Xin Xia; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Cardiovascular health (CVH) plays an important role in dementia development. Ideal CVH, defined by Life’s Simple 7 (LS7), has been associated with a lower risk of dementia in older adults. Orthostatic hypotension (OH) may be a novel cardiovascular risk factor that can affect dementia development. LÄS MER
