Orthostatic Hypotension in Older Adults.pdf
This book provides a comprehensive and practical guide to orthostatic hypotension (OH) for doctors and nurses involved in the care of older adults, together with a state-of-the-art update on OH, covering its epidemiology, pathophysiology, assessment, diagnosis, causes, prevention, management, and relevance for geriatric practice. In addition, it addresses mechanisms of orthostatic tolerance and other orthostasis related conditions, as well as drugs, comorbidities and geriatric syndromes related to OH.
The homeostatic ability to maintain blood pressure while standing requires an adequate blood volume and the integrity of the nervous system, heart, blood vessels and muscle pump. However, in older adults, some age-related factors can contribute to the development of OH. For example, decreased baroreflex sensitivity, ?-1-adrenergic vasoconstrictor response to sympathetic stimuli, parasympathetic activity, renal salt and water conservation, increased vascular stiffness and decreased ventricular diastolic filling, as well as concentrated capacities of the kidney may be associated with changes in postural blood pressure. It has also been shown that OH is associated with falls, cardiac events, heart failure, stroke, reduced quality of life, and increased risk of overall mortality in these patients.
"Orthostatic Hypotension in Older Adults" will be of considerable interest to all professionals working in the fields of geriatrics, geriatric psychiatry, neurology, internal medicine, cardiology, and emergency medicine, or working with older people in hospitals or in their community.
The aim of this systematic review was to determine the prevalence of orthostatic intolerance symptoms in older adults with initial orthostatic hypotension.
The study aims to describe the characteristics of the older people with type 2 diabetes mellitus in Brazil and France who presented orthostatic hypotension and associated factors. This is a cross-sectional descriptive and analytical study, in which 248 Brazilian older adults with diabetes aged 65 or more and 987 older adults French with aged 75 or over, evaluated for the outcome of orthostatic ...
Orthostatic hypotension (OH) has been linked to dementia in older people in several longitudinal studies.
7(6), 557-560 (2009) "The problem has, at its root, the conundrum that both hypertension per se, and many antihypertensive medications, can exacerbate age-related impairments of the physiological processes that regulate blood flow after orthostasis." The clinical combination of ...
A lower baseline HR in the older adults may be related to a decrease in the intrinsic HR with aging . The present investigation demonstrated that the orthostatic hypotension observed in the older adults at the onset of a LBNP of −40 Torr (Fig.2) was related to a diminished tachycardiac response
Hypertension treatment has been implicated in falls, syncope, and orthostatic hypotension (OH), common events among older adults.
