Insights
Orthostatic hypotension (OHT) is a common condition, especially in older adults, linked to falls and serious health risks. Diagnosis involves simple tests, with advanced options for complex cases, guiding non-drug treatments.
Area of Science:
- Cardiology
- Neurology
- Geriatrics
Context:
- Orthostatic hypotension (OHT) affects 1% of the population, increasing with age.
- It is associated with falls, syncope, cognitive decline, and cerebrovascular events.
Purpose:
- To outline diagnostic approaches for orthostatic hypotension.
- To guide therapeutic strategies based on identified causes and functional impairment.
Summary:
- OHT diagnosis often relies on clinical examination and simple tests.
- Advanced investigations like head-up tilt tests, Valsalva maneuvers, cardiac MIBG scintigraphy, and urinary catecholamines aid in identifying baroreflex arc or autonomic nervous system dysfunction.
- Treatment prioritizes non-pharmacological interventions.
Impact:
- Improved diagnostic accuracy for OHT.
- Personalized treatment plans for OHT patients.
- Reduced morbidity and mortality associated with OHT.
Abstract:
Orthostatic hypotension (OHT) is a common symptom that affects about 1% of the population. Its prevalence increases with age. In addition to the morbidity related to falls and syncope, OHT is a risk factor for cognitive decline and cerebrovascular morbidity and mortality. In most cases, its cause is easily found by the examination and some simple explorations. For severe and/or less obvious mechanism, some paraclinical methods of investigation can be proposed. These include head upright tilt-test and Valsalva maneuver. Both explore the entire baroreflex arc, and are realised by non-invasive measurements of heart rate and blood pressure. Other tests explore more specifically the parasympathetic outflow tract or sympathetic. In some situations cardiac MIBG scintigraphy and urinary catecholamines may be useful. The respective choice of these tests depends on the clinical setting and suspected type of dysautonomic lesion. Identifying the cause and assessment of functional impairment guide the therapeutic choices, which are primarily based on non-pharmacological approach.
