Syndromes of orthostatic intolerance: a hidden danger.

Summary, in English

Orthostatic hypotension (OH) is a relatively common heterogenous and multifactorial disorder, traditionally classified as neurogenic (less common but often more severe), or non-neurogenic (more common, with no direct signs of autonomic nervous system disease). The different clinical variants of orthostatic intolerance include initial, classical and delayed OH as well as postural tachycardia syndrome. Orthostatic instability may induce syncopal attacks either alone or in combination with other mechanisms, and is often dismissed as a precipitating factor. Moreover, prevalent OH is an independent risk factor for all-cause mortality and cardiovascular morbidity, and the majority of patients with OH are asymptomatic or have few non-specific symptoms. Management of symptomatic orthostatic intolerance includes both non-pharmacological and pharmacological methods but it is not always successful and may lead to complications. Future studies of OH should focus on mechanisms that lead to neurogenic and non-neurogenic OH, novel diagnostic methods, and more effective therapeutic modalities. © 2012 The Association for the Publication of the Journal of Internal Medicine.
