HIPOTENSION ORTOSTATICA PDF

Medication[ edit ] Tetrahydrocannabinol Orthostatic hypotension can be a side-effect of certain antidepressants , such as tricyclics [11] or monoamine oxidase inhibitors MAOIs. Alpha1 blockers inhibit vasoconstriction normally initiated by the baroreceptor reflex upon postural change and the subsequent drop in pressure. People suffering from anorexia nervosa and bulimia nervosa often suffer from orthostatic hypotension as a common side-effect. Consuming alcohol may also lead to orthostatic hypotension due to its dehydrating effects. For example, changing from a lying position to standing loses about ml of blood from the thorax , with a decrease in systolic and diastolic blood pressures. One response is a vasoconstriction baroreceptor reflex , pressing the blood up into the body again.

Sus Ameteala ocazionala poate fi relativ minora, rezultatul unei usoare deshidratari si nivelului scazut de zahar din sange. Aceasta poate sa apara dupa ce o persoana a stat o perioada indelungata la soare, dupa ce a facut o baie prea fierbinte sau sta o peroada indelungata de timp in picioare.

Daca aceste simptome apar ocazional, nu reprezinta un motiv de ingrijorare. Este important sa se consulte medicul daca apar manifestari frecvente de hipotensiune arteriala ortostatica, intrucat acestea pot fi caracteristice unor probleme mult mai grave. Poate fi utila evidenta simptomelor, a duratei acestora si a activitatii care le-a decalnsat.

Cauze Sus Atunci cand o persoana se ridica in picioare, ca urmare a gravitatiei, sangele se acumuleaza la nivelul membrelor inferioare. Acest lucru duce la scaderea tensiunii arteriale deoarece catre inima circula mai putin sange. In mod normal, celule speciale baroreceptorii stimuleaza inima sa bata mai repede si sa pompeze mai mult sange pentru a compensa situatia si a stabiliza tensiunea arteriala.

In plus, aceste celule determina ingustarea vaselor de sange si astfel, creste tensiunea arteriala. Hipotensiunea ortostatica sau posturala apare atunci cand ceva intrerupe procestul natural al organismului de a contracara scaderea tensiunii arteirala.

Hipotensiunea arteriala ortostatica poate fi cauzata de diferite lucruri inclusiv: deshidratare , varsaturi, diaree , febra, diuretice, medicamente pentru controlul tensiunii arteriale crescute, tulburari cardiovasculare bradicardie , atac de cord , insuficienta cardiaca etc.

Hipotensión Ortostática

Conocimientos recientes sobre la prevalencia, diagnosticos diferenciales, historia natural y los tratamientos farmacologicos y no farmacologicos disponibles Introduccion y objetivos La hipotension ortostatica HO de origen neurogenico es una manifestacion prevalente y discapacitante de la disfuncion autonomica, debida a enfermedades neurodegenerativas. La presentacion de la HO es muy variable, y puede no ser reconocida hasta una etapa avanzada. Los estudios epidemiologicos han mostrado una alta morbimortalidad en asociacion con la HO. Se describen 3 variantes de la HO: HO propiamente dicha HO clasica HO retardada HO inicial La primera se define por la reduccion sostenida de la presion arterial PA en al menos 20 mm Hg de PA sistolica, o al menos 10 mm Hg de PA diastolica, dentro de los 3 minutos de incorporarse desde la posicion de decubito supino o de elevar la cabeza en la prueba de la mesa basculante. La HO puede asociarse con hipertension arterial en posicion supina. La HO retardada se define por una disminucion sostenida de la PA despues de 3 minutos de bipedestacion o de posicion erecta en la mesa basculante. Los pacientes con HO retardada tienden a presentar menos sintomas adrenergicos con la hipotension, lo que sugiere una forma mas leve del trastorno.
