Orthostasis or drop in blood pressure during upright posture, is a product of the activity of the gravitational force on the cardiovascular system, which if the cardiovascular system is not able to compensate will cause loss of consciousness, or syncope In some people by which, because of different pathological condition, the cardiovascular system is not able to maintain a normal blood pressure during upright posture, and leads to syncope. Postural hypotension in the elderly age group, reduces cerebral blood flow and carries considerable morbidity from dizziness, falls and injury. In acute stroke, cerebral perfusion is dependent on systemic blood pressure because cerebrovascular autoregulation is impaired. Thus, postural hypotension in acute stroke patients may further impair cerebral blood flow, increase stroke risk, or hinder recovery. | |
