站立位血压稳定调节受损可导致不良结果,包括跌倒、晕厥和定向障碍。平均动脉压(mean arterial pressure,MAP)通常在站立位时增加,然而,站立位MAP增加不足或减少可能导致脑灌注减少。已有研究报道,在动脉硬度增加的老年人中存在体位性低血 Stable blood pressure stabilization can result in poor outcomes, including falls, syncope and disorientation. Mean arterial pressure (MAP) usually increases at standing position, however, insufficient or reduced standing position MAP may result in decreased cerebral perfusion. It has been reported that there is orthostatic hypotension in the elderly with increased arterial stiffness
