Orthostatic hypotension affects roughly 10% of individuals with hypertension and is associated with several adverse health outcomes, including dementia, cardiovascular disease, stroke, and death. Among adults with hypertension, orthostatic hypotension has also been shown to predict patterns of blood pressure dysregulation that may not be appreciated in the office setting, including nocturnal nondipping. Individuals with uncontrolled hypertension are at particular risk of orthostatic hypotension and may meet diagnostic criteria for the condition with a smaller relative reduction in blood pressure compared with normotensive individuals. Antihypertensive medications are commonly de-prescribed to address orthostatic hypotension; however, this approach may worsen supine or seated hypertension, which may be an important driver of adverse events in this population. There is significant variability between guidelines for the diagnosis of orthostatic hypotension with regards to timing and position of blood pressure measurements. Clinically relevant orthostatic hypotension may be missed when standing measurements are delayed or when taken after a seated rather than supine position. The treatment of orthostatic hypotension in patients with hypertension poses a significant management challenge for clinicians; however, recent evidence suggests that intensive blood pressure control may reduce the risk of orthostatic hypotension. A detailed characterization of blood pressure variability is essential to tailoring a treatment plan and can be accomplished using both in-office and out-of-office monitoring.
直立性低血压影响约 10%的高血压患者,与多种不良健康结局相关,包括痴呆、心血管疾病、中风和死亡。在高血压成年人中,直立性低血压也可预测血压调节模式,这些模式在诊室环境中可能不被注意到,包括夜间非杓型。血压未得到控制的高血压患者尤其存在直立性低血压的风险,与血压正常的个体相比,血压相对降低较小,可能符合该疾病的诊断标准。抗高血压药物通常用于治疗直立性低血压;然而,这种方法可能会使仰卧位或坐位高血压恶化,这可能是该人群不良事件的一个重要驱动因素。在直立性低血压的诊断指南中,关于血压测量的时间和体位存在显著的差异。当站立测量延迟或采取坐位而不是卧位时,可能会错过临床相关的直立性低血压。高血压患者直立性低血压的治疗对临床医生来说是一个重大的管理挑战;然而,最近的证据表明,强化血压控制可能降低直立性低血压的风险。详细描述血压变异性对于制定治疗计划至关重要,可以通过诊室和诊室外监测来实现。
