夜间血压（BP）下降不足与脑血管疾病有关。作者旨在确定夜间浸渍不足是否与无卒中个体的脑血管血流动力学异常相关。这项研究的参与者进行了24小时动态血压监测，然后在仰卧位休息、头高位倾斜、低碳酸血症和高碳酸血症期间进行了大脑中动脉血流速度（BFV）的早晨经颅多普勒测量。夜间BP下降
Inadequate dipping in nighttime blood pressure (BP) is associated with cerebrovascular disease. The authors aimed to determine whether inadequate nocturnal dipping was associated with abnormalities in cerebrovascular hemodynamics in individuals without stroke. Participants in this study underwent 24-hour ambulatory BP monitoring followed by morning transcranial Doppler measurements of blood flow velocities (BFVs) in the middle cerebral artery during supine rest, head-up tilt, hypocapnia, and hypercapnia. Nighttime BP decline by
