Nocturnal blood pressure (BP) dipping is a risk factor for cardiovascular disease, independent of nighttime BP levels. We compared nocturnal BP dipping detected by conventional ambulatory BP monitoring (ABPM) with that detected by nocturnal home BP monitoring (HBPM), which can measure BP during sleep with a timer function. We analyzed data of 927 subjects in the nationwide practice-based J-HOP Nocturnal BP Study and observed that the prevalences of nocturnal BP dipping status for HBPM and ABPM respectively were: extreme dipper, 6.9% and 14.8%; dipper, 36.1% and 42.4%; non-dipper, 42.8% and 33.2%; riser pattern, 14.1%, and 9.6%. The agreement between nocturnal dipping classification by HBPM and ABPM was 41.0%, and when we used ≥3 days of HBPM data, the agreement rate increased to 42.8%. Obtaining an increased number of nighttime BP measurements at home for multiple days may increase the reliability of assessments of nocturnal BP dipping status detected by HBPM.
夜间血压下降是心血管疾病的一个危险因素，与夜间血压水平无关。我们比较了通过传统动态血压监测（ABPM）检测到的夜间血压下降情况与通过夜间家庭血压监测（HBPM）检测到的情况，后者可通过定时器功能在睡眠期间测量血压。我们分析了全国性基于实践的J-HOP夜间血压研究中927名受试者的数据，观察到HBPM和ABPM的夜间血压下降状态患病率分别为：极度杓型，6.9%和14.8%；杓型，36.1%和42.4%；非杓型，42.8%和33.2%；反杓型，14.1%和9.6%。HBPM和ABPM对夜间血压下降分类的一致性为41.0%，当我们使用≥3天的HBPM数据时，一致率提高到42.8%。在家中连续多天增加夜间血压测量次数可能会提高通过HBPM检测到的夜间血压下降状态评估的可靠性。
