Blunted blood pressure (BP) dipping during nighttime sleep has been associated with an increased risk of cardiovascular events. Psychological traits have been associated with prolonged cardiovascular activation and a lack of cardiovascular recovery. This activation may extend into nighttime sleep and reduce BP dipping.
This study aims to evaluate the association between trait rumination and nighttime BP dipping.
Sixty women scoring either high or low on trait rumination underwent one 24-h ambulatory BP monitoring session. Self-reported wake and sleep times were used to calculate nighttime BP.
High trait rumination was associated with less diastolic blood pressure (DBP) dipping relative to low trait rumination. Awake ambulatory BP, asleep systolic blood pressure (SBP) and DBP, and asleep SBP dipping were not associated with trait rumination.
In a sample of young women, high trait rumination was associated with less DBP dipping, suggesting that it may be associated with prolonged cardiovascular activation that extends into nighttime sleep, blunting BP dipping.
夜间睡眠期间血压(BP)下降不明显与心血管事件风险增加有关。心理特质与心血管系统长期激活及缺乏心血管恢复有关。这种激活可能会持续到夜间睡眠并减少血压下降。
本研究旨在评估特质性沉思与夜间血压下降之间的关联。
60名在特质性沉思方面得分高或低的女性接受了一次24小时动态血压监测。通过自我报告的清醒和睡眠时间来计算夜间血压。
相对于低特质性沉思,高特质性沉思与舒张压(DBP)下降较少有关。清醒时动态血压、睡眠时收缩压(SBP)和DBP以及睡眠时SBP下降与特质性沉思无关。
在年轻女性样本中,高特质性沉思与较少的DBP下降有关,这表明它可能与持续到夜间睡眠的心血管系统长期激活有关,从而减弱血压下降。
