The relationship between 24-hour ambulatory blood pressures (ABP) and blood pressures (BP) obtained during laboratory stressors was examined. Thirty normotensives (equal males and females) underwent ABP monitoring on three occasions separated by a week. They also underwent a laboratory assessment which included standard stressors (i.e., mental arithmetic, cold pressor, orthostatic response, treadmill exercise). Correlational analyses found laboratory pressures to be significantly correlated with ambulatory pressures, with laboratory baseline BPs showing higher correlations to the ambulatory BPs than the BPs obtained during laboratory stressors. In addition, gender effects were examined. In the correlational analyses between ABPs and laboratory BPs, males and females did not differ significantly in the strength of the correlations. In terms of absolute values, males were found to have significantly higher SBP during ambulatory monitoring, random-zero recordings, calibration readings, and during baselines of the laboratory assessment. There were no gender effects for these measures with respect to diastolic blood pressure or heart rate. There were also no gender effects on reactivity to laboratory stressors as measured by change scores. Exploratory analyses found no significant effect of history of familial hypertension on either the ABPs or the laboratory pressures.
研究了24小时动态血压(ABP)与实验室应激源期间测得的血压(BP)之间的关系。30名血压正常者(男女各半)分三次进行ABP监测,每次间隔一周。他们还接受了一项实验室评估,其中包括标准应激源(即心算、冷加压、直立反应、跑步机运动)。相关性分析发现,实验室血压与动态血压显著相关,实验室基线BP与动态BP的相关性高于实验室应激源期间测得的BP。此外,还研究了性别效应。在ABP与实验室BP的相关性分析中,男性和女性在相关性强度上没有显著差异。就绝对值而言,发现男性在动态监测、随机零点记录、校准读数以及实验室评估基线期间的收缩压显著更高。这些测量在舒张压或心率方面没有性别效应。通过变化分数衡量,在对实验室应激源的反应性方面也没有性别效应。探索性分析发现,家族性高血压病史对ABP或实验室血压均无显著影响。
