The authors examined whether cardiovascular reactivity to and recovery from psychological challenge predict 3-year change in blood pressure (BP) among 216 initially normotensive, community-dwelling adults. Clinic BP assessments were conducted at baseline and follow-up. BP and heart rate (HR) readings were obtained before, during, and after 5 psychological tasks at baseline. Following adjustment for traditional predictors of BP and lifestyle factors, poorer systolic BP recovery across the tasks was associated with greater 3-year increases in clinic systolic and diastolic BP. Both diastolic BP recovery and HR recovery were also related to 3-year change in clinic BP, though cardiovascular reactivity measures were not. These findings suggest that the duration of stress-related cardiovascular responses may be important for predicting longitudinal changes in BP.
作者们研究了216名最初血压正常的社区成年人在面对心理挑战时的心血管反应性以及从该挑战中恢复的情况是否能预测其3年的血压（BP）变化。在基线和随访时进行了诊所血压评估。在基线时，于5项心理任务之前、期间和之后获取血压和心率（HR）读数。在对血压的传统预测因素和生活方式因素进行调整后，在各项任务中收缩压恢复较差与诊所收缩压和舒张压在3年中的更大增幅相关。舒张压恢复和心率恢复也与诊所血压的3年变化有关，不过心血管反应性指标并无此关联。这些发现表明，与压力相关的心血管反应的持续时间对于预测血压的纵向变化可能很重要。
