本文研究了117名越战男性退伍军人（61名患有创伤后应激障碍（PTSD）， 56名没有创伤后应激障碍（PTSD））的日常日记影响评分与动态心血管活动的关系。参与者完成了12-14小时的动态监测和每日日记影响评分。与没有创伤后应激障碍的退伍军人相比，患有创伤后应激障碍的退伍军人在日常日记评分中报告了更高的消极情绪和更低的积极情绪。平均实验室初始记录或平均动态心率（HR）、收缩压（SBP）或舒张压（DBP）均无差异。然而，与没有PTSD的退伍军人相比，PTSD退伍军人在日常活动中表现出更高的SEP和DBP变异性以及更高的HR活动比例（与初始记录值相比）。在一天x时间组中，平均NR有显著的相互作用，PTSD参与者有在夜间维持HR水平的趋势。
The present study investigated the relationship between daily diary affect ratings and ambulatory cardiovascular activity in 117 male Vietnam combat veterans (61 with posttraumatic stress disorder [PTSD] and 56 without PTSD). Participants completed 12-14 hr of ambulatory monitoring and daily diary affect ratings. Compared with veterans without PTSD, veterans with PTSD reported higher negative affect and lower positive affect in daily diary ratings. No differences were detected for mean laboratory initial recordings or mean ambulatory heart rate (HR), systolic blood pressure (SBP), or diastolic blood pressure (DBP). However, compared with veterans without PTSD, veterans with PTSD demonstrated higher SEP and DBP variability and a higher proportion of HR activity (compared with initial recording values) during daily activity. There was a significant Time of Day x Group interaction for mean NR, with a trend for PTSD participants to maintain HR levels during evening hours.
