Extreme cardiovascular reactions to psychological stress have been associated with traumatic life experiences. Previous studies have focused on the occurrence or frequency of abuse rather than type of abuse. We examined how occurrence, frequency, and the type of abuse history are related to cardiovascular reactivity (CVR) to acute psychological stress.
The study consisted of between group and continuous analyses to examine the association between occurrence, type, and frequency of abuse with cardiovascular reactions to acute psychological stress.
Data from 64 participants were collected. Heart rate, systolic blood pressure, and diastolic blood pressure were measured at baseline and during a standard mental arithmetic stress task.
Individuals who experienced abuse showed diminished CVR to acute psychological stress; this was driven specifically by the history of sexual abuse. Frequency of abuse did not relate to stress reactions.
These findings accord with previous work suggesting a relationship between traumatic life experience and hypoarousal in physiological reactivity and extend previous findings by suggesting the relationship may be driven by sexual abuse.
对心理压力产生的极端心血管反应与创伤性生活经历有关。以往的研究主要关注虐待行为的发生或频率，而非虐待类型。我们研究了虐待史的发生、频率和类型与急性心理压力下心血管反应性（CVR）之间的关系。
本研究包括组间分析和连续分析，以检验虐待的发生、类型和频率与急性心理压力下心血管反应之间的关联。
收集了64名参与者的数据。在基线和标准心算应激任务期间测量心率、收缩压和舒张压。
经历过虐待的个体对急性心理压力的心血管反应性降低；这一现象尤其由性虐待史导致。虐待频率与应激反应无关。
这些发现与之前表明创伤性生活经历与生理反应性唤醒不足之间存在关联的研究结果一致，并通过表明这种关系可能由性虐待导致，扩展了之前的研究结果。
