This study investigated the role of acute arousal in the development of posttraumatic stress disorder (PTSD). Hospitalized motor-vehicle-accident survivors (n = 146) were assessed for acute stress disorder (ASD) within 1 month of the trauma and were reassessed (n = 113) for PTSD 6 months posttrauma. Heart rate (HR) and blood pressure (BP) were assessed on the day of hospital discharge. Participants with subclinical ASD had higher HR than those with ASD and no ASD. Participants who developed PTSD had higher HR in the acute posttrauma phase than those without PTSD. Diagnosis of ASD and resting HR accounted for 36% of the variance of the number of PTSD symptoms. A formula composed of a diagnosis of ASD or a resting HR of > 90 beats per minute possessed strong sensitivity (88%) and specificity (85%) in predicting PTSD. These findings are discussed in terms of acute arousal and longer term adaptation to trauma.
本研究调查了急性唤醒在创伤后应激障碍（PTSD）发展中的作用。对因机动车事故住院的幸存者（n = 146）在创伤后1个月内进行急性应激障碍（ASD）评估，并在创伤后6个月对其中113人进行PTSD重新评估。出院当天测量心率（HR）和血压（BP）。亚临床ASD参与者的心率高于患有ASD和无ASD的参与者。发生PTSD的参与者在创伤后急性期的心率高于未患PTSD的参与者。ASD诊断和静息心率占PTSD症状数量变异的36%。由ASD诊断或静息心率>90次/分钟组成的公式在预测PTSD方面具有较高的敏感性（88%）和特异性（85%）。从急性唤醒和对创伤的长期适应角度对这些发现进行了讨论。
