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, 6 months later, and reassessed for PTSD 2 years posttrauma (n = 87). Heart rates (HR) were assessed on the day of hospital discharge. Participants who had PTSD 2 years posttrauma had higher HR at hospital discharge than those without PTSD. A diagnosis of ASD or a resting HR of 95 beats per minute had moderate sensitivity (74%) and specificity (91%) in predicting PTSD. These findings suggest that caution is required in using acute HR as a predictor of longer-term PTSD following 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，6个月后再次评估，并在创伤后2年对PTSD进行重新评估（n = 87）。在出院当天评估心率（HR）。创伤后2年患有PTSD的参与者出院时的心率高于未患PTSD的参与者。ASD诊断或静息心率为每分钟95次在预测PTSD方面具有中等敏感性（74%）和特异性（91%）。这些发现表明，在将急性心率作为创伤后长期PTSD的预测指标时需谨慎。
