除了心血管反应性的构建，心血管从压力中恢复的测量代表了夸大的生理唤醒和疾病风险的重要指标。创伤后应激障碍（PTSD）的心血管恢复尚未得到足够的重视。本研究探讨了是否心血管恢复后的口头讲话的压力与创伤后应激障碍症状的严重程度，以及是否认知压力评估的威胁和挑战与创伤后应激障碍的严重程度和恢复显着相关。样本包括50名暴露于创伤的平民妇女，年龄从19岁到49岁不等（M = 30.9，SD = 7.8）。采用结构化访谈法对创伤后应激障碍严重程度进行量化分析。在两个任务后时间点评估心血管恢复，以恢复至基线的百分比表示;恢复措施包括阻抗心动图导出的心输出量（CO）和总外周阻力（TPR）、心率和血压。总体PTSD严重程度与较少的CO恢复相关，r =-0.39，p = 0.006;这种效应在PTSD症状类别中相似，显著相关性范围为r =-0.30到r =-0.44。然而，只有回避组中的PTSD严重程度与TPR恢复较少相关，r =-0.29，p = 0.047。创伤后应激障碍的严重程度与更大的威胁评估相关，r = 0.30，p = 0.035，更大的威胁评估与更少的CO恢复相关，r =-0.33，p = 0.019。结果部分支持的理论，更大的创伤后应激障碍的严重程度和认知评估的威胁，有助于减少心血管疾病的恢复时，面对一个压力诱导的情况。
Beyond the construct of cardiovascular reactivity, the measurement of cardiovascular recovery from stress represents an important index of exaggerated physiological arousal and disease risk. Cardiovascular recovery in posttraumatic stress disorder (PTSD) has not received adequate attention. The present study examined whether cardiovascular recovery following an oral speaking stressor was associated with the severity of PTSD symptoms, and whether cognitive stress appraisals of threat and challenge were significantly associated with PTSD severity and recovery. The sample consisted of 50 trauma-exposed civilian women ranging from 19 to 49 years of age (M = 30.9, SD = 7.8). The PTSD severity indices were quantified based on structured interview. Cardiovascular recovery was assessed at two posttask time points as percentage return to baseline; the recovery measures consisted of impedance cardiography-derived cardiac output (CO) and total peripheral resistance (TPR), heart rate and blood pressure. Total PTSD severity was associated with less CO recovery, r = −.39, p = .006; this effect was similar across PTSD symptom categories, with significant correlations ranging from r = −.30 to r = −.44. However, only PTSD severity in the avoidance cluster was associated with less TPR recovery, r = −.29, p = .047. Total PTSD severity was associated with greater threat appraisal, r = .30, p = .035, and greater threat appraisal was associated with less CO recovery, r = −.33, p = .019. Results partially support the theory that greater PTSD severity and cognitive appraisals of threat contribute to less cardiovascular recovery when confronted with a stress-inducing situation.
