Hyperarousal is a hallmark of posttraumatic stress disorder (PTSD). PTSD has been associated with increased blood pressure (BP) and heart rate (HR) in veteran populations. We retrospectively identified male patients consulted to outpatient psychiatry at the Iowa City Veterans Affairs Healthcare System. Patients were divided into PTSD (n = 88) and non-PTSD (n = 98) groups. All PTSD patients and a subset of non-PTSD patients had documented blast exposure during service. The study investigated whether patients with PTSD had higher systolic blood pressure (SBP), diastolic blood pressure (DBP), and heart rate (HR) than patients without PTSD. The effect of trauma exposure on BP was also examined. Mean SBP (133.8 vs. 122.3 mm Hg; p < .001), DBP (87.6 vs. 78.6 mm Hg; p < .001), and HR (78.9 vs. 73.1 bpm; p < .001) were all significantly higher in the PTSD group. Trauma-exposed patients without PTSD had significantly higher BP than nonexposed patients. The prevalence of hypertension (HTN) was 34.1% (diagnosed and undiagnosed) among PTSD patients. Patients with PTSD had higher BP and HR compared to patients without PTSD. Trauma exposure may increase BP in this population. These findings will increase awareness about the cardiovascular implications of PTSD.

標題:創傷後壓力症對退役軍人血壓和心跳的影響

撮要:過度警覺是創傷後壓力症(PTSD)的特徵。在退役軍人中,PTSD與血壓(BP)高和心跳(HR)快有關連。本硏究回顧了愛荷華市退役軍人醫療系統中精神科門診的男性求診人士,其中有PTSD病者及一部份非PTSD病者均在服役時有爆炸經歷。本文旨在硏究PTSD患者會否比非PTSD患者有較高收縮期血壓(SBP),舒張期血壓(DBP)及心跳(HR)。創傷經歷對血壓的影響也在硏究之列。PTSD組別都有統計上明顯較高的平均SBP(133.8 vs 122.3mmHg; P<.0001),DBP(87.6 vs 78.6mmHg; P<.0001)和HR(78.9 vs 73.1bpm; P<.0001)。非PTSD病人中,曾經歷創傷者有統計上明顯較高BP。PTSD病人中的高血壓(HTN)患病率是34.1%(診斷及未診斷者)。PTSD病人對比非PTSD病人有更高的BP和HR。創傷經歷可導致PTSD的退役軍人有血壓增高的情況。這些發現增進我們了解PTSD的心血管狀況。

撮要:过度警觉是创伤后压力症(PTSD)的特征。在退役军人中,PTSD与血压(BP)高和心跳(HR)快有关系。本硏究回顾了爱荷华市退役军人医疗系统中精神科门诊的男性求诊人士,其中有PTSD病者及一部份非PTSD病者均在服役时经历爆炸。本文旨在硏究PTSD患者会否比非PTSD患者有较高收缩期血压(SBP),舒张期血压(DBP)及心跳(HR)。创伤经历对血压的影响也在硏究之内。PTSD组别都有统计上明显较高的平均SBP(133.8 vs 122.3mmHg; P<.0001),DBP(87.6 vs 78.6mmHg; P<.0001)和HR(78.9 vs 73.1bpm; P<.0001)。非PTSD病人中,曾经历创伤者有统计上明显较高BP。PTSD病人中的高血压(HTN)患病率是34.1%(诊断及未诊断者)。PTSD病人对比非PTSD病人有更高的BP和HR。创伤经历可导致PTSD的退役军人有血压增高的情况。这些发现增进我们了解PTSD的心血管状况。
