Objective To investigate the correlation of instantaneous accelerating wave intensity W1 of carotid artery with the carotid elasticity parameter of anti-seismic soldiers.Methods The wave intensity(WI) and related ultrasound indexes of 100 anti-seismic soldiers acutely exposuring to plateau within seven days and 100 healthy soldiers living on the plains were detected by Prosound αl0 color Doppler ultrasonography manufactured by company of ALOKA.The indexes were analyzed by spearman relevant analysis with statistical package SPSS 18.0.Results ①Compared with the control group,instantaneous accelerating wave intensity W1,arterial compliance(AC),argumentation index (AI) of the high altitude group were lower,pressure-strain elastic modulus(Ep),stiffness parameter(β) were higher,but there was no significant difference between the two groups ( P all ＞ 0.05).Pulse wave velocity (PWV-WI) was higher (P ＜ 0.05 ).②Sperman relevant analysis results showed:W1 was positively correlated with PWV-WI,and was negatively correlated with AI,but has no statistical relationship with Ep,β and AC.Conclusions Among the indexes reflecting carotid artery elasticity,pulse wave velocity is a sensitive index of acute high altitude hypoxia reaction,and vessel parameters can reflect the cardiac function.%目的 探讨抗震官兵颈动脉瞬时加速度波强W1与颈动脉弹性参数间的相关性.方法 应用ALOKA公司ProSound α-10彩色多普勒超声诊断仪对100例平原官兵及100例急进高原7d内的抗震官兵进行瞬时波强(WI)及相关超声指标的检测,应用软件包SPSS 18.0对各检测指标进行Spearman相关分析.结果 ①与对照组比较,高原组瞬时加速度波强W1、动脉顺应性(AC)减低、脉搏波反射增强(AI)减低,压力-应变弹性系数(EP)增高、硬化参数(β)增高,但差异均无统计学意义,脉搏波传导速度(PWV-WI)增高(P＜0.05).②Spearman相关分析结果显示:W1与PWV-WI呈正相关,与AI呈负相关,与Ep、β、AC无显著相关性.结论 在反映颈动脉弹性功能的指标中,PWV-WI是急进高原缺氧反应的敏感指标,且通过血管参数可反映心脏的功能情况.
