摘要
目的探讨瞬时波强(WI)技术评价慢性肾功能衰竭(CRF)与原发性高血压(HTN)患者心功能改变的价值。方法选择30例CRF患者(CRF组)、HTN患者30例(HTN组)及35例健康查体者(对照组),分别采用WI技术检测心血管功能。结果EF值CRF组<HTN组<对照组(P<0.05);僵硬度(β)、压力应变弹性模量(Ep)、单点脉搏波传导速度(PWVI)、WI脉搏波传导速度(PWVWI)在CRF组与HTN组均明显高于对照组(P<0.05);瞬时加速度波强(W1)、瞬时减速度波强(W2)、瞬时波强负向波面积(NA)在CRF组明显高于HTN组和对照组(P<0.05)。结论WI技术可早期综合评价CRF和HTN患者心血管功能,对预防临床心血管系统并发症有重要价值。
Objective To investigate the value of wave intensity(WI) technique in evaluating changes of heart function in patients with chronic renal failure(CRF) and primary hypertension (HTN).Methods Thirty patients with CRF(CRF group),30 patients with HTN(HIN group) and 35 normal subjects (control group) were collected,and cardiovascular function of which were examined respectively by WI technique. Results Ejection Fraction (EF) in the CRF group <HTN group <control group(P<0.05). The data of stiffness parameter(β),strain elastic modulus(Ep),one-point pulse wave velocity (PWVI) and PWVWI in CRF group and HTN group were higher than those in the control group(P<0.05).The data of instantaneous acceleration wave intensity(W1),instantaneous deceleration wave intensity(W2),Negative Area (NA) in CRF group were higher than those in the HTN group and control group(P<0.05). Conclusions WI technique can evaluate the cardiovascular function of the patients with CRF and HTN earlier and synthetically. And it may be helpful to prevent the complications of cardiovascular disease.
