无创心功能检查对妊娠期高血压诊断价值

Diagnostic value of noninvasive cardiac function measurement for pregnancy-induced hypertension

目的 探讨无创心功能检查对妊娠期高血压的诊断价值。方法 应用无创心功能检测仪观察128例妊娠期高血压患者(轻症组、重症组)的心肌力能参数(左室喷血压JP、左室有效泵力VP)、心阻抗参数(总阻抗RTM、动脉特性阻抗RS)、容量负荷参数(有效循环容量GCV、左室舒张末期压力LVDP)、左心排参数(左心排指数LCI)等反映心功能的参数,设30例健康孕妇为对照组。结果 轻症组、重症组心肌力能参数、心阻抗参数、左心排参数异常增高,与对照组比较有显著性差异(P<0.05);重症组容量负荷参数异常增高,与对照组比较有显著性差异(P<0.05)。结论 应用无创心功能心肌力能参数、心阻抗参数、左心排参数对妊娠期高血压有较大诊断价值,且简单、快捷。

Objective To explore the diagnostic value of noninvasive cardiac function measurement for pregnancy induced hypertension. Methods 128 cases of gestational hypertension treated in our hospital were analyzed retrospectively while 30 healthy pregnant women were served as normal controls.The heart function parameters in two groups were measured by noninvasive cardiac function analyzer,such as myocardial contractive force indexes(JP,VP),impedance indexes(RTM,RS),volume load indexes(GCV,LVDP) and left heart output index(LCI). Results In all 128 cases of gestational hypertension,the myocardial contractive force indexes,impedance indexes and left heart output index increased unusually,the difference between the two groups was statistically significant, P <0.05.The myocardial contractive force indexes and the impedance indexes increased significantly higher than left heart output index, P <0.05. Conclusion The noninvasive cardiac function measurement has much valuable in the early diagnosis of pregnancy induced hypertension,especially the myocardial contractive force indexes,impedance indexes and left heart output index,it appeared to be simple,efficient and worthy to be clinically popularized and applied.
