用44例原发性高血压(EH)患者及15例健康人对照组(N)的平衡法心血池显像(MGBP)心功能参数,对比分析了EH组多普勒超声心动图(UCG)及心机械图(MCG)的心脏检测指标.结果示,MGBP检测中 EH 组的左室高峰充盈率(PFR)、右室射血分数(RVEF)、局部射血分数_4(EF_4)及局部轴缩短率_4(RS_4)明显低于对照组(P<0.05～0.01).反映左室舒张功能的PFR与E/A峰比值(UCG)之间呈正相关(r=0.44,P<0.05),PFR与a/Eo(MCG)之间呈负相关(r=-0.87 P<0.01),PFR与左房内径(UCG)之间呈负相关(r=-0.48 P<0.05),反映左室间隔部位改变的EF_4,RS_4与室间隔厚度(UCG)均呈负相关(r=-0.3 P<0.05,;γ=-0.47 P<0.05).
The heart function parameters of 44 patients with essential hypertension (EH) and 15 healthy controls (N) were compared by the method of equilibrium blood flow imaging (MGBP) to compare the EH group Doppler echocardiography (UCG) And cardiac mechanical map (MCG) were detected in the heart of the EGB group.Results showed that in the MGBP group, the left ventricular peak filling rate (PFR), right ventricular ejection fraction (RVEF), local ejection fraction (EF_4) Axial shortening rate (RS_4) was significantly lower than that of the control group (P <0.05 ~ 0.01) .The PFR reflecting the left ventricular diastolic function positively correlated with the E / A peak ratio (UCG) (r = 0.44, , Negative correlation between PFR and a / Eo (MCG) (r = -0.87 P <0.01) and negative correlation between PFR and left atrium diameter (UCG) (r = -0.48 P < The changes of EF4, RS4 and interventricular septum thickness (UCG) were negatively correlated (r = -0.3 P <0.05, γ = -0.47 P <0.05).
