【摘要】 本文采用超声心动图法对７５例高血压病患者的主动脉输入阻抗（ＡＩＩ）和左室肥厚及其类型的关系进行研究，结果显示：（１）室壁肥厚组（包括对称和不对称肥厚）表现ＡＩＩ增高，而左室扩张组ＡＩＩ正常．（２）左室肥厚而无扩张时，ＡＩＩ与左室收缩末期室壁应力（ＥＳＳ）呈显著正相关（γ＝０．７６，ｐ＜０．０１）．（３）经有效地降压治疗后，ＡＩＩ降低与左室重量（ＬＶＭ）减轻呈平行关系，这提示在高血压病中，ＡＩＩ对左室肥厚的发生、维持和结构重建过程中发挥重要作用．更多还原

【Abstract】 This study is to observe the changes of aortic input impedance(AII)in 75 hypertensivepatients with different patterns of left ventricular hypertrophy(LVH)by echocardiography,Theresults showed that:(1)AII in concentric hypertrophy(CH)and asymmentric septal hypertrophy(ASH)group was significantly group higher than that in diastolic left ventricular dimension(DH)group.(2)AIl was significantly potensive to end systolic left ventricular stress(ESS)in CH andASH group( r=0. 76,P<0.01).(3)After treatment,significant regression of LVH Was associ-ated with decreasing AII.It suggested that AII might play an important role in the development ofLVH and in the remolding of left ventricular structure.更多还原
