摘要:
目的: 探讨组织多普勒成像（tissue Doppler imaging,TDI）技术对正常成人左、右心功能的对比评价。方法: 健康成人300例根据年龄分为6组，经胸超声心动图检查，采用心尖四腔切面，应用TDI技术,将取样点置于左室侧壁二尖瓣瓣环处及右室侧壁三尖瓣瓣环处，记录心肌运动速度频谱，测量收缩期峰值（Vs）、舒张早期运动速度峰值（Ve）、舒张晚期运动速度峰值（Va）及Ve/Va比值。结果: 二、三尖瓣环处Ve/Va与年龄呈负相关（r1=-0.946,P<0.01及r2=-0.925,P<0.01）,Vs值与年龄不相关；随着年龄增加，舒张早期Ve逐渐减低，Va逐渐增高，二者比值逐渐出现倒置，尤其三尖瓣瓣环出现更早，50岁左右出现,而二尖瓣环处比值倒置在60岁以后。结论: 随着年龄增长舒张功能逐渐减低，并且右心室舒张功能减低早于左心室，收缩功能与年龄不相关。
Abstract:
AIM: To study left and right ventricular function in healthy adults by tissue Doppler imaging (TDI). METHODS: Three hundred healthy adults were divided into six groups according to age. Systolic and diastolic velocity of mitral and tricuspid annulus were measured in apical 4-chamber views by TDI: peak systolic velocity (Vs), peak early diastolic velocity (Ve), peak late diastolic velocity (Va), and Ve/Va. RESULTS: A negative correlation was observed between Ve/Va and age（r1=-0.946, P<0.01 and r2=-0.925, P<0.01).Vs was not correlated with age. Ve decreased gradually with age, and Va increased gradually with age. Ve/Va of tricuspid annular inverted at ~50 years of age but at ~60 years of age in mitral annulus. CONCLUSION: Diastolic function decreases gradually with age, and right ventricular diastolic function decreases earlier than left ventricular function. Systolic function appears not to be correlated with age.
