摘 要: | 目的探讨组织多普勒成像(TDI)技术评价老年高血压患者右心室功能的临床价值。方法选择老年高血压患者34例(高血压组)和健康老年人44例(对照组)。经胸超声心动图检查,应用TDI技术于心尖四腔观获取右心室侧壁三尖瓣环处心肌运动频谱图,测量舒张早期峰值速度(Em)、舒张晚期峰值速度(Am),并计算Em和Am比值。同时测量收缩期峰值速度(Sm)、等容收缩期心肌加速度。结果高血压组Em(5.91±1.56)cm/s、Am(12.79±2.63)cm/s、Sm(10.82±1.45)cm/s均明显低于对照组Em(7.57±2.11)cm/s、Am(14.27±2.03)cm/s、Sm(12.68±2.33)cm/s,差异有统计学意义(P=0.000,P=0.006,P=0.000);Em/Am高血压组(0.47±0.12)明显低于对照组(0.54±0.15),差异有统计学意义(P=0.048)。结论 TDI可以准确、直观地评价老年高血压患者右心室功能。

Abstract: | Objective To investigate the tissue Doppler imaging(TDI) in evaluating the function of right ventricle in elderly patients with hypertension.Methods Thirty-four elderly patients with hypertension and 44 healthy individuals as control group were enrolled in the study.The frequency spectrogram of tricuspid annular motion was obtained by pulse-wave Doppler tissue imaging. The peak systolic velocity(Sm),the peak velocity at early diastole(Em) and at late diastole(Am) were measured.The ratio of Em/Am was calculated and the myocardial acceleration during isovolumic contraction was measured.Results The Em(5.91±1.56) cm/s,Am(12.79±2.63) cm/s and Sm(10.82±1.45) cm/s in hypertension group were significantly lower than those in the control group[Em(7.57±2.11) cm/s,Am(14.27±2.03) cm/s and Sm(12.68±2.33) cm/s](P = 0.000,P =0.006,P =0.000).The ratio of Em/Am(0.47±0.12)in hypertension patients was significantly lower than that(0.54±0.15) in the control group(P =0.048).Conclusions TDI can accurately and directly assess the function of right ventricle in elderly patients with hypertension. |
