目的:应用二维斑点追踪技术(2D-STI)评价高血压患者(HT)左房功能。方法选取北京军区总医院心内科2007年5月至2012年8月门诊及住院二维超声心动图图像清晰的原发性高血压患者85例,男性44例,女性41例,年龄36~68岁,平均年龄(53.7±9.6)岁。根据左室质量指数(LVMI)将原发性高血压患者分LVN组(46例)和LVH组(39例)。选择同期30例健康体检者为对照组。常规超声心动图检测左室舒张末期内径(LVEDd)、室间隔厚度(IVST)、左室后壁厚度(PWT)、E/A比值和左房最大容积(LAVmax),左房最小容积(LAVmin),计算左室心肌质量、左室心肌质量指数(LVMI),左房容积指数(LAVI)和左房总排空分数(LATEF)。应用STI获取左房纵向应变曲线,记录房壁各节段收缩期峰值应变及应变率(SSL、SRs)、舒张早期峰值应变率(SRe)、舒张晚期峰值应变率(SRa),计算其平均值(m)。结果与对照组和LVN组比较,LVH组LAVI升高,分别为[(22.8±7.3)ml/m2 vs.(32.6±6.1)ml/m2]和[(26.7±6.2)ml/m2 vs.(32.6±6.1)ml/m2],差异有统计学意义(P均<0.05)。LVH组较LVN组LVMI [(135.3±18.7)g/m2 vs.(98.9±13.8)g/m2]升高,差异有统计学意义(P<0.05)。与对照组比较,LVN组mSRs[(1.6±0.5)/s vs.(1.8±0.6)/s]升高,LVH组mSRs[(1.6±0.5)/s vs.(1.0±0.4)/s]降低,LVN组和LVH组mSRe均降低,分别为[(-1.9±0.5)/s vs.(-1.4±0.4)/s]和[(-1.9±0.5)/s vs.(-0.9±0.4)/s],mSRa均升高,分别为[(-1.3±0.4)/s vs.(-1.7±0.5)/s]和[(-1.3±0.4)/s vs.(-2.0±0.5)/s],差异有统计学意义(P均<0.05)。与LVN组比较,LVH组mSRs[(1.8±0.6)/s vs.(1.0±0.4)/s]、mSRe [(-1.4±0.4)/s vs.(-0.9±0.4)/s]降低,mSRa[(-1.7±0.5)/s vs.(-2.0±0.5)/s]升高,差异有统计学意义(P均<0.05)。结论高血压患者左房的管道功能下降,辅泵功能增加,左室肥厚患者左房的储备功能下降。STI能无创及定量评价高血压患者左房整体的功能异常。

Objective To review the left atrial function by using two-dimension strain-speckle tracking imaging (2D-STI) in patients with hypertension. Methods The patients [n=85, male 44, female 41, aged from 36 to 68 and average age=(53.7±9.6)] were chosen from May 2007 to Aug. 2012, and divided into LVN group (n=45) and LVH group (n=39) according to left ventricular mass index (LVMI). Other 30 cases with physical examinations were chosen as control group. The routine echocardiogram was used for detecting LVEDd, IVST, PWT, E/A, LAVmax and LAVmin, and calculating left myocardial mass, LVMI, LAVI and LATEF. 2D-STI was used for obtaining longitudinal strain curve of left atrium, recording peak strain and strain rate of different segment systolic phases of atrial wall (SSL and SRs), SRe and Sra, and calculating the mean (m). Results Compared with control group and LVN group, LAVI increased in LVH group [(22.8±7.3) ml/m2 vs. (32.6±6.1) ml/m2] and [(26.7±6.2) ml/m2 vs. (32.6±6.1) ml/m2, all P<0.05]. Compared with LVN group, LVMI [(135.3±18.7) g/m2 vs. (98.9±13.8) g/m2] increased in LVH group (P<0.05). Compared with control group, mSRs [(1.6±0.5)/s vs. (1.8±0.6)/s] increased in LVN group [(1.6±0.5)/s vs. (1.8±0.6)/s], and decreased in LVH group [(1.6±0.5)/s vs. (1.0±0.4)/s], mSRe decreased in LVN group [(-1.9± 0.5)/s vs. (-1.4±0.4)/s] and LVH group [(-1.9±0.5)/s vs. (-0.9±0.4)/s], and mSRa increased in LVN group [(-1.3 ±0.4)/s vs. (-1.7±0.5)/s] and LVH group [(-1.3±0.4)/s vs. (-2.0±0.5)/s, all P<0.05]. Compared with LVN group, mSRs [(1.8±0.6)/s vs. (1.0±0.4)/s] and mSRe [(-1.4±0.4)/s vs. (-0.9±0.4)/s] decreased, and mSRa [(-1.7±0.5)/s vs. (-2.0±0.5)/s] increased in LVH group (all P<0.05). Conclusion The patients with hypertension have decreased left atrial piping function and increased sub-pumping function, and those with left atrial hypertrophy have decreased left atrial conserving function. STI can quantitatively review the integrate function of left atrium without invasion in patients with hypertension.
