【摘要】：目的:探討DTI-Tei指數(shù)在評(píng)價(jià)原發(fā)性高血壓(Primary Hypertension,HP)患者左心室舒張功能的價(jià)值。方法:收集2014年12月至2016年12月在本院門診及住院進(jìn)行心臟超聲檢查的原發(fā)性高血壓(HP)患者84例(A組),選擇年齡、性別相似的健康人群30例作為對(duì)照組(B組),A組按照高血壓心臟不同左心室構(gòu)型分為正常構(gòu)型組(A1組)、向心性重構(gòu)組(A2組)、向心性肥厚組(A3組)、離心性肥厚組(A4組)。利用超聲心動(dòng)圖測(cè)量一般參數(shù):IVST、LVPW、LVEDD、LVMI、RWT;功能參數(shù):E(cm/s)、A(cm/s)、E/A、EDT、Ea/Aa及DTI-Tei指數(shù)。比較分析各組不同參數(shù)的相關(guān)性。結(jié)果:A組與B組間左心室一般參數(shù):IVST、LVPW、LVEDD、LVMI、RWT比較差異均有統(tǒng)計(jì)學(xué)差異(均P0.05);A組與B組間左心室功能參數(shù):E(cm/s)、A(cm/s)、E/A、EDT、Ea/Aa等比較差異均有統(tǒng)計(jì)學(xué)意義(均P0.05);A2組的參數(shù)E/A、EDT與A1、A3、A4組差異有統(tǒng)計(jì)學(xué)意義(均P0.05);A1組參數(shù)Ea/Aa與A2、A3、A4組差異有統(tǒng)計(jì)學(xué)意義(均P0.05);A1組參數(shù)S/D與A2、A3、A4組差異有統(tǒng)計(jì)學(xué)意義(均P0.05);DTI-Tei指數(shù)在A1、A2、A3、A4各組間差異均有統(tǒng)計(jì)學(xué)意義(均P0.05)。結(jié)論:1、DTI-Tei指數(shù)與原發(fā)性高血壓疾病Ganau心臟分型的相關(guān)性良好,隨左心室舒張功能減低有升高趨勢(shì);2、DTI-Tei指數(shù)在對(duì)于左心室舒張功能不全方面優(yōu)于常規(guī)組織多普勒,而常規(guī)組織多普勒又優(yōu)于二尖瓣頻譜多普勒及肺靜脈血流參數(shù);3、DTI-Tei指數(shù)對(duì)于評(píng)價(jià)原發(fā)性高血壓病左心室舒張功能不全方面可以提供可靠的依據(jù)。
[Abstract]:Objective: to evaluate the DTI-Tei index in evaluating primary Hypertension of essential hypertension. The value of left ventricular diastolic function in patients with HP.Methods: from December 2014 to December 2016, we collected essential hypertension patients who were examined by echocardiography in our hospital from December 2014 to December 2016. Group A (84 cases). Thirty healthy persons of similar age and sex were selected as control group. Group A was divided into normal group (A1 group) and concentric remodeling group (A2 group) according to different left ventricular configurations of hypertensive heart. Group A _ 3 and group A _ 4 were used to measure the general parameters of WIVST-LVLVLVVEDDV and LVMIRWT-RWTs by Echocardiography in the concentric hypertrophy group and the centrifugal hypertrophy group respectively, and the results were as follows: (1) Echocardiography was used to measure the general parameters. Functional parameters: 1 / 2 / 2 / 2 / 2 / 2. Results the general parameters of left ventricle between group A and group B were divided into two groups. The difference of RWT was statistically significant (P 0.05). There were significant differences in left ventricular function parameters between group A and group B (P < 0.05). There was significant difference in the parameters of E _ (P _ (P) A) EDT and A _ (1) A _ (3) A _ (4) between A2 group and A _ (1) A _ (3) A _ 4 group (P. The parameters of Ea/Aa in group A1 were significantly different from those in group A _ (2) A _ (3) A _ (3) A _ (4) (P < 0.05). The parameters of group A1 were significantly different from those of group A _ (2) A _ (3) A _ (4) (P < 0.05). There was significant difference in DTI-Tei index between A1A1A2A2A3A4 groups (P 0.05). Conclusion: 1. There was a good correlation between DTI-Tei index and Ganau cardiac typing in essential hypertension, and the left ventricular diastolic function decreased with the increase of left ventricular diastolic function. 2DTI-Tei index was superior to conventional tissue Doppler in the treatment of left ventricular diastolic dysfunction, and conventional tissue Doppler was superior to mitral flow spectrum Doppler and pulmonary vein blood flow parameters. 3 DTI-Tei index can provide reliable evidence for evaluating left ventricular diastolic dysfunction in essential hypertension.
