【摘要】：目的:探讨DTI-Tei指数在评价原发性高血压(Primary Hypertension,HP)患者左心室舒张功能的价值。方法:收集2014年12月至2016年12月在本院门诊及住院进行心脏超声检查的原发性高血压(HP)患者84例(A组),选择年龄、性别相似的健康人群30例作为对照组(B组),A组按照高血压心脏不同左心室构型分为正常构型组(A1组)、向心性重构组(A2组)、向心性肥厚组(A3组)、离心性肥厚组(A4组)。利用超声心动图测量一般参数:IVST、LVPW、LVEDD、LVMI、RWT;功能参数:E(cm/s)、A(cm/s)、E/A、EDT、Ea/Aa及DTI-Tei指数。比较分析各组不同参数的相关性。结果:A组与B组间左心室一般参数:IVST、LVPW、LVEDD、LVMI、RWT比较差异均有统计学差异(均P0.05);A组与B组间左心室功能参数:E(cm/s)、A(cm/s)、E/A、EDT、Ea/Aa等比较差异均有统计学意义(均P0.05);A2组的参数E/A、EDT与A1、A3、A4组差异有统计学意义(均P0.05);A1组参数Ea/Aa与A2、A3、A4组差异有统计学意义(均P0.05);A1组参数S/D与A2、A3、A4组差异有统计学意义(均P0.05);DTI-Tei指数在A1、A2、A3、A4各组间差异均有统计学意义(均P0.05)。结论:1、DTI-Tei指数与原发性高血压疾病Ganau心脏分型的相关性良好,随左心室舒张功能减低有升高趋势;2、DTI-Tei指数在对于左心室舒张功能不全方面优于常规组织多普勒,而常规组织多普勒又优于二尖瓣频谱多普勒及肺静脉血流参数;3、DTI-Tei指数对于评价原发性高血压病左心室舒张功能不全方面可以提供可靠的依据。
[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.
