摘要: |
【】目的:评估组织多普勒(TDI)测定的Tei 指数对血压正常高值患者左心室功能早期改变的临床应用价值。方法:筛选2015年01月至2016年8月我院住院患者作为研究对象,以血压平均水平分组为正常血压组、血压正常高值组、高血压组,符合入选标准者进行心脏超声检测,并应用TDI计算左心室Tei指数。比较各检测指标在各组间的变化情况。结果: 三组间比较Tei 指数差异有显著性(P<0.05),血压正常高值组较正常血压组显著升高(P<0.05),较高血压组低(P<0.05)。血压正常高值组与正常血压组相比,左心室壁厚度及质量指数增加(P<0.05)。结论:Tei指数能更早期的检出心脏总体功能改变情况,对早期监测预防高血压亚临床心功能损害,积极逆转心脏功能具有重要意义。 |

Abstract: |
Objective: Evaluate the clinical application value of Tei index of Tissue Doppler Imaging (TDI) on the early left ventricular function changes of patients with prehypertension.
Methods: Screening patients from January 2015 to August 2016 in Shigatse People’s hospital as research objects. Investigating case history, and having physical examination and blood biochemical examination. The patients were divided into three groups of normotension (NT),prehypertension(Pre-HT)and hypertension(HT). Each group will compare the changes in the indicators.
Results: By comparison, the Tei index difference is significant (P<0.05) in each group. The Tei index difference of patients with prehypertension is significantly higher (P<0.05) than that of patients with normal blood pressure, while significantly lower (P<0.05) than that of patients with high blood pressure. After comparing patients with prehypertension and with normal blood pressure, the increase of index of ventricular wall thickness and quality is significant (P<0.05).
Conclusions: Tei index is able to detect the heart function change at an early stage, and is crucial to early monitoring and prevention of high blood pressure and clinical ventricular function damage, as well as positive reversal of heart function. |
