Tei指数对老年慢性肺源性心脏病患者右心功能的评价

Evaluation on Tei index for right heart function of elderly patients with chronic cor pulmonale

目的探析Tei指数对老年慢性肺源性心脏病患者右心功能的评价作用。方法对本院2009年3月至2012年3月收治的疑似慢性肺源性心脏病老年患者98例(A组)和同期体检健康老年人群68例(B组)进行超声检查和Tei指数测量。超声检查指标有右室内径、右房横径、肺动脉主干内径、右室前壁厚度和肺动脉收缩压(SPAP)。结果 A组患者中31例(31.6%)具有明确的肺心病超声征象,42例(42.9%)患者未见明确肺心病超声征象,但存在三尖瓣和(或)肺动脉瓣反流,27例(25.5%)患者既未见明确肺心病超声征象,又未见三尖瓣或肺动脉瓣反流,三类患者Tei指数均显著高于B组人群(P<0.05)。结论 Tei指数能够反映患者右心功能,可做为评价病情的敏感指标。

Objective To study the evaluation function of Tei index for right heart function of elderly patients with chronic cor pulmonale.Methods Choosed 98 cases of elderly patients suspected chronic cor pulmonale and 68 cases of the medical health elderly population from March 2009 to March 2012 in our hospital as group A and B,ultrasonic inspection and Tei index were measured,ultrasonic inspection indicators contains,right room transverse diameter,the main pulmonary artery diameter,wall thickness and before in pulmonary artery systolic pressure.Results A group of 31 patients（31.6%） with a clear cor pulmonale ultrasonic signs,42 patients（42.9%） did not see clearly cor pulmonale ultrasonic signs,but there was three tricuspid valve and（or） pulmonary valve regurgitation,27 cases（25.5%） patients were not seen clear cor pulmonale ultrasonic signs,and did not see the tricuspid valve and pulmonary valve regurgitation,three types of Tei index patients were significantly higher than the group B（P0.05）.Conclusion Tei index can reflect patients right heart function and can be used as a sensitive index evaluation.
