在心血管病的发病率逐年上升的趋势下,临床上如何早期诊断患者心功能异常,评价治疗效果和判断预后具有重要意义。传统的心室舒缩功能指标都基于对心室几何形态的假设,并在不同程度上受超声透声条件、心率及心脏前后负荷变化的影响,其应用价值尚存在一些争论,近期发展起来的Tei指数能综合评价心脏舒缩功能,弥补了前者不足,Tei指数的应用和完善将对临床心功能的评价更具有指导意义。
In the incidence of cardiovascular disease increased year by year trend, how to diagnose early in patients with cardiac dysfunction, evaluation of treatment and prognosis of great significance. Traditional ventricular systolic and diastolic function indexes are based on the hypothesis of ventricular geometry, and to varying degrees, by the sound and sound conditions of ultrasound, heart rate and heart load changes before and after the impact of its application value there are still some controversy, the recent development of the Tei index Can comprehensively evaluate the cardiac systolic and diastolic function, make up the lack of the former, the application and improvement of the Tei index will be more instructive in the evaluation of clinical cardiac function.
