经食道心脏超声评价主动脉顺应性

摘要

Aortic distensibility was determined in 46 patients by transesophageal echocardiography.The results showed that aging had good correlations with the increase in internal diameter of the aorta,the decreases if the amplitude of aortic pulse and the compliance fraction and the increase in aortic pressure-strain elastic modulus or pressure-independent stiffness index(r=0.834,-0.834,0.845,0.813,0.866,n=46,P＜0.001,respectively).Hypertension also had reasonable relationships with the aortic compliance parameters described above.In conclusion,we consider that transesaphageal echoeardiography is an ideal method of the direct noninvasive evaluation of the aortic compliance and has cartain clinical values.%以经食道心脏超声技术检测46例患者主动脉顺应性.结果显示,随年龄增高而有相应主动脉内径增宽、主动脉搏动幅度和顺应分数减低、主动脉压力相关牵张强度和非压力相关硬化指数加大(r=0.834,-0.834,-0.845,0.813,0.866,n=46,P<0.001,依次).高血压状态与上述主动脉腰应性参数亦有较好相关性.认为经食道心脏超声检测主动脉顺应性具有一定临床实用价值.
