应用彩色多普勒超声探讨主动脉瓣返流与年龄的关系

本文报告经彩色多普勒超声心动图仪检查的１１４６例临床诊断为正常主动脉瓣成人的左室流出道血流结果，共检出有主动脉瓣返流者７１人。各项检查结果经统计学处理后显示了主动脉瓣返流信号的检出率、返流速度、返流量、超声心动图显示的主动脉瓣增厚，回声增强随着年龄的增长，四者呈正相关。认为这种返流信号可能与随着年龄的增长，心血管病发病率增高，主动脉瓣出现退行性变化有关，提出在老年前期就应有效地防治老年病，以来减缓或防止主动脉瓣膜的退行性变。

A Study on the Relation between Aortic Regurgitation and Age with Color DopplerEchocardiography

adults′ b1ood flow of the leftventricular outflow tract were determinedwith colorDoppler echocardiography,whose aortic valves wereclinically considered normal. The results showedthat) The aortic regurgitation was found in 71 of1146; (2) The velocity and volume of aortic regurgi-tation ,the aortic valvular thickeness and the echointensity were positively correlated with the ags. Conclusion:(1)The aortic regurgitation in nor-mal adults was probably associated with aorticvalvular degeneration.(2 )The senile diseasesshould be prevented in presenium to slow down theoccurrence of aortic valvular degeneration.
