摘　　要：作者对487例60岁以上老年住院患者的超声心动图检查资料进行回顾性分析,结果显示:老年人主动脉瓣钙化(AVC)的发生率为35.1%,并随增龄而增高。3.5%并发主动脉瓣狭窄;47.1%合并瓣膜反流,多为轻微和轻度,AVC 组中瓣膜功能失调的比率明显高于非 AVC 组。心脏听诊对诊断瓣膜功能失调的价值有限,敏感性较低,宜用多普勒超声心动图进一步检查。In 487 patients over 60 years of age,routine 2-dimensional echocardiography demons- trated AVC in 171(35.1%)patients,and 39 patients also had mitral annular calcification (MAC).Doppler echocardiography and color flow image of the 171 AVC patients revealed aortic stenosis(AS)in 6(3.5%),aortic regurgitation(AR)in 80(47.1%)and mitral regur- gitation(MR)in 69(40.6%)patients.To exclude the influence of coexisted systemic hyper- tension and coronary artery disease on valve function,a subgroup of 120 patients without the two coexisted diseases was evaluated.Their incidence of AR was significantly higher in the AVC group than in control group(P<0.001).However,there was no significant difference in the incidence of MR between the two groups.The sensitivity and specificity of ausculta- tion for AS were 66.7% and 94.1%,for AR were 6.6% and 100%,and for MR were 41.7% and 88.0% respectively.The diagnostic rate of auscultation is limited.Two-dimensional and color Doppler echocardiography play an important role in evaluation of AVC.
