老年患者中主动脉瓣狭窄的临床诊断颇为困难。收缩期杂音、缓慢上升的颈动脉波,以及有关的临床症状对诊断均无特异性。故常借助于左心导管检查以明确诊断。因此,在老年患者主动脉瓣狭窄的诊断上,探讨一项敏感和特异的非侵入性检查方法十分必要。作者使用颈动脉波和心音图对以下几组对象进行检查。一组:44例正常青年人(14—47岁,平均29岁);二组:44例正常老年人(52—83岁,平均 Aging in patients with aortic stenosis clinical diagnosis is quite difficult. Systolic murmur, a slowly rising carotid artery wave, and related clinical symptoms are not specific for diagnosis. Often with the help of left heart catheterization to confirm the diagnosis. Therefore, in the diagnosis of aortic stenosis in elderly patients, to explore a sensitive and specific non-invasive inspection method is necessary. The authors used the carotid artery wave and phonocardiogram to examine the following groups of subjects. One group: 44 normal young people (14-47 years, average 29 years); two groups: 44 normal elderly (52-83 years, mean
