摘　　要：目的 观察老年性主动脉瓣钙化的演变过程,寻找本病的变化规律。方法 用超声心动图连续随访10年29例老年性主动脉瓣钙化患者,作前后对比,同时将20例同龄正常人作为对照组。结果 病例组随病程延长而进行性加重,经过10年钙化瓣叶由30个增加到48个。跨瓣压差增大,10年前18例的跨瓣压差(PG)小于16mmHg,10年后均增加,多在17-45mmHg,最高达118mmHg。全组反流程度增加。对照组较10年前相比,11个瓣膜有钙化,PG>16mmHg者2例,6例件轻度反流。结果 老年性主动脉瓣钙化一旦发生,其病变速率显著高于生理性退变。Objective To observe the developing procedure of senile aortic valve calcification and look for the developing rule of thd disease. Methods Following up of 29 consecutive patients for 10 years with echocardigraphy. At the same period, we compare with normal controls in the same ages. Results In patient' s group, lesions of diseases were aggravated with prolongation of the course. The numbers of the calcific valve were incre-sased from 30 to 48 after 10 years. The transvalvular pressure gradient also increased, to 17 - 45mmHg after 10 years in 18 patients under 16mmHg pressure gradient group, whereas the even most one was 118mmHg. The numbers and extent of regurgitation were also increased. In control group, there were 11 cases of valve calcification,2 cases whose pressure gradient > 16mmHg and 6 cases with mild regurgiton. Conclusion Once the senile aortic valve calcification has developed, it will be acted apparently progressive more than physiologic deterioration.
