目的探讨彩色多普勒超声心动图在老年退行性心脏瓣膜病变临床诊断中的应用价值,并总结其特点,为准确诊断提供依据。方法 120例心内科老年患者,根据年龄分为A组(60~69岁,64例)、B组(70~79岁,46例)、C组(≥80岁,10例)。均采用彩色多普勒超声诊断仪对其进行诊断,对其心脏的病变情况进行观察比较。结果 1 120例患者中检出17例老年退行性心脏瓣膜病变,检出率为14.17%,其中A组、B组和C组检出率分别为9.38%、17.39%和30.00%。检出率随年龄的增长而增加,三组检出率比较差异均具有统计学意义(P<0.05)。2本次共有9例检出主动脉瓣病变,检出率为52.94%(9/17),其中A组3例,B组3例,C组3例,检出率分别为50.00%、37.50%和100.00%。3本组17例退行性心脏瓣膜病变患者中,反流程度存在较大差异,主动脉瓣呈不完全闭合状,为线性反流,占据部分左室流出道。其中3级反流严重,呈喷泉状,并完全占据左室流出道。结论在老年退行性心脏瓣膜病变中的诊断中,应用彩色多普勒超声可直接反映其瓣膜厚度、回声强弱和活动度,还能有效反映其瓣环钙化和反流情况,诊断价值较高,适合进行临床推广。
Objective To explore the value of color Doppler echocardiography in the clinical diagnosis of senile degenerative valvular heart disease, and summarize its characteristics, to provide a basis for accurate diagnosis. Methods A total of 120 elderly patients with cardiology were divided into group A (60-69 years old, 64 cases), group B (70-79 years old, 46 cases) and group C (≥80 years old, 10 cases) according to their age. Color Doppler ultrasound diagnostic apparatus were used to diagnose their lesions of the heart were observed and compared. Results A total of 17 cases of senile degenerative valvular heart disease were detected in 120 cases. The detection rate was 14.17%. The detection rates of group A, group B and group C were 9.38%, 17.39% and 30.00% respectively. The detection rate increased with age, the detection rate of the three groups were statistically significant differences (P <0.05). The detection rate of aortic valve disease was 52.94% (9/17) in 9 cases, including 3 cases in group A, 3 cases in group B and 3 cases in group C, the detection rates were 50.00% and 37.50 % And 100.00%. In this group of 17 cases of patients with degenerative valvular heart disease, there is a large difference in the degree of reflux, aortic valve is not completely closed, as a linear regurgitation, occupy part of the left ventricular outflow tract. Which 3 serious reflux, was fountain like, and completely occupy the left ventricular outflow tract. Conclusion In the diagnosis of senile degenerative valvular heart disease, the application of color Doppler ultrasound can directly reflect the valve thickness, echo strength and activity, but also effectively reflect the ring of calcification and reflux of the situation, the diagnosis of high value , Suitable for clinical promotion.
