目的探讨彩色多普勒超声心动图(Color Doppler echocardiography,CDEC)在诊断老年退行性心脏瓣膜病(Senile degenerative heart valvular disease,SDHVD)应用价值。方法对506例50岁以上受检者进行CDEC。结果筛选出SDHVD 211例,且检出率随年龄增长呈上升趋势,受累瓣膜以主动脉瓣多见,其发生率明显高于二尖瓣。结论老年退行性心脏瓣膜病的主动脉瓣损害明显高于二尖瓣损害,其发生与年龄增长有关;CDEC是诊断老年退行性心脏瓣膜病敏感、实用的方法。
Objective To investigate the value of Color Doppler echocardiography (CDEC) in the diagnosis of senile degenerative heart valvular disease (SDHVD). Methods 506 cases of patients over the age of 50 CDEC. Results A total of 211 cases of SDHVD were selected and the detection rate increased with age. The affected valve was more common in the aortic valve and its incidence was significantly higher than that of the mitral valve. Conclusions The aortic valve lesion in elderly patients with degenerative heart valvular disease is significantly higher than that of mitral valve lesion. The occurrence of CDEC is related to the increase of age. CDEC is a sensitive and practical method for diagnosis of senile degenerative heart valve disease.
