老年退行性心脏瓣膜病的彩色多普勒超声与临床分析

Color Doppler ultrasonic and clinical analysis of elderly degenerative valvular disease

采用美国 ATL HDI- 5 0 0 0型二维彩色多普勒超声诊断仪 ,对 36 2例 6 0岁以上老年患者进行超声检测。结果检出退行性心脏瓣膜病 176例 (4 8.6 % ) ,其中男性检出率为 5 1.6 % ,女性为 4 1.8%。检出率随年龄增长呈上升趋势 ,相同年龄组男女性别之间无显著差异。受累瓣膜以主动脉瓣多见 ,其发生率明显高于二尖瓣 ,未检出三尖瓣及肺动脉瓣退变。瓣膜退变患者中 ,多数合并存在高血压病、冠心病、糖尿病。表明老年患者心脏退行性瓣膜病主要发生于主动脉瓣 ,其次为二尖瓣 ;其发生与年龄增长有关 ,高血压、冠心病等合并症是导致或加速瓣膜退变的重要因素。

By use of color Doppler ultrasonography (ATLHDI 5000,made in USA),a prospective study was made in 362 aged (greater than or equal to 60 years) patients (252 males and 110 females) for a period of 3 years.There were 176 patients (48.2%,130 males and 46 females) had degenerative vavular disease (DVD).The incidence increased with the aging of the population.There were no evident differences between males and females.Degenerative aortic valvular deformation was most frequently found (in 171 cases),followed by mitral (in 24 cases).The complications were hypertension,diabetes and coronary heart disease.It suggests that the DVD in the elderly mainly occurs in aortic valves,then in mitral value.Its incidence increases with aging.Complications such as hypertension,diabetes and coronary heart disease are important risk factors of DVD.
