Color Doppler ultrasonic and clinical analysis of elderly degenerative valvular disease / 第二军医大学学报

ABSTRACT

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.
