Age-related valvular regurgitation: a study by pulsed Doppler echocardiography.
Key result
Valvular regurgitation detected by pulsed Doppler echocardiography increased significantly with advancing age (r=0.81, p<0.001), being present in all subjects over age 80.
Why the study?
What is the prevalence of valvular regurgitation detected by pulsed Doppler echocardiography in healthy aging individuals?
Population
176 apparently healthy volunteers with no history or physical evidence of cardiac abnormality, ages 40 to 90.
Design
Cross-sectional

Valvular regurgitation detected by Doppler echocardiography is extremely common in the elderly and can be considered a normal age-related finding in the absence of other cardiac disease.
Cite This Study
Akasaka et al. (1987) conducted a cross-sectional in Valvular regurgitation (n=176). Pulsed Doppler echocardiography was evaluated on Prevalence of valvular regurgitation (r = 0.81, p=<0.001). Valvular regurgitation detected by pulsed Doppler echocardiography increased significantly with advancing age (r=0.81, p<0.001), being present in all subjects over age 80.
