ABSTRACT
BACKGROUND:
Hemodynamic and functional evaluation with Doppler and
tissue Doppler study as a part of comprehensive
echocardiography is essential but normal
reference values have never been reported from Korean normal
population especially according to age and
sex.
METHODS:
Using Normal echOcaRdiographic Measurements in a KoreAn
popuLation study subjects, we obtained normal
reference values for Doppler and
tissue Doppler echocardiography including tricuspid annular velocities according to current guidelines and compared values according to
gender and
age groups.
RESULTS:
Mitral early diastolic (E) and late diastolic (A) velocity as well as E/A ratio were significantly higher in
women compared to those in
men. Conversely, mitral peak systolic and late diastolic annular velocity in both septal and lateral mitral annulus were significantly lower in
women compared to those in
men. However, there were no significant differences in both septal and lateral mitral early diastolic annular (e') velocity between
men and
women. In both
men and
women, mitral E velocity and its
deceleration time as well as both E/A and E/e' ratio considerably increased with age. There were no significant differences in tricuspid inflow velocities and tricuspid lateral annular velocities between
men and
women except e' velocity, which was significantly higher in
women compared to that in
men. However, changes in both tricuspid inflow and lateral annular velocities according to age were
similar to those in mitral velocities.
CONCLUSION:
Since there were significant differences in Doppler and
tissue Doppler echocardiographic variables between
men and
women and changes according to age were even more considerable in both
gender groups, normal Doppler echocardiographic values should be differentially applied based on age and
sex.
