Echocardiographic reference ranges for normal cardiac Doppler data in
healthy Turkish population : ECHO-DOP-TR Trial
Abstract
Aim Doppler echocardiography has become the standard imaging modality
for diastolic function and provide pathophysiological insight into
systolic and diastolic heart failure. In this study we aimed to obtain
normal echocardiographic Doppler parameters of healthy Turkish
population. Methods Among 31 collaborating institutions from all regions
of Turkey, 1154 healthy volunteers were enrolled in this study.
Predefined protocols were used for all participants during
echocardiographic examination and The American Society of
Echocardiography and European Association of Cardiovascular Imaging
recommendations were used for echocardiographic Doppler measurements.
Results A total of 967 healthy participants were enrolled in this study
after applying exclusion criteria. Echocardiographic examination was
obtained from all subjects following predefined protocols. Mitral E wave
velocity and E/A ratio were higher in females and decreased
progressively in advancing ages. E wave deceleration time and A wave
velocity were increased with aging. Assessment of tissue Doppler
velocities showed that left ventricular lateral e’, septal e’ and septal
s’ were higher in younger subjects and in females. E/e’ ratio was
increased progressively with advancing decades. Right ventricular e’and
s’ were decreased but a’ was increased with increasing age. Septal e’
lower than 8 cm/s was 1.9% in the fifth decade and 13.7% in ages older
than 50-years. The E/e’ ratio greater than 15 (and also 13) was not
found. Conclusion This study, for the first time, provides
echocardiographic reference ranges for normal cardiac Doppler data in
healthy Turkish population which will be useful in routine clinical
practice as well as in future clinical trials.
