longitudinal strain (GLS) is a sensitive measure of LV dysfunction and is better
than EF at predicting CVD events and deaths. Recently 3D/4D/4D X strain speckle
tracking echocardiography (STE) is used to analyse complex LV mechanics. Interestingly,
HFpEF is related to both GLS and increased Aortic stiffness. TDI of ascending Aorta
is an effective technique to assess Aortic stiffness. The aim of the present study
is to establish normal values of TDI of AA by 2DE and 4D X-strain volumetric and
strain parameters of LV of healthy adults. 102 subjects were enrolled, 72 assessed
by 2DE-GROUP-A, and 30 were analysed by 4D X-strain echocardiography-GROUP-B. Important
TDI parameters of Aortic stiffness were 3.90 ±3.79& 5.23 ± 10.55, (p = NS),
in males & females respectively and Aortic strain were 10.55 ± 7.67% and 9.49
± 5.56%, (p = NS), in males & females respectively. Volumetric data of EF were
64 ± 7.0 % & 65 ± 6.0 %, (p = NS), in males & females respectively and CO
were 5.6 ± 1.5 l/min & 4.91±1.53l/min, (p = NS), in males & females respectively.
Moreover, 4D X-strain STE indices of GLS being -17.29 ± 2.71 & -19.00 ± 3.51,
(p = NS), in males & females, respectively GCS being -15.46 ± 7.1 & -14.12
± 6.15, (p =NS), in males & females respectively and GRS being -24.53 ± 9.8
& -21.93 ± -8.81, (p= NS), in males & females respectively. No previous
data is available, making the research a singular experience.
