Objective
To
explore
the
correlation
of
evaluation
on
left
ventricle
diastolic
function
by
W2
of
carotid
artery
and
tissue
Doppler
imaging,
and
hope
to
provide
conferences
for
the
evaluation
on
left
ventricle
diastolic
function
in clinic.
Methods
66
cases of healthy volunteers were enrolled and such parameters of them were measured as W2 of
carotid
artery
of
both sides,
peak
early
diastolic
velocity
(E)
and
late
diastolic
velocity
(A)
of
mitral flow and their ratio (E/A), peak early diastolic velocity (E
鈥?/p>
) and late diastolic velocity (A
鈥?/p>
)
of
mitral
annulus
and
their ratio
(E
鈥?/p>
/A
鈥?/p>
),
isovolumic
relaxation
time
(IVRT). The
correlation
among all these parameters were analyzed.
Results There were positive correlation between E
鈥?/p>
/A
鈥?/p>
and E/A
(r
锛?/p>
0.604
锛?/p>
p
锛?/p>
0.01); negative correlation between E/E
鈥?/p>
and E
鈥?/p>
/A
鈥?/p>
(r
锛?/p>
-0.252
锛?/p>
p
锛?/p>
0.05); no correlation between W2 and E
鈥?/p>
/A
鈥?/p>
, E/A, E/E
鈥?/p>
, IVRT (p
锛?/p>
0.05).
Conclusion Left
ventricle diastolic function can be reflected better by E
鈥?/p>
/A
鈥?/p>
, E/A, E/E
鈥?/p>
and IVRT but there still
exists
localization
in
evaluating
left
ventricle
relaxing
function
with
these
parameters.
Further
research deserves in evaluating left ventricle diastolic function by non-invasive carotid W2.
