Relationships between peak EL during each phase and other
parameters (univariate analysis)
Table 4 shows the correlation coefficients of peak EL to other
variables. Figure 2 shows a scatter plot of peak EL during each phase
and some variables.
Age, systolic BP, and mean BP did not correlate with peak EL during any
phase. Diastolic BP correlated with ED-EL (r=-0.251, p=0.011). The LV
mass index (LVMI) and LAVI did not correlate with peak EL during any
phase.
ED-EL correlated with the indices of diastolic function (E wave peak
velocity, A wave peak velocity, E/A, E/e’ in the septal side, and E/e’
in the lateral side; p<0.05). LD-EL also correlated with A
wave peak velocity (r=0.513, p<0.001) and the E/A ratio
(r=-0.358, p<0.001). ED-EL and LD-EL both correlated with the
parameters of LVOT (diameter, peak velocity, and the time velocity
integral (TVI); p<0.05).
Sys-EL correlated with EF (r=0.342, p=0.001) and the parameters of LVOT
(diameter, peak velocity, and TVI; p<0.05). It also correlated
with the A wave peak velocity (r=0.233, p=0.017) and the E/A ratio
(r=-0.240, p=0.014).
