There
were no statistically significant differences with regard to age related
RA volumetric measurements (P=0.271). RALS had a trend towards
decreasing with age but did not achieve statistical significance (P=
0.362). RAVI and RALS had a negative correlation with age but did not
reach statistical significance (r = -0.060, P = 0.526; r = -0.153, p
value = 0.129 respectively (Figure 3)
Figure 3. Right atrial volume (ml/m2) and right atrium
longitudinal strain negatively correlated with age of participants age
(r = -0.060, P = 0.526; r = -0.153, p value = 0.129 respectively).
Regarding traditional RV functional parameters (TAPSE, RV E’, A’, and RV
S’) there were no statistically significant differences. RV diastolic
function declined with age with RV E’/A’ showing a decrease with age (P=
0.002). Left ventricular diastolic function parameters showed a decrease
with age but remained within ASE guideline specified normal limits
(P<0.001).
