ABSTRACT
Background:
Four-dimensional echocardiography technique results in marked improvements in terms of quality and accuracy in assessing the size and function of heart chambers, especially the left atrium as its geometric variation has a notable impact on the results when using traditional echocardiographic techniques alone. Thus, this study aimed at investigating the probability of significant functional and morphological changes in the left atrium with advancing age using Four-dimension echocardiography.Method:
Four-dimensional technique derived left atrial phasic volumes and functions were assessed in (30) healthy subjects with mean age of 73.6 (±3.6) years and (30) young subjects with mean age of 23.17 (±3.5) years.Results:
Old age group showed a significant increase in maximum left atrial volume index, minimum left atrial volume index and pre-atrial contraction left atrial volume index compared to young age group (31.52±1.09 vs. 26.44±1.03, P < 0.001), (17.93±0.43 vs. 15.89±0.44, P < 0.00) and (25.73±1.003 vs. 22.34±0.77, P < 0.01), respectively. In the old age group, the passive left atrial emptying function (LAEF) significantly decreased (20.43±0.25% vs. 24.96±0.93%, p<0.00), while the active LAEF significantly increased (37.36±1.33% vs. 32.65±1.13%, P< 0.009) in comparison to the values of the young subjects.Conclusions:
These results suggest that left atrial structural as well as functional changes occur with advancing age in absence of evident pathological causes and 4-dimentional echocardiography can be used to evaluate these changesPalavras-chave
