assessed by RT3DE, in healthy volunteers and consecutive patients with various<br />

car<strong>di</strong>ovascular <strong>di</strong>sorders.<br />

Methods. Two-hundred-thirty-one patients (mean age 57,2±15,2 y., 112 male)<br />

were stu<strong>di</strong>ed. Of these, 68 were healthy volunteers and 163 were consecutive<br />

patients with more than 3 car<strong>di</strong>ovascular risk factors (111), documented coronary<br />

artery <strong>di</strong>sease and normal systolic function (29), ischaemic and non ischaemic<br />

systolic dysfunction (16). Two-<strong>di</strong>mensional Doppler and TDI echocar<strong>di</strong>ographic<br />

parameters and LAVmax, assessed by RT3DE were analyzed. For the statistical<br />

analysis LAVmax was <strong>di</strong>vided into tertiles and correlated with clinical, 2DE and<br />

Doppler fin<strong>di</strong>ngs. Oneway ANOVA statistic analysis was used to compare<br />

variables, t value was corrected by age and body surface area.<br />

Results. See Table.<br />

Conclusion. A progressive left atrial volume increase is <strong>di</strong>rectly correlated with<br />

age, LV mass and <strong>di</strong>astolic dysfunction and inversely correlated with left<br />

ventricular function.<br />
