Conclusions
Left ventricular dysfunction measured by TDI is a powerful and independent predictor of death in the general population. When the information on systolic and diastolic performance provided by TDI is combined, the prognostic value of TDI is further strengthened.
.
Combined index (eas index) of diastolic and systolic performance: e’/(a’xs’)

.
Estudo mostra que idosos normais(75a) podem ter até 58ml (Homem) e 47ml (mulher)de volume total do átrio esquerdo.
.
Muito importante para o clínico, o volume do átrio esquerdo têm de ser normatizado para a idade para manter seu valor prognóstico.
