Left Atrium Strain and Left Ventricular Diastolic Function in Patients Hospitalized for STEMI

Left ventricular (LV) diastolic dysfunction is
a well-established marker for risk stratification of
patients with acute myocardial infraction (MI).
However, most of the diastolic parameters that were
previously assessed were affected by acute hemodynamic
changes. The left atrium (LA) strain has been proposed
as an alternative approach for LV filling pressure
assessment. The main objective of this study is to
demonstrate the contribution of LA strain in the
assessment of diastolic function 52 patients hospitalized
for STEMI, and the result showed there are a significant
correlation between LA strain alteration and various
parameters: functional class (Killip), LA volume, LV
filling pressures.
