ABSTRACT: The left atrium (LA) has been recognized as a morphophysiological barometer of left ventricular (LV) diastolic dysfunction. Because in the myocardial
ischemia cascade where LV diastolic dysfunction often precedes LV systolic
dysfunction, the LA which fashions as an early marker of diastolic anomaly, could
equally reflect a declining LV function and/or be a good predictor of potential
sequelae. We assessed this association of LA function with reduced LV systolic
function among hospitalized patients. Among patients with reduced LV ejection
fraction, LA passive ejection fraction was lower (0.172 ± 0.12 vs. 0.232 ± 0.14,
p = 0.013) whereas LA kinetic energy was higher (6.48 ± 6.3 vs. 4.57 ± 3.5, p =
0.005). Echocardiographic assessment of LA function, therefore, appears
correlated with LVEF and could be important when risk stratifying hospitalized
patients.
