Key result
Acoustic cardiography reliably detected S3, present in 30.4% of patients with LVEF <50% versus 9.8% with LVEF >50%, and correlated with echocardiographic evidence of impaired LV function.
Why the study?
Does acoustic cardiography correlate with Doppler echocardiography for the detection of left ventricular systolic dysfunction in patients with suspected or known cardiac disease?

Acoustic cardiography provides an affordable and accessible means to assess LV dysfunction in the outpatient setting by reliably detecting S3 and EMAT/LVST ratio, which correlate with reduced ejection fraction on echocardiography.
Züber et al. (2006) conducted a cross-sectional in Suspected or known cardiac disease (n=161). Acoustic cardiography vs. Echocardiography was evaluated on Presence of S3 in patients with LVEF <50% versus >50% (p=<0.05). Acoustic cardiography reliably detected S3, present in 30.4% of patients with LVEF <50% versus 9.8% with LVEF >50%, and correlated with echocardiographic evidence of impaired LV function.
