Key result
Acoustic cardiography parameters strongly correlate with invasive LVEDP, LVEF, and maximum contractility.
Why the study?
The utility of acoustic cardiographic data in assessing hemodynamic abnormalities associated with left ventricular systolic dysfunction was evaluated using invasive measurements.
Does acoustic cardiography accurately assess hemodynamic abnormalities in patients with left ventricular systolic dysfunction?
Observational (n=17)
Does acoustic cardiography accurately assess hemodynamic abnormalities in patients with left ventricular systolic dysfunction?
Acoustic cardiographic parameters strongly correlate with invasive hemodynamic measurements in patients with LVSD, suggesting potential utility for non-invasive evaluation and optimization of cardiac resynchronization therapy.
No takes yet. Share an insight, caveat, or question.
May aid noninvasive LVSD assessment; leaves open clinical adoption pending larger prospective validation.
Roos et al. (2006) conducted an observational in Left ventricular systolic dysfunction (n=17). Acoustic cardiography vs. Invasive hemodynamic measurements was evaluated on Association with left ventricular end-diastolic pressure, ejection fraction, and maximum contractility. Acoustic cardiographic parameters demonstrated strong associations with invasive hemodynamic measurements of left ventricular end-diastolic pressure, ejection fraction, and maximum contractility.
