Key result
Acoustic cardiography strongly correlates with LVEDP, LVEF, and maximum contractility in patients with LVSD.
Why the study?
The utility of acoustic cardiographic data in assessing hemodynamic abnormalities associated with left ventricular systolic dysfunction was evaluated using invasive catheterization data.
Do acoustic cardiographic parameters correlate with invasive hemodynamic measurements in patients with left ventricular systolic dysfunction?
Observational (n=17)
Do acoustic cardiographic parameters correlate with invasive hemodynamic measurements in patients with left ventricular systolic dysfunction?
Acoustic cardiographic parameters strongly correlate with invasive hemodynamic measurements in patients with left ventricular systolic dysfunction, suggesting potential utility for non-invasive evaluation and optimization of cardiac resynchronization therapy.
No takes yet. Share an insight, caveat, or question.
Acoustic cardiography may aid noninvasive LVSD assessment; leaves open validation against catheterization before clinical use.
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 showed strong associations with left ventricular end-diastolic pressure, ejection fraction, and maximum contractility in patients with LVSD.
