Key result
Noninvasive arm-cuff and echo estimation of LV end-systolic elastance correlates highly with invasive measurements.
Why the study?
Does a novel noninvasive method using arm-cuff pressure and echocardiography accurately estimate LV end-systolic elastance compared to invasive measurements?
Observational
Does a novel noninvasive method using arm-cuff pressure and echocardiography accurately estimate LV end-systolic elastance compared to invasive measurements?
A novel noninvasive method using arm-cuff pressure and echocardiography can accurately estimate LV end-systolic elastance, offering a potential tool for assessing cardiovascular health without invasive procedures.
May enable noninvasive left ventricular elastance assessment; leaves open larger validation before clinical adoption.
In this study, we present a novel model-based method to estimate the left ventricular (LV) end-systolic elastance ( E es ) according to measurement of the patient’s arm-cuff pressure and a routine echocardiography examination. The proposed method was validated in vivo against invasive multiple-loop measurements of E es , achieving high correlation and low bias. This tool could be most valuable for clinicians to assess the cardiovascular health of critically ill patients.
