Determination of preload-recruitable stroke work and elastance by the relationship of arterial blood flow velocity to left ventricular area

Development of a new semi‐quantitative non‐invasive method for evaluating ventricular stroke work

“…Ventricular SW is not only related with the volume of ventricular ejection, but also with the function of the ventricular systole and diastole (Broscheit et al. , 2004; Fincke et al.…”

“…However, the calculation of SW is mainly depended on the ventricular SV and ESP (Erb et al. , 2002; Broscheit et al. , 2004).…”

“…The ventricular stroke work (SW) is one of the most valuable parameters to evaluate the ventricular contractility because it is related with the ventricular ejection fraction, preload and afterload (Ryan et al. , 2002; Broscheit et al. , 2004; Martin et al.…”

“…Calculation of the ventricular work mainly depends on the ventricular stroke volume (SV) and end‐systolic pressure (ESP) measure using the invasive hemodynamic monitoring technique with a pulmonary artery catheter (PAC) (Erb et al. , 2002; Broscheit et al. , 2004).…”

“…The blood flow velocity at the aorta could be substituted for pressure in the LV pressure–volume relationship (Kashem et al. , 2003; Broscheit et al. , 2004).…”
