Left Ventricular Stroke Work Index (LVSWI) Formula

This page contains the Left Ventricular Stroke Work Index (LVSWI) formula which calculates LV (Left Ventricular) workload and contractility. Patients with higher LV workload capacity are indicated by higher Left Ventricular Stroke Work Index (LVSWI). LVSWI formula in this page requires Left ventricular stroke work index, pulmonary artery wedge pressure, artery systolic pressure, stroke volume, patient weight and patient height as input values to perform calculation.

LVSWI Formula

Formula:

BSA = 0.007184 × W0.425 × H0.725
L = ((S - P) × V × 0.0136) / BSA


Where,

L = Left ventricular stroke work index (LVSWI )
P = Pulmonary artery occlusion pressure
S = Mean Arterial Pressure
V = Stroke volume
W = Patient weight(kg)
H = Patient height(cm)
