Left ventricular mass index (LVMI) is a parameter used in echocardiography and cardiac MRI.
LVMI is calculated using the following equations:
- LVMI = LVM (left ventricular mass)/body surface area
- left ventricular mass = 0.8{1.04[([LVEDD + IVSd +PWd]3 - LVEDD3)]} + 0.6
where
- LVEDD = LV end-diastolic dimension (mm)
- IVSd = interventricular septal thickness at end-diastole (mm)
- PWd = posterior wall thickness at end-diastole (mm)

- elevated left ventricular mass has been reported to be associated with hard coronary heart disease events, other forms of cardiovascular related death, and heart failure independent of traditional risk factors and coronary artery calcium scores 4.
