Left ventricular mass index

Left ventricular mass index (LVMI) is a parameter used in echocardiography 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


  • LVEDD = LV end-diastolic dimension (mm)
  • IVSd = interventricular septal thickness at end-diastole (mm)
  • PWd = posterior wall thickness at end-diastole (mm)
