by cube method;
LOINC short name : LV Myo mass/BSA US.M-mode cube;
LOINC description : The myocardial index is the left ventricular (LV) mass normalized for body size, which
can be approximated by different measures including body surface area (BSA) and height.
This term represents a BSA-based index. BSA can be calculated by a number of methods
including the Mostellar and Du Bois formulas, or in some cases the average adult BSA,
1.73 m2, is used by default. The cube function is a method for calculating left ventricular
mass from M-mode echocardiography measurements and assumes a long- to short-axis length
ratio of 2:1. The formula is as follows: LV mass 1.04(IVSd LVIDd PWTd) 3 - LVID
3), where IVSd interventricular septal thickness, LVIDd left ventricular internal
diameter (short axis), and PWTd posterior wall thickness, all measured during end-diastole.
