LOINC short name : LV Myo/Ht exp 2.7 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 an index based on height 2.7. 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. [PMID: 2936235];
