Calculate LV Mass using Echocardiogram results

Description

Use commonly reported echocardiographic measurements to calculate Left Ventricular Mass (LVM).

Usage

calculate_lvmass(lvedd, ivsd, lvpwd, bsa, length_units = "cm")

Arguments

lvedd	LV Internal Diameter Diastole
ivsd	LV Septal Thickness Diastole
lvpwd	LV Posterior Thickness Diastole
bsa	Body surface area (m^2)
length_units	units of length used for length (default cm)

Details

Uses methods according to American Society of Echocardiography. Calculations using formulas, with units converted to mm for calculation:

• LV Mass (LVM) = 0.8 \cdot (1.04 \cdot ((LVEDD + IVSD + LVPWD)^3 - LVEDD^3)) + 0.6

• LV Mass Index (LVMI) = LVM/BSA

• Relative Wall Thickness (RWT) = 2 \cdot LVPWD/LVEDD

Value

dataframe of echocardiagraphic LV mass results (LVM, LVMI, RWT)

Examples

calculate_lvmass(lvedd = 50.5, ivsd = 10.7, lvpwd = 13.3, bsa=2.42, length_units = "mm")
