Table 1 Formulas which were used for calculating echocardiographic indices

From: Cardiac insulin-like growth factor-1 and cyclins gene expression in canine models of ischemic or overpacing cardiomyopathy

Echocardiographic indices Formulas
LVEDV (LVDd3 × 7)/(2.4 + LVDd
LVESV (LVDs3 × 7)/(2.4 + LVDs)
LVEF ((EDV-ESV)/EDV) × 100
FS {(LVDd -- LVDs)/LVDd} × 100
IVSFT {(IVSs -- IVSd)/IVSd} × 100
LVFWFT {(LVFWs -- LVFWd)/LVFWd} × 100
RWT 2 × (IVSd/LVDd)
LV mass 1.04 × {(LVDd + IVSd + LVFWd)3 - LVDd3}
  1. LVEDV, left ventricular end diastolic volume; LVESV, left ventricular end systolic volume; LVEF, left ventricular ejection fraction; FS, fractional shortening; IVSFT, interventricular septum fractional thickening; LVFWFT, left ventricular free wall fractional thickening; RWT, relative wall thickness; LVmass, left ventricular mass
