As shown in [Table 3], the changes in LVEDd,
IVST, LVPWT, LVM, LVMI, LAd, LVESd, EDV, ESV, SV, EF, and FS, at baseline and 12 months after treatment, were similar among the three groups (all P > 0.05).{Table 3}
LVM (g) = 1.04 [[(LVPT + LVLD +
IVST).sup.3]-[(LVLD).sup.3]] - 14g
Participants were positioned in a 45[degrees] left lateral decubitus position and an integrated M-mode and two-dimensional analysis was performed to determine interventricular septal (
IVST) and left ventricular (LV) posterior wall thickness (PWT) at the diastole as well as LV end-diastolic (LVEDD) and end-systolic (LVESD) diameters.
In this regard, it is worth noting the way in which Carew is described in a theatrical dispute that occurred in 1630/1.(58) William Davenant's play, The
Ivst Italian, appears to have been poorly received on its first performance at the Blackfriars Theatre in October 1629.
Left ventricular end-diastolic diameter (LVDD), left ventricular end-systolic diameter (LVSD), interventricular septal thickness (
IVST), and left ventricular posterior wall thickness (LVPWT) were measured using a 2D-targeted M-mode method.
LV mass (g) = 0.8 x [1.04 x {[(LVID + LVPWT +
IVST).sup.3] - [LVID.sup.3]}] + 0.6 (1)
End-diastolic volume, end-systolic volume, stroke volume, ejection fraction, Left Ventricular Internal Dimensions in systole (LVIDs), Left Ventricular Internal Dimensions in diastole (LVIDd), fraction shortening (FS) of internal diameter, Interventricular Septum Thickness (
IVST), Left Ventricular Posterior wall diameter (LVP wed), cardiac output and cardiac index.
The LV mass (LVM) was calculated with the Devereux formula as LVM (g) = 1.04 ([LVID + PWT + IVST][sup]3 −LVID[sup]3) −14 (LVID: LV internal dimension; PWT: Posterior wall thickness;
IVST: IVS thickness) and indexed to the body surface area (dividing LVM by body surface area).[sup][8] Left atrial volumes were determined at ventricular end-systole according to area-length method using apical 4- and 2-chamber views.

Measurements included the diastolic thickness of the interventricular septum (
IVST), left ventricular posterior wall (PWT), and the internal diameter of the left ventricle at the end of diastole (LVDd).
Left ventricular mass (LVM) = 1.04 [[(LVIDd + PWT +
IVST).sup.3] - [LVIDd.sup.3]] - 14 gm.
