Comparison of the prognostic values of three calculation methods for echocardiographic relative wall thickness in acute decompensated heart failure.

ABSTRACT:

Purpose

Left ventricular (LV) wall thickness can be measured at the posterior wall (PW) and the intraventricular septum (IVS) in a parasternal long axis view by transthoracic echocardiography. Thus, there are three methods to calculate relative wall thickness as follows: RWT_PW = 2 × PWth/LVDd; RWT_IVS + PW = (IVSth + PWth) /LVDd; and RWT_IVS = 2 × IVSth/LVDd (IVSth = interventricular septum thickness; LVDd = LV internal dimension at end--diastole; PWth = posterior wall thickness). The aim was to compare the prognostic values of these RWTs in patients with acute decompensated heart failure (ADHF).

Method

This was a single-center, retrospective, observational study at a Japanese community hospital. A total of 389 hospitalized ADHF patients were d
