Table 2 Echocardiographic results in patients at baseline and at the 4-year follow-up examination, and in controls

From: Overweight and obesity impair left ventricular systolic function as measured by left ventricular ejection fraction and global longitudinal strain

  Patients, n Patients baseline Patients follow-up p-value Patients baseline vs. follow-up Controls, n Controls baseline p-value Patients baseline vs. controls
LA, mm/m2 380 20.4 (3.1) 20.6 (3.1) ns 183 20.8 (4.0) ns
LVEDV, mL/m2 371 46.1 (13.1) 46.5 (12.0) < 0.05 180 48.8 (11.3) < 0.01
LV mass, g/m2 324 101.8 (30.3) 101.7 (26.9) ns 174 94.5 (29.9) < 0.001
LVEF, % 370 52.0 (10.5) 53.0 (11.0) ns 180 57.0 (9.0) < 0.001
MAPSE, mm 370 12.0 (2.0) 12.0 (2.0) ns 184 12.3 (2.3) ns

  1. Data are presented as median and (interquartile range)
  2. LA LVEDV and LV mass are indexed by body surface area, ns not significant, LA left atrium, LVEDV left ventricular end-diastolic volume, LV left ventricle, LVEF left ventricular ejection fraction, MAPSE mitral annular plane systolic excursion, E transmitral E-wave velocity, early diastolic mitral annulus velocity
