Table 3 Left ventricular ejection fraction, pw DTI and speckle tracking strain data

From: Echocardiographic follow-up of patients with systemic sclerosis by 2D speckle tracking echocardiography of the left ventricle

  Baseline (n = 19) Follow-up (n = 19) p- value
LVEF, (%) 63.3 ± 4.2 63.2 ± 5.0 ns
Peak systolic velocity (cm/s) 7.7 ± 1.5 7.8 ± 1.7 ns
Longitudinal PSS
Global longitudinal PSS, (%) -22.0 ± 2.3 -20.8 ± 2.1 0.04
APLAX, (%) -21.5 ± 3.5 -20.3 ± 2.7 ns
4CH, (%) -22.1 ± 2.5 -19.8 ± 3.5 0.006
2CH, (%) -22.2 ± 2.7 -21.7 ± 2.6 ns
  1. Data are expressed as mean ± SD. Pw DTI, pulsed wave doppler tissue imaging; PSS, peak systolic strain; APLAX, apical long axis view; 4CH, apical four chamber view; 2CH, apical two-chamber view; LVEF, left ventricular ejection fraction.
