Table 4 Left and right ventricular strain

From: Quantifying longitudinal right ventricular dysfunction in patients with old myocardial infarction by using speckle-tracking strain echocardiography

  The control group (n = 45) The OMI group (n = 74)
LV PSS (L: 4-chamber) (%) −17.6 ± 3.1 −12.0 ± 5.1*
LV PSS (L: 2-chamber) (%) −18.8 ± 3.8 −12.2 ± 5.5*
LV PSS (L: long axis) (%) −17.3 ± 3.5 −11.3 ± 4.7*
LV PSS (R) (%) 52.1 ± 15.0 31.6 ± 22.8*
LV PSS (C) (%) −20.4 ± 3.6 −12.3 ± 5.5*
  1. OMI old myocardial infarction, LV left ventricular; PSS peak systolic strain, L longitudinal, R radial, C circumferential. *P <.05 vs. the Control group.
