Table 3 Comparison of the peak segmental and global longitudinal rotational degrees in the systolic period between HCM patients and normal subjects (mean ± s.d.)

From: Left ventricular systolic function changes in hypertrophic cardiomyopathy patients detected by the strain of different myocardium layers and longitudinal rotation

  Base-Septal(°) Mid-Septal(°) Apex(°) Mid-lateral(°) Base-lateral(°) Global
HCM (36) −9.45 ± 2.65 −7.90 ± 3.08 −5.07 ± 3.61 −2.49 ± 4.85 0.15 ± 6.14 −4.92 ± 2.65
Normal (36) −9.21 ± 3.11 −4.52 ± 4.01 1.28 ± 3.42 6.38 ± 3.63 9.66 ± 3.63 0.02 ± 2.42
P-Value 0.687 < 0.001 < 0.001 < 0.001 < 0.001 < 0.001
  1. Base-Septal the base of the septal wall, Mid-Septal the middle of the septal wall, Apex the apex of the left ventricular, Mid-lateral the middle of the lateral wall, Base-lateral: the base of the lateral wall
