  1. †: Significant difference compared with normal dogs by multiple comparison (P < 0.05).
  2. SR = peak systolic radial strain; SrRS = Peak radial strain rate during systole; SrRE = Peak radial strain rate during early diastole; SC = Peak systolic circumferential strain; SrCS = Peak circumferential strain rate during systole; SrCE = Peak circumferential strain rate during early diastole.
