  1. Data are expressed as mean ± standard deviation or median and 25th and 75th percentiles
  2. SHR spontaneously hypertensive rats; SHR-APO SHR treated with apocynin; SHR-DM diabetic SHR; SHR-DM-APO diabetic SHR treated with apocynin; MFS midwall fractional shortening; TDI S’ tissue Doppler imaging (TDI) of mitral annulus systolic velocity; E/A ratio between early (E)-to-late (A) diastolic mitral inflow; IVRT isovolumic relaxation time; E’ TDI of early mitral annulus diastolic velocity
  3. Two-factor ANOVA; * p < 0.05 vs SHR; # p < 0.05 vs SHR-APO
