  1. Data are expressed as mean ± standard deviation
  2. SHR spontaneously hypertensive rats; SHR-APO SHR treated with apocynin; SHR-DM diabetic SHR; SHR-DM-APO diabetic SHR treated with apocynin; DT peak of developed tension; RT resting tension; +dT/dt maximum rate of tension development; TPT time to peak tension; −dT/dt maximum rate of tension decline; CSA papillary muscle cross sectional area
  3. Two-factor ANOVA; * p < 0.05 vs SHR; # p < 0.05 vs SHR-APO
