Table 3 Radial and circumferential strain values in control and db/db mice by STE measurements

From: Speckle tracking echocardiography in the diagnosis of early left ventricular systolic dysfunction in type II diabetic mice

Variables Control Db/db Pvalue
8 weeks    
Radial strain(%) 43.43 ± 7.03 42.73 ± 6.77 P > 0.05
Circumferential strain(%) -29.92 ± 2.47 -29.95 ± 4.01 P > 0.05
12 weeks    
Radial strain(%) 45.43 ± 8.36 45.14 ± 9.75 P > 0.05
Circumferential strain(%) -30.20 ± 3.83 -28.75 ± 4.82 P > 0.05
16 weeks    
Radial strain(%) 42.37 ± 4.40 31.19 ± 3.95 P < 0.01
Circumferential strain(%) -30.71 ± 2.24 -22.54 ± 3.57 P < 0.01
  1. The table shows at 8 and 12 weeks of age, there was no significant difference in left ventricular radial strain and circumferential strain between db/db mice and age-matched controls (P > 0.05). At 16 weeks of age, radial strain and circumferential strain in db/db mice were lower than in control mice (P < 0.01).
