Multiaxial Modulus. Composite multiaxial modulus of left ventricular tissue from mice after sham or myocardial infarction (MI) surgery on postnatal day 1 (P1) or postnatal day 7 (P7), derived from lenticular hydrostatic deformation testing. (a) After P1 surgery, sham (n = 22) and MI hearts (n = 22) exhibited similar myocardial tissue compliance. (b) After P7 surgery, MI hearts (n = 20) exhibited significantly stiffer tissue than sham hearts (n = 20). Data presented as mean ± standard error and compared using two-sample t-test. *Indicates p < 0.05.
