Local myofiber mechanics (rows) in 4 subepicardial (a) and subendocardial (b) points (columns). From the top to bottom row, Cauchy stress in fiber direction and logarithmic strain as a function of time and stress–strain loops for a healthy heart, CMI5, CMI5wt and CMI5cf. The dotted lines mark the diastolic, isovolumic contraction, systolic and isovolumic relaxation phase, respectively. End-diastole and end-systole are marked with a and respectively
