Representative H&E stained myocardium tissue sections for sham (A) and cryo-infarcted (B) groups from n=6 animals are displayed at 40X magnification. Cardiac muscle occupies more space in sham tissue sections than in infarcted ones (C). The average fiber length (Mean ± SD) is seen to decrease in cryo-infarcted samples (D) as well as an increase in waviness (E). Deviation from the red dashed line in E suggests fibers become wavy.
