PT‐BsAb inhalation improves cardiac function and promotes cardiac repair post MI. a) Schematic illustrating the overall design of animal experiments to test the therapy efficiency of PT‐BsAbs 21 days after treatments in MI mice. b) LVEDV, c) LVESV, d) LVEF, and e) LVFS measured by echocardiography at baseline (4 h post MI) and 21 days afterward in control PBS, control inhalant NT‐BsAbs, i.v. injection of PT‐BsAbs, and PT‐BsAbs with inhalation administration groups. f) Masson's trichrome images showing scar (blue) and viable (red) tissues in the heart at 21 days post treatments. Morphometric parameters including the percentage of g) viable cardiac tissues and h) infarct size measured from Masson's trichrome images via NIH Image J software. N = 6.
