ABSTRACT
<p><b>OBJECTIVE</b>To test the effects of autologous skeletal myoblast transplantation on the hemodynamics in dogs with coronary microembolization-induced chronic heart failure (CHF).</p><p><b>METHODS</b>CHF models were successfully induced in 19 dogs and divided into ASMT group (n=9) and control group (n=10). The myoblasts were injected into the embolized region in the 9 dogs of the ASMT group, and saline was injected in the control dogs, and the hemodynamics of the dogs were evaluated 5 weeks after the injections.</p><p><b>RESULT</b>Compared with saline injection, ASMT significantly increased dP/dtmax, MAP and LVSP (P<0.05) and decreased LVEDP (P<0.05) 5 weeks after myoblast transplantation. Desmin and Brd-U immunofluorescent staining showed myoblast survival at the injected sites in the dogs.</p><p><b>CONCLUSION</b>ASMT provides mild improvements in the hemodynamics of dogs with CHF.</p>
