| Outline of Final Research Achievements |
Heart decease is one of the major causes of death in Japan. Recently a new therapeutic strategy in which relatively weak polymeric hydrogels are injected into the infarcted area of heart was proposed. It seems to stop the cardiac remodeling and loss of heart function. In the present project, PEG-poly(lactic acid) injectable hydrogels with various properties were injected to the rat myocardial infarction model, and the heart functions were monitored. The biodegradable hydrogel resulted in the recovered heart function as well as the conventional nondegradable hydrogels. However, the inflammation was much milder than the conventional hydrogel. It can be then concluded that the synthetic biodegradable thermoresponsive hydrogel can be a good material for treating myocardial infarction.
