| Outline of Final Research Achievements |
We have demonstrated that vagal stimulation (VS) prevented the cardiac remodeling and death in post-myocardial infarction rats. However, the precise mechanisms of cardiac protection by VS have not been fully elucidated. To develop a novel cardiovascular regeneration therapy, this study examined that effects of VS on cardiovascular regeneration and cardiac remodeling in acute myocardial infarction (AMI)rats. We investigated that VS promotes cardiovascular regerertion through activation of endogenous cardiac stem cells (CSCs) and prevents cardiac remodeling and dysfunction in AMI rats. The preservation of cardiac function by VS in AMI rats may be mediated partly improve myocardial salvage and reduce myocardial infarct size by cardiovascular regeneration through activation of endogenous CSCs, suggesting that VS approach may be a novel cardiovascular regereration therapy for post AMI and chronic heart failure patients.
