Before consideration for transplant or LVAD insertion, patients with congestive heart failure (CHF) are optimized in medical treatment and, if the left ventricular dysfunction is secondary to ischemia, revascularization, consisting of bypass surgery and/or percutaneous intervention, may be performed if feasible. The rationale for considering revascularization in the setting of CHF is based on the concept of hibernating myocardium, i.e. viable myocardium that is hypo-contractile due to hypoperfusion. Our laboratory has been pursuing the concept of microvascular repair as a means of improving symptoms and function in patients with ischemic disease. These efforts have included the application of angiogenic factors and cell based strategies in an attempt to leverage naturally occurring mechanisms for tissue repair. The present proposal is an extension of prior work in our lab and a continuation of our long-standing goal to define mechanisms of ischemic tissue repair and develop novel therapeutics based on these discoveries. If successful the experiments outlined in this proposal could identify novel therapeutics to improve blood flow and function in patients with congestive heart failure.
