    摘要: A system delivers cardiac pacing therapy and chemical and/or biological therapy to modulate myocardial tissue growth in a heart after myocardial infarction (MI). The system includes an agent delivery device to release one or more agents to an MI region to modulate myocardial tissue growth in that region, and a cardiac rhythm management (CRM) device to deliver pacing pulses to enhance the effects of the one or more agents by altering myocardial wall stress and cardiac workload. In one embodiment, the system is an implantable system including an implantable agent delivery device and an implantable CRM device.

    摘要: Methods, devices, kits and compositions to treat a myocardial infarction. In one embodiment, the method includes the prevention of remodeling of the infarct zone of the ventricle using a combination of therapies. The method may include the introduction of structurally reinforcing agents. In other embodiments, agents may be introduced into a ventricle to increase compliance of the ventricle. The prevention of remodeling may include the prevention of thinning of the ventricular infarct zone. Another embodiment includes the reversing or prevention of ventricular remodeling with electro-stimulatory therapy. The unloading of the stressed myocardium over time effects reversal of undesirable ventricular remodeling. These therapies may be combined with structurally reinforcing therapies. In other embodiments, the structurally reinforcing component may be accompanied by other therapeutic agents. These agents may include but are not limited to pro-fibroblastic and angiogenic agents.

    摘要: A gene regulatory system detects ischemia events and is capable of delivering a biologic therapy in response to the detection of an ischemic event or the reception of a command. The biologic therapy protects the heart from ischemic damage by regulating the expression of an exogenously introduced gene product. In one embodiment, the gene regulatory system includes an implantable system that emits at least one gene regulatory signal in response to the detection of the ischemic event or the reception of the command. The gene regulatory signal directly or indirectly regulates gene expression of the gene product.
