Brief summary
This will test the safety and efficacy of a new drug called recombinant human Neuregulin-1 in patients with chronic stable heart failure. We hope to establish that recombinant human Neuregulin-1 (rhNRG-1) can be administered safely and that its administration results in improved heart structure and function as measured by cardiac MRI at 12 days and 3 months.
