This is a randomized, double-blind, placebo controlled Phase II study is designed to assess the safety and efficacy of using JVS-100 to treat heart failure.

90 subjects with ischemic cardiomyopathy will be randomized to receive a single dose of 15 or 30 mg of JVS-100 or matching placebo. Subjects will be randomized 1:1:1 to receive either placebo, 15 mg or 30 mg of JVS-100. Subjects will be monitored overnight for 18-24 hours post dose and have scheduled visits at 3 days post-injection for safety evaluations. All subjects will be scheduled for follow-up visits at approximately 30 days (1 month), 120 days (4 months), and 360 days (12 months) to assess safety and cardiac function.

• Must meet wall thickness criteria

• Subject has an implanted, functional AICD

• Subjects with diabetes must have had an ophthalmologist exam within the last year showing no active proliferative retinopathy

• Subject receiving stable optimal pharmacological therapy defined as:

  • ACE inhibitor and/or ARB, and Beta-blocker for 90 days with stable dose for 30 days unless contraindicated
  • Diuretic in subjects with evidence of fluid retention
  • ASA unless contraindicated

• mild aortic stenosis

• normal aortic valve

• normal aortic pressure gradient

• aortic pressure gradient < 20 mmHg

  • Presence of an artificial aortic valve
  • Subjects with aortic aneurysm >3.8 cm
  • Mitral regurgitation defined as "severe" measured by echocardiography at the clinical site.
  • Patients with planned mitral valve repair or replacement surgery
  • Any patient with a history of cancer will be excluded unless:

• The cancer was limited to curable non-melanoma skin malignancies and/or

• The cancer was removed by a successful tumor resection, with or without radiation or chemotherapy treatment, 5 years or more prior to enrollment in this study without recurrence

Subjects must have the following results on age appropriate cancer screenings:

• Subjects age 50 or older have had a Fecal occult blood test (FOBT) or fecal immunochemical test (FIT) that was negative within the last year

• Women age 40 or older have had a mammogram that was negative within the last year
• Men above age 45 have had a Prostate-Specific Antigen (PSA) blood test and digital rectal examination (DRE) that was negative within the last year
• At the request of the site principal investigator, any subject with a non-negative result thought to be due to a non-cancer-related condition will be evaluated by the medical monitor for enrollment

Exclusion Criteria (ctd):
