Study Summary

Heart disease is the leading cause of death in the United States, accounting for one in every four deaths in 2010 and costing over $300 billion annually in health care, medication, and lost productivity. Heart failure with a reduced ejection fraction (HFrEF), a clinical syndrome that develops as a consequence of heart disease, now affects almost 6 million Americans. Within the VA Health Care System, HFrEF hospital admission rates continue to rise, and remain the number one reason for discharge from VA hospitals nationwide. Unfortunately, over one-third of all Veterans suffering from HFrEF die within two years of discharge despite optimized drug therapy, an unacceptably high number. This proposal is focused on how impaired muscle blood flow contributes to exercise intolerance in HFrEF, and on subsequently developing strategies for restoring exercise tolerance and slowing disease progression in this patient group. It is anticipated that knowledge gained from these studies will contribute to improved standard of care, quality of life, and prognosis in this VA patient group.
