In conclusion, reduced nitric oxide bioactivity contributes to cardiac and vascular remodeling. Nitricoxide-enhancing therapy can slow cardiac andvascular remodeling. African-Americans with heart failure exhibit nitric oxide deficiency and a dramatic benefit from nitric-oxide-enhancing therapy. The potential benefit of this therapy in other groups with heart failure and in other vascular remodeling disease processes requires further study.
