Abstract

The major advances in our understanding and management of heart failure (HF) in recent decades have not fully benefited all segments of our population. HF still represents a growing epidemic, especially for African-Americans, in whom the burden of HF is even greater. The recently reported beneficial effects of the fixed combination of isosorbide dinitrate and hydralazine (ISDN+HYD) in the African-American Heart Failure Trial (A-HeFT), has led to both the FDA approval of this agent and its endorsement by the latest HF guidelines. The properties of ISDN+HYD are well known as its components are mature agents, readily available in generic formulations that have been used for decades in other indications. However, fixed-dose ISDN+HYD represents the first drug to undergo targeted clinical development and to be approved for use in a specific ethnic group. As such, A-HeFT and the approval of ISDN+HYD represent landmark events that merit further scrutiny.
