2. Program Overview

The National Heart Institute (NHI) was established in 1948 through the National Heart Act with a mission to support research and training in the prevention, diagnosis, and treatment of cardiovascular diseases (CVD). Twenty-four years later, through section 413 of the National Heart, Blood Vessel, Lung, and Blood Act (P.L. 92-423), Congress mandated the Institute to expand and coordinate its activities in an accelerated attack against heart, blood vessel, lung, and blood diseases. The renamed National Heart, Lung, and Blood Institute (NHLBI) expanded its scientific areas of interest and intensified its efforts related to research on diseases within its purview. Over the years, the Institute's areas of interest have grown to encompass genetic, genomic, and proteomic research, systems biology, sleep disorders, and the Women's Health Initiative (WHI).

The mission of the NHLBI is to provide leadership for a national program in diseases of the heart, blood vessels, lung, and blood; sleep disorders; and blood resources management. The Institute:

  • Plans, conducts, fosters, and supports an integrated and coordinated program of basic research, clinical investigations and trials, observational studies, and demonstration and education projects related to the causes, prevention, diagnosis, and treatment of heart, blood vessel, lung, and blood diseases and sleep disorders conducted in its own laboratories and by other scientific institutions and individuals supported by research grants and contracts.
  • Plans and directs research in development and evaluation of interventions and devices related to the prevention of heart, lung, and blood diseases and sleep disorders and the treatment and rehabilitation of patients who suffer from them.
  • Conducts research on the clinical use of blood and all aspects of the management of blood resources.
  • Supports career training and development of new and established researchers in fundamental sciences and clinical disciplines to enable them to conduct basic and clinical research related to heart, blood vessel, lung, and blood diseases; sleep disorders; and blood resources through individual and institutional research training awards and career development awards.
  • Coordinates relevant activities with other research institutes and all Federal health programs in the above areas, including the causes of stroke.
  • Conducts educational activities, including development and dissemination of materials for health professionals and the public in the above areas, with emphasis on prevention.
  • Maintains continuing relationships with institutions and professional associations, and with international, national, state, and local officials, as well as voluntary agencies and organizations working in the above areas.
  • Oversees management of the WHI.

Each year, the NHLBI assesses progress in the scientific areas for which it is responsible and updates its goals and objectives. As new opportunities are identified, the Institute expands and revises its areas of interest. Throughout the process, the approach used by the Institute is an orderly sequence of research activities that includes:

  • Acquisition of knowledge
  • Evaluation of knowledge
  • Application of knowledge
  • Dissemination of knowledge.
