NHLBI's Director is Gary H. Gibbons, M.D.
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. Research is related to the causes, prevention, diagnosis, and treatment of heart, blood vessel, lung, and blood diseases, and sleep disorders. The NHLBI plans and directs research in development and evaluation of interventions and devices related to prevention, treatment, and rehabilitation of patients suffering from such diseases and disorders. It also supports research on clinical use of blood and all aspects of the management of blood resources. Research by scientific institutions and individuals is supported by research grants and contractss through the NHLBI Extramural Program, while the NHLBI Division of Intramural Research conducts state-of-the-art research on the NIH Besthesda campus in its own laboratories.
For health professionals and the public, the NHLBI conducts educational activities, including development and dissemination of materials in the above areas, with an emphasis on prevention.
The NHLBI supports research training and career 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.
