Cardiovascular Sciences


The NHLBI Division of Cardiovascular Sciences (DCVS) plans and directs research grant, contract, and training programs to support basic, clinical, population, and health services research on the causes, prevention, and treatment of cardiovascular diseases. These programs encompass institute and investigator-initiated basic research, targeted research, specialized centers and clinical trials. The DCVS maintains surveillance over developments in its program areas and assesses the national need for research on the causes, prevention, diagnosis, and treatment of cardiovascular disease. The DCVS ensures that effective new techniques, treatments and strategies resulting from medical research are transferred to the community through professional, patient, and public education programs in a timely manner. DCVS-supported research also includes a broad array of epidemiological studies to describe disease and risk factor patterns in populations and to identify risk factors for disease; clinical trials of interventions to prevent and treat disease; studies of genetic, behavioral, sociocultural, and environmental influences on disease risk and outcomes; and studies of the application of prevention and treatment strategies to determine how to improve clinical care and public health.

The Division is comprised of three programs, in which reside eight branches, and the Office of Research Training and Career Development, and the Office of Biostatistics Research. These are described below.

Adult and Pediatric Cardiac Research Program

Atherothrombosis and Coronary Artery Disease Branch. Supports basic, translational, and clinical research on the etiology, pathogenesis, prevention, diagnosis, and treatment of coronary artery disease and atherothrombosis.

Heart Development and Structural Diseases Branch. Supports basic, applied, and clinical research in normal and abnormal cardiovascular development as well as the etiology, pathogenesis, prevention, diagnosis, treatment of pediatric and adult structural heart disease, and heart transplantation.

Heart Failure and Arrhythmias Branch. Supports basic, translational, and clinical research on normal cardiac function and pathogenesis to improve the diagnosis, treatment, and prevention of heart failure and arrhythmias.

Basic and Early Translational Research Program

Advanced Technologies and Surgery Branch. Supports basic, translational, and clinical research on innovative and developing technologies for the diagnosis, prevention, and treatment of cardiovascular diseases.

Vascular Biology & Hypertension Branch. Supports basic, translational, and clinical research on vascular biology and the etiology, pathogenesis, prevention, diagnosis, and treatment of hypertension and vascular diseases.

Population Sciences Program

Clinical Applications and Prevention Branch. Supports, designs, and conducts research on behavioral, environmental, clinical, and healthcare approaches to reduce occurrence and consequences of cardiovascular diseases.

Epidemiology Branch. Supports, designs, and conducts research in the epidemiology of cardiovascular, lung, blood and sleep diseases and disorders.

Women?s Health Initiative Branch. Supports clinical trials and observational studies to improve understanding the causes and prevention of major diseases affecting the health of women. Current studies focus on cardiovascular disease, cancer, and fractures, in collaboration with NCI, NIAMS, NIA, NINDS, and ORWH.

Office of Research Training and Career Development. This office supports research training and career development programs for individuals at many educational levels, from high school to faculty, as well as training programs for individuals from under-represented groups. Many of these programs are designed to take emerging and promising scientific and technological advances from discovery through pre-clinical and clinical studies. A K12 institutional training program, Research Career Development in Vascular Medicine, was established in 2007 to provide comprehensive clinical research training for physicians wanting to specialize in vascular medicine. The office also collaborates with the scientific community and professional organizations to ensure that training programs meet both the current and future needs of the cardiovascular research workforce.

Office of Biostatistics Research (OBR). Provides statistical expertise to members of all Divisions of the NHLBI and performs diverse functions in planning, designing, implementing and analyzing NHLBI-sponsored studies. The OBR is concerned with designing efficient studies and monitoring data while studies are ongoing. The OBR?s methodological interest concern survival analysis, longitudinal data analysis, and efficient study designs, including the monitoring of ongoing clinical studies for efficacy and safety. Recently the OBR has made contributions to statistical genetics and has extended its expertise to bioinformatics.
