Heart and Vascular Diseases
Research Making a Difference
Research Making a Difference
For more than 60 years, the NHLBI has led the fight against heart and vascular diseases. The NHLBI supports research to advance the understanding of and interventions for pediatric and adult heart and vascular diseases, including heart attack, heart failure, stroke, and congenital heart disease. Over this period, steady, long-term investments in biomedical research have contributed to a 71 percent decrease in death rates due to coronary heart disease, yet more remains to be done. Heart disease is still the leading cause of death for men and women. The NHLBI has a long history of groundbreaking research in treatments for high blood pressure, a common condition that increases the risk for heart disease and stroke, two of the leading causes of death for Americans.
- NHLBI research helped understand the causes, prevention, and treatment of heart disease and reduced death rates from coronary heart disease by 71 percent.
- The SPRINT study found that intensive high blood pressure treatment in people 50 years or older reduces heart events and the risk of death from such events.
- The RAID Trial found that a drug to treat angina reduced the risk of rapid heart rhythms that may otherwise require an implantable cardioverter defibrillator.
- The CLEVER Trial led the Centers for Medicare and Medicaid Services to reimburse supervised exercise therapy for a form of peripheral artery disease.
- For more than a decade, the NHLBI’s Pediatric Heart Network has improved the care of children with heart diseases.
- The Pediatric Cardiac Genomics Consortium identified a link between gene mutations that lead to congenital heart disease and neurodevelopmental abnormalities.
The NHLBI will continue to build on its successes as it aims to better understand how to prevent, diagnose, and treat heart and vascular diseases. In 2016, NHLBI released its Strategic Vision, which will guide the Institute’s research activities for the coming decade. Many of the objectives, compelling questions, and critical challenges identified in the plan focus on heart and vascular biology and diseases. Training the next generation of heart and vascular scientists is also a high priority for the NHLBI. Learn more about how we are strategically moving research forward to improve health.
Scientific advances have created opportunities to create a future in which we have an improved understanding of the complex interplay of environmental, behavioral, and molecular factors that promote heart and vascular health; detect heart and vascular diseases in their earliest stages before they cause symptoms; to prevent disease progression; repair defective or damaged hearts with stem cell and tissue engineering techniques; and generate new therapeutics for chronic conditions, such as heart failure and high blood pressure.
The NHLBI will continue to pursue opportunities to improve our understanding of how heart and vascular diseases impact women and diverse populations. For example, researchers have learned that women are more likely than men to have coronary microvascular disease, which affects the tiny arteries in the heart. Our research also seeks to address health disparities related to heart and vascular diseases, including high blood pressure and heart disease.

- Heart-Healthy Aging: The NHLBI supports research on healthy aging to help more people live longer lives free from heart and vascular diseases.
- Immunology, Virology, and AIDS: The NHLBI supports research to help understand the role of the immune system in heart and vascular disease and how having HIV/AIDS influences heart and vascular disease prevention and care.
- Obesity, Nutrition, and Physical Activity: The NHLBI supports research on how lifestyle choices related to eating patterns and physical activity contribute to heart and vascular disease.
- Sleep Science and Sleep Disorders: The NHLBI supports research on the interplay of sleep disorders such as sleep apnea, and heart and vascular diseases, such as high blood pressure and heart disease.
Advancing the Research
The NHLBI is advancing heart and vascular diseases research in many ways. Learn about some of the NHLBI’s efforts to support research on heart and vascular diseases.
We Perform Research
The NHLBI Division of Intramural Research (DIR) and its Cardiovascular Branch conducts research on diseases that affect the heart and blood vessels. Specific projects aim to answer clinically relevant questions in diagnostics, therapeutics, and interventions. Other DIR groups, such as the Systems Biology Center, perform research on heart and vascular diseases.
We Fund Research
NHLBI’s Division of Cardiovascular Sciences supports research to advance our understanding of and interventions for pediatric and adult cardiovascular diseases. It also supports the development of innovative technologies to diagnose, prevent, and treat heart and vascular diseases. The Center for Translation Research and Implementation Science supports research to translate these discoveries into clinical practice.
The Promise of Precision Medicine
Through NHLBI’s Trans-Omics for Precision Medicine (TOPMed) program, researchers will use data from studies focused on heart, lung, blood and sleep disorders to better predict, prevent, diagnose, and treat diseases based on a patient’s unique genes, environment, and molecular signatures. Learn more about NHLBI precision medicine activities.
Studying Innovations to Improve Heart and Vascular Disease Outcomes
The Cardiothoracic Surgical Trials Network (CTSN) is an international clinical research enterprise that studies heart valve disease, arrhythmias, heart failure, coronary heart disease, and the complications of surgery. The trials spans from early translation to the completion of six randomized clinical trials, three large observational studies, and many other studies with more than 14,000 participants.
Supporting Heart Failure Research Collaboration
The Heart Failure Clinical Research Network (HFN) conducts clinical trials to evaluate treatments for acute and chronic heart failure. The HFN brings together nine Regional Coordinating Centers and additional clinical sites in the United States to form a collaborative platform to research strategies that address the increasing public health burden of heart failure.
Supporting Child Health Research Collaboration
The Pediatric Heart Network (PHN) involves hospitals in the United States and Canada that conduct studies to improve outcomes and quality of life in children with congenital or acquired heart diseases. The PHN and its companion consortia, the Cardiovascular Development Consortium and the Pediatric Cardiac Genomics Consortium, make up the Bench to Bassinet program and cover basic to complex clinical research.
Promoting a Clinical Trial Network to Address Emergency Medicine
The Resuscitation Outcomes Consortium (ROC) is a clinical trial network that tested treatments to address high morbidity and mortality rates from out-of-hospital cardiac arrest and severe traumatic injury. The trans-NIH Network for Emergency Care Clinical Trials: Strategies to Innovate EmeRgENcy Care Clinical Trials Network (SIREN)will conduct trials to improve outcomes in emergency departments and pre-hospital settings.
Addressing Barriers to Early Diagnosis and Treatment
The Vascular Interventions/Innovations and Therapeutic Advances (VITA) Program is a translational program that supports and accelerates early stage development of promising diagnostics and treatments. VITA seeks to address unmet clinical needs for vascular diseases, particularly in underserved medical communities.
Informing Improvements to Clinical Care and Public Health
The Systolic Blood Pressure Intervention Trial (SPRINT) showed the benefit of lower blood pressure targets to reduce heart and vascular diseases and death. The SPRINT Memory and Cognition in Decreased Hypertension (SPRINT-MIND) Trial studies the effect of this treatment on cognitive function in adults 50 years or older. SPRINT results influenced clinical guidelines, which will improve care for millions of people.
Determining the Most Effective Therapies to Manage Stable Ischemic Heart Disease
The International Study of Comparative Health Effectiveness with Medical and Invasive Approaches (ISCHEMIA) is a 5,000-participant, 350-site international trial comparing invasive and conservative strategies to prevent heart and vascular events in patients with stable ischemic heart disease. ISCHEMIA and ISCHEMIA-Chronic Kidney Disease Trial (ISCHEMIA-CKD) results will inform future clinical care.
Advancing Research in HIV/AIDS-related Heart and Vascular Disease
The NHLBI AIDS Program promotes research in HIV-related heart, lung, and blood diseases. The NHLBI will lead the joint Multicenter Aids Cohort Study (MACS) and the Women’s Interagency HIV Study (WIHS). The Randomized Trial to Prevent Vascular Events in HIV (REPRIEVE) tests the efficacy of statins to reduce the risk of heart and vascular disease in HIV-infected adults.
Understanding How Heart and Vascular Diseases Impact Diverse Populations
NHLBI population and epidemiology studies in different populations have made major contributions to understanding the causes and prevention of heart and vascular diseases. Studies include: Atherosclerosis Risk in Communities Study (ARIC); Coronary Artery Risk Development in Young Adults Study (CARDIA); Framingham Heart Study (FHS); Hispanic Community Health Study/Study of Latinos (HCHS/SOL); Jackson Heart Study (JHS); Multi-Ethnic Study of Atherosclerosis (MESA); Strong Heart Study (SHS); and the Women’s Health Initiative (WHI).
Providing Information About Treating Risk Factors for Heart Disease
The Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial (ALLHAT) was a large study that enrolled people with high blood pressure and high blood cholesterol, two major risk factors for heart disease. The trial had two parts: a blood pressure study and a cholesterol study. ALLHAT’s findings have informed how we treat high blood pressure and high blood cholesterol.
Providing Access to NHLBI Biologic Specimen and Data Repositories
The Biologic Specimen and Data Repositories Information Coordinating Center (BioLINCC) centralizes and integrates biospecimens and clinical data that were once stored separately in NHLBI’s Biologic Specimen Repository (Biorepository) or Data Repository. Researchers can find and access available resources with BioLINCC’s secure website, which maximizes the value of these resources and advances heart, lung, blood, and sleep research.
