美国国家心脏，肺和血液研究所，简称NHLBI，于1948年成立。含有1个办公室，5个研究部门和1个研究中心，分别是：司长办公室（OD），为研究所的计划提供总体规划，指导，协调和评估；翻译研究与实施科学中心（CTRIS），计划、促进和支持研究，以确定最佳策略，确保在临床和公共卫生环境中成功整合循证干预措施；血液病和资源司（DBDR），是研究非肿瘤性血液病的原因，预防和治疗的领导者；心血管科学部（DCVS），支持研究，以促进对整个生命周期促进心脏和血管健康的理解和干预措施；校外研究活动部（DERA），为NHLBI主任提供领导和建议，以制定，实施和协调校外研究合同，赠款和培训计划政策；校内研究部（DIR），使命是进行强有力的科学和临床研究，从而更好地了解生物学和临床病理学；肺部疾病科（DLD），支持对肺部疾病和睡眠障碍的原因，诊断，预防和治疗的研究。

NHLBI以心脏、肺和血液为研究重心，投入大量精力和资金来深入研究有关疾病发生的基本原因，并致力于将基本发现转化为临床实践，以促进新兴科学家和医生的培训和指导，并向公众传达研究进展，让大家对相关疾病的预防和治疗的相关知识有更多了解，以减少人类疾病发生的概率。时至今日，NHLBI在心脏、肺和血液的研究上均有取得成就。

The National Heart, Lung and Blood Institute, or NHLBI for short, was founded in 1948. Contains 1 office, 5 research departments and 1 research center, namely: Office of the Director (OD), which provides master planning, guidance, coordination and evaluation of the Institute's plans; Translation Research and Implementation Science Center (CTRIS), which plans, facilitates and supports research to identify the best strategies to ensure the successful integration of evidence-based interventions in clinical and public health settings; The Department of Hematology and Resources (DBDR), a leader in the study of the causes, prevention and treatment of non-neoplastic hematological diseases; Department of Cardiovascular Sciences (DCVS), which supports research to advance understanding and interventions for promoting heart and blood vessel health throughout the life cycle; The Department of External Research Activities (DERA), which provides leadership and advice to NHLBI Directors to develop, implement, and coordinate policies for off-campus research contracts, grants, and training programs; In-Campus Research Department (DIR), whose mission is to conduct strong scientific and clinical research leading to a better understanding of biology and clinical pathology; The Department of Pulmonary Diseases (DLD), which supports research into the causes, diagnosis, prevention, and treatment of lung diseases and sleep disorders.

With the heart, lungs and blood as its research focus, NHLBI invests a lot of energy and money in the in-depth study of the underlying causes of the occurrence of diseases, and is committed to translating basic findings into clinical practice to promote the training and guidance of emerging scientists and physicians, and to communicate research progress to the public, so that everyone can have a better understanding of the prevention and treatment of related diseases to reduce the probability of human disease occurrence. Today, NHLBI has made achievements in heart, lung and blood research.
