ARIC是一项在美国四个社区进行的前瞻性流行病学研究：马里兰州华盛顿县、北卡罗来纳州福赛斯县、密西西比州杰克逊和明尼苏达州明尼阿波利斯。该研究旨在监测社区冠心病（CHD）和心力衰竭的发病率和死亡率趋势，并调查亚临床和临床心血管疾病（如CHD、心力衰竭和卒中）的病因、自然史和进展。因此，ARIC包括社区监测部分和队列研究部分。 在社区监测方面，对四个社区进行了调查，以确定约80万名35-84岁男女的住院心肌梗死和冠心病死亡的发生率。从2006年开始，纳入了2005年开始对住院患者（年龄55岁及以上）和门诊患者（年龄65岁及以上）心力衰竭事件的监测。根据新合同，社区监测将继续监测住院MI、CHD死亡和心力衰竭（住院和门诊）的长期趋势。 在队列研究中，通过概率抽样从受监测的四个社区中的每一个社区招募了大约4 000名45-64岁的人。在1987-1989年间，共有15，792名参与者（11，478名白人，4，266名非洲裔美国人和48名其他人）接受了广泛的基线检查。1990- 1992年、1993- 1995年和1996- 1998年进行了三次复查。这些检查收集了有关人口统计学、心理社会和行为因素、饮食摄入量、身体测量以及生物和遗传标记的信息。根据新合同，幸存的队列成员将接受另一次临床检查，以表征心力衰竭阶段，确定导致心室功能障碍和血管僵硬的遗传和环境因素，并评估肺功能的纵向变化并确定其下降的决定因素。每年还通过电话与参与者联系两次，以评估其健康状况。 根据新合同，该研究还将通过心血管结局研究来加强，以评估心力衰竭风险因素和心力衰竭的医疗护理质量和结局。

ARIC is a prospective epidemiologic study conducted in four U.S. communities: Washington County, MD; Forsyth County, NC; Jackson, MS; and Minneapolis, MN. The study is designed to monitor the trends in incidence and mortality of coronary heart disease (CHD) and heart failure in communities, and to investigate the etiology, natural history, and progression of subclinical and clinical cardiovascular disease such as CHD, heart failure, and stroke. Accordingly, ARIC includes a Community Surveillance Component and Cohort Study Component. For the community surveillance, the four communities are investigated to determine the occurrence of hospitalized myocardial infarction and CHD deaths in approximately 800,000 men and women aged 35-84 years. Starting in 2006, surveillance of inpatient (ages 55 years and older) and outpatient heart failure (ages 65 years and older) is included for the events beginning in 2005. Under the new contract, community surveillance will continue to monitor long-term trends in hospitalized MI, CHD deaths, and heart failure (inpatient and outpatient). For the cohort study, approximately 4,000 individuals aged 45-64 years were recruited by probability sampling from each of the four communities under surveillance. A total of 15,792 participants (11,478 whites, 4,266 African Americans, and 48 other) received an extensive baseline examination in 1987-1989. Three repeat examinations were conducted in 1990-92, 1993-95, and 1996-98. The examinations collected information on demographics, psycho-social and behavioral factors, dietary intakes, physical measurements, and biological and genetic markers. Under the new contract, the surviving cohort members will receive another clinic exam to characterize heart failure stages, identify genetic and environmental factors leading to ventricular dysfunction and vascular stiffness, and assess longitudinal changes in pulmonary function and identify determinants of its decline. Participants are also contacted twice a year by telephone to assess health status. Under the new contract, the study will also be enhanced with cardiovascular outcomes research to assess quality and outcomes of medical care for heart failure risk factors and heart failure.
