Brief summary: To investigate the role of racial and socioeconomic disparities in coronary heart disease (CHD) mortality in the United States.

Detailed description: BACKGROUND:

Despite strong decreases in coronary heart disease (CHD) mortality over past decades, there is evidence that racial and socioeconomic disparities in CHD mortality are increasing. CHD surveillance efforts that examine trends within these population subgroups are an important first step in quantifying and reducing disparities. The Atherosclerosis Risk in Communities (ARIC) Study has monitored rates and trends in validated hospitalized myocardial infarction and fatal CHD among black and white adults aged 35 to 74 years in four U.S. communities since 1989.

DESIGN NARRATIVE:

The study will expand the scope of ARIC surveillance by examining variations in the rates and temporal trends in CHD by socioeconomic status (SES), measured at the level of census tract. For CHD events already included in ARIC surveillance (1992-2002), addresses will be obtained from medical records and death certificates and geocoded so that they can be matched with identifiers for census based geographical areas. The ARIC study will contribute yearly updates of abstracted CHD events and addresses for subsequent years (2003-2005). Each event will be linked with census tract level SES indicators available from the 1990 and 2000 censuses. This novel effort will permit an examination of disparities by SES in rates and trends in fatal CHD, hospitalized myocardial infarction, case fatality, use of invasive cardiac procedures and prescription of efficacious medication at time of hospital discharge. In addition, the extent to which racial disparities in CHD and associated treatments are explained by SES will also be explored.

Eligibility criteria: hospitalized and fatal coronary heart disease cases eligibility: within 4 defined geographic areas and ages 35 to 74 years of age
