The Multi-Ethnic Study of Atherosclerosis (MESA) is a study of the correlates, predictors, and progression of subclinical cardiovascular disease (CVD) in a diverse population-based sample of men and women aged 45-84 who had no evidence of clinical CVD at baseline. During the initial funding period of MESA, 6,814 participants were recruited from six field centers during 2000-2002 and examined for evidence of subclinical coronary atherosclerosis, using computed tomography, cardiac MRI, carotid ultrasound, flow-mediated brachial artery dilation, radial artery tonometry, ankle-brachial index measurement, and retinal photography. A number of other variables including abdominal aortic CT, carotid MRI, cardiac MRI tagging for measures of regional myocardial function; established and putative laboratory risk markers; socioeconomic, psychological, behavioral and environmental characteristics; and genetic variants were assessed in subsets of the MESA cohort. Examinations of selected components were repeated over five subsequent examinations spanning approximately 16 years and the cohort has been continuously followed for clinical CVD events since the baseline examination. This proposal is written in response to the NHLBI RFP (No. 75N92020D00003, Multi-Ethnic Study of Atherosclerosis (MESA) Exam 7- Task Area B) that seeks to enable a limited reexamination by the MESA field centers of MESA participants. Task Area B will involve protocol development and finalization, exam preparation activities, a limited re-examination of all surviving and willing MESA participants from the field center, and close-out activities for Exam 7. The recruitment goal for Exam 7 is approximately 3,000 participants across all field centers. The performance of Exam 7 will allow continued scientific collaborations. which will contribute to the following MESA IV scientific objectives: 1) enhance statistical power to perform analyses of predictors of clinical outcomes, particularly in informative subgroups; 2) study the progression of subclinical to clinical CVD; and 3) identify new risk factors or interactions among factors that inform disease pathophysiology. The study will continue to support in-depth ancillary studies that are funded outside of the NHLBI contract. These studies will be operationally integrated into the main study, and the data will be shared across the entire “MESA Suite” of studies, per current MESA and NIH data-sharing policies. The study’s data will be provided to interested investigators through a defined process that encourages maximum data utilization while protecting participant confidentiality.
