Multi-Ethnic Study of Atherosclerosis
Asymptomatic subjects who were healthy (not showing symptoms of cardiovascular disease) during recruitment / imaging.
MESA (Multi-Ethnic Study of Atherosclerosis) is a large-scale cardiovascular population study (>6,500 participants) conducted in six centres in the USA. It aims to investigate the manifestation of subclinical to clinical cardiovascular disease before signs and symptoms develop. Since MESA participants were determined as healthy during recruitment, patients of this data are identified as asymptomatic subjects. The overall demographics of the MESA study were men and women aged 45-84 years from heterogeneous US population of White, African-American, Hispanic and Chinese ethnicity.
|Number of cases||2,450|
|Gender||1,167 Male / 1,251 Female|
|Age||44 - 84|
|CINE protocol||Gradient Echo (GRE)|
|Scanner||1.5T (mixed vendor)|
All imaging examinations used a four-element phased-array surface coil placed anterior and posterior, ECG gating, and brachial artery blood pressure monitoring. For a subset of the MESA participants (~2,200 cases) 3 tagged short-axis slices were also obtained. Parallel stripe tags were prescribed in 2 orthogonal orientations (0° and 90°) using the same imaging pulse sequence with additional spatial modulation of magnetization encoding gradients.
|Number of cases||1,861 (75.96%)|
|Frames||End-Diastole and End-Systole|
|Type||Endocardium and epicardium|
