Late gadolinium enhancement (LGE) can detect and discriminate myocardial scar/fibrosis of ischemic and non-ischemic etiologies. Our objective was to determine the prevalence and prognosis for ischemic and non-ischemic patterns of LGE in a community-based sample of older adults.
ICELAND-MI is a nested cohort of the Age, Gene/Environment Susceptibility-Reykjavik Study of community-dwelling older adults that intentionally over-sampled diabetic subjects. After excluding subjects with pre-existing heart failure, the cohort size was 900. CMR was used to detect myocardial infarction (MI), major patterns of non-ischemic patterns of LGE as defined by Vöhringer (Herz 2007;32:129-37), and minor patterns of non-ischemic LGE including LGE near the aortic root, mitral annulus, or right ventricular insertion points. The composite end-point was adjudicated hospitalization for heart failure and death.
Subjects with major non-ischemic LGE patterns are at increased risk of developing heart failure and death.
