Abstract

AIM: Fractal analysis provides a global assessment of vascular network architecture. We examined the relationship of retinal vascular fractal dimension (D(f)) with coronary heart disease (CHD) mortality. METHODS AND RESULTS: We examined the relationship of D(f) with 14-year CHD mortality in a prospective, population-based cohort of 3303 participants aged 49 years or older. D(f) was measured from digitized fundus photographs using computer-automated methods; CHD mortality was documented from Australian National Death Index records. Mean D(f) in this population was 1.441 (standard deviation, 0.024). Over 14 years, there were 468 (14.2%) CHD deaths. Participants with suboptimal D(f) (lowest and..
