Abstract
Introduction: Cardiovascular health may be used for prevention of cerebral vascular disease. We evaluated whether improvement of cardiovascular health within midlife and from midlife to late-life were each associated with lower prevalence of MRI markers of cerebral vascular disease at late-life. Methods: 1,638 participants from the Atherosclerosis Risk in Communities (ARIC) Study took part in two visits at midlife (mean ages 53 at ARIC visit 1 and 59 at visit 3), and a late-life visit (mean age 76). A cardiovascular health Life’s Simple 7 score (range 0-12/0-14, depending on diet availability) including six/seven items was calculated at each visit, with weight assigned to each item as poor (0), intermediate (1), or ideal (2). Participants underwent 3T brain MRI scans in 2011-2013 (late-life visit). Outcomes were white matter hyperintensity volume, microbleeds, and lacunar, subcortical, and cortical infarcts at late-life. Linear and logistic regression models were used to assess the associations of cardiovascular health with MRI markers of cerebral vascular disease. Results: Thirty nine percent of participants had high cardiovascular health at midlife visit 1, 32% at midlife visit 3, and 33% at late-life. Improvement of cardiovascular health within midlife and from midlife to late-life were each associated with a lower prevalence of cerebral vascular disease markers. For example, improvement in cardiovascular health (per point) from midlife to late-life was associated with smaller white matter hyperintensity volume (Beta:-0.07 [95%CI:-0.10,-0.04]), and lower odds of microbleeds (OR:0.93 [0.90,0.97]), lacunar (OR:0.93 [0.89,0.97)], subcortical (OR:0.93 [0.89,0.97])], and cortical infarcts (OR:0.92 [0.87,0.97)] (Figure). Conclusions: Improving cardiovascular health within midlife and from midlife to late-life may prevent development of cerebral vascular disease.
