Abstract
Aortic stiffness is associated with
cognitive decline and cerebrovascular disease late in life, although
these associations
have not been examined in young adults.
Understanding the effects of aortic stiffness on the brain at a young
age is important
both from a pathophysiological and public health
perspective. The aim of this study was to examine the cross-sectional
associations
of aortic stiffness with cognitive function and
brain aging in the Framingham Heart Study Third Generation cohort (47%
men;
mean age, 46 years). Participants completed the
assessment of aortic stiffness (carotid–femoral pulse wave velocity), a
neuropsychological
test battery assessing multiple domains of
cognitive performance and magnetic resonance imaging to examine
subclinical markers
of brain injury. In adjusted regression models,
higher aortic stiffness was associated with poorer processing speed and
executive
function (Trail Making B–A; β±SE, −0.08±0.03; P<0.01), larger lateral ventricular volumes (β±SE, 0.09±0.03; P<0.01) and a greater burden of white-matter hyperintensities (β±SE, 0.09±0.03; P<0.001).
When stratifying by age, aortic stiffness was associated with lateral
ventricular volume in young adults (30–45 years),
whereas aortic stiffness was associated with
white-matter injury and cognition in midlife (45–65 years). In
conclusion, aortic
stiffness was associated with cognitive function
and markers of subclinical brain injury in young to middle-aged adults.
Prospective
studies are needed to examine whether aortic
stiffening in young adulthood is associated with vascular cognitive
impairment
later in life.
