THURSDAY, Sept. 15 (HealthDay News) -- Men and women who develop
visible deposits of cholesterol in the skin around their eyelids
appear to face a higher risk of heart disease in general and
suffering a heart attack in particular, new Danish research
suggests.
The link between the skin condition and heart disease, however,
is characterized as an association, rather than a clear case of
"cause and effect."
Nonetheless, the study team led by Dr. Anne Tybjaerg-Hansen,
from the department of clinical biochemistry at Copenhagen
University Hospital in Denmark, said that the finding could perhaps
help physicians screen for heart disease.
And the research, published in the Sept. 15 online edition of
the
BMJ, "could be of particular value in societies where access to laboratory facilities and thus lipid profile measurement is difficult," the authors said in a journal news release.
Individuals who have the raised yellow patches around the eyes
that indicate the collection of cholesterol in the skin -- known as
"xanthelasmata" -- are not always easily identified in blood tests
as having high cholesterol, the study authors noted.
That said, xanthelasmata and another condition called "arcus
corneae" (distinguished by white or grey rings surrounding the
cornea) have previously been determined to signal deposits of
cholesterol.
To see how such deposits might affect heart disease risk,
between 1976 and 2009 the research team surveyed and tracked nearly
13,000 Danish patients aged 20 to 93 who were participating in the
Copenhagen City Heart Study.
Although none had heart disease at the time of the study launch,
when the investigation began a little more than 4 percent had
xanthelasmata, while nearly a quarter had arcus corneae.
Ultimately, more than 1,870 of the participants had a heart
attack, and nearly 3,800 developed heart disease. Roughly 1,500 had
a stroke and 1,815 developed cerebrovascular disease. All told,
just over 8,500 died by the study's conclusion.
By that point, the study team found that having xanthelasmata
was independently associated with bearing a higher risk for
experiencing a heart attack and developing heart disease. It was
also linked to a greater likelihood of dying within a 10-year
period.
The finding held regardless of gender, smoking history, obesity
and blood pressure/cholesterol levels, with men between the ages of
70 and 79 facing the highest risk.
Arcus corneae, however, was not linked to heart disease or heart
attack risk, the researchers reported.
