Chronic Kidney Disease Tied to Heart Problems in
THURSDAY, April 21 (HealthDay News) -- Chronic kidney disease is
common among Americans over 80 years of age and is often linked
with heart disease, a new study says.
Researchers examined the prevalence of chronic kidney disease in
1,028 octogenarians in four U.S. communities enrolled in the
long-term Cardiovascular Health Study All Stars. The prevalence of
chronic kidney disease varied from 33 to 51 percent, depending on
whether the researchers used blood serum levels of creatinine or
cystatin C as markers of the disease.
The findings highlight the fact that using different formulas to
assess kidney function in people in their 80s results in different
estimates of the chronic kidney disease prevalence in this age
group, the investigators said.
The study authors noted that no "gold standard" to estimate the
prevalence of chronic kidney disease in octogenarians has been
developed or validated.
However, no matter which formula was used to assess kidney
function, chronic kidney disease in octogenarians was associated
with cardiovascular disease. Participants with chronic kidney
disease were 1.5 to two times more likely than those without
chronic kidney disease to have coronary heart disease, heart
failure or stroke, according to the report.
The study is published in the April 21 online issue of the
Clinical Journal of the American Society of Nephrology.
The American Academy of Family Physicians has more about
chronic kidney disease.
