Questions about kidney disease? Risk factors? Signs and symptoms? Are you concerned about yourself, a friend or family member? Ask Dr. Spry.
The 26 million American adults with chronic kidney disease
are at significantly higher risk of experiencing a heart attack or stroke,
according to new results presented in this month’s American Journal of Kidney Diseases, the publication of the
National Kidney Foundation, and released today at the foundation’s 2008 Spring
Clinical Meetings, held here.
“The study found that people with kidney disease were 34%
more likely to have experienced heart attack or stroke,” says Peter A.
McCullough, MD, MPH, lead author and Vice Chair of the National Kidney Foundation’s
Kidney Early Evaluation Program. “People who are diagnosed with kidney disease
need to take extra precautions to protect themselves from these other,
life-threatening consequences of their disease.”
In addition, “these findings reaffirm the importance of
identifying kidney disease at its early stages, when treatment is most
effective, to prevent further long-term complications,” McCullough adds.
The results add to the already long list of findings gleaned
from the NKF’s Kidney Early Evaluation Program (KEEP), which screens people
with the most common risk factors for kidney disease – diabetes, high blood
pressure, or a family history of chronic kidney disease (CKD).
Over the course of CKD, the kidneys become less able to
perform vital functions that help maintain overall health, including filtering
wastes and excess fluids from the blood.
Previous research has suggested that CKD and cardiovascular disease might be linked – showing, for instance, that kidney function influences the development of an irregular heart rhythm.
During the study, researchers reviewed data collected from
nearly 70,000 people who participated in KEEP, and another 17,000 participants
in the National Health and Nutrition Examination Survey (NHANES), which conducts
nationally representative cross-sectional surveys of the
The authors found that more than one-quarter of KEEP
participants had CKD, along with 15% of those screened by the NHANES. More than
15% of people with CKD who participated in either survey said they had
experienced either heart attack or stroke. Only 8% of KEEP participants and 4%
of NHANES participants who did not have CKD reported a history of either stroke
or heart attack.
People who participated in KEEP were more likely to die
during a short follow-up period.
“These findings confirm the risks associated with CKD – a
higher likelihood of heart attack, stroke, and death,” says McCullough.
The National Kidney Foundation is dedicated to preventing
kidney and urinary tract diseases, improving the health and well-being of
individuals and families affected by these diseases and increasing the
availability of all organs for transplantation.
