Study Suggests Rheumatoid Arthritis Linked to Heart
THURSDAY, Dec. 9 (HealthDay News) -- One year after a person is
diagnosed with rheumatoid arthritis they are at a 60 percent
increased risk of heart attack compared to people without the
disease, a new study suggests.
The study included almost 7,500 patients who were diagnosed with
rheumatoid arthritis, a chronic autoimmune disease marked by
painful inflammation of the lining of the joints, and more than
37,000 people without the disease. The study was conducted between
between 1995 and 2006; median follow-up was just over four years
with a maximum follow-up of 12 years.
According to the Swedish researchers, the risk of heart attack
rose 60 percent one to four years after the rheumatoid arthritis
diagnosis, compared to people without the condition, and remained
at the same level for five to 12 years after diagnosis. The risk of
any type of ischemic (blocked blood flow) heart disease increased
50 percent one to four years after a rheumatoid arthritis diagnosis
compared to those without the condition, and it remained at that
level five to 12 years after diagnosis.
The study appears in the December issue of the
Journal of Internal Medicine.
"Our findings emphasize the importance of monitoring a patient's heart risk from the moment they are diagnosed with rheumatoid arthritis, as the risk rises rapidly in the first few years," lead author Marie Holmqvist, of the Karolinska Institute in Stockholm, said in a journal news release.
She added that it "is also very clear that more research is
needed to determine the mechanisms that link these two health
