Mild COPD May Hurt the Heart

(I got this from a friends page. Unfortunately we both share Copd.)
Thanks for the great article Barb <3


Study Shows Chronic Obstructive Pulmonary Disease Is Linked to Impaired Heart Function

Jan. 20, 2010 -- Even a mild case of chronic obstructive pulmonary disease (COPD) may have a major impact on the heart, according to a new study.

"This study shows that COPD, even in its mildest form, is associated with diminished heart function," Susan B. Shurin, MD, acting director of the
National Heart, Lung, and Blood Institute of the National Institutes of
Health,
which funded the research, says in a news release. "We now have evidence
that
the presence of even mild COPD may have important health implications
beyond
the lungs."

Researchers say heart failure caused by lung disease is well documented in people with severe COPD, but this is the first study to show a link
between
mild forms of lung disease and impaired heart function.

"We found that there appears to be a linear relationship between lung function and heart function, and even a small hit to the lungs
negatively
affects heart function as well," says researcher Graham Barr, MD, DrPH,
assistant professor of medicine and epidemiology at Columbia University
Medical
Center, in the news release.

"These results raise the intriguing possibility that treating lung disease may, in the future, improve heart function," says Barr. "Further
research is
needed to prove whether treating mild COPD will help the heart work
better."

COPD is the fourth leading cause of death in the U.S. and is strongly related to smoking. It includes the conditions of sl(this,'','embd-lnk');"">emphysema and chronic
bronchitis. COPD makes it
progressively more difficult to breathe.

The study, published in the New England Journal of Medicine, used magnetic resonance imaging (MRI) to measure heart function in 2,816
adults aged
45 to 84. Of the participants, 13% were smokers, 38% were former
smokers, and
49% never smoked.

The extent of emphysema in the participants was also determined with breathing tests and images of the chest.

The results showed the link between lung disease and impaired heart function was strongest in current smokers. But researchers also found an
association
between mild emphysema and decreased heart function in people who had
never
smoked.

"We used sensitive measures to pick up small differences in healthy people," says Barr. "We demonstrated that even mild COPD is associated with
subclinical
reductions in heart function, probably since not enough blood is
entering the
heart due to vascular problems in the lungs."
