COPD, even when mild, limits heart function (USA)

"A common lung condition, COPD (chronic obstructive pulmonary disease) diminishes the heart's ability to pump effectively even when the disease has no or mild symptoms, according to research published in the Jan. 21 issue of the New England Journal of Medicine. The study is the first time researchers have shown strong links between heart function and mild COPD. The research was funded by the National Heart, Lung, and Blood Institute (NHLBI) of the National Institutes of Health. Researchers have long known that severe cases of COPD have harmful effects on the heart, decreasing its ability to pump blood effectively. The new results suggest that these changes in the heart occur much earlier than previously believed, in mild cases and even before symptoms appear. One in five Americans over the age of 45 has COPD, but as many as half of them may not even be aware of it" - EurekAlert
