Vienna—For years, physicians have noticed
that patients with congestive heart failure who have anemia fare less well
than those with a normal hematocrit, but the link was largely dismissed as
a mere association. In recent years, however, researchers have begun to question
whether anemia is only a marker for the problem or whether it may cause or
exacerbate heart failure—and if treating anemia will improve outcomes.
