Well then, What the hell is the solution? You don't describe a problem without at least suggesting a solution. A great stroke association president would be reaming these researchers out about that.

Anemia, a lack of red blood cells, may be linked to a higher risk of
death in older adults who have had a stroke, according to new research
in Journal of the American Heart Association, the Open Access Journal of
the American Heart Association/American Stroke Association.
Anemia is common in patients with acute stroke. Both anemia and low
hemoglobin levels, which are proteins in red blood cells that carry
oxygen throughout the body, are also common in older people, said Phyo
Myint, M.D., senior study author and Professor of Medicine of Old Age at
the University of Aberdeen in Scotland.
Researchers examined data from 8,013 hospital patients, average age
77, admitted with acute stroke between 2003 and 2015. Researchers
assessed the impact of anemia and hemoglobin levels on death at
different time points up to one year following stroke.
Researchers found that anemia was present in about a quarter of
patients with stroke upon admission and was associated with a higher
risk of death for up to one year following eitherischemic stroke
(clotted blood vessel) or hemorrhagic stroke (ruptured blood vessel).
Additionally, elevated hemoglobin levels were associated with poorer
outcomes and a higher risk of death, mainly within the first month
following stroke, meaning both low and high levels of hemoglobin could
be associated with a higher risk of death after stroke.
“We found that the likelihood of dying from ischemic stroke is about
two times higher in people with anemia compared to those without it, and
the risk of death from hemorrhagic stroke is about 1.5 times higher,”
Myint said. “So there’s the potential for a much poorer outcome if
somebody comes in with stroke and they’re also anemic.”
In addition to the U.K. Regional Stroke Registry, researchers
systematically reviewed relevant literature published to date. They used
20 previous studies to conduct one larger study by compiling data from a
wide range of countries, increasing the study population to 29,943
stroke patients. This better quantified the impact of anemia and
increased the generalizability of the study findings, researchers said.
Researchers believe the study emphasizes the impact of anemia on
stroke outcomes and the need for increased awareness and interventions
for stroke patients with anemia.
“One example of an intervention might be treating the underlying
causes of anemia, such as iron deficiency, which is common in this age
group,” said Raphae Barlas, co-author and medical student at the
University of Aberdeen, who carried out the project as a summer research
program scholarship recipient. “As the study has convincingly
demonstrated, anemia does worsen the outcome of stroke, so it is very
important that we identify at-risk patients and optimize the
management.”
