International Stroke Conference Closes After More
Than 1,300 Presentations: Links to Some of Best are Below
Five research reports today focus on care for stroke
victims - links to these and more are below
Feb. 8, 2013 The information-packed International
Stroke Conference 2013 on the latest research in stroke care and
prevention ended today with five presentations on new discoveries in
better treatment for stroke victims. Below are links many of the top
presentations are below.
This conference sponsored by the American Stroke
Association is the worlds largest meeting dedicated to the science and
treatment of cerebrovascular disease. This 2½-day conference featured
more than 1,300 presentations that emphasize basic, clinical and
translational sciences as they evolve toward a more complete
understanding of stroke pathophysiology with the overall goal of
developing more effective prevention and treatment.
Study Highlights: Survivors of small-artery strokes who lowered their
systolic blood pressure below 130 mm Hg were less likely to suffer a
hemorrhagic stroke (bleeding in the brain) than those who lowered it to
between 130 mm Hg and 149 mm Hg. There was no significant difference in
the likelihood of clot-caused stroke with lower blood pressure. The
lower blood pressure target was safe, though it did lead to more
episodes of fainting.
Study Highlights: In the first comparison of mechanical clot retrieval
to standard medical care, mechanical devices showed no benefit over
medications. Imaging techniques to measure the amount of salvageable
brain tissue didnt help predict which patients might benefit from
mechanical clot removal. For stroke patients, getting proven emergency
treatment quickly is most important.
Study Highlights: In patients who had endovascular therapy added to
intravenous clot-busting drugs to restore blood flow after a stroke
within seven hours, every 30-minute delay in breaking up the blood clot
causing a stroke was associated with a 10 percent decrease in the
chances of a good outcome. Time proved to be a critical factor in
minimizing brain damage from a stroke regardless of other important
factors, including stroke severity and pre-stroke disability.
Study Highlights: Adding a second drug to aspirin therapy lowered the
risk of a second stroke in the weeks after a clot caused minor stroke or
TIA in Chinese patients. Patients who received clopidogrel in addition
to aspirin were less likely than those on aspirin alone to have a stroke
within three months of their first episode. Both drugs prevent
platelets, a type of blood cell, from sticking together and forming
clots, but no more bleeding occurred among those on dual therapy than in
those on aspirin alone.
Study Highlights: Surgery to improve blood flow to the brain does not
reverse cognitive problems associated with low blood flow in patients
who have experienced a stroke or mini-stroke. Although cognitive
problems were worse in those with poorer blood flow, patients who
received medical treatment plus cranial bypass surgery did no better
than those who received medical treatment for diabetes, high cholesterol
and high blood pressure alone. New approaches are needed to treat this
potentially reversible condition.
