A new study has revealed that people who exhibit a resistance to aspirin may be more likely to have more severe strokes than people who respond to the drug. The study also found that larger areas of the brain were affected by the stroke in people with aspirin resistance.
Aspirin works to help keep blood platelets from clotting. Blot clots can cause strokes and people at risk of stroke often take aspirin to reduce their risk of having another stroke. However, a percentage of patients may be insensitive, or resistant, to aspirin, which in turn may negate the aspirin's effect of lowering stroke risk.
Study author Mi Sun Oh, MD, of Hallym University College of Medicine in South Korea, said, "Eventually we may be able to identify people who are likely to be resistant to aspirin and give them higher doses or different drugs to prevent blood clots. However, we need better ways to identify people with aspirin resistance before any changes can be made. For now, people who are taking low-dose aspirin to prevent blood clotting and stroke should continue to do so."
The study will be presented at the American Academy of Neurology's 67th Annual Meeting in Washington, DC, April 18 to 25, 2015.
