Scientists from Uppsala University Hospital and Uppsala University in Sweden have developed a method that predicts the risk of stroke using a blood test that reflects the state of the brain. Research results It was published In Circulation magazine.
In the study, scientists analyzed levels of neurofilament proteins in blood samples from more than 3,000 volunteers with atrial fibrillation. Neurofilaments form the “scaffolding” of neurons and are released into the bloodstream (where they can be found) in response to injury and lack of oxygen.
For a year and a half, scientists observed the participants and monitored their health. It turned out that people with a high level of neurofilaments in their blood had a three times higher risk of stroke than those with a low concentration of these proteins.
According to scientists, the assessment of neurofilament levels, along with the search for biomarkers of heart failure, could significantly improve the prediction of stroke. This test could be especially useful for people with atrial fibrillation, a heart rhythm disorder that is a strong and independent risk factor for stroke.
The next phase of the study will be to examine the effects of different treatments on neurofilament levels and assess their contribution to reducing the risk of stroke and death.
