New biomarkers can help preventing stroke
Taking into account, that stroke is one of the leading causes of death or disability, any new way of predicting the risks of stroke and, therefore, preventing the disease, would be another efficient method of improving life quality and length. A new study suggests several new biomarkers that can actually be one of those new ways.
Stroke is a condition of brain cell death, which is caused by reduced blood flow to the brain, depriving it of oxygen. There are several risk factors that are known to cause stroke. Among them are high cholesterol level, high blood pressure and smoking. These factors are used in order to estimate the general risk level of stroke case.
The new study suggests four biomarkers in human blood. The level of these biomarkers can hint on increased or reduced risk of stroke. The study analyzed a number of participants who did not have a history of stroke. After nine years, a part of the participants did experience stroke. Basing on health condition before the stroke at all participants and on health conditions after the stroke at those participants who experienced it, the researchers noted four new inflammatory biomarkers that could influence the risk of stroke. The study did not take into account other health conditions that could influence the stroke risk, such as chronic disease or other risk factors. However, the researchers claim that the four new biomarkers could be associated with the stroke cases. These biomarkers are tumor necrosis factor, homocysteine, C-reactive protein and vascular endothelial growth.
Even though the study did not take into account many other stroke risk factors, the results are very promising and if these new biomarkers are included in the general screening for stroke risk estimation, the results can become even more accurate.
The main purpose of such studies is determining new ways of stroke risk prediction, which, eventually, leads to stroke prevention and improvement in life quality and length. That is why it is important to consider such studies in further investigations of stroke.
