Insights
Blood biomarkers can help classify ischemic stroke causes faster than current methods. This review explores biomarkers for differentiating stroke mechanisms, aiding quicker therapeutic decisions.
Area of Science:
- Neurology
- Biochemistry
- Biomarker Discovery
Background:
- Stroke is a leading cause of death, with ischemic stroke accounting for 87% of cases.
- Accurate subtyping of ischemic stroke is crucial for effective treatment but current methods are time-consuming.
- Blood-based biomarkers offer a promising avenue for rapid and precise stroke mechanism classification.
Purpose of the Study:
- To review recent studies on blood-based biomarkers for differentiating ischemic stroke mechanisms.
- To discuss specific biomarkers and their potential cut-off values for classifying cardioembolic and atherosclerosis stroke.
- To present the concept of a point-of-care biosensor for on-site biomarker measurement.
Main Methods:
- Literature review of studies investigating blood-based biomarkers and ischemic stroke mechanisms.
- Analysis of specific biomarkers including b-type natriuretic peptide, d-dimer, inflammatory markers, and lipid profiles.
- Discussion of potential cut-off values for classification and a proposed biosensor device structure.
Main Results:
- Various blood biomarkers show potential in differentiating between ischemic stroke subtypes.
- Specific biomarkers like BNP, D-dimer, CRP, TNF-α, IL-6, IL-1β, NLR, cholesterol, triglycerides, HDL, LDL, and ApoA are discussed.
- Potential cut-off values are identified for classifying cardioembolic and atherosclerosis stroke.
Conclusions:
- Blood-based biomarkers can significantly improve the speed and accuracy of ischemic stroke classification.
- The development of point-of-care biosensors could enable rapid, on-site diagnosis and treatment decisions.
- Further research into these biomarkers and biosensor technology holds promise for enhancing stroke patient care.
Abstract:
Stroke is a top leading cause of death, which occurs due to interference in the blood flow of the brain. Ischemic stroke (blockage) accounts for most cases (87%) and is further subtyped into cardioembolic, atherosclerosis, lacunar, other causes, and cryptogenic strokes. The main value of subtyping ischemic stroke patients is for a better therapeutic decision-making process. The current classification methods are complex and time-consuming (hours to days). Specific blood-based biomarker measurements have promising potential to improve ischemic stroke mechanism classification. Over the past decades, the hypothesis that different blood-based biomarkers are associated with different ischemic stroke mechanisms is increasingly investigated. This review presents the recent studies that investigated blood-based biomarker characteristics differentiation between ischemic stroke mechanisms. Different blood-based biomarkers are specifically discussed (b-type natriuretic peptide, d-dimer, c-reactive protein, tumor necrosis factor-α, interleukin-6, interleukin-1β, neutrophil-lymphocyte ratio, total cholesterol, triglycerides, low-density lipoprotein, high-density lipoprotein and apolipoprotein A), as well as the different cut-off values that may be useful in specific classifications for cardioembolic and atherosclerosis etiologies. Lastly, the structure of a point-of-care biosensor device is presented, as a measuring tool on-site. The information presented in this review will hopefully contribute to the major efforts to improve the care for stroke patients.
