Abstract:
Microparticles, also termed extracellular vesicles (EVs) are novel candidate markers of platelet activation and ongoing inflammation in vivo. Different subtypes of EVs are released from platelets, endothelial cells and leukocytes. Blood concentration of EV subtypes in patients with acute myocardial infarction, stroke and peripheral artery disease correlated with the severity of the disease. Accumulating data indicate that EVs may contribute to the development of atherosclerosis and its complications. Measurement of EV concentrations might become an element of minimally-invasive diagnostic tests, allowing for early diagnosis of cardiovascular disease (CVD), risk stratification and monitoring of therapy in patients with high cardiovascular risk. It also may allow to monitor the response to antiplatelet therapy with acetylsalicylic acid or P2Y12 antagonists. Isolation and detection of EVs have been recently standardized, allowing for further development of research on these promising biomarkers. EV-based tests might eventually be implemented into every-day clinical practice as well as in multicenter clinical trials.
Insights
Extracellular vesicles (EVs), or microparticles, signal platelet activation and inflammation. Measuring EVs aids early cardiovascular disease diagnosis, risk assessment, and therapy monitoring.
Area of Science:
- Cardiovascular Research
- Biomarker Discovery
- Hematology
Background:
- Microparticles, also known as extracellular vesicles (EVs), are emerging biomarkers for platelet activation and inflammation.
- Various EV subtypes originate from platelets, endothelial cells, and leukocytes.
- Elevated EV concentrations in patients with acute myocardial infarction, stroke, and peripheral artery disease correlate with disease severity.
Purpose of the Study:
- To explore the role of EVs as diagnostic and prognostic markers for cardiovascular diseases (CVD).
- To evaluate the potential of EV measurement in risk stratification and therapy monitoring for high-risk patients.
- To assess the utility of EVs in monitoring responses to antiplatelet therapies.
Main Methods:
- Standardized methods for EV isolation and detection have been developed.
- Correlation analysis between EV subtypes and disease severity in CVD patients.
- Evaluation of EV concentration changes in response to antiplatelet therapy.
Main Results:
- Blood EV concentrations correlate with disease severity in acute myocardial infarction, stroke, and peripheral artery disease.
- EVs are implicated in the pathogenesis of atherosclerosis and its complications.
- Standardization of EV measurement facilitates further research and clinical application.
Conclusions:
- EV measurement holds promise for minimally-invasive early diagnosis, risk stratification, and monitoring of CVD.
- EV-based tests may guide therapy selection and monitor treatment response, including antiplatelet agents.
- Standardized EV detection paves the way for clinical implementation in routine practice and trials.

Structure and Function of Platelets
Platelets are continually replenished, circulating in the bloodstream for 9-12 days before being removed by phagocytes, primarily in the spleen. A microliter of circulating blood contains between 150,000 and 450,000...
