Although powerful in clinical setting, search for new markers is warranted as early diagnosis of MI is associated with improved outcomes. Extracellular vesicles (EVs) attracted considerable interest as new blood biomarkers. A training cohort used for diagnostic modelling included 30 patients with STEMI, 38 with stable angina (SA) and 30 matched\u2010controls. Extracellular vesicle concentration was assessed by nanoparticle tracking analysis. Extracellular vesicle surface\u2010epitopes were measured by flow cytometry. Diagnostic models were developed using machine learning algorithms and validated on an independent cohort of 80 patients. Serum EV concentration from STEMI patients was increased as compared to controls and SA. EV levels of CD62P, CD42a, CD41b, CD31 and CD40 increased in STEMI, and to a lesser extent in SA patients. An aggregate marker including EV concentration and CD62P\/CD42a levels achieved non\u2010inferiority to troponin, discriminating STEMI from controls (AUC\u00a0=\u00a00.969). A random forest model based on EV biomarkers discriminated the two groups with 100% accuracy. EV markers and RF model confirmed high diagnostic performance at validation. In conclusion, patients with acute MI or SA exhibit characteristic EV biomarker profiles. EV biomarkers hold great potential as early markers for the management of patients with MI.<\/jats:p>","DOI":"10.1111\/jcmm.15594","type":"journal-article","created":{"date-parts":[[2020,7,15]],"date-time":"2020-07-15T00:42:16Z","timestamp":1594773736000},"page":"9945-9957","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":42,"title":["An
