Considering the demonstrated effect that extracellular vesicles (EVs) have on regulating inflammatory processes, coagulation, and angiogenesis, the present study aims to characterize plasma EVs and their relationship with coagulation disorders in patients with CCC. A total of 78 patients were assessed with 46.1% (36\/78) representing the CCC group, 8.9% (7\/78) with cardiomyopathy unrelated to Chagas disease (CM group), and 44.8% (35\/78) comprising the control group, which included individuals without cardiomyopathy and negative for T. cruzi infection. Plasma EVs concentration (EVs\/mL) for each individual was evaluated by flow cytometry, along with the proportion of EVs expressing PSGL-1 (PSGL-1+ EVs), Tissue Factor (TF\u2009+\u2009EVs), and CD41a (CD41a\u2009+\u2009EVs). The ability of EVs to induce platelet aggregation was evaluated by spectrophotometry. We also evaluated other prothrombotic biomarkers, including platelet count, activated partial thromboplastin time (PTT), prothrombin time (PT), and D-dimer levels. The results revealed elevated D-dimer levels in the CCC group, accompanied by a decrease in the count of EVs per mL of plasma and a significant increase in the proportion of PSGL-1+ EVs ( P\u2009&lt;\u2009.05) compared to the control group. Other parameters did not exhibit significant differences between groups. The elevated levels of PSGL-1+ EVs in the CCC group may be attributed to myocardial inflammatory processes, which, upon interaction with platelet-derived P-selectin, could promote thrombus formation, as indicated by the increased D-dimer levels in this group.<\/jats:p>","DOI":"10.1177\/10760296241295742","type":"journal-article","created":{"date-parts":[[2024,11,4]],"date-time":"2024-11-04T01:23:56Z","timestamp":1730683436000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Assessment
