Fig 1: Analysis of blood platelet activation markers in plasma samples. (A) The concentration of PF-4 [pg/mL] and (B) sP-selectin [pg/mL] were measured by the ELISA test in plasma from patients with ACS (n = 12) and healthy subjects (n = 12). The results were presented as the median with an interquartile range (Q1–Q3; whiskers—the minimum and maximum value, respectively). Statistical analysis was performed using the Mann–Whitney U test.
