Platelet expression of CD62P in patients receiving extracorporeal membrane oxygenation (ECMO) compared to controls. CD62P expression was analyzed by flow cytometry on resting (baseline), thrombin receptor activating peptide (TRAP)-stimulated and adenosine diphosphate (ADP)-stimulated platelets. Blood was sampled from ECMO patients on day1, day 3 and after ECMO explantation (Post). CD62P expression on platelets was compared to healthy controls (Healthy) and patients with coronary artery disease (CAD). a, Baseline CD62P expression was similar in ECMO patients and controls. CD62P expression in response to TRAP (b) and ADP (c) stimulation was lower in ECMO patients. The number of ECMO patients remaining at each time point and the number of control patients are indicated below. Data are presented as mean ± standard error of the mean. ns, not significant, *p < 0.05, **p < 0.01, ***p < 0.001
