Figure 4

Maximal light transmission, i.e. platelet aggregation in platelet-rich plasma from healthy control subjects (A), CAD patients treated with ASA alone (B), and clopidogrel responders (C) and low-responders (D) among CAD patients treated with ASA and clopidogrel. The following agonist/antagonist concentrations were used: 32 µM TRAP, 6.5 µM ADP, 50 µM serotonin, 10 µM ketanserin. * p<0.05 and ** p<0.01 in ANOVA followed by Bonferroni's multiple comparison test.
