Name Time Method Main Objective: a) to determine whether clopidogrel is effective in reducing leukocyte activation existing in popcythemic patients; <br>b )to rule out a major increase of the bleeding risk due in patients treated with the combination therapy; and <br>c) to assess the prevalence of clopidogrel resistance in polycythemic subjects.;Secondary Objective: a) to assess the role of cytochrome P450 2C19 loss-of-function polymorphism in influencing the variability of platelet response to clopidogrel ;;Primary end point(s): nd
