Platelet Reactivity In Patients With Nuisance Bleeding On A Thienopyridine

The objective is to describe and quantify levels of platelet reactivity in three different
cohorts of patients taking thienopyridine: patients who report nuisance bleeding, patients
who report alarming bleeding, and patients who report no nuisance or alarming bleeding. The
investigators hypothesize that patients with nuisance or alarming bleeding events on
maintenance thienopyridine therapy will have lower levels of platelet reactivity than
patients without nuisance or alarming bleeding on thienopyridine therapy.
