Platelet Reactivity In Patients With Nuisance Bleeding On A Thienopyridine
Completed
Conditions studied: Platelet Aggregation, Bleeding
In brief
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.
