Platelet Activity in Vascular Surgery
The proposed PIVOTAL study will examine a panel of platelet/coagulation activity markers
during the perioperative period. The goal is to develop a clinically useful assessment of
platelet/coagulation activity for risk stratification that may ultimately serve as a target
for therapeutic intervention. This study will enroll 200 patients with peripheral artery
disease undergoing vascular surgery. PIVOTAL is funded by American Heart Association and is
scheduled to begin enrollment in July 2013 for approximately two years.

To describe platelet activity among PAD subjects undergoing vascular surgery.
To determine whether preoperative platelet activity measurements are independently associated
with perioperative cardiovascular events.
To identify demographic, clinical, and surgical factors associated with postoperative
platelet activity measurements in patients with established PAD.
