Study of ADAMTS-13 Activity, Von Willebrand Factor and Platelet-Monocyte Aggregation in Coronary Artery Disease

ADAMTS-13 Activity, Von Willebrand Factor and Platelet-Monocyte Aggregation in Patients Undergoing Percutaneous Coronary Intervention

The purpose of this research is to determine the relationship between proteins and enzymes in the blood and how they work with platelets to form blood clots in patients with coronary artery disease. The investigators hypothesize that the relationship between these factors could potentially be useful in identifying patients at higher risk for heart attacks.

Inclusion Criteria:
