Stent Thrombosis In Acute Coronary Syndromes

This is a multicenter registry that examines treatment strategies and outcomes in patients
who present with acute coronary syndrome (ACS) due to stent thrombosis in the coronary
arteries. This study will take place at potentially 8 medical centers throughout the State of
California. A total of 800 patients will be enrolled into the registry, 100 patients from
each of the eight participating California medical centers. UC Davis will serve as the core
lab for this study.

Eligible subjects, patients who present to the hospital (medical center) with ACS due to
stent thrombosis and receive a cardiac catheterization to treat the stent thrombosis, will be
included in the retrospective analysis of this cardiac condition. Subjects who expire in
hospital due to ACS with stent thrombosis will also be included in the retrospective analysis
of this clinical registry. Patients, who consent for approval, will become eligible to
participate in the 3-year prospective follow-up phase of the clinical registry. These
patients will be followed for three years to learn more about long term clinical outcomes for
this disease state.

There are no specific/special procedures required for this clinical registry. This is a
registry for data collection only to correlate prescribed medical care with individual short-
and long-term clinical outcomes.

Inclusion Criteria:

- Subject's age range will be ≥ 18 years old.

- Subjects will have an existing drug-eluting or bare metal stent.

- Subjects will have presented to the Medical Center with Acute Coronary Syndrome due to
stent thrombosis as identified via cardiac catheterization.

Exclusion Criteria:

- Inability to consent/declined to participate in the prospective arm of the clinical
registry.
