Further study details as provided by University of California, Davis:

Primary Outcome Measures:
  • To describe current real world practice in the treatment of ACS due to stent thrombosis. [ Time Frame: 3 years ]

Secondary Outcome Measures:
  • To describe early and long term follow up of patients who are treated for ACS due to stent thrombosis. [ Time Frame: 3 years ]

Estimated Enrollment: 800
Study Start Date: April 2008
Detailed Description:

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.
