Further study details as provided by Brigham and Women's Hospital:

Primary Outcome Measures:
  • A composite of overt and occult GI bleeding, gastritis, and esophageal, gastric, or duodenal ulcerations. [ Time Frame: 90 Days ] [ Designated as safety issue: No ]
  • Overt GI symptoms include GI bleeding requiring hospitalization, blood transfusion, and/or interventions like endoscopy or surgery or gastroesophageal acid reflux (GERD) requiring acid-suppressive therapy. [ Time Frame: 90 Days ] [ Designated as safety issue: No ]
  • Occult GI ulcerations and erosions include those detected by capsule endoscopy (PillCamÒ ESO) within 80 to 90 days after initiation of dual antiplatelet therapy. [ Time Frame: 90 Days ] [ Designated as safety issue: No ]

Estimated Enrollment: 30
Study Start Date: April 2006
Estimated Study Completion Date: December 2008
Estimated Primary Completion Date: December 2007 (Final data collection date for primary outcome measure)
Intervention Details:
    Procedure: Video Capsule Endoscopy
    Noninvasive pill endoscopy is undertaken after 90 days of Aspirin/Clopidogrel in patients who have had percutaneous coronary intervention with drug-eluting stents.
