Participant Flow

Additional 3000 patients were enrolled in the second enrollment phase and had completed phase I at 1 year. In phase II, 870 patients from these were transferred to AV-DAPT cohort and followed from 1 year to 33 months, and the remaining who did not participate in AV-DAPT cohort will be followed for the first year only.

Outcome measures of participants of XIENCE V USA trial of phase I followed up until 1 year from index procedure are available in the study with ID NCT00676520.

Second Enrollment Phase of XIENCE V® USA
Additional 3000 patients recruited in the second enrollment phase treated with the XIENCE V EECSS who are free from events (death, MI, repeat coronary revascularization, stroke, ST, or major bleeding - "severe" or "moderate" by GUSTO classification) in the first year after the index procedure, and are compliant with DAPT will be identified as prospective patients for the AV-DAPT cohort. A total of 870 Patients who are considered as part of the AV-DAPT cohort will continue with Aspirin therapy and will be randomized at 12 months post index procedure to 18 months of either active treatment with thienopyridines or placebo. Clinical follow-up will occur at 15, 24, 30 and 33 months. These patients will be followed by Abbott Vascular.
