Study Characteristics


To assess the risks and benefits of drug-eluting stents (DES) versus bare-metal stents (BMS) in de-novo saphenous vein bypass graft (SVG) lesions.

Era of Service



Patients 18 years and older who have had at least one significant de-novo SVG lesion requiring percutaneous coronary intervention (PCI) with intent to use embolic protection devices.

Study Design

Randomized, parallel, triple-blind clinical trial


  • Arm 1 (Active Comparator): BMS in the SVG lesion(s)
  • Arm 2 (Experimental): DES in the SVG lesion(s)

Time Period

January 2012 - December 2016




597 participants

Response Rate


Recruitment Method

  • Patients were recruited from 25 VA medical centers
  • All patients with prior coronary artery bypass graft surgery scheduled to undergo coronary angiography and/or percutaneous intervention to a SVG were screened


$25 for each in-person follow-up visit (up to $175)

Data Collected

Primary outcome

  • 12-month incidence of target vessel failure (TVF), defined as a composite of: cardia death, target vessel myocardial infarction, and target vessel revascularization

Secondary outcome

  • Clinical outcomes other than target vessel failure, including procedural success/complications, all-cause and cardiac death, follow-up myocardial infarction, stent thrombosis, target lesion/vessel revascularization, target and non-target vessel revascularization, stroke
  • Composite endpoint of any death, any myocardial infarction and target vessel revascularization (patient-oriented composite endpoint)
  • Incremental cost-effectiveness of DES relative to BMS 

Tertiary outcome

  • In-stent neointima proliferation as measured by intravascular ultrasonography

Other assessments

  • Demographics and medical history
  • Physical examination, electrocardiogram, laboratory tests, cardiac enzymes, graft angiography and PCI
  • Quality of life

Data Collection Methods

Study coordinators collected data from patients for the study forms via in-person or phone interviews. For in-person visits, a brief physical examination was performed. Clinical data were obtained from the participants’ medical records. Sites entered patient data directly into a web-based database.
