Copenhagen Arterial Revascularization Randomized Patency and Outcome Trial - Full Text View

Sponsors and Collaborators:	Rigshospitalet, Denmark Danish Heart Foundation The Lundbeck Foundation Copenhagen Hospital Corporation
Information provided by:	Rigshospitalet, Denmark
ClinicalTrials.gov Identifier:	NCT00159991

Purpose

There is a remarkable lack of randomized trials concerning the potential benefit of using arterial conduits for coronary bypass surgery. This is the purpose of the present trial. Exclusive use of arterial conduits might result in improved conduit viability, reduced risk of recurrent angina, myocardial infarction and other cardiac events, reduced need for antianginal medication, improved functional status and possibly improved long term survival. The patients will be followed for ten years after surgery.

Primary Outcome Measures:

Angiographic distal anastomotic patency rates [ Time Frame: 1, 5 and 10 years postoperatively ] [ Designated as safety issue: No ]
Cardiac event free survival [ Time Frame: 1, 5 and 10 years postoperatively ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

Postoperative morbidity (frequency of peroperative/ postoperative infarction, arrythmias, use of IABP, inotropic support, pulmonary, renal and cerebral complications, length of stay in the ICU, etc. according to registration schemes). [ Time Frame: 3 months postoperatively ] [ Designated as safety issue: Yes ]
Risk of recurrent angina and need for antianginal medication [ Time Frame: 1, 5 and 10 years postoperatively ] [ Designated as safety issue: No ]
Data on functional status and social rehabilitation at clinical controls [ Time Frame: 3 months, 1, 5 and 10 years postoperatively ] [ Designated as safety issue: No ]

Eligibility

Ages Eligible for Study:	18 Years to 70 Years
Genders Eligible for Study:	Both
Accepts Healthy Volunteers:	No

Criteria

Inclusion Criteria:

Patients with 2 or 3 vessel coronary artery disease, where more than 1 coronary bypass graft is anticipated.
Elective or subacute operation (unstable AP with surgery within a few days)
Inclusion is independent of ventricular function, recent MI, degree and type of coronary lesions and secondary risk factors as diabetes, hyperlipidemia, hypertension, lung function, chronic obstructive lung disease, peripheral atherosclerotic disease, kidney function, earlier cerebrovascular disease.
Age: < 70 years.
Sufficient collateral blood supply to the hand by the ulnar artery, evaluated by the Allen test.
Patients must be able to give informed consent.

Exclusion Criteria:

Concurrent malignant disease with expected survival of < 5 years.
Unsuitable saphenous vein grafts evaluated preoperatively.
Unsuitable saphenous vein grafts with a diameter > 6mm evaluated preoperatively.
Acute operation (unstable hemodynamics in terms of need of inotropic support, ongoing MI with dynamic ECG changes, cardiogenic shock).
Concommitant operation for valve disease or other forms of heart surgery. Redo operations.
