Scientific title	An observational prospective follow-up study of radial artery coronary bypass grafting in North Norway
Study acronym	RABAGAST
Study objectives	1. Radial artery is better than vein as coronary bypass grafts 2. Arterial grafts induce less native disease progression than vein grafts
Ethics approval(s)	Not provided at time of registration
Health condition(s) or problem(s) studied	Coronary artery disease
Intervention	The treatment is coronary artery bypass grafting. All patients receved radial artery grafts, most also recevied internal mammary artery and saphenous vein grafts. Planned follow-up is at least 10 years.
Intervention type	Other
Primary outcome measure	1. Survival 2. Graft patency 3. Disease progression Outcomes will be measured at approximately 10 years after the index operation.
Secondary outcome measures	1. Recurrent angina 2. Infarction 3. Endothelial function Outcomes will be measured at approximately 10 years after the index operation.
Overall study start date	01/09/2010
Completion date	31/12/2011
