[Ambulatory coronary angiography. Organization--patient safety--economic benefits].

916 (63%) of 1,452 coronary angiographies performed at the University Hospital in Trondheim from 1988 to 1990 were done policlinically. The study shows that coronary angiography can be carried out safely on an outpatient basis, and that more than 50% of all patients admitted for a coronary angiography can be examined in this way.
