Observational Study
Comparative Effectiveness of Routine Invasive Coronary Angiography for Managing Unstable Angina.
Non-ST-segment elevation acute coronary syndromes include unstable angina and non-ST-segment elevation myocardial infarction.

Consequently, no clear, specific recommendations exist regarding the use of angiography in unstable angina. ⋯ National Health and Medical Research Council, Australia and BUPA Health Foundation.
