This is the first randomized controlled trial to compare the effectiveness of a functional test versus angiography by tomography (≥64 cuts) to diagnose coronary artery disease. The study included 10003 patients from 193 centers who were symptomatic but no previous diagnosis of coronary artery disease.
The study found no difference in prognosis between patients who received a functional test versus those who received angiography so this latter, was established as a valid alternative. The analysis of the radiation dose received and the rate of subsequent studies favored the scan.
