The original ROMICAT I (Rule out Myocardial Infarction with Computer-Assisted Tomography) consisted of 368 patients presenting with symptoms suggestive of acute coronary syndrome (ACS) to the ED. This secondary analysis evaluates the 183 patients with identifiable coronary artery disease (CAD) on CCTA, who had complete data for rest perfusion (rCTP) analysis. Sub-study analysis (n=81) was undertaken evaluating combined performance of rCTP/CCTA compared to combined performance of SPECT-MPI/CCTA.
