The final cohort included 157 patients with SCAD. Of these, 135 (85.9%) had ‘definite’ SCAD diagnosed by their primary cardiologist and subsequently adjudicated by two physician reviewers; 14 (8.9%) had ‘possible’ SCAD with an alternate diagnosis (i.e., vasospasm, plaque erosion) equally likely; eight (5.0%) had ‘uncertain’ SCAD, which was documented in the EHR but further clinical information was not available for review.
