Causes, Trends and Predictors of 90-Day Readmissions After Spontaneous Coronary Artery Dissection (From A Nationwide Readmission Database)

Abstract Spontaneous coronary artery dissection (SCAD) is a frequently missed diagnosis in patients presenting with acute coronary syndrome (ACS). Our aim was to evaluate the causes, trends and predictors of 90-day hospital readmission in patients presenting with SCAD. The Nationwide Readmissions Database (2013-2014) was utilized to identify patients with primary discharge diagnosis of SCAD using the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9, CM), diagnostic code 414.12. The primary outcome was 90-day readmission. Among 11,228 patients admitted with the primary diagnosis of SCAD, 2,424 patients (21.6%) were readmitted within 90 days (68% female, 82%
