Spontaneous coronary artery dissection (SCAD) can present with various clinical symptoms,
including chest pain, syncope, and sudden cardiac death, particularly in those without
atherosclerotic risk factors. In this contemporary analysis, we aimed to identify
the causes and predictors of 30-day hospital readmission in SCAD patients. We utilized
the latest Nationwide Readmissions Database from 2016 - 2017 to identify patients
with a primary discharge diagnosis of SCAD. The primary outcome was 30-day readmission.
Among 795 patients admitted with a principal discharge diagnosis of SCAD, 85 (11.3%)
were readmitted within 30 days of discharge from index admission (69.8% women, mean
age of 54.3 ± 0.8). More than half of the readmissions (57%) were cardiac-related
readmissions. Common cardiac causes for 30-day hospital readmission were acute coronary
syndrome (27.3%), chest pain/unspecified angina (24.6%), heart failure (17.5%), and
recurrent SCAD (8.3%). In conclusion, we found that following hospitalization for
SCAD, almost one-tenth of patients were readmitted within 30 days, largely due to
cardiac cause . Risk stratifying patients with SCAD, identifying high-risk features
or atypical phenotypes of SCAD, and using appropriate management strategies may prevent
hospital readmissions and reduce healthcare-related costs. Further studies are warranted
to confirm these causes of readmission in SCAD patients.
