Abstract

Background: Recurrent spontaneous coronary artery dissection (SCAD) is believed to be infrequent. Predictors of recurrent SCAD are poorly characterized. Methods: We evaluated the incidence, clinical characteristics, and predictors of recurrent SCAD using data from the Nationwide Readmissions Database from January 1, 2010, to December 30, 2016. Results: Among 1836 SCAD patients admitted with the primary diagnosis of SCAD (61.9% female, mean age 56.1 ± 14.5, 72.9% <65 years of age), 495 patients (26.9%) had recurrent SCAD within 1 year (74.0% female, 74% <65 years of age). Multivariable analysis showed that female sex (OR 2.09; 95% CI 1.49–2.95; p < 0.001) was an independent predictor of recurrent SCAD within 1 year. Conclusions: Recurrent SCAD is frequent and should be considered in younger females with a history of SCAD. Further research is needed to investigate the mechanistic links between female sex and recurrent SCAD.
