ABSTRACT
OBJECTIVES: Spontaneous coronary artery dissection (SCAD) may contribute to 35% of acute coronary syndrome among women ≤50 years of age. We aimed to investigate the overall incidence, as well as the trends of SCAD incidence based on race, household income, and the U.S. census regions utilizing the National Inpatient Sample.
METHODS: This is a retrospective cohort study, where discharge data were extracted from the NIS using 9th and 10th revisions of the International Classification Disease for SCAD.
RESULTS: : We found that the incidence of SCAD is rising, and patients were predominantly females. Crude incidence of SCAD per 1,000,000 discharges per year was found to be 4.95 (2010), 5.73 (2011), 5.34 (2012), 6.18 (2013), 7.64 (2014), 8.11 (2015), 14.58 (2016), and 14.81 (2017). Statistically significant differences were observed in year-to-year SCAD incidence among racial groups, household income quintiles, and U.S. census regions (P<0.0001).
CONCLUSION: : Recent trends (2017) indicate the highest incidence is among the White race, highest household income quintile, and in Census Region 4. These findings defy racial trends in cardiovascular disease burden which need further discovery.
