Recently, the American Journal of Cardiology published the analysis of the first major record of phenotypes involved in DEAC among the American population, using data from the Nationwide Impatient Sample (NIS). Data from 66,360 patients diagnosed with SCAD between January 2004 and September 2015 was evaluated. 14 The average age was 61.3 ± 13.2 years and 44.2% were female. Depression was the most prevalent phenotype, which is why it was present in 5.15% of cases. Other causes frequently associated with SCAD, such as systemic vasculitis, Marfan syndrome, fibromuscular dysplasia, the use of steroids and corticosteroids, the abuse of cocaine or amphetamines, vasospasm, among others, were less prevalent 994
