Table 1 summarized the anthropometric and clinical features of all the patients. IL-33 was detectable in 12 (15.0%) patients and mean sST2 was 9.1 ± 4.4 ng/ml. 9 PsA patients had 15 previous cardiovascular (CV) events, including 6 cerebrovascular accidents, 4 transient ischemic attacks, and 5 ischemic heart diseases. The clinical characteristics of PsA patients without CV events were summarized in Supplementary Table 1. Here, IL33 is linked to transient ischemic attack.
