Our aim was to evaluate the correlation of inter arm systolic blood pressure difference (IASBPD), inter leg systolic blood pressure difference (ILSBPD), and ABI with acute aortic dissection (AAD) and their role in predicting AAD. Methods: In this prospective case-control study, 180 patients with AAD admitted to the emergency department were prospectively and consecutively collected in Tongji Hospital from October 2019 to December 2020. 180 healthy people matched by sex, age and BMI served as control group. All participants were adults over 18 years of age who underwent four-limb blood pressure measurements. IASBPD, ILSBPD and ABI were compared between the two groups and their associations with AAD were analyzed. Results: A total of 360 patients (180 cases and 180 controls) were analyzed. In case group IASBPD was larger [(15.23 \u00b1 16.15) mm Hg vs. (4.19 \u00b1 3.63) mm Hg] and ILSBPD was larger (13.00 mm Hg vs. 5.70 mm Hg). ABI was smaller [(0.98 \u00b1 0.24) vs. (1.12 \u00b1 0.09)], and the difference was statistically significant (all p &lt; 0.05). According to the receiver operating characteristic curve (ROC), IASBPD \u226510 mm Hg (Sen 61.7%, Spe 88.9%), ILSBPD \u226513 mm Hg (Sen 50.6%, Spe 80.6%) and ABI \u22640.9 (Sen 53.3%, Spe 87.2%), showed significant correlation with AAD (all p &lt; 0.001). Conclusions: Compared with healthy people, IASBPD and ILSBPD levels were higher and ABI levels were lower in patients with AAD. IASBPD \u226510 mm Hg and ILSBPD \u226513 mm Hg can be used as indicators for early screening of AAD, and IASBPD \u226510 mm Hg has better predictive value for the occurrence of AAD. In patients with typical chest pain, attention needs to be paid to measuring blood pressure in the extremities.<\/jats:p>","DOI":"10.31083\/j.rcm2401009","type":"journal-article","created":{"date-parts":[[2023,1,9]],"date-time":"2023-01-09T08:26:04Z","timestamp":1673252764000},"source":"Crossref","is-referenced-by-count":1,"title":["The Predictive Value of Inter Arm Blood Pressure Difference, Inter Leg Blood Pressure Difference and Ankle Brachial Index for Acute Aortic Dissection"],"prefix":"10.31083","volume":"24","author":[{"given":"Quan","family":"Zhou","sequence":"first","affiliation":[{"name":"Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology, 430030 Wuhan, Hubei, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sufang","family":"Huang","sequence":"first","affiliation":[{"name":"Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology, 430030 Wuhan, Hubei, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"16242","published-online":{"date-parts":[[2023,1,4]]},"reference":[{"key":"ref1","doi-asserted-by":"crossref","unstructured":"Nazerian P, Giachino F, Vanni S, Veglio MG.
