Predictive factors facilitate identification of potential aortic dissection in patients with obstructive sleep apnea syndrome

Objective: Investigating potential predictors of aortic dissection development in high-risk hypertensive patients with obstructive sleep apnea syndrome (OSAS). Methods: Hypertensive patients with aortic dissection, admitted to hospital between January 2010 and July 2020, was diagnosed with OSAS by overnight sleep study with polysomnography (PSG). Results: Male was liable to aortic dissection compared to female in both groups（84.7% and 86% respectively）.There were actually significant differences with regard to neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), mean platelet volume (MPV) / platelet count (PLT) ratio and D-dimer that we concerned about and were of great value in aortic dissection as previously reported. As multivariable regression analysis revealed, NLR (odds rate [OR], 2.258, 95% confidence interval [CI], 1.464-3.482, P
