Association of Etoricoxib treatment and incident hypoxia in patients with aortic dissection undergoing endovascular aortic repair

Objective: The current study was to evaluate the association of Etoricoxib treatment and incident hypoxia among type-B aortic dissection (AD) patients undergoing endovascular aortic repair (EVAR). Methods: Patients undergoing EVAR were retrospectively recruited. Based on Etoricoxib use, patients were divided into the non-treated and Etoricoxib-treated groups. Baseline characteristics including demographics, laboratory parameters, characteristics of aortic computer tomography and echocardiography, medications used, and procedural characteristics were collected from the electronic health record. Results: Compared to non-treated group (n - 36), prevalence of obesity and fever at baseline was higher in Etoricoxib-treated group (n = 24; P < 0.05). Mean number of neutrophils, and mean serum CRP and D-dimer levels were higher in Etoricoxib-treated group (P < 0.05). The overall incidence of hypoxia was lower in Etoricoxib-treated group (44.4% vs 33.4%, P < 0.05). Increase in neutrophils count, serum CRP and D-dimer levels was associated with incident hypoxia, with an odds ratio (OR) of 1.36 (95% confidence interval [CI] 1.07-1.65), 1.44 (95% CI 1.12-1.78) and 1.25 (95% CI 1.01-1.47) respectively. In unadjusted model, Etoricoxib use was associated with a 44% lower odds of incident hypoxia. After adjustment for inflammatory markers, the association between Etoricoxib and incident hypoxia was non-significant, with OR of 0.95% and 95% CI of 0.78-1.06. Conclusion: Compared to patients who did not receive Etoricoxib during hospitalization, those treated with Etoricoxib had lower incidence of hypoxia, which might be attributed to its anti-inflammatory effects.

Automated summary

The study evaluated the association between Etoricoxib treatment and incident hypoxia among type-B aortic dissection patients undergoing endovascular aortic repair. Patients treated with Etoricoxib had lower incidence of hypoxia, potentially due to its anti-inflammatory effects.
