title: Active epistaxis at ED presentation is associated with arterial hypertension.
abstract: Epistaxis and hypertension are frequent in the general population, but an association is still controversial. Aim of this retrospective cohort study was to test if active epistaxis at emergency department (ED) presentation is associated with hypertension. Patients with active epistaxis at ED presentation (n = 271; 73%) were compared with controls without active bleeding (n = 101; 27%). By multivariate logistic regression modeling we found that active epistaxis was independently associated with history of hypertension (odds ratio 2.8 [95% CI 1.4 to 5.6; P =.004] adjusted for age, gender, rhinitis, diffuse bleeding, and malignant diseases). Patients with active epistaxis had higher blood pressure at presentation compared with controls (systolic blood pressure 165 v 153 mmHg, P <.001, diastolic blood pressure 85 v 77 mmHg, P <.001). Active epistaxis at ED presentation is associated with arterial hypertension.
