A Study of the Association between Epistaxis and the Severity of Hypertension

Abstract

Hypertension (HTN) has frequently been cited as a general risk factor for epistaxis. However, studies dealing with this association have yielded equivocal results. In this study, a sample of 121 hypertensives (blood pressure ≥ 140/90 mmHg) was selected to evaluate the association between the severity of HTN and a previous history of epistaxis. Patients with an average blood pressure ≥ 160/100 mmHg were classified as suffering from a more severe form of HTN and were compared with those with a less severe form of the disease (160/100 mm Hg ≤ blood pressure ≥ 140/90 mm Hg). The frequency of epistaxis did not differ among patients categorized by the severity of HTN. Users of aspirin were found to be twice as likely to have a history of epistaxis. In addition, there was a statistical tendency for an association between a history of epistaxis and the duration of hypertension. We conclude that the severity of HTN and a history of epistaxis were not associated in a cohort of hypertensive patients. The identification of other risk factors for epistaxis, including the duration of HTN, deserves further study.
