Hypertension and Epistaxis: Why Is There Limited Guidance in the Nosebleed Clinical Practice Guidelines?

摘要

Hypertension has long been thought to influence the risk and severity of epistaxis. However, evaluation of the relevant literature reveals articles with methodologic concerns or limited quality. In many instances, these studies are not adequately controlled, and lack of multivariate analyses calls into question any noted association between epistaxis and hypertension. The goal of this commentary is to explain why there is limited guidance about the management of hypertension and the possible association with nosebleed in the 2020 American Academy of Otolaryngology-Head and Neck Surgery Foundation clinical practice guideline for nosebleeds. Background on the literature that describes the association between hypertension and nosebleeds is provided.
