We commonly encounter patients with epistaxis who are found to be hypertensive. Some have taught over the years that hypertension causes nosebleeds and that some nose bleeds won't stop until the BP is lowered...
Some pearls about HTN/Epistaxis:
Most patients we see with hypertension are not experiencing epistaxis, casting serious doubt on a causal relationship
Studies show that the degree of blood pressure elevation does not correlate with risk of nose bleed
No studies have ever shown that acute BP reduction in the ED for a nose bleed is beneficial or reduces bleeding
Much of the debate is sparked by our ENT colleagues who swear that hypertension leads to nose bleeds and that bleeding will not stop until the BP is "treated." Much of this is based on experience with patients in the OR or IR suite. These blood pressures tend to be treated with IV antihypertensives by the ENT folks, and they feel pretty strongly about this relationship.
