Sudden Hearing Loss with Vertigo Portends Greater Stroke Risk Than Sudden Hearing Loss or Vertigo Alone

摘要

BackgroundBecause it is unknown whether sudden hearing loss (SHL) in acute vertigo is a “benign” sign (reflecting ear disease) or a “dangerous” sign (reflecting stroke), we sought to compare long-term stroke risk among patients with (1) “SHL with vertigo,” (2) “SHL alone,” and (3) “vertigo alone” using a large national health-care database.
