Relationship between orthostatic hypotension and recurrence of benign paroxysmal positional vertigo, 2022, Moon Jung Kim

Blood pressure is maintained by a combined mechanism of the baroreceptor reflex and the vestibulosympathetic reflex. This study is intended to verify the hypothesis that the orthostatic hypotension (OH) seen when benign paroxysmal positional vertigo (BBPV) occurred may act as a factor that affects the recurrence BPPV.

The subjects of present study were selected from among 239 patients diagnosed with idiopathic BPPV. The average age of the group with OH was 59.3 years, and the age of the group w/o Oh was 50.3 years, with a statistically significant difference (P=0,013). It was shown that drug-taking increased the risk of OH occurrence by 4.08 times (C.I for exp(B): 1.20-13.77) compared to the group that did not take drugs. It was shown that the risk of recurrence of BPPV was significantly reduced in the no recurrence group compared to the multiple recurrence group when there was no OH (p=0.000; aOR 0.0000002).

the study is the first study that studied the effect of OH on the recurrence of BPPV and showed the possibility that OH could partially influence the recurrence BPPV.
