The audiological profile of adults with and without hypertension

Abstract

OBJECTIVE:To determine whether there is any influence of systemic arterial hypertension on the peripheral auditory system.METHODS:This was a cross-sectional study that investigated 40 individuals between 30 and 50 years old, who were divided into groups with and without systemic arterial hypertension, using data from high-frequency audiometry, transient-evoked otoacoustic emissions and distortion-product otoacoustic emissions. The results were compared with those from groups of normal-hearing individuals, with and without systemic arterial hypertension, who underwent the pure-tone audiometry test. All individuals also underwent the following procedures: otoscopy, acoustic immittance measures, pure-tone audiometry at frequencies from 250 to 16000 Hz, transient-evoked otoacoustic emissions test and distortion-product otoacoustic emissions test.RESULTS:No statistically significant difference was observed between the groups with and without systemic arterial hypertension in either conventional or high-frequency audiometry. Regarding transient-evoked otoacoustic emissions, there was a trend toward statistical significance whereby the systemic arterial hypertension group showed lower results. Regarding distortion-product otoacoustic emissions, the systemic arterial hypertension group showed significantly lower results at the following frequencies: 1501, 2002, and 3003 Hz. A discriminant analysis indicated that the distortion-product otoacoustic emissions variables best distinguished individuals with and without systemic arterial hypertension.CONCLUSION:Data from this study suggest cochlear dysfunction in individuals with systemic arterial hypertension because their otoacoustic emission results were lower than those in the systemic arterial hypertension group.

Guanylyl Cyclase A/cGMP Signaling Slows Hidden, Age- and Acoustic Trauma-Induced Hearing Loss

“…GC-A KO mice develop arterial hypertension (Kuhn, 2005). Whether arterial hypertension itself may contribute to agerelated hearing loss is still controversial (Przewozny et al, 2015;Soares et al, 2016;Reed et al, 2019). Although we cannot exclude the possibility that glucose metabolism may be altered in the GC-A KO mice, and consequently affect hearing, other mouse mutants with hypertension (NO-GC KO mice) have normal and persisting hearing function (Friebe et al, 2007;Möhrle et al, 2017).…”

Evaluation of Differential Sensitivity for Frequency, Intensity, and Duration in Individuals with Hypertension

“…They revealed a significant relationship between HTN and hearing loss by using a questionnaire on hearing loss and correlated it with blood pressure reading and a poorer pure tone threshold. Soares et al 10 examined the audiological profile of adults with and without HTN using transient-evoked otoacoustic emissions (TEOAEs) and reported a lower TEOAE amplitude in individual with HTN.…”

“…Metabolic disorders can affect cochlear physiology in several stages of the transduction of mechanical information (sound) into electrical information (neural), at least temporarily [8][9][10]. In the gestational period it is noteworthy the presence of high prevalence pathologies that generate characteristic metabolic disorders such as Diabetes Mellitus [11][12][13] and Hypertensive Syndromes [14][15][16], which can generate hearing impairment.…”
