Cardiovascular risk factors and hearing impairment: a non-automatic correlation
Hearing, Balance and Communication, 2016
Background: In the literature the association between common cardiovascular risk factors and/or major events and inner ear diseases has been widely considered. Despite the controversial related results, a recent review underlines that while a direct and causal correlation between cardiovascular risk factors and hearing impairment is lacking, the former are thought to have an influence on hearing acuity: this should imply some correlation between arterial conditions and inner ear function. Aims: Aiming at verifying the reliability of the correlation between arterial conditions and inner ear function, the hearing function of a population with metabolic syndrome and a population without metabolic syndrome were matched. Methods: All the examined subjects were enrolled within the Brisighella Heart Study, in order to obtain a detailed knowledge of the cardiovascular and metabolic parameters. 142 subjects were enrolled, including 89 healthy subjects and 53 affected by metabolic syndrome, having ruled out those cases associated with external and/or middle ear pathologies, or unilateral sensorineural hearing loss or with a history of previous ototoxic drugs and ear surgery. Among the examined parameters was arterial stiffness, as evaluated by means of the VicorderV R device with a noninvasive procedure, which had not previously been considered in relation to labyrinthine function. Results: The lack of any statistically significant correlation between common cardiovascular risk factors and hearing deterioration, as emerged from the study, has a particular significance. Conclusions: The inference from this result is that the relationship between the systemic circulation and inner ear conditions must be more complex than frequently considered.

The purpose of this study is to support the hypothesis that diabetic end-organ damage of the cochlea is augmented in the setting of hypertension. A historical perspective reviewing the effects of diabetes and hypertension as causative factors in the development of sensorineural hearing loss, as well as the basic epidemiology and pathophysiology of the renal and vascular effects of diabetes and hypertension, is presented. The results of audiologic findings in insulin-dependent diabetic patients, both normotensive and hypertensive, were analyzed and correlated with the results of animal studies to support the hypothesis that sensorineural hearing loss in patients and cochlear hair cell loss in animal studies result from the effects of hypertension in conjunction with insulin-dependent diabetes mellitus.
Hearing loss and hypertension: exploring the linkage
The Egyptian Journal of Otolaryngology, 2021
Background The inner ear vascular system may be disrupted by systemic hypertension causing inner ear hemorrhage and resulting in progressive or sudden hearing loss. Constriction of the labyrinthine artery secondary to atherosclerosis seen in high BMI and waist/hip circumference—risk factors of hypertension—could also occur with resultant hearing loss. Thus, hypertension could predispose to increased risk of hearing loss. This cross-sectional study assessed the hearing thresholds of hypertensive patients and sought to determine the association between hypertension and hearing loss among patients attending cardiology clinic in tertiary hospital in Nigeria. Results The study population was 500 individuals equally divided into subject and control arms. The mean age of the subjects and controls was 47.2 ± 7.4 years and 46.9 ± 7.5 years respectively. Hearing loss—mainly mild sensorineural hearing loss—was seen in 30% of the subjects and 0.4% of the controls. The hearing loss was bilateral...
Cardiovascular risk factors and hearing loss: The HUNT study
International Journal of Audiology, 2015
Objective: The purpose of the present paper was to examine the association between prospectively and cross-sectionally assessed cardiovascular risk factors and hearing loss. Design: Hearing was assessed by pure-tone average thresholds at low (0.25-0.5 kHz), middle (1-2 kHz), and high (3-8 kHz) frequencies. Self-reported or measured cardiovascular risk factors were assessed both 11 years before and simultaneously with the audiometric assessment. Cardiovascular risk factors were smoking, alcohol use, physical inactivity, waist circumference, body mass index, resting heart rate, blood pressure, triglycerides, total serum cholesterol, LDL cholesterol, HDL cholesterol, and diabetes. Study sample: A population-based cohort of 31 547 subjects. Results: After adjustment for age, sex, level of education, income, recurrent ear infections, and noise exposure, risk factors associated with poorer hearing sensitivity were smoking, diabetes, physical inactivity, resting heart rate, and waist circumference. Smoking was only associated with hearing loss at high frequencies. The effects were very small, in combination explaining only 0.2-0.4% of the variance in addition to the component explained by age and the other cofactors. Conclusion: This cohort study indicates that, although many cardiovascular risk factors are associated with hearing loss, the effects are small and of doubtful clinical relevance.
Hypertension as a Risk Factor of Hearing Loss
2014
Hearing loss is a factor that affects the quality of life of people and it may make oral language receiving difficult. Studies confirm that hearing changes may derive from arterial hypertension. So the study was undertaken to evaluate hypertension as a risk factor of hearing loss. The study was carried out in the Department of Physiology in collaboration with the Department of ENT and Department of Medicne, IMS and SUM Hospital, Bhubaneswar, Odisha, India. In this study, 150 cases and 150 controls groups were taken both genders aged 45-64 years. Hypertension was verified through blood pressure readings by sphygmomanometer, and by systematized questionnaire about hypertension and use of medication for hypertension. Hearing loss was assessed through pure tone audiometry. Only sensory neural deafness was taken. Statistical analysis was made. There is significant risk factor of hearing loss because of hypertension. Hearing loss population under study suggests that hypertension is an acc...
Probable Association of Hearing Loss, Hypertension and Diabetes Mellitus in the Elderly

Introduction The aging process causes changes in body structure in a continuous manner, and contributes to clinical disorders. Life expectancy is increasing, especially in developing countries. Objective To assess the prevalence of hearing loss and its possible association with hypertension and diabetes mellitus (DM) in the elderly. Methods A cross-sectional study with 519 elderly individuals aged over 60 years who underwent an audiological evaluation (pure tone audiometry), and answered a comorbidity questionnaire that included questions about age, gender, tinnitus and medical history, with data concerning DM. The dependent variable was the presence of hearing loss. The independent variables were age, gender, DM and hypertension. The variables were presented in absolute numbers and proportions, and enabled us to estimate the prevalence. The statistical analysis was performed through multiple logistic regression with 95% confidence intervals and values of p < 0.05 for the hearing...
Association Between Hypertension and Hearing Loss

Introduction Hypertension (HTN) is a common health problem, diagnosed in every one out of four individuals. It is associated with various complications; however, its impact on hearing loss is not well studied. In this study, we will determine the impact of HTN on hearing. Methods This cross-sectional study was conducted in Jinnah Sindh Medical University from August 2020 to March 2021. Three hundred (300) patients with documented diagnosis of HTN, between the ages of 21 and 50 years, were enrolled in the study. Another 300 non-hypertensive participants were enrolled as a reference group. Participants were sent to trained otolaryngologist technicians, who performed audiometry at six different frequencies for each year (0.5, 1.0, 2.0, 3.0, 4.0, and 6.0 kilohertz (kHz)). The final hearing level was calculated by taking mean of hearing levels of both ears. Results The hearing levels in audiometry were significantly higher in hypertensive participants compared to nonhypertensive participants (23.4 ± 8.67 dB vs 18.3 ± 6.02 dB; p-value: <0.0001). Participants who had been diagnosed with HTN for more than five years had higher hearing levels in audiometry test compared to participants with less than five years of HTN (24.21 ± 8.92 dB vs. 22.6 ± 8.02 dB; p-value 0.0001). Conclusion Based on our study, HTN is positively correlated with hearing loss. Therefore, longstanding hypertensive patients should be screened regularly in order to assess the status of their hearing abilities.
Effects of diabetes mellitus and systemic arterial hypertension on elderly patients’ hearing
Brazilian Journal of Otorhinolaryngology, 2017
Introduction: Chronic diseases can act as an accelerating factor in the auditory system degeneration. Studies on the association between presbycusis and diabetes mellitus and systemic arterial hypertension have shown controversial conclusions. Objective: To compare the initial audiometry (A1) with a subsequent audiometry (A2) performed after a 3 to 4-year interval in a population of elderly patients with diabetes mellitus and/or systemic arterial hypertension, to verify whether hearing loss in these groups is more accelerated when compared to controls without these clinical conditions. Methods: 100 elderly individuals participated in this study. For the auditory threshold assessment, a previous complete audiological evaluation (A1) and a new audiological evaluation (A2) performed 3-4 years after the first one was utilized. The participants were divided into four groups: 20 individuals in the diabetes mellitus group, 20 individuals in the systemic arterial hypertension group, 20 individuals in the diabetes mellitus/systemic arterial hypertension group and 40 individuals in the control group, matching them with each study group, according to age and gender. ANOVA and Kruskal-Wallis statistical tests were used, with a significance level set at 0.05.
