![]() We also excluded patients with previous history of specific hearing disorders (such as rubella and head injuries), specific metabolic disorders (such as diabetes) and specific vascular disorders (such as strokes), and also individuals who worked or had worked in an environment that could cause noise-induced hearing loss, patients with kidney diseases and with prior history of hospital stay or ingestion of potentially ototoxic medication or drugs were also taken off the study. Subjects with air-borne gap of more than 10 db were also excluded from our study. Those patients who were wearing hearing aids and those who were undergoing treatment for any neurologic disorders, were also excluded from our study. The patients outside this age group were excluded from the study leaving 246 patients. The results attained with the present research project will certainly serve as basis for a greater integration between cardiologists, nephrologists, otorhinolaryngologists, speech therapists and other health care professionals involved with arterial hypertension and hearing loss care, bringing about relevant data for the professionals involved in order to improve quality of care in the therapy and rehabilitation of these patients.ģ75 patients with diagnosed hypertension were selected randomly, who were receiving care at our tertiary care hospital for any reason between the age group of 45 and 64 years. ![]() Moreover, arterial hypertension may cause ionic changes in cell potentials, thus causing hearing loss. One of the vascular physiopathological mechanisms described is the increase in blood viscosity, which reduce capillary blood flow and ends up reducing oxygen transport, causing tissue hypoxia, thus causing hearing complaints and hearing loss in patients. This circulatory system pathology may directly affect hearing in a number of ways. High pressure in the vascular system may cause inner ear hemorrhage, which is supplied by the anterior inferior cerebellar artery, which supports the inner ear artery and is divided into cochlear artery and anterior vestibular artery, which may cause progressive or sudden hearing loss. Hypertension, the most common vascular disorder, may facilitate structural changes in the heart and blood vessels. Katz says that all living cells in the human body depend on a proper supply of oxygen and nutrients in order to maintain their function, and such supply depend on the functional and structural integrity of the heart and blood vessels. Moreover, it is estimated that about half of the deaths of patients above 50 years are due to cardiovascular diseases, and 80 % of them have high blood pressure. Few diseases are responsible for so frequent and severe complications as the ones accruing from Arterial Hypertension: stroke, heart, kidney and peripheral vascular insufficiencies. The relevance of Arterial Hypertension as a human disease is due to its clinical complications, morbidity and mortality, as well as the heavy burden to the patient, family and public. This is due to a number of factors, such as intense and/or continuous noise exposure, inhalation of toxic substances, ingestion of ototoxic drugs, metabolic and circulatory alterations, infections, different types of injuries and genetic inheritance. These data also show that 4.6 % of the individuals between 18 and 44 years have hearing loss, while 14 % of middle aged individuals-between 45 and 64 years, and 54 % of the population above 65 years have some hearing loss. Moreover, it is known that metabolic changes, such as systemic arterial hypertension (SAH) is present in adults and may be empowered by the presence of hearing loss or vice versa.Īccording to data from the ASHA (American Speech-Language–Hearing Association), there are currently 28 million individuals in the USA with some type of hearing loss, and 80 % of those are irreversible cases. The hearing system affection may cause psychosocial effects, like low self-esteem, isolation, depression and irritability, which can interfere with the quality of life of the individuals. In the adult population, studies confirmed that hearing loss starts at about 30 years old, and increases progressively along the years, although there is a resemblance in the audiologic configuration, men are affected earlier and more intensely than women. The hearing loss (HL) is a factor that irrespectively of the degree of commitment affects the quality of life and when acquired in adults, it appears gradually and may make the oral language receiving difficult.
