高血压对老年人听力影响的观察

Influence of Hypertension on Hearing Threshold in the Elderly

  • 摘要: 目的观察高血压对老年人听力的影响。方法采用ModsenOB40型电子纯音听力计测定66例老年高血压患者及正常老年人40人纯音听阈。高血压组作动态血压(ABPM)检查,并根据血压昼夜节律异常及听力损伤与否,分组作组间比较。结果发现老年人听力有不同程度减退。与健康组比较,高血压组在0.25~2kHz时差异明显(P<0.05)。在4~8kHz时更明显(P<0.01)。高血压患者中昼夜节律异常组听力更减退,差异明显(P<0.05);听力损伤组24hSBP、SBP负荷较高,差异明显(P<0.05)。结论高血压是老年人听力损伤的病因之一,高血压血压昼夜节律异常与24hSBP、SBP负荷高者老年人听力损伤更严重。降压治疗,控制24hSBP与SBP负荷及恢复昼夜节律应有利于减缓老年人听力的衰退

     

    Abstract: Aim\ To study the relation of the presbyacusis to the hypertension.\ Methods\ The hearing thresholds of 66 hypertensive men and women aged 60 ̄79 years were compared with those of 40 healthly men and women aged 62 ̄72 years.\ Hypertensive group was evaluated by circadian variation with ambulatory pressure monitoring(ABPM) and divided into dipper and nondipper group.\ Results\ The hearing threshlod rose with increase of age.\ 025 ̄8 kHz mean puretone threshlods of the hypertensive rose more markedly than the healthy(P<005 and 001).\ The occurrences of hearing loss in nondipper group was much more greater than in dipper group(P<005).\ 24h SBP and SBP load in hearing loss group rose more markedly(P<005).\ Conclusion\ Hypertension apparently affect on hearing lose in elderly.
