老年及老年前期高血压和冠心病患者听力调查

Investigation of Hearing in Senile and Presenile Patients with Hypertension and Coronary Heart Disease

分析老年常见病──高血压、冠心病对听力的影响及老年人听力障碍的变化规律。对老年及老年前期高血压、冠心病患者103例与相应年龄健康人58例（对照组）进行听力检测和对比分析。结果：（1）患者组的听力减退发生率及平均听力损失均显著高于对照组（P＜0．01）;（2）各频率的平均纯音听阈均随年龄的增长而增加，越到高频区越明显；（3）老年及老年前期听力损失首先从4000Hz上频率开始，随着年龄的增长听力损失逐渐向中颇、低频区扩展，年龄越大全频区听力损失率越高。结论：生物性自然老化所致的听力损失比较轻，而高血区、冠心病则明显加速和加重了老年性聋的发生。

An analysis was made to find out the effects of common geriatric diseases- hy-pertension and coronary heart disease in the elderly on hearing and the regularity of hearing disorder. The hearing in 103 senile and presenile patients with hypertension and coronary heart diseasewas measured and analysed by comparison with 58 healthy people as control group with matchedages. The results showed that: (1) the incidence of hearing disorder and average hearing loss ateach audio frequency in patient group was much higher than that in control group (P <0. 01):(2) average pure tone threshold at each frequency increased with the growing age, especially athigh frequency: (3) senile and presenile hearing loss began with the frequency in more than4000 Hertz and gradually expanded to medium and low frequency range with the growing age,and the elder the people, the higher the hearing loss rate at full audio frequency range. It is concluded that natural aging may cause slight hearing loss, while hypertension and coronary heartdisease worsen the process of presbyacusis obviously.
