比较135例突聋病人与135例耳部正常人和111例确诊为冠心病病人,尽可能按年龄、性别和发病时间分组。观察项目为冠心病危险因素:血清总胆固醇、低密度脂蛋白(LDL)、高密度脂蛋白(HDL)、甘油三酸脂、血压、体重、糖尿病、吸烟嗜好和阳性家族史。发病率。1964年以来Koln大学HNO临床医院收治住院的突聋病人的发病率除个别年份外,从60年代至80年代末逐年增加,至目前为止达到最高峰。性别分布,在135例突聋病人和所配对的对照组中,女∶男为1∶1.1,年龄11～81岁(48.4±16.2岁)。突聋组中,男女间HDL随机抽样t检验有显著差异,对照组中,
135 cases of sudden deafness and 135 cases of normal ears and 111 cases of patients diagnosed as coronary heart disease were compared. Patients were grouped by age, sex and time of onset. The observation items were coronary risk factors: serum total cholesterol, low density lipoprotein (LDL), high density lipoprotein (HDL), triglyceride, blood pressure, body weight, diabetes, smoking habits and positive family history. Incidence. Since 1964, the incidence of sudden deaf patients hospitalized at HNO Clinic in Koln University has increased year by year from the 1960s to the late 1980s and reached its peak so far, except for a few years. Gender distribution Among 135 patients with sudden deafness and matched controls, the female: male was 1: 1.1, and the age was 11 to 81 years old (48.4 ± 16.2 years). Sudden deaf group, male and female HDL random sampling t test were significantly different in the control group,
