甘肃省酒泉地区25488名2～17岁人群心脏杂音检出率与先天性心脏病发病率调查

A SURVEY ON HEART MURMUR INSPECT RATE AND CONGENITAL HEART DISEASE PREVALENCE RATE OF 25488 STUDENTS AGED 2～17 IN JIUQUAN DISTRICT

目的 对甘肃省酒泉地区 2 5 4 88名 2～ 17岁人群心脏杂音及先天性心脏病 (CHD)的发病率进行流行病学调查。方法 采用心脏听诊、测量身高、体重等方法做初步筛选 ,对心脏杂音阳性者进一步行拍胸部X线片、心电图、超声心动图等检查以确诊。根据不同年龄、性别、城乡不同进行数据处理。结果 心脏杂音检出率为 6 .0 4‰ ;CHD发病率为 3.81‰ ;年龄越小 ,CHD发病率越高 ,2～ 6岁与 7～ 17岁二年龄段之间比较差异有统计学意义 (P <0 .0 1) ;杂音检出率及CHD发病率城市与农村之间、男女之间比较差异无统计学意义 (P >0 .0 5 )。CHD以室内间隔缺损 (VSD)为多见。结论 心脏杂音高低与CHD多少呈明显正相关 ,流行病学调查是发现CHD的一个重要途径。

Objective TO examine the prevalence rate of heart murmur and congenital heart disease(CHD)in west area of Jiuquan. Methods Cardiac auscultation was performed to detect the positive of heart murmur,and UCG ECG or X-ray was used to clear the diagnosis.All the students examined weight and height.The data were controlled according to the difference of age,sex and area of urban and rural. Results Positive rate of heart murmur was 6.04‰ and prevalence rate of CHD was 3.81 ‰.The prevalence of CHD was decreasing with age and it had significant difference between groups of 2～6 years old and 7～17 year (P<0.01).Compared area and sex,there was no difference(P>0.05 ). Conclusion Prevalence rate of CHD is closely associated with positive rate of heart murmur.Epidemiological survey is an important way to diagnosis the disease.
