我国风湿性心脏病的流行现状

An updated epidemiologic status of rheumatic heart disease in China ——A survey report on rheumatic heart disease for the National Eighth Five year Key Project of rheumatic fever investigation

目的 掌握我国风湿性心脏病的近期流行状况。方法 １９９３￣１９９５年对我国东、南、西、北、中六个省、市协作区的５￣１８岁学生样本人群进行风湿性心脏病调查。结果 据１９９４年调查资料，在２６９５４６人中共发现风湿性心脏病５９例，总患病率为０．２２％。各地患病率从０．０３‰至０．４０‰；农村患病率高于城市；患病率随年龄而增长，而男、女间无明显差异。病例中单纯二尖瓣病变占７３．７％。

Objective To study the current status of rheumatic heart disease(RHD) in China.Methods Annual screening survey was performed among student population samples aged 5 18 in six provinces or cities located geographically in the eastern, southern, western, northern and central regions across China from 1993 to 1995. Results Fifty nine RHD patients were found among 269 546 students surveyed in 1994. The prevalence rate was 0.22 per 1000, ranging from 0.03 to 0.40 per 1000 in different regions. The prevalence was higher in the rural than in the urban areas and increased with age; male and female made no remarkable difference. Among the RHD cases, pure mitral valve lesions accounted for 73.7% and pure mitral stenosis 9.2%; 23.7% of the cases were found to have rheumatic activity during the survey. Conclusion The results reveal that RHD prevalence among Chinese children and adolescents has decreased remarkably during the past two decades but it is still high in some regions. A long term monitoring of the epidemiologic trend and community control of RHD is necessary to be continued.
