【摘要】 目的 探讨心脑血管病社区综合性干预对人群心电图的影响。评价干预效果。方法 1991～1992年,对北京郊区35～74岁农民1 833人做有关心脑血管病危险因素调查，三年干预后对2710人进行复查。采用WHO推荐使用的静息心电图明尼苏达编码方法，将两次心电图结果进行对比分析。结果 主要异常码和次要异常码的发生率在干预区由基线时的14.88%和31.28%，分别降至复查时的12.59%和30.76%；在对照区由基线时的9.97%和27.44%，分别升至复查时的11.51%和35.17%(P<0.001)。经过干预后，女性编码率的降低幅度大于男性，尤以4-.5-码为显著由12.2%和22.3%分别降至7.2%(P<0.01)和18.6%，而在对照区4-.5-码由基线时的5.8%和10.7%分别升至复查时的8.7%(P<0.05)和17.3%(P<0.001)。结论 心脑血管病人群干预是有效的，女性较男性显著。

     【Abstract 】 Objective To investigate theeffects of intervention on the ECG Minnesota coding in the population of Fangshan (one ofBeijing suburbs) farmers. Methods The investigationof cardio-and cerebrovascular disease risk factors were performed in 1 833 farmers withage 35-74 years in 1991-1992. After three-year intervention, 2 710 people were researchedagain. The WHO-recommended rest-ECG Minnesota coding rates were compared before and afterthree-year intervention in this study. Results Inthe intervention group, the major and minor abnormality codes were 14.88% and 31.28% atbaseline, and reduced to 12.59% and 30.76% after 3-year intervention respectively. In thecontrol group, the major and minor abnormality codes were increased from 9.97% and 27.44%at baseline to 11.51% and 35.17% after 3-year non-intervention respectively (P<0.001).After 3-year intervention, the abnormal code rate decreased more in female than in malewhich especially decreased in Minnesota 4-code (ST abnormalities) from 12.2% to 7.2%(P<0.01), and in 5-code (T wave changes) from 22.3% to 18.6%. In control group,abnormal code rate in 4-code increased from 5.8% to 8.7% (P<0.05) and in 5-code from10.7% to 17.3% (P<0.001). Conclusion Theseresults showed that community intervention has certain beneficial effects on cardio-andcerebrovascular disease demonstrated by ECG Minnesota coding rate, especially in femalewhich may be due to their good compliance during the intervention.
