北京农民高血压患者干预前后静息心电图明尼苏达编码对比分析

Comparison of the restECG Minnesota codings between preand postintervention in the population of farmers in a Beijing suburb Fangshan

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１８３３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。

Objective To investigate the effects of intervention on the ECG Minnesota coding in the population of Fangshan (one of Beijing suburbs) farmers. Methods The investigation of cardioand cerebrovascular disease risk factors were performed in 1 833 farmers with age 3574 years in 19911992. After threeyear intervention, 2 710 people were researched again. The WHOrecommended restECG Minnesota coding rates were compared before and after threeyear intervention in this study. Results In the intervention group, the major and minor abnormality codes were 14.88% and 31.28% at baseline, and reduced to 12.59% and 30.76% after 3year intervention respectively. In the control 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 male which 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 from 10.7% to 17.3% (P<0.001). Conclusion These results showed that community intervention has certain beneficial effects on cardioand cerebrovascular disease demonstrated by ECG Minnesota coding rate, especially in female which may be due to their good compliance during the intervention.
