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.
