Objective To explore the significance of early screening on chronic obstructive pulmonary disease (COPD) with 6 min walk test. Methods Forty cases of COPD patients in sta bled stage with long - time smoking history or the symptoms of chronic cough and expectoration were selected from Jan. 2006 to Feb. 2009 in our hospital. Twenty cases of COPD in grade I (light) were selected as COPD I group and 20 cases of COPD in grade II (moderate) were selected as COPD II group. Another 20 cases of healthy volunteers were selected as control group. The 6 MWT and lung function of the three groups were detected and compared. Results The levels of FEV1 and 6 - MWT of COPD I and II group were obviously lower than those of the control group. The 6~MWT of COPD II group was obviously lower than that of COPD I group. Con clusion 6 - MWT can reflect the lung function of patients. It is simple, convenient, and appropri ate for community clinic or grass - root medical unit to screen on the patients with long - time smok ing history or the symptoms of chronic cough and expectoration, so as to make the patients receive further lung function detection and standard treatment in professional medical institutions.%目的 探讨6 min步行试验(6- MWT)对慢性阻塞性肺疾病(COPD)高危人群的早期筛查意义.方法 选择2006年1月～2009年2月在本院呼吸内科就诊的稳定期COPD患者40例,均有长期吸烟史或慢性咳嗽、咳痰症状,其中COPDⅠ级(轻度)患者20例作为COPDⅠ组,Ⅱ级(中度)患者20例作为COPDⅡ组,另选择健康志愿者20例作为对照组.3组均进行6-MWT及肺功能检查,记录并对结果进行比较.结果 COPDⅠ组、Ⅱ组FEV1及6-MWT距离均显著小于对照组,差异有统计学意义.COPDⅡ组6-MWT距离显著小于COPDⅠ组,差异有统计学意义.结论6min步行试验可以较好地反映患者的肺功能,并且简便易行,适合在社区诊所或基层医疗单位对长期吸烟或有慢性咳嗽、咳痰症状者进行筛查,以便进一步在专业医疗机构进行肺功能检查和规范治疗.
