目的了解门诊老年慢性阻塞性肺疾病(COPD)患者的肺功能和临床特点。方法回顾性分析卫生部北京医院2003—2008年78例老年COPD患者的肺功能检测指标及临床资料。结果FEV1%预计值为73.3±18.4,FEF50为36.77±19.93,两者呈正相关(r=0.8319P<0.0001)。年龄与肺功能各检测指标无相关性。各级COPD患者的高血压、冠心病、血糖代谢异常、血脂代谢异常、慢性肾脏病和脑血管病的发病率差异无统计学意义。二次复查肺功能有55.56%患者FEV1%下降,33.3%患者FEV1%上升。结论年龄不是影响老年COPD患者病程进展的单一因素。不能依靠单次肺功能检查评估患者的基础通气功能。应加强对老年COPD患者的宣教和随访。
Objective To understand the pulmonary function and clinical features of outpatients with chronic obstructive pulmonary disease (COPD). Methods Retrospective analysis of 78 cases of elderly COPD patients with pulmonary function tests and clinical data from 2003 to 2008 in Beijing Hospital of Ministry of Health. Results The predicted FEV1% was 73.3 ± 18.4 and the FEF50 was 36.77 ± 19.93, with a positive correlation (r = 0.8319P <0.0001). There was no correlation between age and pulmonary function test. The COPD patients at all levels of hypertension, coronary heart disease, abnormal glucose metabolism, abnormal lipid metabolism, chronic kidney disease and cerebrovascular disease incidence was not statistically significant. Secondary review of lung function in 55.56% of patients FEV1% decreased, 33.3% of patients FEV1% rise. Conclusion Age is not the single factor that affects the course of disease in older COPD patients. Patients can not be assessed for basal ventilatory function on a single lung function test. Missionary and follow-up of elderly patients with COPD should be strengthened.
