目的探讨VRI在COPD中的临床价值。方法选择新疆医科大学一附院呼吸科行VRI及肺功能检查的100例住院慢阻肺患者与35例健康志愿者,分析VRI与肺功能的相关性。结果慢阻肺患者VRI结果与对照组相比存在显著差异(P<0.01),振动曲线异常和动态图像异常随病情严重程度而改变(P<0.05),且与FEV1%pred呈相关(复合相关系数r=0.549,P<0.01)。结论 VRI对COPD诊断及评价病情严重程度有重要临床价值。
Objective To investigate the clinical value of VRI in COPD. Methods 100 hospitalized patients with chronic obstructive pulmonary disease and 35 healthy volunteers who underwent VRI and pulmonary function tests in Respiratory Department of First Affiliated Hospital of Xinjiang Medical University were selected to analyze the correlation between VRI and pulmonary function. Results There was significant difference in VRI between COPD group and control group (P <0.01), abnormal vibration curve and dynamic image abnormality with the severity of illness (P <0.05), and were correlated with FEV1% pred Coefficient r = 0.549, P <0.01). Conclusion VRI has important clinical value in diagnosing and evaluating the severity of COPD.
