Background: Six minute walk test (6MWT), represent a useful marker for exercise capacity and dynamic hyperination of COPD patients.Highresolution
computed tomography (HRCT) has allowed in detection of airway wall abnormalities and emphysema, whose extent may correlate with
the clinical severity of the disease in COPD patients.
Material & methods: A cross sectional study was carried in 100 COPD patients attending Department of Respiratory Medicine, Institute of
respiratory diseases, SMS Medical College, Jaipur, during June 2018 to May 2019.All patients underwent clinically (Modied Medical Research
Council), radiologically (HRCT) &6MWT.
Results: The 6MWT showed that a negative correlation to dyspnea (mMRC grading), emphysema score & post FEV1% predicted (p<0.0001).
Conclusion: The HRCT emphysema score can be used as an initial parameter for identify patients with high risk for COPD.
