Background: For chronic obstructive pulmonary disease, spirometry assessment of post-bronchodilator FEV1 is critical for establishing the diagnosis, staging the disease, predicting the outcome, and planning treatment. The six-minute walk test (6MWT) is an endurance test used to evaluate the functional status of patients with cardiopulmonary disorders. CAT score is a well-established tool for determining the impact of COPD on one's health.
Objective: To determine the correlation between spirometric indices FEV1, FVC, FEV1/FVC, 6MWT and CAT Scores in COPD patients.
Design: Cross-sectional study
Setting: Conducted from September 2019 to September 2021 for a period of 24 months in a tertiary care hospital in India
Materials and Methods: In this study, the correlation between spirometric indices FEV1, FVC, FEV1/FVC, 6MWT and CAT Scores were analyzed in 100 patients diagnosed with COPD.
Main outcome measures: 6MWT, CAT Scores and Spirometry values in COPD
Sample size: 100
Results: Most patients were males(75%) between 61-70(36%). Most were in Stage 3 COPD(55%), followed by stage 2 of GOLD staging(25%). Most of them had a CAT score range of 21–30(51%), followed by 10–20(48%), and on 6MWT majority walked a distance of 301-400 meters(43%), followed by > 400 meters(35%). The pulse rate and mean systolic blood pressure increased while mean SpO2 decreased post-6WMT with a statistically significant difference(P
