Abstract

Objective: The purpose of this study is to compare pulmonary function test (PFT) and exercise capacity between non-anemia and anemia COPD patients.

Materials and Methods: A total of 80 participants with COPD were enrolled and divided into non-anemic and anemic COPD. Pulmonary function test was assessed using standard spirometry to measure forced vital capacity (FVC), forced expiratory volume in one second (FEV₁), and the FEV₁/FVC ratio. Exercise capacity was evaluated using the six-minute walk test (6MWT), with the six-minute walk distance (6MWD) recorded and adjusted for each participant.

Results: The results shown FVC and the %predicted FVC were statistically significant differences between anemic and non-anemic COPD. The FEV1, % predicted FEV1, and FEV1/FVC were no statistically significant differences between anemic and non-anemic COPD. Additionally, 6MWD was significantly lower in anemic COPD compared to non-anemia COPD (p < 0.05), suggesting that anemia is associated with reduced exercise capacity in COPD patients.

Conclusions: Anemic COPD patients had significantly lower FVC, %predicted FVC, and 6MWD (p < 0.05), indicating impaired pulmonary function and exercise capacity. Hemoglobin level may be a useful parameter for assessing rehabilitation readiness and guiding treatment decisions in this group.
