ABSTRACT

Introduction: PAD was asymptomatic in a large proportion of COPD patients and was associated with more severe lung disease than in COPD subjects without PAD.

Materials and Methods: This was a Cross-sectional study conducted at Department of Physiology, Santosh Medical College diagnosed with COPD using Spirometry was recruited for the study with a Sample size of 130 patients.

Results: The characteristics of the population for follow-up (n=130) are presented in table 1. The mean Mean±sd was 51.73±6.1 years. The prevalence of never smokers was 21.5%, former smokers were 51.5% and current smokers were 26.9%. In total, 41 out of 130 individuals (31.5%) had PAD based on an ABI of less than 0.6. A statistically significant association was found between COPD and newly diagnosed PAD during follow-up. The association between COPD and incident PAD was stronger (adjusted OR 1.91, 95% CI 1.14–3.21). Stratified analysis by smoking status revealed that the overall association between COPD and newly developed PAD was driven by the ever smoker group.

Conclusion: Subjects with COPD have a higher risk of developing PAD. People with both COPD and PAD have a substantially increased risk of death. Consequently, early detection of PAD and preventive actions in people with COPD should receive more attention in clinical respiratory care.
