The Level of Cholesterol in COPD Patients with Severe and Very Severe Stage of the Disease

BACKGROUND: High blood cholesterol is part of metabolic syndrome and can be caused by medical conditions or bad dietary habits. AIM: The aim of the study was to investigate the prevalence of hypercholesterolemia in privies diagnosed patients with the severe and very severe stage of COPD, which were stable. MATERIAL AND METHODS: We investigated 100 subjects, all of them smokers, with smoking status >10 years, stratified into two groups: with severe and very severe stage of the disease. It was clinical, randomized, cross-sectional study. Besides demographic parameters and functional parameters, body mass index, cholesterol, LDL, and HDL were investigated. RESULTS: In the group of patients with very severe COPD were recorded significantly higher average values of cholesterol (6.16 ± 1.5 vs. 5.61 ± 1.1, p = 0.039). As independent significant factors influencing cholesterol in the group with a very severe COPD were confirmed the age of the patients (p = 0.005), LDL (p = 0.004) and HDL (p = 0.002). In the group with severe COPD, only LDL was confirmed as an independent significant factor that has an impact on cholesterol (p < 0.0001). CONCLUSION: The results of our survey demonstrated a high level of blood cholesterol and LDL, and low level of blood HDL in both investigated group’s patients with COPD.
