Aim:
The aim of the study is the analysis of risk factors, influencing on the progression of chronic obstructive pulmonary disease.
Materials And Methods:
259 patients with chronic obstructive pulmonary disease (COPD) I and III stages, mean age 54,3±11,7 and the duration of the disease 10,1±5,7. Patients were divided into 2 groups: I group (n=119) - with III stage of disease, II group (n=140) - COPD with I stage. 30 healthy were involved in control group. The risk factors of progression of COPD were determined with the use of regressive and correlative analyses.
Results:
The level of markers of systemic inflammation in serum of patients with COPD: TNF-α (RR 3,25); IL-8 (RR 2,1); hs-CRP (RR 3,52) in combination with traditional risk factors (long course of the disease (RR 2,3), age (RR 1,65), smoking (RR 1,65), and also obesity (RR 2,45), early menopause (RR 3,52), hereditary respiratory predisposition (RR 3,05), and also coexisting cardiovascular pathology increase the risk of COPD progression several times. .
Conclusion:
According to the results of this trial, unmodified risk factors such as hereditary predisposition, early menopause, long course of the diseases and coexisting cardiovascular pathology contribute significantly on progression of COPD. The relative risk increases with increasing of concentration of markers of systemic inflammation (TNF-α, IL-8 and hs-CRP), that correlate with clinical manifestations of COPD: cough, shortness of breath on VAS in mm.

Chronic Obstructive Pulmonary Disease
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...

Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.
