Abstract
BACKGROUND: Chronic obstructive pulmonary disease (COPD) is associated with a number of different comorbidities. Cardiovascular diseases (CVD) are the most frequent comorbidities in COPD. The economic burden associated with cardiovascular comorbidity (CVC) in this population of patients is considerable. The COPD patients are related to the increased systemic inflammation, reduced capacity for physical activity, and airflow obstruction.
AIM: The aim of our investigation was to evaluate the dyspnea as a disabling symptom in COPD patients with cardiovascular comorbidity (CVC) especially heart failure. The main aim of this study is to evaluate its intensity in patients with COPD in stages II according to GOLD.
METHODS: The investigation was conducted from December 2019 to January 2020, on pulmonology and allergology clinic and cardiology clinic of medical faculty in Skopje. We investigated 65 outpatients with COPD, 44 with different type of CVD, Group I, and 21 without CVD, Group II. All patients were with partial chronic respiratory failure (In type 1 respiratory failure hypoxemic). Patients, according GOLD initiative, were in COPD stadium II, 70% < forced expiratory volume in 1 s (FEV1)>50%. Heart condition was diagnosed on the basis of clinical examination, electrocardiography, and echocardiography of the heart. Included patients with CVD were with ejection fraction (EF) <65%. Dyspnea was measured with modified MRC (mMRC) dyspnea scale.
RESULTS: The forced vital capacity and forced expiratory volume in 1 s were statically significantly higher in Group II with CVD. Dyspnea measured with Modified Medical Research Council (MRC) dyspnea scale showed statistically significantly higher values in Group I COPD patients with CVC (2.9 ± 1.4) versus Group II without CVC (1.7 ± 1.4), (p < 0.05). The perception of the higher dyspnea in Group I was associated with increased COPD assessment test-scores, in Group I: Group I (19.8 ± 9.1) versus Group II: (9.8 ± 9.1), (p < 0.001). The number of exacerbations and what is more important the number of severe exacerbation leading to hospitalizations was statistically higher in patients of Group I with CVC than in Group II without CVC (3.0 ± 1.1 vs. 1.0 ± 2.1), (p < 0.001) and the number of hospitalizations (1.0 ± 1.1 vs. 0.3 ± 2.1) (p < 0.001).
CONCLUSION: We can conclude that patients with COPD who have CVC have an increased risk of high symptoms, which mean poor quality of life and increased morbidity.
