Background: Chronic Obstructive Pulmonary Disease (COPD) which is characterized by persistent airflow restriction and respiratory symptoms. Studies demonstrated that cardiac arrhythmias, cardiovascular mortality and cardiac death increased in these patients due to altered myocardial repolarization. Frontal QRS-T angle is a novel marker of myocardial depolarization and repolarization heterogeneity. In this study, we aimed to investigate the relationship between frontal QRS-T angle and COPD severity in patients with newly diagnosed COPD. Methods: A total of 104 newly diagnosed COPD patients without any significant comorbidities were included in this study. Patients were divided into two groups according to GOLD stage as follows: patients with mild and moderate COPD (group I) and severe and very severe COPD (group II). Frontal QRS-T angle was calculated from the automatic report of the electrocardiography device . Results: Frontal QRS-T angle was significantly higher in group II patients compared to in group I patients (43.0 [25.5-60.0] vs. 20.0 [12.0-32.0], P < 0.001). The best cut-off value of frontal QRS-T angle for predicting severe-very severe COPD was ≥ 34.5°. Correlation analysis showed that frontal QRS-T angle was negatively correlated with FEV1/FVC (r = –0.524, P < 0.001) and MEF25-75 (r = –0.453, P < 0.001). In linear regression analysis, It was found that MEF25-75 (β: –0.593, P = 0.006) was the only independent predictor of the frontal QRS-T angle. Conclusions: Frontal QRS-T angle, an easily obtainable marker form surface electrocardiography. In this study, we have shown for the first time that frontal QRS-T angle was significantly increased in patients with severe and very severe COPD.

Abstract The aim of the study was to evaluate the effects of rehabilitation in patients with chronic obstructive pulmonary disease (COPD) using the Kinect system during stationary rehabilitation. The study included 68 patients with COPD (35 men, 33 women, mean age 61.3 ± 3.7). The subjects were randomly assigned to one of the two experimental groups described below. Group I included 34 patients – non‐participants in Kinect training. Group II included 34 patients – participants in Kinect training. In all patients before and after rehabilitation physical fitness was assessed using the Senior Fitness Test (SFT). The Xbox 360 and Kinect motion sensor were used to carry out virtual reality training. In group I, statistically significant improvements in SFT performance were observed. Patients in group II also showed statistically significant improvement in physical fitness in all attempts of the SFT. Virtual rehabilitation training in patients with COPD seems to be a practical and beneficial intervention capable of enhancing mobility and physical fitness.

Aim. To study the specific clinical features in patients with coronary heart disease, CHD (stable effort angina, SEA) and chronic obstructive pulmonary disease (COPD), in order to improve early diagnostics of this combined pathology. Material and methods. The study was a retrospective analysis of 958 medical histories. Co-existing COPD was registered in 251 patients (26,3 %). Therefore, Group I included 251 patients with SEA and COPD (26,3 %), while Group II included 707 SEA patients without COPD (73,7 %). Results. In Group I, there were more men than women, by 5,7 % (р<0,05). No significant differences in age and angina functional class were observed between Groups I and II. In patients with SEA and COPD, the prevalence of arterial hypertension and myocardial infarction was higher than in Group II (р<0,05). In addition, Group I was characterised by higher prevalence of dyspnoea, palpitation, C-reactive protein elevation, and lipid metabolism disturbances. Conclusion. Among chronic CHD patients hospitalized to the cardiology unit, co-existing COPD was registered in 26,3 %. The combination with COPD aggravated the clinical course of CHD. The study results support the use of lung function assessment in smoking CHD patients, to diagnose co-existing COPD.

The prevalence of chronic Chlamydia pneumoniae infection was assessed in 54 patients with established chronic obstructive pulmonary disease (COPD), 41 of these with severe COPD (group I), 13 with mild to moderate COPD (group II), and in 23 patients with community-acquired pneumonia (controls, group III). Specific IgG and IgA antibody levels and circulating immune complexes (ICs) were measured in paired sera, and specific secretory IgA (sIgA) levels in sputum specimens. A polymerase chain reaction (PCR) test was used for the detection of C. pneumoniae in sputum. According to our definite diagnosis criterion, 65% of the COPD patients showed evidence of suspected chronic C. pneumoniae infection and the prevalence was still higher (71%) in patients with severe disease. The occurrence of specific markers of infection was invariably highest in patients with severe COPD, next-highest in patients with mild to moderate COPD and lowest in pneumonia patients. The association between COPD and C. pneumoniae infection persisted after controlling for the potential confounding factors.

Background: There is total alteration of various antioxidants in response to the oxidative stress, which is one of the major patho-physiologic hallmarks in chronic obstructive pulmonary disease (COPD) development. This study aims to establish the correlation between different antioxidants in normals and COPD, study the alteration in the correlation due to COPD and smoking as well as the impact of COPD and smoking on antioxidants levels.Methods: Study comprises of 96 normals as group I and 96 COPD patients as group II. The antioxidants albumin (Alb), bilirubin (Bil), uric acid (UA) ceruloplasmin (Cp), glutathione peroxidase (GSHPx), catalase (CAT) and superoxide dismutase 3 (SOD3) were estimated.Results: Significant lower serum Alb, UA, SOD3 and increased serum Cp and GSHPx were found in Group II. Significant correlation was found between Alb and UA (r=0.24); Bil and UA (r=0.26); Alb and CAT (r=0.211) and SOD3 and CAT (r=0.318) in normals. However, these correlations were altered in COPD where Alb correlates with Bil (r=0.235); UA with CAT (r=0.203) and SOD3 with GSHPx (r=-0.27). The correlation between SOD3 and CAT remained unaltered. Similar correlation of UA with Alb and Bil was observed in nonsmoker normals and between SOD3 and CAT in smoker normals. In COPD, no correlation was seen in nonsmokers, while in smokers Alb correlates with Bil (r=0.316) and SOD3 with CAT (r=0.317).Conclusions: These alterations may have clinical ramifications in further understanding the pathogenesis of COPD and developing therapeutic approaches.

Aim. To study the specifics of coronary artery pathology in patients with coronary heart disease (CHD) and chronic obstructive pulmonary disease (COPD), using the data of selective coronary angiography (CAG). Material and methods. In total, 907 CHD patients were examined. Group I included 251 participants with CHD and COPD; Group II included 656 individuals with CHD only. CAG was performed in 582 patients (64,2%): 184 from Group I (73,3%) and 398 from Group II (60,7%). Results. In patients with the combination of cardiac and pulmonary disease, the prevalence of two- and three-vessel pathology was higher, compared to CHD-only patients: 70,6% in Group I vs. 53,8% in Group II (p=0,002). In Group I, the Syntax Scale score was significantly higher than in Group II (24,7±4,1 vs. 18,7±3,1, respectively). Conclusion. Patients with combined cardiac and pulmonary pathology demonstrated a more severe coronary artery atherosclerosis, based on such CAG parameters as stenosis degree, number of involved vessels, size and location of lesions, and proximal stenosis.

Oxidative stress is a driving factor in the pathophysiology of chronic obstructive pulmonary disease (COPD). While paraoxonase 1 (PON1) is an antioxidant enzyme and a potential biomarker of this disease, data regarding the status of PON-1 in COPD are inconclusive. In this regard, to shed light on this issue, we performed a meta-analysis of data on PON1 activity in COPD. Electronic databases (MEDLINE, Embase and CENTRAL) were searched for available studies on PON1 activity in patients with stable COPD published before October 2021. A meta-analysis was performed using random-effects models. Twelve studies (12 studies on paraoxonase and three on arylesterase) were identified. Patients with COPD had lower levels of paraoxonase activity (standard mean difference [SMD] −0.77, 95% confidence interval [CI] −1.35 to −0.18) and arylesterase activity (SMD −1.15, 95% CI −1.95 to −0.36) in comparison to healthy controls. In subgroup analyses, paraoxonase activity was lower in patients of studies as consisted of mainly non-severe COPD (SMD −1.42, 95% CI −2.04 to −0.79) and, by contrast, slightly higher in patients of studies including severe COPD (SMD 0.33, 95% CI 0.02 to 0.64) in comparison to healthy controls. Arylesterase activity showed a similar trend. Overall, PON1 activity was lower in patients with COPD, suggesting that PON1-related antioxidant defense is impaired in COPD. Future studies are warranted.

Abstract Background The conjunction of chronic obstructive pulmonary disease (COPD) and obstructive sleep apnea (OSA) is known as overlap syndrome (OS). The coexistence of these diseases has cardiovascular morbidity and mortality. The aim of this study is to assess the prevalence of OSA in COPD patients. One hundred COPD patients (obese and non-obese) performed sleep questionnaires and polysomnograms. Results OSA prevalence in COPD was 50% and it increases with increasing disease severity (P < 0.001). The highest prevalence of OSA was found in obese patients with severe COPD; 90.5% of these patients have OSA. In the OSA group, obese patients were found to have significantly higher STOP-Bang Questionnaire (SBQ), Epworth Sleep Scale (ESS), modified medical research council (mMRC) dyspnea scale, apnea-hypopnea index (AHI), respiratory disturbance index (RDI), and oxygen desaturation index (ODI). Both obese and non-obese COPD patients showed significant positive correlations between AHI and smoking index (SI), SBQ, ESS, mMRC, ODI, and neck circumference (NC). Conclusions From this study, it can be concluded that moderate and severe COPD patients had a higher diagnosis of sleep-disordered breathing. Also, obese-COPD patients are more susceptible to develop OSA.
