Background: The aim of this study was to evaluate atrial electromechanical delay (AEMD) with both electrocardiography (ECG) and echocardiography in patients with Chronic Obstructive Pulmonary Disease (COPD). Methods: Total of 110 patients were included in this cross-sectional case-control study. P-wave dispersion (PWD) was measured on a 12-lead ECG. Atrial electromechanical intervals (PA) were measured as the time interval between the onset of the P wave on the ECG and the beginning of the late diastolic A wave. Results: PWD was found to be 40.9±9.2 ms in the healthy control group, 45.6±8.2 ms in the mild COPD and 44.8±8.7 ms in the severe COPD group (p<0.05). Intra-right atrial EMD was found to be 10.7±5.8 ms in mild COPD, 11.0±7 ms in severe COPD, and it was 16.4±7.3 ms in healthy control group (p<0.001). Interatrial EMD was detected to be 29.5±9.1 ms in the control group, 24.1±9 ms in mild COPD group, and 23.9±11.1 ms in the severe COPD group (p<0.001). Conclusion: Both mild and severe COPD groups decreased PWD, increased tricuspid PA and significantly decreased inter- and right intra-AEMD times in comparison to the control group.

Introduction: Cardiovascular complications caused by chronic obstructive pulmonary disease (COPD) will change the normal function and the shape of the heart’s anatomy. The purpose of this study to determine whether there was a relationship between the degree of severity of COPD and electrocardiogram (ECG) changes. Methods: A cross-sectional analysis conduct on 80 subjects who fulfilled inclusion criteria at the outpatient cardiology clinic H. Adam Malik Hospital Medan. The subject was divided equally based on the severity of COPD and ECG examination was performed. Statistical analysis processed using multivariate with p>0,05 as statistical significance The correlation is presented as Pearson r values and new values are obtained by the ROC curve. Results: The mean age was 57±13 years with males have a majority proportion (85%). P Pulmonale and RBBB were common in severe COPD (GOLD 3 p = 0.001, GOLD 4 p <0.001). P wave axis and the amplitude of the P wave was found to be significantly different (p <0.001) with a strong and moderate correlation (r = 0.706 and r = 0.577). P-axis values of more than 56.3 degrees and P-wave amplitudes of more than 0.15 mV had a sensitivity of 80-85% and specificity of 80% to differentiate more severe COPD. Conclusion: ECG assessment can be used to differentiate severe COPD with a fairly good correlation. ECG assessment in COPD patients can be used as the initial modality for assessing severe COPD (GOLD 3 and GOLD 4) at H. Adam Malik Hospital Medan.

Introduction The oral cavity and pharynx have a rich sensory system composed of specialized receptors. The integrity of oropharyngeal sensation is thought to be fundamental for safe and efficient swallowing. Chronic obstructive pulmonary disease (COPD) patients are at risk for oropharyngeal sensory impairment due to frequent use of inhaled medications and comorbidities including gastroesophageal reflux disease. Objective This study aimed to describe and compare oral and oropharyngeal sensory function measured using noninstrumental clinical methods in adults with COPD and healthy controls. Method Participants included 27 adults (18 men, nine women) with a diagnosis of COPD and a mean age of 66.56 years ( SD = 8.68). The control group comprised 11 healthy adults (five men, six women) with a mean age of 60.09 years ( SD = 11.57). Spirometry measures confirmed reduced functional expiratory volumes (% predicted) in the COPD patients compared to the control participants. All participants completed a case history interview and underwent clinical evaluation of oral and oropharyngeal sensation by a speech-language pathologist. The sensory evaluation explored the detection of tactile and temperature stimuli delivered by cotton swab to six locations in the oral cavity and two in the oropharynx as well as identification of the taste of stimuli administered in 5-ml boluses to the mouth. Analyses explored the frequencies of accurate responses regarding stimulus location, temperature and taste between groups, and between age groups (“≤ 65 years” and “> 65 years”) within the COPD cohort. Results We found significantly higher frequencies of reported use of inhaled medications ( p < .001) and xerostomia ( p = .003) in the COPD cohort. Oral cavity thermal sensation ( p = .009) was reduced in the COPD participants, and a significant age-related decline in gustatory sensation was found in the COPD group ( p = .018). Conclusion This study found that most of the measures of oral and oropharyngeal sensation remained intact in the COPD group. Oral thermal sensation was impaired in individuals with COPD, and reduced gustatory sensation was observed in the older COPD participants. Possible links between these results and the use of inhaled medication by individuals with COPD are discussed.

The aim: To evaluate P-wave dispersion (PwD), as an independent predictor of atrial fibrillation, corrected QT interval dispersion (cQTD), the noninvasive marker of ventricular arrhythmia and sudden cardiac death, investigate the atrial electromechanical delay in patients with COPD and assess their relation with the severity of the disease. Materials and methods: We prospectively enrolled consecutive patients with newly diagnosed COPD (n = 53, age 41.2 ± 6.8 years), compared with an age-matched healthy control group (n = 51, age 40.9 ± 6.5 years). A standard 12-lead electrocardiogram of each patient was analyzed for PwD and сQTD. Atrial electromechanical delay was analyzed by echocardiographic tissue Doppler imaging. The difference between PAs-PAl, PAs-PAt, and PAl-PAt were defined as left intra-atrial, right intra-atrial, and interatrial electromechanical delays (EMD), respectively. Results: PwD was higher in COPD patients than in control subjects (39.47 ± 3.12 ms vs. 30.29 ± 3.17 ms, p < 0.05). In comparison between control group and COPD subgroups (mild, moderate and severe), there was a statistically significant difference among these free groups in terms of PwD. Subgroup analyses showed that this difference was mainly due to patients with severe COPD. Regarding cQTD, there was a statistically significant increase in COPD patients 57.92 ± 3.43 ms vs 41.03 ± 5.21 ms, p < 0.05 respectively. PAs, PAl and PAt durations, right intra-atrial and interatrial EMD were also significantly longer in COPD patients (p < 0.05). Furthermore, there were significant negative correlations between FEV1 and PwD (r = – 0.46, p < 0.05), right intra-atrial (r = – 0.39 ms, p < 0.05), interatrial EMD ( r = – 0.35 ms, p < 0.05) and cQTD (r = – 0.32, p < 0.05). Conclusions: Atrial conduction time, such as inter- and intra-atrial EMD intervals, PwD and cQTD were longer than in healthy controls and correlated with the severity of COPD. These parameters offer a non-invasive and cost-effective assessment method for detecting patients at high risk of arrhythmia. Nevertheless, further prospective investigations on this issue are required.

Background: Chronic Obstructive Pulmonary Disease (COPD) leads to limited activity and reduced quality of life. Treatment of this disease is a long-term process that requires the cooperation of patients in monitoring and treatment. Methods: In the present study which was conducted from April 2019 to March 2021 in Masih Daneshvari Hospital, Tehran, Iran, 75 patients were randomly divided into telerehabilitation and control groups. Patients in the control group received pulmonary rehabilitation including respiratory, isometric, and aerobic exercises for 8 weeks, three times per week. In the second group, patients were given a lung rehabilitation booklet and asked to repeat the exercises three times a week for four weeks according to a specific schedule. In addition, patients installed Behzee care application on the mobile phone that recorded various indicators such as heart rate, SpO2, dyspnea, fatigue, and daily activities. This application reminded the patient of the program every day and at a specific time. Finally, the patients’ conditions were compared in the two groups after 8 weeks using CAT and mMRC questionnaires and 6-Minute Walk (6MW) exercise indices as well as spirometry tests. Results: In all four indicators (6MW, CAT,  and mMRC questionnaires as well as spirometry), patients showed improvement after rehabilitation (p<0.001). This improvement was significantly higher in the telemedicine group compared to the other group (p<0.01). Conclusion: The use of telerehabilitation in COPD patients is effective in improving spirometry indices, quality of life, as well as activity and sports indices.

Introduction: Chronic obstructive pulmonary disease (COPD) is the leading cause of morbidity and mortality worldwide. Cigarette smoke and noxious agent result in oxidative stress and activate release of inflammatory mediators such as Interleukin-8 (IL-8). Quercetin is a flavonoid compound containing anti-inflammatory effects which can be used as an adjuvant therapy in stable COPD. Objective: To analyze the effect of quercetin on serum IL-8 levels, % VEP1, and CAT score of stable COPD patients. Methods: Experimental clinical trial with pre-test and pasca-test design was performed in 30 patients with stable COPD in Dr. Moewardi Surakarta between December 2017 and January 2018. The samples taken by using purposive sampling were divided into two groups treatment groups received standard therapy and quercetin 500mg/day for 28 days and control groups only received standard therapy. The decrease in inflammation was measured by serum IL-8 examination, improvement of obstruction measured by %FEV1 and clinical improvement measured by CAT score. Results: IL-8 serum level was significantly lower in treatment group than of in control group (p=0,001). The percentage of FEV1 was insignificant different between the two group (p=0,236). However CAT score was significantly lower in treatment group compared to that of in control group (p=0,001) Conclusions: Quercetin can decrease IL-8 serum level and decrease CAT score when given in combination with standard therapy for COPD patients.

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.

Abstract Background Chronic mucus hypersecretion is a common feature in chronic obstructive pulmonary disease (COPD) and is associated with epidermal growth factor (EGF) activity. Aberrant EGF and its receptor signalling can cause airway hyperproliferation, increase in mucous cell differentiation and mucus hyperproduction. Furthermore, it can also promote subepithelial fibrosis and excessive collagen deposition in COPD. The objective of this research was to investigate the plasma levels of EGF in smokers with COPD in comparison with clinically healthy smokers. In addition, the relationship between the plasma levels of EGF and clinical features was investigated. Methods A cross-sectional study included 82 clinically stable male patients with mild-to-very severe COPD (mean age: 64.5±8.6 years), and the control group consisted of 86 healthy male smokers (mean age: 61.6±9.5 years). To define COPD, we performed spirometry and classified COPD using Global Initiative for Chronic Obstructive Lung Disease (GOLD) classification. We analyzed the levels of EGF by enzyme-linked immunosorbent assay in plasma. Results The mean serum levels of EGF were significantly lower in smokers with COPD than those in controls (69.30 and 83.82 pg/mL, respectively, p = 0.046). The plasma levels of EGF were significantly different (p = 0.004) between mild COPD and moderate-to-very severe COPD. There were no significant differences between the levels of EGF in plasma of spontaneous sputum producers (COPD patients) vs. nonsputum producers (p = 0.101) and between nonexacerbated COPD and exacerbated COPD patients(p = 0.138). Conclusions There is a significant difference in the plasma levels of EGF in male smokers with COPD as compared with male healthy smokers. Our findings suggest that the plasma levels of EGF may contribute to the pathogenesis of COPD.
