Background: Chronic Obstructive Pulmonary Disease (COPD) and Cardiovascular Diseases (CV) Often Coexist. COPD and CVD are complex diseases characterized by a strict interaction between environment and genetic. The mechanisms linking these two diseases are complex, multifactorial and not entirely understood, influencing the therapeutic approach. COPD is characterized by several comorbidities, it hypothesized the treatment of cardiovascular co-morbidities that may reduce morbidity and mortality. Flavonoids are an important class of plant low molecular weight Secondary Metabolites (SMs). Convincing data from laboratory, epidemiological, and human clinical studies point the important effects on CVD risk prevention. Objective: This review aims to provide up-to-date information on the ability of Flavonoids to reduce the CVD risk. Conclusion: Current studies support the potential of Flavonoids to prevent the risk of CVD. Well-designed clinical studies are suggested to evaluate advantages and limits of Flavonoids for managing CVD comorbidity in COPD.

Early stages of chronic obstructive pulmonary disease (COPD) are characterized by the loss and narrowing of terminal bronchioles in the lung, resulting in “air-trapping,” often occurring before overt emphysema manifests. Individuals with an airway-predominant phenotype of COPD display extensive lung air-trapping and are at greater cardiovascular disease (CVD) risk than COPD patients with an emphysema-predominant phenotype. We hypothesized that the degree of computed tomography (CT)-quantified lung air-trapping would be associated with greater aortic and carotid artery stiffness and lower endothelial function, known biomarkers of CVD risk. Lung air-trapping was associated with greater aortic stiffness (carotid femoral pulse wave velocity, CFPWV) ( r = 0.60, P = 0.007) and carotid β-stiffness ( r = 0.75, P = 0.0001) among adults with ( n = 10) and without ( n = 9) a clinical diagnosis of COPD and remained significant after adjusting for blood pressure (BP) and smoking history (pack-years) (carotid β-stiffness: r = 0.68, P < 0.01; CFPWV r = 0.53, P = 0.03). The association between lung air-trapping and carotid β-stiffness remained significant after additionally adjusting for age and forced expiratory volume 1(FEV1) ( r = 0.64, P = 0.01). In the COPD group only ( n = 10), lung air-trapping remained associated with carotid β-stiffness ( r = 0.82, P = 0.05) after adjustment for age, pack-years, and FEV1. In contrast, no association was observed between CFPWV and lung air-trapping after adjustment for BP, pack-years, age, and FEV1 ( r = 0.12, P = 0.83). Lung air-trapping was not associated with endothelial function (brachial artery flow-mediated dilation) in the entire cohort ( P = 0.80) or in patients with COPD only ( P = 0.71). These data suggest that carotid artery stiffness may be a mechanism explaining the link between airway-predominant phenotypes of COPD and high CVD risk. NEW & NOTEWORTHY Previous cross-sectional studies have demonstrated greater large elastic artery stiffness and lower endothelium-dependent dilation in chronic obstructive pulmonary disease (COPD) patients compared with controls. Furthermore, COPD patients with emphysema have greater aortic stiffness than non-COPD controls, and the degree of stiffness is associated with emphysema severity. The present study is the first to demonstrate that even before overt emphysema manifests, lung air-trapping is associated with carotid artery stiffness in COPD patients independent of blood pressure, age, or smoking history.

Aim. To determine plasma extracellular low-molecular-weight DNA (elmwDNA) as an indicator of apoptosis in patients with chronic obstructive pulmonary disease (COPD) in remission versus healthy donors, patients with chronic non-obstructive bronchitis (CNOB), and their first-degree relatives (FDRs). Subjects and methods. The investigation recruited 110 participants, including 17 healthy donors, 31 patients with COPD, and 20 patients with CNOB in remission, 19 healthy FDRs of patients with COPD, and 23 healthy FDRs of those with SNOB. The plasma levels of elmwDNA were determined in the study participants. Nucleic acids were isolated by phenol/chloroform extraction, precipitated with ethanol, and treated with RNase; elmwDNA was analyzed by electrophoresis. Results. In patients with COPD, the mean level of elmwDNA was 7.8±2.0 ng/ml, which was 3.9 and 3.0 times statistically significantly lower than that in healthy donors and patients with SNOB, respectively; while the level of elmwDNA in the latter did not differ statistically significantly from that in healthy donors. In both the blood relatives of patients with COPD and FDRs of those with SNOB, the mean level of elmwDNA was not significantly different from that in healthy donors. The content of elmwDNA tended to increase in COPD patients aged 60—80 years as compared to those aged 45—59 years; that in both age groups was, however, significantly lower than in healthy donors of the same age. Conclusion. The level of elmwDNA in plasma and, accordingly, apoptosis in the lung are reduced in patients with COPD in remission, whereas that is unchanged in those with SNOB. In patients with COPD, blood elmwDNA release is unrelated to heredity and varies little with age. The determination of elmwDNA is recommended for use in patients with COPD to assess apoptosis.

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.
