Purpose: The aim of our study was to determine whether the RS time measured on an electrocardiogram is associated with severity chronic obstructive pulmonary disease (COPD).
 Materials and Methods: population made up 100 COPD patients a mean age 63 ± 10 years (86% were males). These divided into mild moderate (GOLD 1–2) group (n = 45) severe very 3–4) 55) according Global Initiative for Ch...

Chronic obstructive pulmonary disease (COPD) is chronic that affects mostly the lungs but there growing evidence it also a systemic condition associated with number of accompanying diseases known as comorbidities. inflammation and oxidative stress are highlight pathogenic processes interrelate COPD comorbidities additional specific risk factors mechanisms. Through complex interactions increases...

Evidence has been accumulating that chronic inactivity leading to muscle disuse is unlikely to be the only explanation for the peripheral muscle dysfunction of chronic obstructive pulmonary disease (COPD) patients. Although a new concept of myopathy was recently proposed, the question of disuse and/or a form of myopathy is still being debated. This review proposes definitions for the terms used...

Introduction: Pulmonary hyperinflation in patients with chronic obstructive pulmonary disease (COPD) can increase the breathing rate and reduce diaphragmatic movements by pushing the diaphragms downward and limiting their movements; this, in fact, can affect the breathing process. The purpose of this study was to compare diaphragmatic movements in COPD patients and healthy ones and to evaluate ...

background: vitamin d has a potential to modulate inflammatory response against noxious particles in patients with chronic obstructive pulmonary disease (copd). the present study was conducted to determine the status of serum vitamin d in copd versus healthy group. methods: the patients presented to the outpatient pulmonary clinic of ayatollah rouhani hospital, babol iran. diagnosis of copd was...

Pulmonary strongyloidiasis is an uncommon presentation of Strongyloides infection, usually seen in immunocompromised hosts. The manifestations are similar to that of acute exacerbation of chronic obstructive pulmonary disease (COPD). Therefore, the diagnosis of pulmonary strongyloidiasis could be challenging in a COPD patient, unless a high index of suspicion is maintained. Here, we present a c...

8-Isoprostane is a potential in vivo marker for oxidant burden, but its usefulness in induced sputum of smokers and chronic obstructive pulmonary disease (COPD) has not been investigated. The current study investigated 58 subjects comprising 11 never-smokers, 11 ex-smokers, 13 healthy current smokers and 23 COPD with stage 0-III disease (according to the Global Initiative for Chronic Obstructiv...

pulmonary hypertension (ph) is an important cause of heart failure in chronic obstructive pulmonary disease (copd). the pro brain natriuretic peptide n-terminal (nt-probnp) has been suggested as a noninvasive marker to evaluate ventricular function. however, there is no evidence to support the use of nt-probnp in monitoring the benefits of vasodilators in copd induced ph. thus, we used nt-probn...

background: several studies have showed an increased prevalence of airflow obstruction in first degree relatives of individuals with chronic obstructive pulmonary disease (copd). considering no specific research had evaluated airway resistance in offspring of patients with severe copd, we utilized a spirometry and a impulse oscillometry (io) to evaluate this population. materials and methods: i...
