introduction: arterial gas derangement could change urinary sodium excretion in chronic obstructive pulmonary disease (copd) patients.there are very few and conflicting data in regards to the measurement of fractional excretion of sodium in copd patients. the main aim of this study was to assess the relationship between renal fractional excretion of sodium(fena) with arterial blood gas and spir...

the clinical copd questionnaire (ccq) has been developed to measure the health status of copd patients. the aim of this study was to translate ccq into the persian language and assess the validity and reliability of the translated version. we used a forward-backward procedure to translate the questionnaire. in a cross-sectional study 100 copd patients and 50 healthy subjects over 40 years old w...

abstract background: chronic obstructive pulmonary disease (copd) is currently the fourth cause of mortality worldwide. patients with copd experience periods of dyspnea, fatigue, and disability, which impact on their life. the objective of this study was to investigate the effect of short‑term inspiratory muscle training on exercise capacity, exertional dyspnea, and pulmonary lung function. mat...

background: resistive inspiratory muscle training (rimt) is a well-known technique for rehabilitation of patients with chronic obstructive pulmonary disease (copd). incentive spirometry is another technique with potential viability for this application, but there is limited evidence in support of its efficacy in the rehabilitation of copd patients. aim: the objective of this study was to compar...

Natriuretic peptides (NPs) are a family of prognostic biomarkers in patients with heart failure (HF). HF is one of the most frequent comorbidities in patients with chronic obstructive pulmonary disease (COPD). However, the prognostic role of NP in COPD patients remains unclear. The aim of this meta-analysis was to evaluate the relation between NP and all-cause mortality in COPD patients. We per...

Mild-to-moderate pulmonary hypertension is a common complication of chronic obstructive pulmonary disease (COPD); such a complication is associated with increased risks of exacerbation and decreased survival. Pulmonary hypertension usually worsens during exercise, sleep and exacerbation. Pulmonary vascular remodelling in COPD is the main cause of increase in pulmonary artery pressure and is tho...

1. C-type natriuretic peptide is a neuropeptide, which is also produced by the vascular endothelial cells. Plasma immunoreactive C-type natriuretic peptide concentrations in patients with various diseases have not yet been studied. 2. Plasma immunoreactive C-type natriuretic peptide concentrations were studied by radioimmunoassay in normal subjects, patients with congestive heart failure, non-d...

introduction: chronic obstructive pulmonary disease (copd) patients are at increased risk of sleep-disorders. the concomitant occurrence of copd and obstructive sleep apnea hypopnea syndrome (osahs) is named overlap syndrome. this study aimed to evaluate the severity of osahs in overlap syndrome patients.materials & methods: this cross-sectional study was conducted on adult patients with forced...
