These patients were noted to be younger (59 versus 61 years, p < 0.001) and less likely to have insulin-dependent diabetes (3.0 versus 4.4%, p < 0.001), preoperative dyspnea (2.2 versus 6.0%, p < 0.001), COPD (3.0 versus 4.2%, p = 0.011), and hypertension (40.7 versus 46.9%, p < 0.001) than patients who stayed longer.
In recent years, multiorgan clinical ultrasonography (pulmonary, cardiac and vascular) has emerged as a tool of considerable usefulness in managing patients with COPD in numerous situations, including the differential diagnosis of dyspnoea of uncertain origin, the assessment of the aetiology in episodes of exacerbation, detecting concomitant heart failure or associated pulmonary hypertension and as support in managing cardiovascular risk factors such as subclinical atherosclerosis.
The following associations emerged among respiratory symptom/disease cumulative incidence and risk factor exposure changes: a two-to-five fold higher risk for COPD, phlegm, cough, dyspnoea, asthma attacks, airway obstruction in persistent smokers; a two-to-three fold higher risk for COPD in remittent smokers; a two-fold higher risk for AR, phlegm and a four-fold higher risk for asthma in subjects with persistent occupational exposure; a two-fold higher risk for cough, phlegm, dyspnoea, AR in subjects with incident occupational exposure; a two-fold higher risk for AR, asthma attacks, COPD in subjects with incident traffic exposure.
VitaBreath is a portable, non-invasive ventilation device (pNIV) that relieves shortness of breath in COPD by delivering fixed inspiratory and expiratory positive airway pressures (IPAP/EPAP: 18/8 cmH<sub>2</sub>O).
Other significant improvements with IND/MF (QMF 149) vs Sal/Flu were noted for dyspnea at week 12 and other COPD symptoms and COPD rescue medication use over the 12 weeks.
The BODE score (incorporating body mass index, airflow obstruction, dyspnea and exercise capacity) is used for the timing of listing for lung transplantation (LTx) in COPD, based on survival data from the original BODE cohort.
One hundred and thirty-three patients with COPD were assessed at baseline by spirometry, pulse oximetry (SpO<sub>2</sub>), body composition, intensity of dyspnea, distance walked in the 6-minute walk test (6MWT), and Charlson Comorbidity Index (CCI).
Comparison between COPD Assessment Test (CAT) and modified Medical Research Council (mMRC) dyspnea scores for evaluation of clinical symptoms, comorbidities and medical resources utilization in COPD patients.
Accordingly, DB is often underdiagnosed or misdiagnosed, given the similarity of its associated symptoms (dyspnea, tachycardia, and dizziness) to those of other common cardiopulmonary diseases such as COPD and asthma.
The tolerability of the device for subjects with COPD appeared to be only slightly hampered by an increased sense of dyspnea attributed to wearing a mask.
We aimed to investigate whether subjects with COPD showing significant resting tidal F-V enveloping (ie, > 50% tidal volume) would present with higher exertional operating lung volumes, which would lead to greater burden of dyspnea and poorer exercise tolerance compared to their counterparts.
Improvements in St George's Respiratory Questionnaire and transition dyspnea index were significantly greater than placebo in both current and ex-smokers, whereas changes in COPD assessment test were significant only among current smokers.
The prevalence of COPD is high among smokers and ex-smokers with one or more respiratory symptoms seen in primary care, and the presence of wheeze, phlegm and dyspnea, together with both low BMI and obesity identify a subgroup with an even higher likelihood of COPD.
Pulmonary rehabilitation (PR) improves exercise capacity, health-related quality of life (HRQoL) and dyspnoea in patients with COPD and other lung conditions.
The Portuguese version of the MDP is the first valid and reliable instrument to assess dyspnea multidimensionally in Portuguese-speaking patients with COPD.
We analyzed the association of dyspnea severity, quality of life status, and lung function with lung function measurements and exacerbation risk in 982 patients enrolled in the Korea COPD Subgroup Registry and Subtype Research study.
Here, we review the physiological and psychological consequences of activity-related dyspnea in COPD, assess the efficacy of modern management strategies in improving this common respiratory symptom, and discuss key unmet clinical and research needs that warrant further immediate attention.
However, older women remained more likely to experience severe dyspnea and to manifest more severe COPD (B vs A) than older men, despite lower pack-years of smoking.
Patients were classified according to COPD severity (1) in GOLD 2016 "ABCD" categories based on symptoms (Medical Research Council dyspnea grade, COPD Assessment Test, breathlessness), percent predicted FEV1, and exacerbation history and (2) as mild, moderate, severe, or very severe based on treatment and exacerbation history.
The aim of our study was to evaluate the relationship between the degree of dyspnea and exercise capacity in subjects with COPD who had the same severity of air-flow obstruction.
