Filter by:Background: In patients with chronic obstructive pulmonary disease (COPD) and concomitant cardiovascular conditions cardio-selective beta-blockers reduce mortality and can be used without significant negative effects on lung function or respiratory symptoms. Observational studies indicate that beta-blocker therapy in COPD even without overt cardiovascular disease, is associated with reduced risk for mortality and COPD exacerbations. Aim: The overall purpose of our study is to examine the benefit of general beta-blocker therapy on important patient-oriented measures in chronic obstructive pulmonary disease (COPD). Our primary hypothesis that treatment with beta-blockers in patients with COPD and no comorbid heart disease at baseline can prevent a Composite measure of hospitalizations due to cardiovascular diseases, COPD exacerbations and death. Population: 1700 patients with C OPD. Inclusion criteria are FEV1/FVC < 70, age >40 years and sinus rhythm 50-120/min. Exclusion criteria include hypersensitivity against metoprolol, atrioventricular (AV) block II or II or sick sinus syndrome without pacemaker, atrial fibrillation or flutter, clinical signs of or previously known cardiovascular disease, systolic blood pressure < 90, severe asthma, present beta-blocker therapy or ongoing COPD exacerbation. Intervention: Metoprolol at a target dose of 100 mg in addition to standard COPD care. Control: No placebo control. Randomized, pragmatic un-blinded controlled study where the control Group receives standard COPD care. Outcome: The primary outcome is a composite measure of all-cause mortality, C OPD exacerbations, and cardiovascular events after one year. Endpoint data from Swedish national registries and clinical follow-up. Importance: Beta-blocker treatment to attenuate morbidity in patients with COPD could have great clinical and social importance at a low cost.
Chronic obstructive pulmonary disease (COPD) is characterised by non-reversible bronchial obstruction associated with systemic disorders and comorbid factors. Dynamic hyperinflation during an exercise increase dyspnea and can reduce exercise capacity. Stair climbing is associated with prolonged dynamic hyperinflation and severe dyspnea in COPD patients. The aim of this study is to carry out the effect of an energy conservation technique on dyspnea to facilitate stair climbing.
The trial aims to analyse changes in the microbiome of the lower airways after smoking cessation. Microbiome analyses (upper airway swabs, bronchoalveolar lavage, transbronchial brushing) are conducted in smokers before and 6 weeks after smoking cessation. Never smokers serve as a control group and undergo the same sampling procedures once.
This clinical investigation will evaluate the patient-equipment interface and patient preference in the use of modern possibilities for remote monitoring of patients with COPD in a personalized care approach.
Chronic obstructive pulmonary disease (COPD) is a chronic respiratory disease characterized by persistent respiratory symptoms and airflow limitation. Pervasive dynamic pulmonary hyperinflation (DPH) and intrinsic positive end-expiratory pressure (PEEPi) can increase inspiratory threshold load and respiratory effort, leading to abnormal changes in respiratory mechanics and neural respiratory drive (NRD). Non-invasive positive pressure ventilation (NPPV) is not only widely used in respiratory failure, but also is one of the important lung rehabilitation strategies. Several studies have reported that the use of biphasic positive airway pressure (BIPAP) mode for NPPV can improve ventilation, reduce NRD, improve NRD coupling, significantly reduce inspiratory muscle load and relieve symptoms. However, relatively few studies are reported that the NPPV is used in COPD patients without non-respiratory failure. Therefore, we suppose that for stable COPD patients without respiratory failure, early intervention with NPPV may reduce DPH, eliminate the adverse effects of PEEPi, reduce the respiratory muscle load, improve the respiratory physiological characteristics, and delay the progression of the disease. Therefore, the purpose of this study is to observe the influence of different levels of BIPAP ventilation on respiratory mechanics and NRD in patients with stable COPD, and to explore whether BiPAP ventilation can be used as a pulmonary rehabilitation method for early intervention of COPD and provide a theoretical basis for subsequent clinical trials.
Ventilated by a single-limb tubing with PEV caused CO2 rebreathing to COPD patients during exercise with the increasing ventilation. The aim of this study was to evaluate whether CO2 rebreathing could be avoided with the use of the dual-limb circuit, to provide a theoretical basis of more rational clinical application of NIV in the setting of increasing ventilation(eg, after exercise).
Early pulmonary rehabilitation is recommended after an episode of severe exacerbation of chronic obstructive pulmonary disease (COPD). However, its implementation is challenging particularly as regard exercise training. Several studies showed that transcutaneous electrical nerve stimulation (TENS) could improve dyspnea and pulmonary function. The aim of this study is to assess the acute effect of TENS on exercise tolerance in post-exacerbation COPD patients
The purpose of the project is to investigate changes in the quadriceps muscle and cardiovascular regulation during exercise in relation to improved lung function after lung transplantation in patients with COPD.
Primary Objective: To investigate effects of SAR440340 (anti-interleukin-33 [IL-33] monoclonal antibody [mAb]) compared with placebo, on the annualized rate of moderate-to-severe acute exacerbations of COPD (AECOPD) over up to 52 weeks of treatment. - Moderate exacerbations were recorded by the Investigator and defined as AECOPD that require either systemic corticosteroids (such as intramuscular, intravenous or oral) and/or antibiotics. - Severe exacerbations were recorded by the Investigator and defined as AECOPD requiring hospitalization, emergency medical care visit or resulting in death. Secondary Objectives: To investigate effects of SAR440340 compared with placebo, on improving respiratory function, as assessed by pre-bronchodilator forced exploratory volume in 1 second (FEV1). To evaluate effects of SAR440340 compared with placebo, on post-bronchodilator FEV1. To evaluate effects of SAR440340 compared with placebo, on duration from baseline to first moderate or severe AECOPD event. To evaluate effects of SAR440340 compared with placebo, on safety and tolerability.
This trial will evaluate the effect of acetazolamide (375 mg per day) vs. placebo on lung water content by ultrasound at acute altitude exposure in patients with Chronic Obstructive Pulmonary Disease (COPD).
