Filter by:Pulmonary hypertension is a common complication of chronic obstructive pulmonary disease (COPD). It is reported that over half of COPD patients develop pulmonary hypertension. COPD and pulmonary hypertension may have pathological or genetics interactions so that patients having both disorders tend to have poor prognosis. Echocardiography is widely used to detect pulmonary hypertension, but it's not accurate enough. Therefore, high-quality data reflecting the prevalence, disease course and outcome of pulmonary hypertension in COPD is very limited in China. The aim of the study is to detect pulmonary hypertension with right heart catheterization, describe its outcome in Chinese COPD patients and explore the underlying interaction mechanism.
Chronic obstructive pulmonary disease (COPD) is closely related to venous thromboembolism (VTE). But it is difficult to identify VTE in COPD patients in clinical practice. Therefore, the prevalence data of PTE in COPD is limited. Pulmonary thromboembolism (PTE) is an important factor effecting patients outcomes, but existing researches only have short follow-up time less than 1 year. This study aim to develop an early detection system of PTE in COPD and explore the disease course and prognosis.
Over half of chronic obstructive pulmonary disease (COPD) patients develop pulmonary hypertension. The current therapy focuses only on the basic disease and there are a lot of controversies about the use of PAH target therapy in group 3 pulmonary hypertension. Our study is to explore whether sildenafil, a pulmonary arterial hypertension (PAH) target drug, could be efficient and safe in improving symptoms and survival of severe pulmonary hypertension caused by COPD.
The pulmonary vasculopathy and right heart dysfunction in COPD are drawing increasing attention these days. Recent researches show that pulmonary vasculopathy and right heart dysfunction relate to greater severity in COPD. Applying appropriate modalities for early detection of pulmonary vasculopathy and right heart dysfunction is of great importance. What's more, the interaction mechanism between pulmonary vasculature, right heart and COPD still needs to be further studied. The aim of our study is to develop an assessment system of pulmonary vasculopathy and right heart dysfunction in COPD patients and elucidate their impact on COPD course and outcome.
Chronic obstructive pulmonary diseases (COPD) coexisting with obstructive sleep apnea is called overlap syndrome (OS). Patients with OS seem to have worse prognosis than patients with only one disorder. Noninvasive positive pressure ventilation is an efficient treatment in obstructive sleep apnea, but the effectiveness in improving outcomes of OS patients is still not fully investigated. The aim of this non-randomized concurrent control trial is to evaluate noninvasive positive pressure ventilation's effectiveness in OS patients.
The goal of the research project PROTECT is to translate the Person-Centred Care (PCC) principles into an eHealth (the use of information and communication technologies for health) context. A developed PCC eHealth platform will be used as a tool to identify patients´ resources to enhance coping and living with their chronic illness by means of a dialog and partnership with staff and relatives. The PCC eHealth platform will not replace, but instead be used as add on treatment to usual care (guideline directed care).
COPD and sleep apnea dyspnea syndrome represent two of the most common chronic lung diseases. It is reported that the prevalence of COPD with sleep apnea dyspnea syndrome is also very high. COPD and sleep apnea may have pathological or genetics interactions so that patients having both disorders tend to have worse outcomes than either condition alone. Data reflecting the prevalence, disease course and outcome of overlap syndrome is very limited in China. Therefore, the aim of the study is to describe the prevalence, treatment and outcome in Chinese patients and exploring the underlying interaction mechanism.
ASTUTE is a pragmatic open randomised 12-week multinational trial to evaluate the effectiveness of aclidinium bromide/formoterol fumarate dihydrate fixed-dose combination compared to standard of care bronchodilators in chronic obstructive pulmonary disease.
To Assess the Utility of Impulse Oscillometry on a Differential Diagnosis among the Patients with ACOS,asthma and COPD over Age 40.
Chronic obstructive pulmonary disease (COPD) and asthma are frequent and disabling pathologies. The general practitioner is often at the front line vis-a-vis screening, diagnosis and treatment of these pathologies. There are currently many treatments available, in particular inhaled corticosteroids, and although the recommendations for management appear to be well codified in theory, the adaptation of drug therapy remains complex in general practice. The prescription of inhaled corticosteroids, often initiated during a general medicine consultation, is not simple. The aim of this study is to analyze the relevance of the prescription of inhaled corticosteroids in primary care and to identify the criteria necessary for the prescription of inhaled corticosteroids available in general practice. The main objective of our study is to evaluate the rate of consultations where all the elements required for guiding the prescription of an inhaled corticoid are available. The secondary objectives are: - Identify other factors associated with decision-making - Identify the causes of inhaled corticosteroid stopping (de-prescription)
