Filter by:The purpose of the VENT Cost-Effectiveness Sub-Study is to gather healthcare utilization and quality of life information on patients enrolled in the VENT study in order to analyze the relative cost-effectiveness of the endobronchial valve implant procedure.
The purpose of this study is to assess the safety and efficacy of the Emphasys Endobronchial Valve (EBV) and procedure (with pulmonary rehabilitation) compared to optimal medical management (with pulmonary rehabilitation) in patients with heterogeneous emphysema.
The purpose of this study was to compare the effect of exercise treatment combined with breathing retraining (a computerized feedback program), with exercise treatment combined with heliox (a helium and oxygen combination), with exercise only in patients with moderate to severe chronic obstructive pulmonary disease. This was an 8-week intervention study.
The purpose of this study is to determine whether the Aeris Bronchoscopic Lung Volume Reduction (BLVR) System is safe in patients with advanced emphysema.
The purpose of this study is to evaluate the safety and effectiveness of yoga in reducing shortness of breath in people with chronic obstructive pulmonary disease (COPD). Patients in this study must have moderate to severe COPD and be primarily limited by shortness of breath.
The main objectives of this study are to see if a type of lung surgery, known as lung reduction surgery, in addition to standard medical treatment improves the quality of life, lung function, and reduces the high mortality associated with severe emphysema when compared to standard medical treatment alone. Another goal of this study is to better identify the patients most likely to benefit from this surgical treatment. The information obtained in this study is important because lung reduction surgery is being done in several centers around the country but its long term benefits, if any, over standard medical treatment, are not known.
To conduct feasibility studies on the use of retinoids in the treatment of emphysema. Specific objectives are to identify optimal patient populations, retinoids, doses, dosing schedules, routes of administration, and outcome measures preparatory to conducting a larger, controlled, clinical trial on the efficacy of retinoid therapy in the management of emphysema.
To evaluate the long term efficacy, morbidity and mortality associated with medical therapy with lung volume reduction surgery (LVRS) as compared to medical therapy alone and to define patient selection criteria. The trial, conducted in conjunction with a patient registry, is supported by the NHLBI, the Centers for Medicare and Medicaid Services (CMS), and the Agency for Healthcare Research and Quality (AHRQ).
To determine if enteral nutrition support (ENS) restores normal body weight and improves muscle strength, exercise performance, sensation of dyspnea, and quality of life in malnourished patients with chronic obstructive pulmonary disease.
