Filter by:Heart failure is a progressive disease that decreases the pumping action of the heart. This may cause a backup of fluid in the heart and may result in heart beat changes. Using very low electrical pulses that travel across the inside of the chest cavity, thoracic fluid status monitoring (OptiVol™) can measure the level of resistance to the electrical pulses, which indicates the level of fluid in the chest. The purpose of this study is to collect information related to fluid build up in the chest of subjects with heart failure.
The proposed study intends to evaluate the impact of the NT-proBNP assay on the diagnosis of heart failure in patients with dyspnea of unknown etiology presenting to the emergency room and admitted to the medical wards.
The BEACON trial (Best Practices for End-of-Life Care for Our Nations' Veterans) was a six-site implementation study to evaluate a multi-component, education-based intervention to improve the quality of end-of-life care provided in VA Medical Centers.
SHORTIE is a two-phase study to determine the impact of the Triage Profiler S.O.B. (Shortness Of Breath) Panel on patient management, outcome, and cost.
The objectives of this study are to: - Evaluate the sensitivity and specificity of NT-proBNP (N-terminal prohormone brain natriuretic peptide) and new biomarker measurements for the diagnosis of heart failure in patients with acute dyspnea and/or edema. - Determine the exact biomarker cut-off point(s) for the differentiation of healthy persons, patients with heart failure and patients with dyspnea of other origin. - Evaluate treatment costs in patients with dyspnea under special consideration of NT-proBNP measurement.
More and more general practitioners (GPs) use spirometry in their practices. At this time, there is sufficient reason to presume that, after a single postgraduate training program without any further support, most GPs have insufficient knowledge and ability to assure valid interpretation of their spirometry tests. Therefore, some kind of continuous diagnostic support with regard to spirometry interpretation by GPs is advisable. The aim of the present study is to assess whether implementation of spirometry expert support (either by a computerised expert system or a working agreement between general practitioners and respiratory consultants with respect to spirometry interpretation) causes changes in diagnosing and appropriateness and efficiency of medical care in subjects with chronic respiratory morbidity managed in general practice.
Cost-effective management of heart failure and pulmonary disease is of paramount importance. Unfortunately, the rapid and accurate differentiation of heart failure from other causes of dyspnea in private practice is challenging. B-type natriuretic peptide (BNP) levels are significantly higher in patients with congestive heart failure as compared to patients with dyspnea due to other causes. As a simple, non-expensive assay easily applicable in private practice is available, rapid measurement of BNP might be very helpful in establishing or excluding the diagnosis of heart failure in patients presenting with acute dyspnea in private practice. The aim is to test the hypothesis that a BNP guided diagnostic strategy would improve the evaluation and management of patients presenting with acute dyspnea to physicians in private practice and thereby reduce total cost of diagnosis and treatment. The primary endpoint is total medical cost within 3 months.
The purpose of this study is to determine whether acupuncture is effective in relieving shortness of breath among breast and lung cancer patients.
RATIONALE: Buspirone may be effective in reducing dyspnea (shortness of breath) in patients with cancer who are undergoing chemotherapy. PURPOSE: Randomized clinical trial to study the effectiveness of buspirone in reducing shortness of breath in patients who are undergoing chemotherapy for cancer.
The purpose of this study is to test the hypothesis that treatment with oral ALT-711 twice daily for 16 weeks will improve aortic distensibility, exercise tolerance, and quality of life in elderly patients with isolated diastolic heart failure (DHF), and that the improvements in exercise tolerance will correlate with the improvements in aortic distensibility.
