Filter by:The purpose of this study is to determine if Coreg CR is as effective as Coreg IR in improving heart function in subjects with stable chronic heart failure.
The purpose of this study is to determine if sildenafil (Viagra) improves exercise tolerance.
Despite advances in medical therapy for patients with heart failure, one-third of patients remain limited by fatigue and shortness of breath. Our previous study concluded that one dose of sildenafil (Viagra) lead to an improvement in heart pressure and exercise capacity. Currently sildenafil is not FDA approved for the treatment of heart failure. The purpose of this study is to determine if treatment with sildenafil for 12 weeks in patients with heart failure can improve exercise capacity and quality of life in people with heart failure.
The primary purpose of this study is to determine the effectiveness of telemonitoring compared with usual guideline-based care in preventing hospitalization for heart failure patients.
The purpose of this study is to determine if the hemodialysis procedure changes the risk for cardiac arrest in patients.
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.
Primary: - To assess the efficacy of SR121463B in correcting hyponatremia in patients with dilutional hyponatremia other than SIADH or cirrhosis Secondary: - To assess the long-term efficacy of SR121463B in maintaining normonatremia in these patients - To assess the safety and tolerability of SR121463B
The purpose of this study is to test the ability of a new X-ray technique called CT angiography to identify significant narrowing of the coronary arteries compared to traditional coronary angiogram.
The purpose of the study is to determine the effectiveness of a home-delivered variant of the chronic disease self management program in improving health outcomes in patients with chronic conditions.
Telehomecare is a technology that individuals use in their homes to communicate with health providers electronically. This technology can help them function at a higher level and avoid undesirable hospitalizations by making changes in their everyday behaviors, but research is needed to understand how telehomecare supports health behavior change and leads to improved health status. The hypothesis being tested is that the use of an electronic method of monitoring and transmitting health information facilitates patient empowerment, with subsequent effects on the patient's ability to manage her/his treatment regimen more effectively. The study will explore the relationship between telehomecare and acquisition of knowledge, and will show whether changes in knowledge levels translate to changes in behaviors and improved health outcomes. The effects of two different telehomecare systems (nurse-directed vs. patient-directed) on knowledge, self-management, and health status will be compared. A further goal is to illuminate the attitudes of physicians regarding the use of telehomecare in the treatment of their elderly, community dwelling patients. Results will inform managers and policymakers who are responsible for integrating eHealth mechanisms into chronic disease protocols, funding health care programs, and creating policies that support the use of information technology by all Americans.
