2,239 Clinical Trials for Various Conditions
The primary objective of this study is to evaluate the feasibility of a novel app to facilitate heart failure patients to acquire lung ultrasound images and evaluate the quality of those images to expert scans, and to evaluate for relationships between the ultrasound data and pulmonary pressure data from the Abbott CardioMEMS system.
The purpose of this clinical trial is to see if a new device (SCD) is safe and if it can reduce damage to the kidney enough to allow medications to work to improve heart and kidney function for use in patients that have moderate to severe heart failure and is at least in part due to heart failure and it not responding to standard medical therapy. The SCD is a cartridge used with a commercial hemodialysis unit. Participants will be enrolled in the clinical trial once eligibility is confirmed. In addition to clinical assessments and laboratory testing participants will have surface echocardiograms during the trial. The SCD treatment will take place for 4 hours on day 1, 3, and 5 while on hemodialysis.
The goal of this study is to determine if sleep disordered breathing results in a measurable degree of overnight myocardial stress/injury in patients with acutely decompensated congestive heart failure. A secondary goal is to determine of a period of medical management attenuates this sleep disordered breathing-induced cardiac injury in this patient population.
Congestive heart disease (CHF) can frequently cause transudative pleural effusions, some of which do not completely resolve with diuretics alone. These effusions can cause significant morbidity, leading to ongoing dyspnea and hypoxia, resulting in additional office and hospital visits. TREAT-CHF is a randomized trial studying tunneled pleural catheter (TPC) versus standard medical management for the treatment recurrent symptomatic pleural effusions secondary to CHF that are refractory to maximal medical therapy. TREAT-CHF will study whether the addition of a TPC can improve quality of life and minimize health care utilization over the one year following insertion.
This study will assess the ability of a novel optical measurement system to determine changes in the hemodynamic status of heart failure patients admitted to the hospital with a primary diagnosis of acute decompensated heart failure. Patients will be measured with both the novel measurement system and reference devices that are FDA-cleared for hemodynamic measurements. The measurements from the novel system will be compared to reference variables describing hemodynamic and congestive status, including stroke volume, central venous pressure, and serum levels of NT-proBNP.
The purpose of this study was to investigate the effects of initiation of sacubitril/valsartan vs enalapril treatment on objective measures of both waking activity and sleep in subjects with heart failure with reduced ejection fraction.
To evaluate the safety and to determine the efficacy of D-ribose for the treatment of congestive heart failure (CHF) in subjects who have been stabilized following hospitalization with acute decompensation.
Premature ventricular contractions (PVC) are a very common irregular heart beat (arrhythmias) even in patients without heart disease. Frequent PVCs are thought to occur in about 1-4% of the general population. Many patients with PVCs complain about skipping of their heart (palpitations), shortness of breath and feeling tired. In some patients PVCs may also result in weakening of the heart muscle (heart failure), which might be reversible with suppression of the PVCs.
Historically, transthoracic Doppler echocardiography has been unable to provide interpretable data of blood flow within the lung parenchyma because of air attenuation of Doppler signals. Recently, a transthoracic Doppler system known as the Sonara/tek Transcranial Doppler (TCD) System has been developed that can identify parenchymal pulmonary blood flow (PPBF) signals. The ability to non-invasively collect information regarding the pulmonary aspect of the cardio-pulmonary system may provide valuable information and new insights into the structural and functional characteristics of the lung parenchyma and vasculature in health and disease states.
This is a randomized controlled trial of a CPR video decision aid in patients with advanced congestive heart failure (CHF).
The purpose of this project is to conduct a preliminary test of the feasibility of a multi-micronutrient intervention to improve micronutrient status, cardiac function and quality of life in Veterans with Congestive Heart Failure (CHF).

The objective of this investigation is to evaluate the safety and effectiveness of the OPTIMIZER® System in subjects with medically refractory moderate-to-severe heart failure.
This is a prospective, double blinded randomized clinical study to evaluate the Effects of Pentoxifylline on left ventricular systolic function indices and circulating biomarkers in patients with chronic congestive heart failure. A few studies all focused in Africa have consistently shown marked beneficial effects of pentoxifylline in improvement of left ventricular size and systolic function along with marked decrease in biomarkers of heart failure and apoptosis markers on top of standard CHF therapy. Furthermore pentoxifylline was shown to have negligible effects on heart rate, blood pressure in those studies. Limitations of these studies are that they are largely single center originating in the African subcontinent and have never been tested in the North American population, particularly Caucasians. Despite major advances in medical therapy for congestive heart failure, it is still one of the leading causes of morbidity and mortality in North America. Most medications tested for improvement of Ejection Fraction with the exception of Beta-Blockers and Ace-Inhibitors have been associated with worsening mortality. Pentoxifylline is a medication that has negligible effects on myocardial oxygen consumption, yet promising effects on inflammatory markers seen in CHF with the possibility of improvement in LV systolic function and symptomology and may prove to be a useful addition for CHF patients. This would prove to be especially useful, particularly when associated with no major side effects.
Early morning weights to monitor CHF patient's fluid status is common practice but there is a lack of evidence that this is the best practice. The purpose of this study is to determine if there is a difference in net weight gain or loss for hospitalized patients with CHF who are weighed in the evening instead of early morning.
This study evaluated the effect of early initiation of aliskiren therapy, compared to standard therapy, in the reduction of cardiovascular death and heart failure re-hospitalization events within 6 months, in congestive heart failure (CHF) patients hospitalized for an episode of acute decompensated heart failure.
PP1- The purpose of this study is to determine whether giving more of the hormone produced by everyone called growth hormone releasing hormone (GHRH) can improve heart function in individuals with congestive heart failure. You must be 50 years old or older, have a diagnosis of congestive heart failure, and have a high likelihood of having lower than normal growth hormone effect. GHRH is approved by the US FDA for treatment in children with growth hormone deficiency because GHRH stimulates Growth Hormone (GH). Its use for treatment of congestive heart failure in adults is investigational. Growth hormone releasing hormone is a hormone produced in the brain. We will be using synthetic hormone made in the laboratory. It is identical to the hormone in the brain. Many older people, due to aging have low levels of growth hormone. The aim of this study is to find out whether restoring growth hormone levels to the levels found in younger individuals and then maintaining those levels for 12 weeks will help strengthen heard muscles in older persons with congestive heart failure.
The Patient-Reported Outcomes Measurement Information System (PROMIS) is an NIH Roadmap initiative to develop a computerized system measuring patient-reported outcomes in respondents with a wide range of chronic diseases and demographic characteristics. In the first four years of its existence, the PROMIS network developed item banks for measuring patient-reported outcomes in the areas of pain, fatigue, emotional distress, physical function, and social functioning. During the item banking process, the PROMIS network conducted focus groups, individual cognitive interviews, and lexile (reading level) analyses to refine the meaning, clarity, and literacy demands of all items. The item banks were administered to over 20,000 respondents and calibrated using models based on item response theory (IRT). Using these IRT calibrations, computerized adaptive test (CAT) algorithms were developed and implemented. The network has designed a series of studies using clinical populations to evaluate the item attributes, examine their utility as CATs, and validate the item banks. More information on the PROMIS network can be found at www.nihpromis.org. The purpose of this research study is to learn about the experience and impact of having congestive heart failure (CHF). In particular, we hope to develop better questionnaires that can measure heart failure patients' quality-of-life.
OSA is associated with large negative swings in the intrathoracic pressure, significant increase in the sympathetic nerve activity and repetitive surges in blood pressure, along with episodic hypoxia and hypercapnea (8,9). These autonomic and respiratory changes may increase the cardiac muscle workload, cardiac dysrrhythmia, and exacerbate ischemia (10,11,12). Treatment with CPAP is the most successful therapeutic modality available for OSA. It is still not clear whether establishing the diagnosis of OSA and initiating treatment with CPAP while still in the hospital carries any benefit in the management of patients with acute heart failure. This study will evaluate the effect of work up and treatment of OSA on the outcome of patients hospitalized with acute CHF.
This study will evaluate whether treating sleep apnea while in the hospital would help heart failure, and assist recovery from the worsening of the heart function more than the current clinical standard of waiting for treatment until the subject have left the hospital. Heart failure affects more than 2% of the US population and is the only cardiovascular disorder with rising incidence. The annual cost of CHF in 2005 was $ 27.9 billion, large percentage of which is the cost of hospitalizations for exacerbation of CHF. Half of patients with CHF have some form of sleep apnea, and most of them go undiagnosed. Patients with CHF and OSA benefit from treatment with CPAP as an outpatient. The society can benefit from developing recommendations for approaching sleep apnea in the hospitalized CHF patient, which may shorten length of stay, improve functional status of discharged patient, and reduce rehospitalizations.
