NCT01121107
The purpose of this clinical study is to evaluate the safety and clinical effectiveness of use of a physician-directed, patient self-management system, guided by left atrial pressure measurements, for use in patients with heart failure. The system allows patients to adjust their HF medications daily based on a physician-directed prescription plan and their current HF status, similar to the manner in which diabetes patients manage their insulin therapy. The goal of the LAPTOP-HF study is to demonstrate reductions in episodes of worsening heart failure (HF) and hospitalizations in patients who are managed with the left atrial pressure (LAP) management system (treatment group) versus those who receive only the current standard of care (control group).
NCT00709865
The purpose of the current study is to assess the safety and tolerability of intravenous tonapofylline.
NCT04998643
Background \& Significance. Children with congenital heart disease (CHD) have experienced improved postoperative survival shifting the focus away from minimizing mortality to curtailing morbidities. Critical illness following cardiac surgery induces catabolism which may impact functional status. Catabolism, a state in which protein breakdown exceeds protein synthesis, can lead to lean body mass (LBM) breakdown. LBM loss has been associated with poor clinical outcomes. Muscle ultrasound (mUS) has been utilized to measure LBM changes and the functional status score (FSS) was developed to assess functional status changes in children following hospitalization. The ability to identify LBM loss acutely and its association with FSS changes may lead to earlier interventions to preserve LBM and aid in outcome prediction. Specific Aims \& Hypotheses. Specific Aim 1 is to identify the percent change in LBM by mUS during the first postoperative week in children following complex cardiac surgery. Specific Aim 2 is to evaluate the relationship between percent change in LBM during the first postoperative week and the FSS at discharge and 6 and 12-month follow-up in children with CHD following complex cardiac surgery. The investigators hypothesize children with CHD following complex cardiac surgery will experience a decline in LBM and that there is a direct relationship between the change in LBM and postoperative FSS follow-up. Study Design \& Methods. The investigators are conducting a single-center, prospective, observational cohort study. Consecutive children (\> 3 months and \< 18 years of age) with CHD undergoing biventricular conversion will be enrolled. Patients will undergo a baseline mUS and FSS at the time of the index operation. Interval mUS will be obtained on the third and seventh postoperative day. Discharge mUS and FSS will be obtained and a remote FSS will be requested by the family at 6 and 12-months postoperatively. Demographics, pertinent laboratory, concomitant medications, nutrition and ultrasound variables will be collected. Outcomes. The primary outcomes will be change in LBM during the first postoperative week and change in FSS at 6 and 12-month follow-up in children following complex cardiac surgery. Change in LBM will be defined as a percent change in cross-sectional area of the quadriceps muscle layer thickness (QMLT). Change in FSS will be significant if the score drops 3 points or more from baseline at postoperative follow-up.
NCT01930214

NCT05322616
A phase 1, randomized, double-blind, placebo-controlled single-ascending dose study to assess JK07 in adult subjects with heart failure with preserved ejection fraction.
NCT02305095
The response to therapy with a fixed dose combination of isosorbide dinitrate and hydralazine (FDC I/H) is enhanced in African Americans with heart failure and reduced ejection fraction (HFrEF) when compared to similar white cohorts. This study will seek to confirm the previous genetic sub-study from AHeFT which suggested a functional polymorphism of guanine nucleotide binding protein beta polypeptide 3 subunit (GNB3), C825T in exon 10, influences the therapeutic efficacy of FDC I/H. This study will initiate treatment with FDC I/H in 500 self designated African American subjects with systolic heart failure. They will be followed for up to two years on therapy. Clinical outcomes (survival, heart failure hospitalizations, and change in quality of life) on FDC I/H will be compared by GNB3 genotype subset. The hypothesis to be confirmed is that subjects homozygous for the T allele (those with the GNB3 TT genotype which is present in approximately 50% of black subjects) demonstrate enhanced therapeutic benefit from FDC I/H.
NCT03759392
The purpose of this study is to evaluate the effect of treatment with omecamtiv mecarbil compared with placebo on exercise capacity as determined by cardiopulmonary exercise testing following 20 weeks of treatment with omecamtiv mecarbil or placebo
NCT02596087
The overall goal of the IQ-MAPLE project is to improve the quality of care provided to patients with several heart, lung and blood conditions by facilitating more accurate and complete problem list documentation. In the first aim, the investigators will design and validate a series of problem inference algorithms, using rule-based techniques on structured data in the electronic health record (EHR) and natural language processing on unstructured data. Both of these techniques will yield candidate problems that the patient is likely to have, and the results will be integrated. In Aim 2, the investigators will design clinical decision support interventions in the EHRs of the four study sites to alert physicians when a candidate problem is detected that is missing from the patient's problem list - the clinician will then be able to accept the alert and add the problem, override the alert, or ignore it entirely. In Aim 3, the investigators will conduct a randomized trial and evaluate the effect of the problem list alert on three endpoints: alert acceptance, problem list addition rate and clinical quality.
NCT00458926
Non-invasive positive pressure ventilation (NIV) refers to the provision of mechanical ventilation without an artificial airway (for example, an endotracheal tube). Over the past decade, evidence from randomized control trials has accumulated to demonstrate effectiveness of the technique in avoiding intubation, reducing complications associated with intubation, shortening ICU and hospital lengths of stay, and reducing mortality rates in selected patients with acute respiratory failure. However, NIV is still underutilized at many medical centers. The purposes of this project will be to acquire information related to NIV use, to identify reasons for underutilization, to implement interventions that encourage more appropriate use of NIV, and to evaluate the effectiveness of the interventions. Reliable information on NIV use as well as analysis of reasons for underutilization will provide insight into ways of enhancing NIV use. We will determine utilization rate, technology used, patient diagnoses, duration of ventilator use and hospital stay, and success rates as recorded on case report forms (CRFs). After completing the survey, we will provide an educational program to randomly selected institutions (one-half of the total) aimed at increasing the knowledge and skill of physicians, nurses, and therapists regarding use and implementation of NIV. Data will be gathered for a second round with the same data-gathering instruments used during
NCT01807897
The purpose of this study is to compare three treatment modalities for central, or mixed obstructive and central, sleep apnea in patients with chronic heart failure and reduced ejection fraction. The modalities to be tested are nocturnal supplemental oxygen (NSO) and continuous positive airway pressure (CPAP). The main outcome measures will be left ventricular ejection fraction on echocardiogram and peak oxygen consumption on cardiopulmonary exercise testing.
NCT01431326
Understudied drugs will be administered to children per standard of care as prescribed by their treating caregiver and only biological sample collection during the time of drug administration will be involved. A total of approximately 7000 children aged \<21 years who are receiving these drugs for standard of care will be enrolled and will be followed for up a maximum of 90 days. The goal of this study is to characterize the pharmacokinetics of understudied drugs for which specific dosing recommendations and safety data are lacking. The prescribing of drugs to children will not be part of this protocol. Taking advantage of procedures done as part of routine medical care (i.e. blood draws) this study will serve as a tool to better understand drug exposure in children receiving these drugs per standard of care. The data collected through this initiative will also provide valuable pharmacokinetic and dosing information of drugs in different pediatric age groups as well as special pediatric populations (i.e. obese).
NCT05310877
Heart failure (HF) represents a significant public health concern. Medication non-adherence represents a modifiable contributor to costly hospital readmissions in older adults with HF. Educational interventions improve, but do not eliminate, non-adherence. Values affirmation interventions which invite individuals to reflect on core values may encourage better engagement in health behaviors by increasing the personal relevance of targeted behaviors. Similar interventions have promoted weight loss, increased adherence and physical activity, and more frequent fruit and vegetable consumption in a variety of contexts and populations. This study seeks to test a recently developed values-affirmation intervention targeting medication adherence in older adults with HF enrolled in cardiac rehabilitation (CR). The purpose of this feasibility study is to test methodology to aid development of a subsequent randomized controlled pilot trial to examine preliminary efficacy.

NCT05319236
Subjects will use the Gabi system on a daily basis for 3 months, each time the subject is resting or asleep. The Gabi system will recording the SpO2, pulse rate, respiratory rate and movements of the subject. The objective of this study is to perform a first assessment of the range of most potentially clinically relevant indications for use of the Gabi system for children \< 6 years old with underlying medical conditions. This is performed by asking HCPs to review the data measured by the Gabi system after taking a medical decision independently from the Gabi data and to assess the potential clinical utility of the Gabi system. The usability of the system will also be assessed throughout questionnaires filled out by the HCPs and by the caregivers. \*During this study, the data collected by the Gabi system are not intended to be used by caregivers or HCPs to take any (medical) decisions.

NCT00251251
Congestive heart failure (CHF) is a common health problem that leads to frequent hospitalizations and an increased death rate. In spite of advances in drug therapy, it remains a significant public health problem. Recently, a new therapy has been developed for advanced heart failure patients with a ventricular conduction abnormality. This new therapy, called cardiac resynchronization (CRT), is a device which stimulates the atrium, the right ventricle, and the left ventricle providing synchronization of the contraction of the heart chambers. It is the addition of this therapy to an implantable cardioverter defibrillator (ICD) that will be evaluated in this study. This study will compare whether the implantation of this new therapy device, in combination with an implantable cardioverter defibrillator, will reduce total mortality and hospitalizations for CHF.
