This study is an early feasibility study which typically consist of evaluating innovative devices or innovative uses of approved devices. The purpose of this study is to see if an investigational device called preCARDIA Intermittent Balloon Device can limit fluid overload in congested patients with advanced heart failure. This investigational device is a catheter which has been approved by the U.S. Food and Drug Administration (FDA) to occlude large vessels but not for the treatment of advanced heart failure. Currently, there are no device-based approaches that are FDA-approved for advanced heart failure. This study will help find out if this device-based approach can improve symptoms and heart function in congested patients with advanced heart failure
The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics (the levels of drug in the blood) and pharmacodynamics (the effect of the drug on your body) of the study drug, MYK-491, when administered orally twice a day for about one to two weeks.The study will recruit patients with an enlarged heart and weakened heart muscle not caused by heart damage from a heart attack or heart valve problem. Eligible patients must also have a specific genetic mutation called MHY7. All subjects that qualify will receive MYK-491 (no placebo, or inactive pill will be dispensed during the study). The study medication is designed to improve cardiac contractility or the ability of the heart to squeeze.
This study has two treatment periods during which multiple doses of MYK-491 (the study drug) will be administered. Once Treatment Period 1 is completed, participants will return to the clinical site for study assessments and to obtain a dose for Treatment Period 2. The investigator will review the results of the study assessments and participants will learn if they will receive a lower or higher dose of MYK-491 for Treatment Period 2 than they received in Treatment Period 1. The expected study duration ranges from about 4 weeks to 11 weeks, including about 1-8 weeks for screening, 9 to 15 days for IMP dosing and an approximately 1 week (7
We will recruit patients with atrial fibrillation during office visits and at time of elective direct current cardioversions.
We will record 15 minutes of ECG data and data from the Mindmics earbuds during office visit or prior to and after cardioversion.
We will use the recorded data to formulate algorithms to discern atrial fibrillation from normal sinus rhythm.
This is a prospective, multicenter clinical trial for individuals presenting to the Emergency Department with suspicion of acute heart failure. A blood sample collected will be used to compare the standard of care BNP test used at the local site to the investigational assay from Beckman Coulter (sponsor).
The diagnosis and treatment of patients at each site will use an FDA-cleared BNP or NT-proBNP assay under the site's standard of care and NOT the investigational assay.
The purpose of the study is to evaluate the safety and how well the V-Wave Interatrial Shunt works. The study will also look at information obtained from the tests performed to see if subjects have improvement in symptoms of heart failure. Participation in this study will last approximately 1 year to up to 7 years depending on randomization group. During the study period subjects will be asked to attend regular study visits with the research coordinator. These visits will include such activities as blood tests, questionnaires, physical evaluation by a study doctor, echocardiogram, and 6 minute hall walks. There will be a minimum of 10 or up to 15 planned research clinic visits. Subjects will have 1 overnight hospital stay for the study related RHC and research procedure. Each participant will receive a phone call between all study visits.
Subjects will have a 50:50 chance of receiving the Shunt during the randomization procedure (like the flip of a coin). Neither the subject, nor the blinded study doctor or blinded study coordinator will know which group subjects are in. Participants will be randomized to either the treatment group (and receive the Shunt) or the control group (and not receive the shunt). Neither the subject nor the study doctor will decide what group subjects are assigned.
This research study aims to determine a less invasive way to assess heart function by taking measurements of the heart while subjects are performing an exercise cardiac MRI. Subjects will undergo two exercise phases and MRI measurements will be taken after each exercise phase. These measurements will be compared to available clinical data (including demographic, hemodynamic, radiologic, and functional) and future outcome data.
This is a study for patients with high blood pressure. The purpose of this study is to evaluate the safety and effectiveness of renal denervation while you are still on your blood pressure medications. Renal denervation is a procedure that destroys the nerve fibers that run along the kidney blood vessels interrupting nerve signals that may cause high blood pressure.The purpose of the treatment (renal denervation) is to lower blood pressure. You will undergo renal angiography (RA), which you may or may not receive the study treatment (depending upon your study assignment). The sponsor has manufactured a new drug/device combination product called the Peregrine System™ Kit (also referred to as the Peregrine Kit). The Peregrine Kit contains a device, the Peregrine System™ Infusion Catheter (also referred to as the Peregrine Catheter), and a drug dehydrated alcohol for injection (also referred to as alcohol). Therefore, the effectiveness of the study catheter and the alcohol (Peregrine Kit) will be assessed by how well the treatment reduces your blood pressure. The participant will be asked to return to the doctor's office for follow-up visits at 4 and 8 weeks, 3, 4, 5 and 6 months, and 1, 2, and 3 years after the procedure. At the 1 year visit, the participant will find out if he/she got the treatment, and if he/she did not, they can choose to cross-over to the treatment if they still meet eligibility criteria.
The purpose of this study is to build a repository (collection) of heart signals from eligible subjects. The experimental part of this study is the collection of heart signals using a device similar to a heart monitor called the Phase Signal Acquisition System. The signals will be electronically sent to a storage center and paired with the subject's heart catheterization results for future use in research and development activities sponsored by Analytics 4 Life. The study will include up to 1500 participants at up to 20 research sites in the United States and will require approximately one hour of the subject's time. There are no follow-up visits. .

The experimental part of this study is the collection of the participant's heart signals using a device similar to a heart monitor called the Phase Signal Acquisition System. The signals will be electronically sent to a storage center, then compared to the results of the participant's heart catheterization and saved for future research and development activities sponsored by Analytics 4 Life. The study will include up to 2500 participants at up to 20 research sites in the United States and will require approximately one hour of the subject's time. There are no follow-up visits.
The proposed study will investigate the effect of congenital heart disease (CHD) on rates of employment, community participation, neuro-psychological comorbidities, and quality of life (QOL) in adults with Down syndrome. Knowledge of these longitudinal functional outcomes may assist clinician guidance to families and highlight needs for specific resources and interventions to achieve optimal outcomes in adulthood.
