Heart Failure Clinical Trials

This study will enroll heart failure (HF) patients who are under active management with an implanted pulmonary artery pressure sensor (CardioMEMS). Subjects will be provided an electronic stethoscope (the Eko DUO) to take at-home heart sound, lung sound, and ECG recordings in conjunction with regimented CardioMEMS measurements. These two datasets will be used to confirm whether an AI/ML model to track HF status can be developed. Read Less

Cardiac remote monitoring devices have expanded our ability to track physiological changes used in the diagnosis and management of patients with cardiac disease. Implantable remote monitoring technologies have been shown to predict heart failure events, and guide therapy to reduce heart failure hospitalizations. The CardioMEMs System, the most studied and established remote monitoring system, relies on a pulmonary artery implant for continuous PAP measurement. However, there are no commercially available wearable systems that can reproduce continuous PAP tracings. This study aims to determine if a machine-learning algorithm with data from a wearable cardiac remote-monitoring system incorporating EKG, heart sounds, and thoracic impedance can reproduce a continuous PAP tracing obtained during right heart catheterization.

The MyLeukoMAP™ Pivotal Clinical Study will assess the accuracy of MyLeukoMAP™, a new molecular blood test, performed within 30 days before scheduled surgical / interventional therapies for Heart Failure, to determine its effectiveness in improving clinical decision support by providing a quantitative prediction of low, indeterminate, or high risk of death one year after surgical / interventional therapies that is not identified by current diagnostic tools.

Heart failure (HF) with preserved left ventricular function (pEF) is difficult clinical syndrome to treat effectively with few evidence based therapies. Atrial fibrillation (AF) is now an important co-morbidity being observed in 43% of patients with HFpEF. Rhythm control has not been studied in this population. Catheter ablation and antiarrhythmic drugs are rhythm control therapies that have been used for treatment of AF without HF or HF with reduced systolic function but have not been widely applied in HFpEF. No controlled comparative evaluation has been performed in HFpEF. The introduction of wireless pulmonary artery hemodynamic monitoring has permitted optimization of HF therapy in patients with chronic HF with reduced and preserved EF. Reduction in HF hospitalizations has been observed in post hoc analyses of HFpEF patients but has not been systematically applied in AF patients with HFpEF. In this study, we propose to study both rhythm control and optimized HF therapeutic approaches in an AF with HFpEF study population in a pilot study using a sequential two phase randomized controlled clinical trial design.

This initiative supports a quality improvement effort evaluating the use of strategies (including technology-based decision support, referral to a virtual GDMT team, and general educational tools/resources for clinicians and patients) to improve use of guideline-directed therapeutics known to lower cardiovascular (CV) events among patients with cardiovascular diseases of heart failure, atrial fibrillation and type 2 diabetes (T2D)/ASCVD with a specific focus on underserved populations and those with a history of health care disparities.

Overall Research Strategy of this protocol is to refine and validate noninvasive CMR imaging sequences with invasive hemodynamic and pathology results to create a comprehensive, noninvasive, radiation-reduced regimen for pediatric cardiomyopathy and cardiac transplant assessment. We were the first to perform MR-guided cardiac catheterization in US children, and have accumulated the largest US experience, having performed over 75 procedures to date. Our unique experience puts us in strong position to leverage this technology to improve care of children with cardiomyopathy and transplant. Using an integrated approach, we will simultaneously (1) validate imaging measures of cardiac edema and fibrosis by correlating T1 and T2 map images with endomyocardial biopsy (EMB) results in Aim 1; (2) overlay T1, T2 map images into our x-ray system to display "hotspots" of T1 and T2 abnormalities to guide EMB in Aim 2; and (3) obtain radiation-free hemodynamic data in a highly vulnerable pediatric population by using CMR to guide catheter manipulation in the ICMR suite in Aim 3. Age and diagnosis-matched historical controls will be identified from the last 10 years at Children's National as a control population for specific purposes of comparing (1) EMB yield without image overlay and (2) Radiation exposure during X-ray guided right heart catheterization. Identical information will be obtained and stored in the same 45CFR compliant database. Historical controls will be identified from the cardiac catheterization database by searching for age and diagnosis. A waiver of consent will be applicable here, as it would be inconvenient, insensitive and not feasible to consent families who have already undergone treatment. Read Less

The primary objective of this pilot study is to document the percentage achievement in effective HR control (average nighttime HR < 70 bpm) during WCD use in a cohort of female patients with cardiomyopathy in an outpatient setting using continuous heart rate (HR) trends data from the WCD to optimize BB/ivabradine dosage, as compared to a prior historical control.

This is a multicenter, randomized, double-blind, placebo-controlled, dose-response trial in patients with chronic stable Heart Failure (HF) and reduced Left Ventricular Ejection Fraction (LVEF) to evaluate the efficacy and safety of three INL1 doses compared with placebo. Patients will be treated for approximately 12 weeks with one of three INL1 doses: 50 mg, 150 mg, 300 mg, or, placebo capsules, taken twice daily (BID). Read Less

In this study, the investigators will compare the accuracy of the Biostrap wristband, a wearable device with a clinical-grade Photoplethysmography (PPG) sensor, to measure ejection fraction and cardiac output in patients undergoing a cardiac ultrasound and pulmonary arterial catheterization, respectively.

The development of symptomatic heart failure is frequently preceded by a pre-clinical period of structural remodeling in the heart. The remodeling process driving this transition, however, remains poorly understood. The investigators hypothesize that imaging the diffusion of water in the heart with MRI will allow its microstructure to be resolved. The investigators further hypothesize that the characterization of microstructural changes in the heart will help elucidate the pathogenesis of heart failure and the transition from a compensated to a decompensated state. Patients with recent myocardial infarcts and left ventricular hypertrophy, who are at risk for the development of heart failure, will be enrolled. The participants will undergo serial diffusion tensor MRI (DTI) imaging of the heart to characterize changes in myocardial microstructure over time. Read Less

The study aims to test the hypothesis that multi-omics studies can identify Heart Failure profiles at risk of adverse outcomes and evaluate a telemonitoring intervention in the optimization of guideline-directed medical therapy. Read Less

Anthracycline chemotherapies (e.g. doxorubicin, daunorubicin) are commonly given to treat pediatric cancer, and carry a risk of cardiotoxicity. Over the long term, children who receive these therapies have an increased risk of heart failure and early cardiovascular death. However, current strategies for identifying patients who are at risk prior to the development of significant changes in heart function are limited. This study will focus on imaging markers of cardiac injury and dysfunction with the goal of developing improved diagnostic tests and treatment strategies. Read Less
