The goal of this clinical trial is to evaluate the accuracy and feasibility of transdermal glomerular filtration rate (tGFR) assessment using relmapirazin (Lumitrace) and the MediBeacon tGFR system compared to plasma clearance measurement of GFR in adults with heart failure. The main question it aims to answer is the comparison of the transdermal-derived GFR for each participant using the MediBeacon tGFR to their nGFRBSA measurement. Participants will participate in a Screening visit that will take place within 15 days of the scheduled administration of Lumitrace and iohexol. On dosing day, participants will have the tGFR reusable sensor with disposable adhesive ring placed on their chest, and the MediBeacon Transdermal GFR System initiated to collect background fluorescence. Following an injection of Lumitrace and iohexol and the initiation of GFR assessments, participants will be followed at the study center for 10-24 hours. All participants will participate in a follow-up phone call approximately 7 days after the last exposure to Lumitrace and iohexol. Researchers will analyze the results to compare the tGFR values to the nGFRBSA measurements for each participant.

This study is an investigator-initiated, cluster-randomized implementation trial evaluating a large language model (LLM)-based clinical decision support (CDS) tool designed to improve guideline-directed medical therapy (GDMT) for adult patients with heart failure seen in outpatient cardiology clinics at Mass General Brigham. For eligible heart failure encounters, the CDS tool reviews existing electronic health record (EHR) data, including diagnoses, medications, vital signs, laboratory results, and recent notes, and generates brief, clinician-facing messages suggesting opportunities to initiate or optimize GDMT and highlighting relevant safety considerations. Messages are delivered to cardiology providers via Epic InBasket and/or institutional email prior to scheduled visits. The tool is advisory only and cannot place orders or change medications automatically; all treatment decisions remain at the discretion of the treating clinician and patient. Cardiology providers are assigned at the provider/clinic level to early implementation of the CDS tool versus usual care (no messages) during the initial phase. The primary outcome is GDMT optimization within 30 days of an index visit. Secondary outcomes include feasibility of CDS generation and delivery and a 30-day safety composite (e.g., heart failure hospitalization, acute kidney injury, hyperkalemia, hypotension or bradyarrhythmia plausibly related to GDMT).

The goal of this clinical trial is to treat both hypertension and obesity in adults using a food is medicine framework. Participants will be randomized 1:1 to FIM+DASH or usual-care control. The 24-week trial includes a 12-week FIM+DASH intervention followed by a 12-week maintenance period and leverages existing partnerships with community-based organizations for home food delivery and culinary skill-skill building. The main questions it aims to answer are: (1) What is the effect of FIM+DASH vs. usual care control on blood pressure? (2) What is the effect of FIM+DASH vs. usual care control on DASH diet adherence (diet quality), body weight, and waist circumference? (3) How to identify factors associated with the sustainability and scalability of FIM+DASH in real-world settings?

The goal of this interventional study is to evaluate the implementation, usability, and clinical outcomes of a wearable medical-grade device in a virtual Cardiac Rehabilitation (CR) program, titled HEARTS in Sync. The question guiding this study is: Do patient clinical outcomes differ between those who use the CardioWatch 287-2 during the HEARTS in Sync program as compared to those who participate without using the CardioWatch 287-2? The comparison will happen between two non-randomized groups of patients who are enrolled in the HEARTS in Sync virtual CR program. The wearable device (CardioWatch 287-2), worn on patient's wrists, will provide clinicians with physiological information to better mirror the clinical oversight provided to an in-person CR program. Participants who choose to use the device will be asked to wear it daily. The clinical team will review weekly summary reports to help guide participant progress through the 13-week program. The primary objectives of this study are to: 1. Characterize participants (e.g., demographic health history, patient feedback) between those who choose to use the CardioWatch 287-2 device and those who do not. 2. Compare clinical outcomes between users and non-users of the device within the HEARTS in Sync program, by: 1. Tracking patient enrollment, attendance in virtual education sessions, and program completion rates, 2. Evaluating change in patient bloodwork outcomes, 3. Measuring change is physical ability, 4. Analyzing changes in eating behaviours, and 5. Examining quality of life using validated tools. 3. Asses the feasibility of the CardioWatch 287-2 for the HEARTS in Sync virtual CR program by: 1. Assessing device adherence 2. Reviewing patient feedback survey, and 3. Determining if clinician team were able to access and interpret data collected throughout the program The secondary objective of this study is to compare clinical outcomes of device users during the HEARTS in Sync program with patients who completed the on-site CR program. This research aims to better understand how a medical-grade device may improve virtual CR programming to extend clinical care to the community. As a result, this could lead to a more personalized care and better results for patients.

Heart failure is a high-risk, chronic condition that impacts patients' mental health. Approximately 50% of heart failure patients experience comorbid mental health conditions, such as stress, depression and anxiety, which affect their day-to-day lives. Despite this interconnection, the integration of mental health awareness and support into cardiac care remains limited. To address this gap, the FRAME (Foundation, Recognition, Awareness, Management, Engagement) intervention was co-designed by researchers, healthcare providers, health system decisionmakers, and patient partners. This pilot study evaluates the feasibility of implementing the FRAME intervention in pilot clinical sites within two health regions in Ontario, Canada, including team-based family medicine clinics, cardiac rehabilitation/specialist clinics, and emergency departments. Utilizing a pretest-posttest hybrid 1 model intervention design, this study evaluates process indicators and patient-focused outcomes through surveys and semi-structured qualitative interviews. Findings from this study will inform a future large scale cohort study and scalable integration of the FRAME tool into existing cardiac care pathways to enhance mental health awareness and support among heart failure patients.

The goal of this study is to learn whether stopping beta-blockers can help older adults with heart failure with preserved ejection fraction (HFpEF) feel better and function better. This study will test whether "deprescribing" or stopping these medications in a careful, guided way can improve symptoms and quality of life. Participants will be randomly assigned to one of two groups: Deprescribing group: Beta-blockers are gradually reduced using capsules that contain decreasing doses. Usual care group: Beta-blockers are continued at the usual dose in look-alike capsules. All participants will: * Take study medicine for about 4 months * Have their blood pressure and heart rate monitored * Complete regular phone calls and questionnaires about how they are feeling This study does not involve any experimental medication. Participants active involvement in the study will last approximately 4 months. During these 4 months they will have 8 scheduled telephone visits.

The purpose of this research study is to understand the biology related to the potential shortcomings of existing anti-aldosterone therapy.

The overall objective of this study is to determine whether the addition of SGLT2 inhibitors to usual care in hospitalized patients with heart failure associated acute kidney injury is safe and efficacious. Investigators will assess if SGLT2 inhibition improves a composite cardio-renal outcome (mortality, dialysis, AKI progression, decongestion metrics, heart failure symptoms). Secondary objectives of this study are to compare individual components of the composite outcome as well as changes in biomarkers of kidney injury, inflammation, repair and oxidative stress between those exposed to the SGLT2 inhibitor vs placebo.

The goal of this clinical trial is to learn if increasing the dose of diuretics to achieve a higher urine sodium target produces better clinical results when treating patients hospitalized with acute heart failure when compared to lower urine sodium target and standard of care. The main questions it aims to answer are: 1. Does targeting a higher urine sodium goal achieve greater natriuresis and diuresis? 2. Does targeting a higher urine sodium goal reduce frequency of hospital readmissions? 3. Does targeting a higher urine sodium goal reduce hospital length of stay? Researchers will compare natriuresis-guided arms with standard of care to see if targeting higher natriuresis goals improves significantly over current practice. Participants will submit urine samples at routine intervals after being given diuretics to evaluate urine sodium concentration. If urine sodium is low then diuretic dose will be increased.

This study will look at whether using a phone app called StudyU can help people with Heart Failure with Reduced Ejection Fraction (HFrEF) reach their recommended dose on their beta blocker.

The goal of this interventional pilot study is to evaluate the feasibility, acceptability, and impact of medically tailored meals (MTM) on post-discharge recovery in patients with heart failure for Penn Medicine patients in Philadelphia and Lancaster through two pilots.

This study aims to validate the accuracy and reliability of blood pressure (BP) estimates obtained over 24 hours using a PPG-based chest-patch device compared to the gold standard ambulatory blood pressure monitoring (ABPM) method using an upper arm cuff-based oscillometric BP device, in both hypertensive and normotensive individuals referred by their provider to undergo a 24-hours ABPM for clinical indication. The Awake/Asleep test, which is the primary test recommended for automated wearable cuffless BP devices that are cuff-calibrated (based on the 2023 European Society of Hypertension (ESH) recommendations for the validation of cuffless blood pressure measuring devices), will be conducted in this study. The secondary aim of the study is to assess the feasibility and convenience of the PPG-based device.
