NCT05134012
This a Phase 3, prospective, open-label, multicenter study of \[15-O\]-H2O injection for PET imaging of subjects with suspected CAD. Approximately 182 evaluable participants with suspected CAD referred for testing will be included in the study at approximately 10 study sites in the United States and Europe. Approximately 215 participants will be enrolled to account for an estimated 15% drop-out rate. Screening assessments will occur prior to enrollment to confirm eligibility. All participants will receive two doses of \[15-O\]-H2O as part of a single PET imaging session (one dose at rest and one during pharmacological stress with adenosine). A safety follow-up phone call will occur 24 ± 8 hrs after completion of the \[15-O\]-H2O scan.
NCT06691191
Ticagrelor currently represents the most tested and commonly used P2Y12 inhibitor monotherapy following percutaneous coronary intervention. The purpose of this study is to conduct a head-to-head comparison on the pharmacodynamic efficacy of ticagrelor-based and prasugrel-based single antiplatelet therapy. To determine if the PD profiles of ticagrelor- and prasugrel-based SAPT are comparable, we aim to conduct a non-inferiority study between the two strategies.
NCT05879887
Using a highly innovative methodology, the Multiphase Optimization Strategy (MOST), the purpose of this randomized factorial pilot trial is to identify feasibility, acceptability, and preliminary efficacy of components of an intervention (UPHOLDS) to improve quality of life of older adults with advancing heart failure. Using a 2x2x2x2 factorial design, 64 adults with advancing heart failure will be randomized to receive one or more palliative care coach-delivered components, based on Ferrans' Health-Related Quality of Life Model: 1) psychoeducation on palliative care principles (4 vs. 8 sessions); 2) financial coaching (yes vs. no); 3) one-time specialty outpatient palliative care consultation (yes vs. no); and monthly follow (1 monthly follow-up call vs. monthly follow-up calls for 24 weeks).
NCT04698291
Inflammation is the way that the body reacts against infection, injury or illness. An uncontrolled inflammatory response can lead to the development of inflammatory diseases, such as rheumatoid arthritis and cardiovascular conditions. Recent studies have shown that inflammation is a regulated process coordinated by a group of molecules known as specialized pro-resolving mediator (SPM). These molecules are produced by enzymes via the enzymatic conversion of essential fatty acids; whereas their biological actions are mediated by proteins expressed on the surface of cells known as receptors. Given the central role that pro-resolving mediators play in regulating the immune response, the aim of this study is to investigate whether there are genetic variants (mutations) in genes encoding for enzymes and receptors involved in the biology of these molecules and to determine how these mutations affect SPM's activity or function. Findings made as part of these studies will help shed light into mechanism influencing disease onset and/or progression and potentially enhance the discovery of new and more effective treatments.
NCT04575883
Congenital heart disease (CHD), the most common birth defect, is present in nearly 1% of the population. CHD patients are associated with intense resource utilization and premature death in adulthood. The risk of premature death is linked with reduced exercise capacity, a finding consistently noted in youth with CHD. Reduced exercise capacity in this population has also been associated with reduce physical activity and health-related quality of life. Cardiac rehabilitation (CR) in adults with acquired heart disease is an established secondary prevention strategy that improves exercise capacity. The investigators propose a prospective clinical trial of a home-based high intensity interval training (HIIT) program using a novel telemedicine-equipped video game-linked cycle ergometer (MedBIKE™) for 10 to 18 year olds with repaired moderate-complex CHD. The pilot study with the MedBIKE has shown promising results. The investigators now seek to study the efficacy of this program in a broader CHD population.
NCT06229678
The study team will examine the effects of elevated plasma ketone levels following initiation of SGLT2 inhibitor therapy in high-risk type 2 diabetes mellitus (T2DM) individuals with heart failure (HF) with reduced ejection fraction (HFrEF) providing an energy-rich fuel that is taken up with great avidity by the myocardium, to measure change in Left Ventricle diastolic and systolic function
NCT07390994
To investigate whether pre-procedural OCT-derived de novo coronary lesion phenotype (lipid-rich, fibrotic, calcific; and ACS mechanisms such as plaque rupture/erosion/calcified nodule) is associated with clinical outcomes after DCB angioplasty.
NCT07390903
The goal of this observational study is to learn whether global longitudinal strain (GLS), measured by echocardiography, can predict difficulty separating from cardiopulmonary bypass (CPB) in adults undergoing elective cardiac surgery. The main questions it aims to answer are: * Can preoperative GLS measurement predict difficult separation from CPB? * Are GLS values associated with outcomes such as intensive care unit (ICU) stay, hospital stay, cardiac biomarkers, or 30-day mortality? Participants will: * Undergo standard cardiac surgery requiring CPB * Have echocardiographic assessments (TTE before and after surgery) * Have their recovery and outcomes monitored, including ICU and hospital stay, postoperative labs, and survival within 30 days
NCT05592275
The main purpose of this study is to assess the efficacy and safety of LY3540378 in adults with worsening heart failure with preserved ejection fraction
NCT03491423
Recommendations for cardiovascular rehabilitation (CVR) encourage exercise training, primarily involving the aerobic system, to allow patients to regain independence in daily activities. However, the lactic anaerobic process is also involved during these activities (stair climbing, carrying loads, etc.). Hence there is a major interest in accurately assessing patients' anaerobic capacities in order to tailor suitable exercise programs. However, there are no functional tests specifically dedicated to the evaluation of lactic anaerobic metabolism and adapted to people with coronary disease. The investigators offer a dedicated test, the short and fast test (SFST), which can be applied in current clinical practice and has already been evaluated in a population of healthy subjects. The purpose of this project is to evaluate the safety, feasibility and validity of SFST in a population of patients with coronary artery disease.

NCT07379112
This study, called the EuroDafodil Registry, is being conducted to understand how safe and effective the Dafodil™ and Dafodil Neo™ Pericardial Bioprosthetic heart valves are when used in routine medical practice. The registry includes adult patients (18 years or older) who require surgical replacement of their aortic or mitral heart valve, either because their natural valve is severely diseased or because a previously implanted valve is no longer working properly. All patients in this registry will receive a Dafodil™ heart valve as part of their standard surgical treatment. No experimental procedures are involved beyond usual clinical care. This is a prospective, multi-centre registry being conducted at approximately 50 hospitals across Europe, with a planned enrollment of at least 500 patients. The study does not compare treatments; instead, it follows patients who receive the Dafodil™ valve to collect real-world information on outcomes. Doctors will monitor patients during their hospital stay and through regular follow-up visits at 1 or 3 months, 1 year, 3 years, and up to 5 years after surgery. Information collected includes survival, heart valve function, complications such as blood clots or infections, heart performance on echocardiography, and quality of life. Participation in this registry is voluntary. All patients must provide written informed consent before joining. Patient privacy will be protected: personal identifiers will not be shared, and data will be coded so individuals cannot be directly identified. The results of this registry will help doctors and health authorities better understand the long-term safety, performance, and durability of the Dafodil™ heart valves in real-world clinical use.

NCT07349797
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.
NCT07379840
This is an observational study in which data from people with chronic heart failure (HF) with left ventricular ejection fraction (LVEF) ≥ 40%. who will be receiving finerenone are studied. The study is conducted to check the safety of finerenone after it is approved and available in South Korea. Observational studies use data that are collected as part of routine medical care and participants do not receive any advice or any changes to healthcare as part of the study. In this study, the data will be collected from participants who are receiving their usual treatment with finerenone as prescribed by their doctor according to the approved product information. Heart failure with LVEF ≥ 40% is a condition which occurs when the left side of the heart does not pump blood out to the body as well as it should. Over time, the body does not get the amount of oxygen it needs. This can lead to shortness of breath and tiredness, making it difficult for people to do their daily tasks. The study drug, finerenone, is already approved for doctors to prescribe to people with chronic heart failure. It works by blocking a specific receptor in the body called the mineralocorticoid receptor (MR). This helps reduce harmful effects in the heart, kidneys and blood vessels. Finerenone is different from older medicines in this group because it is more selective and may have fewer side effects, such as problems with the kidneys or high potassium levels in the blood. The participants in this study will receive finerenone as prescribed independently by their doctors during routine practice according to the approved product information. There have been studies in which researchers studied the effect and safety of finerenone in participants with chronic heart failure with LVEF ≥ 40%. These studies, however, included only a small number of South Korean participants. In this study, researchers will specifically gather data from South Korean participants to further understand the safety of finerenone. The main purpose of this study is to learn more about how safe and effective finerenone is in adults with chronic heart failure with LVEF ≥ 40% in South Korea within approved local label when used in everyday medical practice. To do this, researchers will collect any side effects or health problems that happen while patients are taking finerenone, and whether they are related to finerenone. In addition, doctors will also look at how well finerenone works by measuring: * Changes in investigator's treatment satisfaction with the treatment over time, including improvements in symptoms, quality of life and overall health status. * Time to dose change of finerenone (for example, increasing the dose if needed). Data will be collected from participants over one year after they enroll in the study or until they choose to leave the study. The data will come from participant's medical records or by interviewing the patient. In this study, only available data from routine care will be collected. No visits or tests are required as part of this study.
