NCT04356027
The purpose of the FUSION study is to validate the diagnostic performance of Virtual Flow Reserve (VFR) by comparing it against a reference standard, fractional flow reserve (FFR).
NCT02787785
The MADIT S-ICD trial was designed to evaluate if subjects with a prior myocardial infarction, diabetes mellitus and a relatively preserved ejection fraction of 36-50% will have a survival benefit from receiving a subcutaneous implantable cardioverter defibrillator (S-ICD) when compared to those receiving conventional medical therapy. The trial enrollment was stopped in 2018 due to lower than expected enrollment, all subjects enrolled at that time were followed for approximately 5 years.
NCT03507777
The objective of this prospective, single-blind clinical investigation is to demonstrate the superiority of an Optical Coherence Tomography (OCT)-guided stent implantation strategy as compared to an angiography-guided stent implantation strategy in achieving larger post-PCI lumen dimensions and improving clinical cardiovascular outcomes in patients with high-risk clinical characteristics and/or with high-risk angiographic lesions.
NCT03153111
This is a study to evaluate whether macitentan is an effective and safe treatment for patients with heart failure with preserved ejection fraction (HFpEF) and pulmonary vascular disease. The primary objective is to evaluate whether macitentan 10 mg reduces N-terminal pro-brain natriuretic peptide (NT-pro-BNP) as compared to placebo in these patients.
NCT04766892
This is a Phase 2a proof-of-concept study to assess safety, tolerability, and preliminary efficacy of mavacamten treatment on biomarker levels in participants with heart failure with preserved ejection fraction (HFpEF) and elevation of NT-proBNP with or without elevation of cTnT. Data from this study will inform future study designs of mavacamten in patients with HFpEF.
NCT05202509
This study will be a placebo-controlled, double-blind, randomized, phase 3 study in participants with Atherosclerotic Cardiovascular Disease (ASCVD) who are not adequately controlled despite maximally tolerated lipid-lowering therapy.
NCT03517111
The purpose of this study is to test if a parenting program can be used to prevent substance use among Latino youth and at the same time promote healthy eating. Pairs of 7th grade students and one of their parents will be enrolled in the study and randomly assigned to three groups: an existing parenting intervention focusing on substance use prevention (FPNG), the enhanced parenting intervention that also has nutrition content (FPNG+), and a comparison program focused on academic success. Only parents will attend intervention sessions. Data will be collected from the parent and their 7th grade student to see how these programs impacted substance use, nutrition, and parenting. The investigators hypothesize that families receiving the FPNG+ will have improved nutrition habits than the other conditions. Students in both FPNG and FPNG+ will have lower substance use rates as compared to the academic success program. In addition, the effects of parenting strategies and sociocultural factors on the FPNG and FPNG+ results will be studied.
NCT04451044
Multi-center, prospective, randomized controlled study comparing PCI guided by angiography versus iFR Co-Registration using commercially available Philips pressure guidewires and the SyncVision co-registration system, employing an adaptive design study for interim sample size re-estimation.
NCT03210402
New therapy tested in heart failure with preserved ejection fraction (HFpEF) patients with approved indications for pacing to determine if elevated pacing therapy is tolerated and whether there is a signal for efficacy.
NCT03476187
Subjects meeting the inclusion/exclusion criteria will wear the µCor for at least 90 days. During the study, clinic follow up will occur every 30 days. For all subjects, each scheduled clinic visit will include assessment of cardiac symptoms and any relevant clinically actionable events. The subject will be given a daily diary to track symptoms, unplanned hospital visits, medication changes, and all other heart failure related clinical events. Weekly phone calls to the subject will be given throughout the duration of the study to remind the patient to use the subject diary and to collect and record heart failure related clinical events. Subjects will be contacted six months and one year from initial enrollment to assess the vital status of the subject, any heart failure related clinical events since the end of µCor wear, and any health care utilization since the end of µCor wear.
NCT04096040
To assess investigator engagement of μCor system data in the context of heart failure management. The μCor system includes a sensor and wearable patch for fluid management.
NCT00826280
Observe whether the administration of caffeine prior to regadenoson will affect the interpretation of test results in subjects with coronary artery disease (CAD) undergoing SPECT MPI
NCT04141891
This Stage II randomized, controlled, longitudinal trial seeks to assess the acceptability, feasibility, and effects of a driving decision aid use among geriatric patients and providers. This multi-site trial will (1) test the driving decision aid (DDA) in improving decision making and quality (knowledge, decision conflict, values concordance and behavior intent); and (2) determine its effects on specific subpopulations of older drivers (stratified for cognitive function, decisional capacity, and attitudinally readiness for a mobility transition). The overarching hypotheses are that the DDA will help older adults make high-quality decisions, which will mitigate the negative psychosocial impacts of driving reduction, and that optimal DDA use will target certain populations and settings.
NCT03153137
The primary objective is to assess the effect of macitentan 10 mg as compared to placebo on exercise capacity through cardiopulmonary exercise testing.
NCT02178943
Plasma donor-derived cell-free DNA (dd-cfDNA) is measured as a % of the total plasma cfDNA in association with the measurement of AlloMap, a non-invasive gene expression test to aid in heart transplant management.
NCT06018194
The goal of this study is to evaluate the diagnostic accuracy of a novel plaque-based coronary CT angiography (CCTA) fractional flow reserve (FFRct) software device for the estimation of invasive fractional flow reserve (FFR). Researchers will compare the Elucid plaque-based FFRct analysis to invasively measured FFR in patients who have previously undergone CCTA and invasively assessed FFR.
NCT03533517
This is a non-randomized, prospective, multi-center Early Feasibility Study to evaluate the AccuCinch® Ventricular Restoration System in Patients with Heart Failure and Reduced Ejection Fraction (HFrEF).
NCT02806570
This is a multi-center, non-randomized, prospective Early Feasibility Study to evaluate the AccuCinch® Ventricular Restoration System in patients with symptomatic heart failure and concomitant functional mitral regurgitation that have stable symptoms on guideline-directed medical therapy
NCT04985773
The objective of this study is to evaluate safety and effectiveness of the Lacrosse NSE ALPHA coronary dilatation catheter during PCI in subjects with stenotic coronary arteries.
NCT02984124
This multicenter RCT of 200 hospitalized patients and their family members evaluates an "informed assent" approach to discussing cardiopulmonary resuscitation, compared to usual care, in older seriously ill hospitalized patients with severe life-limiting illness or severe functional impairment.
