The GUIDE-HF IDE clinical trial is intended to demonstrate the effectiveness of the CardioMEMS™ HF System in an expanded patient population including heart failure (HF) patients outside of the present indication, but at risk for future HF events or mortality.
NCT02646475
The overall purpose of this study is to learn more about the metabolic effects of angiotensin-(1-7) in the insulin resistant state associated with obesity. Pharmacologic approaches to increase angiotensin-(1-7) levels or its actions are currently in development for treatment of metabolic-related diseases such as obesity and type II diabetes, based on findings from animal studies. It is unclear if this peptide contributes to the regulation of metabolism in humans. The investigators will test if angiotensin-(1-7) infusion can improve insulin sensitivity measured by hyperinsulinemic-euglycemic clamp methods in individuals with obesity and insulin resistance. The investigators will also examine for changes in blood pressure and related hemodynamic and hormonal changes following angiotensin-(1-7) infusion.
NCT04847557
The main purpose of this study is to assess the efficacy and safety of Tirzepatide (LY3298176) in participants with heart failure with preserved ejection fraction and obesity.
NCT06062329
Evaluation of the Safety and Efficacy of the Symphony Thrombectomy System in the Treatment of Pulmonary Embolism
NCT02922036
This study is a prospective, multi-center, pivotal trial to study the safety and efficacy of the WiSE-CRT System for Cardiac Re-synchronization Therapy.
NCT03089398
The purpose of the study is to learn which treatment option is better for patients who have multi-vessel coronary artery disease (blockages in more than one vessel supplying blood to the heart muscle). The treatment options this study will compare are: (1) Hybrid Coronary Revascularization \[HCR\] (a combination of surgery and catheter procedures to open up clogged heart arteries) and (2) Percutaneous Coronary Intervention \[PCI\] (catheter procedures alone to open up clogged heart arteries). There are no new or "experimental" procedures being tested in this study: both HCR and PCI are well-established procedures and are regularly performed in patients who have coronary artery disease. But, the FDA has not approved the drug-eluting stents used in PCI for all types of coronary artery disease. We have received an Investigational Device Exemption from the FDA to use the drug-eluting stents in this trial in the same way that they are used in clinical practice. The study being proposed here will use rigorous scientific methods and should result in a very high level of certainty about which procedure is best for patients with coronary artery disease.
NCT02235545
The purpose of this post approval study is to characterize the chronic performance of the SJM Optisure family of HV leads in patients.
NCT04573660
The AV-MDR is a prospective, non-randomized, open-label, multi-center registry. The purpose of the AV-MDR study is to proactively collect and evaluate clinical data on the usage of the devices in scope within their intended use with the aim of confirming safety and performance throughout their expected lifetime, ensuring the continued acceptability of identified risks, detecting emerging risks on the basis of factual evidence, ensuring the continued acceptability of the benefit-risk ratio, and identifying possible systematic misuse or off-label usage such that the intended use can be verified as appropriate.
NCT04907526
Researchers want to better understand what happens to the heart when the autologous (from one's own body) stem cells are injected directly into muscle of the right side of the heart during the Fontan (Stage III) surgery. They want to see if there are changes in the electrical activity, the structure, and the function of the heart following this stem cell-based therapy. Researchers will compare the results from people who receive the stem cells to the results from people who do not receive the stem cells.
NCT06944509
The Azurion R4.0 is developed by Philips Medical Systems Nederland B.V., a Philips Healthcare company. The Azurion is an interventional X-ray system which is used for live X-ray imaging during invasive cardiac procedures. The proposed Azurion R4.0 includes new x-ray image postprocessing (Xres5) compared to its predecessor, which was equipped with ClarityIQ image post-processing (Xres4). Azurion R4.0 is a cleared device for EU-MDR regulated countries, submission for FDA510K clearance in the US is pending. Sites in the US will only be activated in the study after FDA clearance. This is a prospective, randomized, unblinded, comparative, international, multi-center clinical investigation. Randomization will be 1:1 between Xres5 and ClarityIQ (Xres4). Stratification will be performed per site on intended procedure type (based on clinical presentation) and patient BMI. Primary objective is to demonstrate that in coronary procedures, Xres5 can reduce overall patient radiation dose compared to the current ClarityIQ without affecting procedural performance. It is expected that 824 subjects are necessary to collect sufficient data for the evaluation of the objectives of this clinical study. The enrollment period is expected to last for 12 months. The study will be executed in Spain, Czech republic, Denmark and the US.
NCT03066050
This study is a continuation of two previous studies --- the Severe Ischemic Mitral Regurgitation (SMR) Trial (NCT00807040) and the Moderate Ischemic Mitral regurgitation (MMR) Trial (NCT00806988) --- to learn more about patients' health 5-10 years after their mitral valve surgeries. The investigators will collect long-term health information on SMR and MMR trial participants using electronic medical records, patient and/or family input, public records, and healthcare- and vital status-related databases.
NCT05423158
Home-based CR (HBCR) is an alternative to traditional CR programs that has comparable efficacy in improving morbidity/mortality and increases access to critical services. There is major potential to improve Veteran engagement in CR by combining digital coaching (d-Coaching) with existing VA-supported technologies. The investigator's theory-based intervention targets a critical component of successful CR engagement that is not available through traditional programs: virtual social support through a social network. In addition, the investigators propose to improve self-efficacy and self-regulation through interactive digital multi-media education, personalized feedback, and motivation so that Veterans can complete the prescribed HBCR program and maintain physical activity long-term. This RCT will evaluate the effects of HBCR alone (usual care) versus HBCR + d-Coaching, including a private group with direct messaging on the Connecteam mobile application and bimonthly engagement sessions via VA Video Connect. The investigators will randomly assign 150 Veterans from 2 HBCR programs to a 3-month intervention. The addition of d- Coaching to existing digital technologies will be operationalized by using a private social media group to provide social support, education, personalized feedback, and motivation. The investigators aim to determine the effect of the d-Coaching intervention on: a) the number of completed HBCR sessions over 3 months, b) functional capacity, c) physical activity, c) psychosocial outcomes, d) clinical outcomes, and e) social cognitive factors of self-efficacy, self-regulation, and perceived social support over 6 months. The investigators will also evaluate the extent to which self-efficacy, self-regulation, and perceived social support mediate the effect of the intervention on function and physical activity.
NCT04141605
The primary objective of this study is to collect real-world clinical performance data to assess the clinical outcomes of patients receiving heart transplants using donor hearts transported via the SherpaPak CTS System. These results will be compared to outcomes of retrospective patients whose hearts were transported with the previous standard method.

The main purpose of this study is to evaluate the efficacy and safety of retatrutide once weekly in participants with obesity and established cardiovascular disease (CVD). The study will last about 113 weeks.
NCT06212466
A prospective, multicenter, observational, single-arm trial to validate CardioFlux MCG's ability to diagnose myocardial ischemia caused by coronary microvascular dysfunction in patients with suspected ischemia and confirmed no obstructive coronary artery disease (suspected INOCA) by using diagnostic measures of coronary flow reserve (CFR) via invasive angiography as a reference standard for diagnosis.
NCT05602454
The purpose of this study is to evaluate how safe and effective a remote, digital intervention is that helps clinicians use and optimally adjust heart failure medications, compared to usual care medication use and adjustment, in participants with heart failure with reduced ejection fraction
NCT05428384
The investigation will enroll subjects who have been previously implanted with the CardioMEMS™ Pulmonary Artery Sensor. This clinical investigation is twofold; in the first phase (development phase) data collected will be used to complete development of an algorithm that can estimate cardiac output from CardioMEMS™ Heart Failure (HF) System readings. The second phase (validation phase) of this clinical investigation is intended to compare the Cardiac Output estimate from CardioMEMS HF System to Cardiac Output estimates from Cardiac Magnetic Resonance Imaging (reference standard).
NCT03252093
Coronary Artery Bypass Graft (CABG) is a surgical procedure known to be associated with cognitive impairment. Mechanisms of cognitive impairment are complex but may include insufficient oxygenation and inflammation due to exposure to the bypass circuit. Currently there are no approved therapeutics for the prevention or treatment of cognitive impairment in these patients. A small peptide, Angiotensin-(1-7) \[Ang-(1-7)\], is known to decrease inflammation in the brain in animal models. Early studies in humans have shown it to be safe. This peptide is naturally produced by the body and has anti-inflammatory and vasodilatory effects. Investigators believe that Ang-(1-7) may be able to help lower the risk of cognitive dysfunction in patients undergoing CABG. The goal of this project is to explore effects of the experimental peptide Angiotensin-(1-7) (Ang-(1-7) in patients undergoing an elective CABG surgery to determine its safety and efficacy to prevent cognitive dysfunction in patients undergoing CABG.
NCT07133984
STICOS will test the hypothesis that residual jeopardized myocardium, late gadolinium enhancement, and non-ischemic substrate after revascularization is associated with postoperative adverse cardiovascular events such as heart failure , readmission, or death. This study will look at whether certain heart tissue abnormalities seen on MRI scans can help predict serious health problems after heart procedures like stents or bypass surgery.
NCT05176756
This is a two-arm, randomized, controlled trial to evaluate the effectiveness of using a behaviorally designed gamification intervention with social support compared to an attention control group to increase physical activity during a 6-month intervention with a 3-month follow-up period. We will enroll 150 Black or Hispanic breast and prostate cancer survivors who are at an especially high risk for developing major CVD from two U.S. cancer centers: the University of Pennsylvania Health System and City of Hope National Medical Center. All participants will receive a wearable activity tracker (Fitbit) and will be enrolled in the Way to Health system, a research information technology platform at the University of Pennsylvania. Within the Way to Health platform, patients will set a goal to increase daily step count from baseline, and will then be randomized to gamification plus social support or to attention control. The study will evaluate the effect of the gamification intervention on daily physical activity (as measured by daily steps and moderate to vigorous physical activity), physical function, fatigue, and health-related quality of life.
