The Physiologic Pacing Registry is a prospective, observational, multi-center registry performed to gain a broader understanding of 1) physiologic pacing implant and follow-up workflows, including pacing and sensing measurements and 2) the clinical utility in creating a 3-dimensional electro-anatomical map of cardiac structures prior to physiologic pacing device implants based on the clinical site's routine care.
NCT03016754
This study is designed as a multi-center prospective observational study of newly diagnosed Heart Failure (HF) patients to test the hypothesis that additional Ejection Fraction (EF) recovery occurs between 90 and 180 days as Guideline Directed Medical Therapy (GDMT) is achieved. Although the study doesn't start until day 90, all eligible, consenting patients will be entered into a registry at the start of wearable cardioverter defibrillator (WCD) use. The pre-study registry will allow us to collect early (90 day) outcomes and data in those patients who are likely to be eligible for the study at day 90, or are eligible, but refuse the study at day 90.
NCT04096040

NCT02991534
Cardiovascular (CV) disease is the number one cause of death in American women, and all adult women are potentially at risk for CV disease. There are clear gender differences in the control of CV risk factors such as lipids, blood pressure, and intermediate diabetes outcomes nationally and within the VA, with women Veterans often at higher CV risk than their male counterparts. The combination of disparities and gender-specific CV risk factors suggest an urgent need for CV risk factor management in women Veterans. As one project in the Enhancing Mental and Physical health of Women through Engagement and Retention (EMPOWER) QUERI, the objectives of "Facilitating Cardiovascular Risk Screening and Risk Reduction in Women Veterans" are to implement and evaluate a CV risk reduction toolkit (CV toolkit) designed to increase identification of CV risk among Women Veterans, enhance patient/provider communication about their risk, and increase Women Veterans' engagement and retention in relevant health services including referrals to key health programs (e.g., MOVE!, dieticians, health coaches, and CV specialists as needed). The initial CV Toolkit includes four components: (1) Patient education/activation tools including educational materials and a patient CV self-screener to help make CV risk discussion a priority for women before they enter the exam room; (2) A CV risk assessment computerized template to systematically capture CV disease risk factor history and data from the medical record and then facilitate referrals to Gateway to Healthy Living program and other CV risk reduction services/programs; (3) Provider information and education programs as well as referral tools to internal services; and (4) The Gateway to Healthy Living, a facilitated goal-setting group tailored for women Veterans. The goal is to implement the CV Toolkit at four VA facilities with comprehensive women's health clinics. The implementation of the CV Toolkit will be evaluated using a non-randomized stepped wedge design and will apply the evidence-based Replicating Effective Programs (REP) implementation strategy. For the nonrandomized stepped wedge design, each phase represents when one site moved from inactive to active implementation. It was pre-specified for the non-randomized design to evaluate the outcomes as the odds ratio of active intervention versus inactive for the overall study period and not by individual site/phase. This is a function of the use of the non-randomized design. Since the order of sites being introduced into the active intervention is not random, probabilistically the individual site results are not as meaningful here as they would be in a randomized stepped wedge design. Also, mixed methods implementation evaluations will focus on investigating primary implementation outcomes of adoption, acceptability, feasibility, and reach. Multilevel stakeholder engagement will be prioritized. Program-wide organizational-, provider-, and patient-level measures and tools will be utilized to enhance synergy, productivity, impact and facilitate spread.

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.

NCT04343209
This study is being conducted to provide access to and collect test data for an established nuclear medicine diagnostic imaging test called Positron Emission Tomography (PET), using a specific radioactive drug called Ammonia N-13 (Ammonia), referred to simply as an Ammonia PET scan, which is used to visualize the blood flow through the blood vessels and into the heart muscle in order to identify areas of restricted blood flow within the heart. The scanner used in this study may be a stand-alone PET scanner or a PET/CT scanner, which combines the PET scanner and a Computed Tomography (CT) scanner into a single device. Unless otherwise stated in this consent form, the term PET will be used to refer to both stand-alone PET and PET/CT scanners. While physicians have used the Ammonia PET test for many years to visualize (image) the blood flow into the heart muscle (perfusion), it is now possible to also measure the flow of blood into the heart muscle. Research studies have demonstrated clinical value in reviewing the measured blood flow values in addition to reviewing the perfusion images of blood flow into the heart muscle. Therefore, this study will establish a database of a large number of Ammonia PET measured blood flow values to serve as a future reference.
