THis study is intended to provide contemporary data on the burden of disease in patients 1 to 3 years post-MI, including a description of patient characteristics, current treatment patterns, rate of major CV events, and healthcare resource utilization in a 'real world' patient population at high atherothrombotic risk.
NCT01369953
Since 2007, the cost of sequencing a diploid human genome has fallen dramatically, from approximately $70 million to $20,000. As affordable sequencing platforms become more widely available, the advancement of biomedical science will draw increasingly on whole genome sequencing research requiring large cohorts of diverse populations. Key policy, ethical and legal implications of these developments will need to be understood in order to promote the efficacy and effectiveness of genomic research going forward. An overall aim of this project is to obtain feedback on the informed consent process from some of the earliest particpants in studies using whole genome sequencing. A more specific goal is to characterize the salient personal and public references accessed by participants around the time of the informed consent process. By highlighting trends in participants views about study participation around the time of the initial informed consent process, we aim to advance the development of an ethically and socially relevant vocabulary with which to negotiate future terms of use for personal sequence data in genomic research. Participants will be asked to complete a one-time, semi-structured telephone interview lasting approximately 45 minutes in the period 2-8 weeks following their initial informed consent session at the NIH. They will be recruited from two NIH protocols employing whole genome sequencing for distinct purposes. They The ClinSeqTM Study is a large-scale medical sequencing project investigating the causal role of genetics in cardiovascular disease enrolling both symptomatic and healthy individuals. The Whole Genome Medical Sequencing for Gene Discovery Study (WGMS) enrolls children and adults for full sequencing with the aim of discovering the genetic etiology of rare conditions.
NCT01557543
Background: \- Bone marrow stromal stem cells (also known as mesenchymal stem cells) have been isolated and are found to make large amounts of growth factors. Because they make growth factors, these cells can help re-grow tissue and encourage repair of damaged tissue. Tests on damaged heart muscle suggest that injecting these cells directly into damaged heart muscle can improve heart function. Researchers want to give stem cells to people who are having open heart surgery to see if they can help to repair heart muscle damage. Objectives: \- To test the safety and effectiveness of bone marrow stromal stem cell injections given during heart surgery to treat heart muscle damage. Eligibility: \- Individuals at least 18 years of age who are scheduled to have open heart surgery for heart artery or vein blockages. Design: * Participants will be screened with a physical exam and medical history. Blood and urine samples will also be collected. * Participants will have bone marrow taken from both hip bones about 3 weeks before the heart surgery. * During the surgery, the stromal stem cells collected from the bone marrow will be given into the damaged portion of the heart muscle. The rest of the heart surgery will be performed according to standard procedures. * After the surgery, participants will be monitored for complications from the stromal stem cells. * Participants will have heart function tests to see if the stromal stem cell treatments were effective....
NCT01866592
VIP-E is a one-arm, open-label, 40-52 week extension study to continue or cross over subjects of the VIP study (# 814278) to active drug (adalimumab) to determine if there is sustained improvement in vascular inflammation, lipid metabolism, and inflammatory markers. VIP-E extends VIP study procedures for 40-52 weeks including questionnaires, physical exams, blood and urine samples, lab tests, one additional FDG-PET/CT scan, and adalimumab injections following FDA-approved psoriasis treatment regimen.
NCT01553058
The purpose of this study is to assess the effect of adalimumab (Humira), when compared to NB-UVB (narrow-band ultraviolet B) phototherapy or placebo (an inactive substance that may resemble an active substance but has no medical value) injection. The study will compare the effects of each on systemic inflammation and cardiovascular disease risk factors in subjects diagnosed with moderate to severe psoriasis. This study will look for systemic vascular inflammation in subjects with a test called FDG-PET/CT (Fluorodeoxyglucose-positron emission tomography/computed tomography). The study will also look for cardio metabolic (heart disease and metabolic factors such as diabetes) identifiers in the blood. A blood sample will be taken that will look for these markers identifying high cholesterol, cholesterol efflux function (the ability of cholesterol to move in the body), metabolic factors, and inflammation. This study will also assess the effect of adalimumab (Humira), when compared to NB-UVB phototherapy or placebo injection on psoriasis activity and severity. The study will also compare the safety of adalimumab (Humira) to NB-UVB phototherapy or placebo injection. This study will also evaluate subjects' reported outcomes through a questionnaire that will assess quality-of-life in subjects living with psoriasis.
NCT02996903
The "Prospective Multicenter Registry On RadiaTion Dose Estimates Of Cardiac CT AngIOgraphy IN Daily Practice in 2017" (PROTECTION-VI) study is a prospective registry and investigator-initiated initiative without third-party funding, which will collect and analyze the radiation dose exposure of Cardiac Computed Tomography Angiographic (CCTA) studies in current daily practice worldwide. Particularly, the study will assess the use of strategies for dose reduction during CCTA. A decade ago, the multicentre observational PROTECTION-I study has revealed that the dose-length-product of CCTA ranges between 568 - 1259 mGy x cm with a median of 885 mGy x cm. This corresponds to an estimated effective dose of approximately 12 mSv. Since then a variety of techniques have been developed and enhanced in order to reduce radiation exposure during CCTA. Recent studies demonstrated feasibility of dramatically reduced effective radiation doses during CCTA (0,1 - 0,3 mSv). This has been executed in small cohorts of patients at scientific expert centers. However, it remains unclear, if such low-level radiation dose exposure may be achieved in clinical routine and if diagnostic image quality is maintained. In order to analyze the magnitude of radiation dose exposure of CCTA in today's clinical practice and the current use of dose-saving techniques, we designed the PROTECTION-VI study. Eventually, this study may contribute to further improving radiation dose exposure for patients undergoing CCTA.
NCT01374555

NCT01901809
Heart Failure with preserved Ejection Fraction (HFPEF) accounts for 40-50% of all heart failure patients with a frequency of hospital admissions for acute decompensation and short and long term mortality similar to patients with heart failure with reduced ejection fraction (HFREF). Patients with HFPEF are often preload dependent and despite admission to the hospital for acute decompensated heart failure (ADHF), are typically difficult to diurese due to the development of acute kidney injury. No studies have been performed evaluating treatment strategies for these patients. The investigators hypothesize that changing the method of diuresis and/or the addition of low-dose dopamine for the treatment of ADHF in patients with HFPEF will reduce renal injury, resulting in a shorter length of stay, and decrease hospital readmissions over the ensuing year. This trial will randomize patients to either bolus or continuous infusion furosemide and then to either dopamine or no dopamine. The primary endpoint will be renal function at 72 hours as measured by change in Glomerular Filtration Rate (GFR). Secondary endpoints for readmission, functional capacity, quality of life, and amount of diuresis will also be collected.
NCT01440335
Background: \- Fenoterol has been used to treat asthma by opening up the airways in the lungs. It also increases the heart rate without significantly increasing blood pressure. This means that it may help improve heart function by boosting the heart's output. Researchers have developed a different form of the drug that may be given to individuals with heart trouble. This new form needs more testing. It is especially important to compare the new form with the original form of the drug used to treat asthma. Objectives: \- To compare how safe and effective two different forms of Fenoterol are in improving heart function. Eligibility: \- Healthy people between 21 and 60 years of age who have no history of heart disease. Design: * People will be screened with a medical history, physical exam, blood and urine tests, and heart function studies. * Those in the study will have two 36-hour inpatient study visits. At each visit, they will have a physical exam and blood and urine tests. They will fast overnight and then receive one of the two forms of Fenoterol first thing in the morning. They will not know whether they are getting the original or the modified form of the drug. After receiving the drug, they will provide frequent blood and urine samples for 24 hours. They will have a final exam before being discharged. * Those who take part in the study will have a followup visit 5 to 7 days after the end of each study visit. They will provide more blood and urine samples and have a physical exam.
NCT01953874
The aim of the study is to compare the effects of MV targeted ASV in addition to optimized medical therapy versus optimized medical therapy alone at 6 months in patients with acute decompensated HF. The study will also assess changes in functional parameters, biomarkers, quality of life (QOL), and sleep.
NCT02601560
This is a Phase 2a randomized, double-blind (subject/investigator blinded, MedImmune unblinded), placebo-controlled, dose-escalation study to evaluate the safety, PK/PD, and immunogenicity of single IV and SC MEDI6012 doses in adult subjects with stable CAD.
NCT02512835
Social determinants of health (e.g. the income, education, and environment of patients) may exert greater influence on health outcomes than traditional clinical factors (e.g. lab results, diagnoses, and family history). Calls for integrating primary care and public health are therefore increasing, but merging these domains of care is logistically difficult. Research is lacking on the incremental benefit of adding public health data at the practice level-- in improving either health outcomes or care delivery. This proof of concept pilot will merge data from electronic health records (EHRs) with community vital signs, a set of metrics that describes key community resources that affect health. The investigators will identify resource poor communities, or cold spots, based on four variables (education, poverty, life expectancy, and access to healthy foods) at the census tract level - referred to as a community vital sign. The hypothesis is that patients coming from cold spots are more likely to have worse health outcomes and that clinicians will deliver better care if they know a patient's community context and his/her specific social needs. This study will involve 12 primary care practices in Northern Virginia that care for more than 170,000 patients. Patient addresses will be geocoded for each practice and determine which patients reside in cold spots for each community vital sign. The variation for each community vital sign for each practice's patients will be calculated and a bivariate and regression analyses will be used to determine whether coming from a cold spot is associated with worse clinical quality metrics. 15 clinicians will be alerted when they see a patient from a cold spot, patients will complete a social needs survey, and clinicians will prospectively document through surveys whether such knowledge affects interpersonal interactions (such as time spent with patients and the use of clearer language) or clinical management (such as referrals to care coordination or community resources). By pragmatically integrating community vital signs into care, this innovative proposal will seek to understand which community data clinicians value, how these data might influence care, and how best to incorporate these data into clinical and population care.

All subjects will be screened according to the protocol inclusion and exclusion criteria and will be followed through hospital discharge.
NCT00115349
The purpose of this study is to determine whether left ventricular function improves more rapidly with deferoxamine (DFO) and deferiprone (L1) combination therapy than with DFO monotherapy in patients with thalassemia and decreased ejection fractions. Secondary aims include evaluating changes in myocardial iron burden using T2\* and estimating the relative incidence and severity of chelator-induced toxicity.
NCT00458276
Endothelin-1 is a powerful substance that may be involved in causing hemodynamic instability (problems related to unstable blood pressure) during and after open heart surgery. Tezosentan is an investigational intravenous drug that blocks the endothelin receptors. This clinical trial will assess the potential benefit of tezosentan compared with placebo in the treatment of patients undergoing open heart surgery with cardiopulmonary bypass (CPB). Treatment time is from the start of surgery up to 24 hours.
NCT01370564
This chronic, prospective, non-randomized feasibility study is designed to evaluate the Integrated Patient Care (IPC) concept in subjects who already have either a Medtronic Chronicle Implantable Hemodynamic Monitor (IHM) or Chronicle Implantable Cardioverter Defibrillator (ICD) device implanted, and are currently enrolled in the Chronicle Offers Management to Patients with Advanced Signs \& Symptoms of Heart Failure (COMPASS-HF) Extension Phase Study (IDE # G020304). The purpose of the study is to use daily cardiac filling pressures from the Chronicle device to provide timely medication adjustments (diuretics) to subjects.

NCT01890421
Participants being evaluated for suspected or known Coronary artery Disease (CAD) based on signs and/or symptoms, will be invited to participate in the study. The duration for a participant in the study may range from 2 days to 4-6 weeks. One to four visits to the study doctor will be required. This study will investigate the diagnostic results of gadobutrol-enhanced Cardiac Magnetic Resonance Imaging (CMRI) images regarding the detection (sensitivity) and exclusion (specificity) of coronary artery disease utilizing a uniform image acquisition software. The CMR images will be tested either against the results from routine clinical Coronary Angiography (CA) or those from Computed Tomography Angiography (CTA), which is used as the standard of reference. The CA/CTA may have been performed up to 4 weeks prior to enrollment or be scheduled up to 4/6 weeks after the study. CMRI and CA/CTA images will be collected for an independent image review (blinded read).
