NCT02595814
The clinical characteristics, initial presentation, management, and outcomes of patients hospitalized with new-onset (first diagnosis) heart failure (HF) or decompensation of chronic HF are poorly understood worldwide. REPORT-HF is a global, prospective, and observational HF disease registry designed to characterize patient trajectories longitudinally during and following an index hospitalization for acute HF.
NCT00088179
During a heart bypass procedure, a substance called "complement" is activated by the body. This "complement activation" causes an inflammatory response that can lead to side affects such as chest pain, heart attacks, stroke, heart failure, or death. The purpose of this study is to find out if the study drug (pexelizumab), that blocks "complement activation," can reduce such side effects and be given safely to patients requiring the bypass procedure with the use of the heart-lung machine.
NCT00683696
The EchoCRT trial evaluates the effects of Cardiac Resynchronization Therapy (CRT) on mortality and morbidity of subjects with heart failure due to left ventricular systolic dysfunction, already receiving optimized HF medication, with a narrow QRS width (\< 130 ms) and echocardiographic evidence of ventricular dyssynchrony.
NCT00064753
The purpose of this randomized clinical trial is to determine if lowering homocysteine levels in renal transplant recipients with a multivitamin will reduce the occurrence of cardiovascular disease outcomes.
NCT00378950
Heart failure (HF) affects 5 million people in the United States. Health literacy, which is the ability to read and comprehend important medical information, plays an important role in the health of individuals with HF. This study will evaluate the effectiveness of an educational program developed for various levels of health literacy at improving medical outcomes and quality of life in individuals with HF.
NCT00048308
During a heart bypass procedure, a substance called "complement" is released by the body. This complement causes inflammation, which can lead to side effects such as chest pain, heart attacks, heart failure, or impairment of memory, language and motor skills. The purpose of this study is to find out if the study drug (pexelizumab), which blocks complement release, can reduce such side effects and be taken safely.
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.
NCT00079963
This randomized placebo-controlled trial will test whether supplementing with vitamins C and E can lower markers of inflammation and oxidative stress in healthy adults. We will examine whether one antioxidant vitamin is more effective than another, and whether gender or body fat influence the treatment effects. We will also determine whether gender, body fat, or menopausal status are associated with baseline concentrations of inflammation and oxidative stress markers.
NCT00116428
This trial compares the safety and effectiveness of catheter ablation for PAF with antiarrhythmic drug therapy. The investigational catheter being studied is the NAVISTAR® THERMOCOOL® irrigated-tip catheter. At the time of this study, the NAVISTAR® THERMOCOOL® catheter was FDA-approved for commercial distribution in the U.S. for treating patients with Type I atrial flutter and drug refractory monomorphic ventricular tachycardia post myocardial infarction. The catheter was approved for use in Europe for endocardial ablation for treating cardiac arrhythmias.
NCT03126994
This is a prospective, single-center, non-randomized validation study being conducted under a non-significant risk study design with the primary aim to evaluate PWV, PR, and BW accuracy in a sample of subjects representative of the US general adult population. The primary study objective is to demonstrate equivalency when measuring: Pulse Wave Velocity (PWV) and Pulse Rate (PR) between the PhysioWave Cardiovascular Analyzer (CA) and AtCor Medical SphygmoCor® XCEL PWA \& PWV (XCEL), and Body Weight (BW) between the CA and the Detecto Solo Digital Healthcare Scale (Detecto).
NCT03207646
This study evaluates a smartphone-based cardiac rehabilitation program in adults with coronary artery disease. Half of patients will participate in a smartphone-based cardiac rehabilitation program while the other half will receive standard-of-care.
NCT01435031
A prospective, multi-center, single-arm study to establish the safety and effectiveness of the XIENCE V® Everolimus Eluting Coronary Stent, XIENCE nano™ Everolimus Eluting Coronary Stent, XIENCE PRIME™ LL Everolimus Eluting Coronary Stent, HT PROGRESS and HT PILOT Coronary Guide Wires, and MINI-TREK Coronary Dilatation Catheter in patients undergoing elective percutaneous revascularization of native chronic total coronary occlusions
NCT02302612
Cardiovascular disease (CVD) is the leading cause of death in the U.S. Efforts to improve CVD risk factors often fall short in complex patients with multiple co-morbid conditions, a growing, expensive, and high-risk segment of the U.S. population. The investigators are testing a multi-component behavioral intervention designed to help complex patients with CVD and other concurrent chronic conditions to become more effective agents of their own care.
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.
NCT02638129
The purpose of this study is to evaluate cardiovascular (CV) safety of naltrexone hydrochloride (HCl) and bupropion HCl extended release combination (NB) compared with placebo and rule out excess risk of major adverse cardiovascular events (MACE) when given in combination with standard of care in overweight and obese participants with documented history of CV disease.
NCT01866904
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.
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.
NCT02635477
A multicenter prospective randomized clinical trial testing the hypothesis that a patient-centered actigraphy intervention will result in increased physical activity for frail older adults increase during the critical first 30 days after a cardiovascular hospitalization.
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.
NCT00554671
