NCT00807040
People with coronary artery disease (CAD) or people who have had a heart attack may develop a leak in the mitral valve of their heart and may therefore need to undergo surgery to fix the valve. The best way to fix the mitral valve remains undetermined. This study will evaluate whether it is better for people with severe mitral valve leakage to undergo a mitral valve replacement procedure or a mitral valve repair procedure.
NCT01076348
Safety and effectiveness will be summarized for the model 4965 lead. This study was conducted within Medtronic's System Longevity Study (SLS).
NCT00418314
The objective of this study is to demonstrate that frequent atrio-ventricular (AV/PV) and inter-ventricular (V-V) delay optimization using QuickOpt in patients with cardiac resynchronization therapy device results in improved clinical response over standard of care (i.e. empiric programming or one-time optimization using any non-intracardiac electrogram optimization methods).
NCT00303979
The purpose of this study is to characterize current management of patients with either heart failure or prior myocardial infarction and left ventricular dysfunction and to assess the effect of education, specific clinical guidelines, reminder systems, comprehensive disease state management tools, benchmarked quality reports, and academic detailing on the use of evidence-based heart failure therapies in cardiology practices. This study is a quality improvement initiative that is being conducted through review of patient records.
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.
NCT00883857
The purpose of this study is to evaluate a new monitor that measures cardiac output (amount of blood pumped by the heart). The system that is being tested in this study, called Endotracheal Cardiac Output Monitor (ECOM), uses electricity (impedance cardiography) to measure cardiac output and is not harmful to the patient. This study will test the accuracy and efficacy of the ECOM system in anesthetized and sedated patients who, in the normal course of clinical care in the OR or ICU, are having cardiac output measured. The investigators propose that unlike the standard system for cardiac output measurement, the ConMed ECOM System should result in a simplified, inexpensive, continuous, less-invasive, and accurate method of measuring cardiac output. Such a technique could allow the rapid diagnosis of instability in the cardiovascular system for critically ill patients.
NCT00858845
People with heart failure often have weakness in their leg muscles. This study will determine whether the leg weakness is due to very high adrenaline levels and whether the medication clonidine can improve leg weakness.
NCT00916929
To demonstrate the safety and effectiveness of the Impedance Monitoring Feature in St Jude Medical cardiac devices.
NCT01786993
This IDE study is a prospective, randomized, double-blind, multi-center clinical study to evaluate the safety and efficacy of patient treatment with MPP compared to patient treatment with standard BiV pacing at 9 months. The study will be conducted at a maximum of 50 investigational centers located in the United States. A maximum of 506 subjects implanted with the Quadripolar cardiac resynchronization therapy device (CRT-D) system will be enrolled in the study.
NCT00500617
The PREDICT study is to develop and validate a diagnostic blood ASGES (age, sex, gene expression score) or Corus CAD for atherosclerotic coronary artery disease (CAD). The Corus CAD (Age/Sex/Gene Expression score - ASGES) will use quantitative real-time PCR (RT-PCR) to quantify the expression of multiple genes from circulating peripheral blood cells to assess the presence of clinically significant CAD in a patient.
NCT02548455
The primary intent of this study is to assess the safety of the model 1457Q Quartet LV lead at 3 months in a patient population indicated for cardiac resynchronization therapy.
NCT00927784
Left ventricular assist devices (LVADs) are one treatment option for people with congestive heart failure. This study will evaluate the safety of injecting mesenchymal precursor cells (MPCs) into the heart during LVAD implantation surgery and examine if injecting MPCs into the heart is effective at improving heart function.
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.
NCT01032629
The study will assess canagliflozin (JNJ-28431754) in the treatment of patients with type 2 diabetes mellitus (T2DM) with regard to cardiovascular (CV) risk for major adverse cardiac events (MACE). Other objectives include evaluating the overall safety, tolerability, and effectiveness of canagliflozin. The data from this study will be combined with the data from CANVAS-R study (Study of the Effects of Canagliflozin on Renal Endpoints in Adult Subjects with T2DM, NCT01989754) in a pre-specified integrated analysis of CV safety outcomes to satisfy US FDA post-marketing requirements for canagliflozin.
NCT01993862
The purpose of this study is to determine whether it is safe to send patients home from the hospital on the same day following an implantable cardioverter defibrillator (ICD) implant.
NCT02145481
The objective of the DeQCAD study is to measure the quality of the decision-making process for patients with coronary artery disease (CAD) and Acute Coronary Syndrome (ACS) who are making treatment decisions. In particular, this study is seeking to answer: a) How informed are patients about their treatment choices, b) are patients participating in the decision-making process as much as they would like to, and c) do the treatment decisions made match patients' preferences?
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.
NCT01826019
The overall objective of the HOPE-4 Phases (HT and CVD) is to develop, implement and evaluate an evidence-based, contextually appropriate programme for cardiovascular disease (CVD) risk assessment, treatment and control involving: (1) simplified algorithms implemented by non-physician health workers (NPHW) and supported by e-health technologies (tablets programmed with decision and counselling support software); (2) initiation of evidence-based cardiovascular (CV) medications and (3) treatment supporters to optimize long-term medication and lifestyle adherence.
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
