NCT00997503
The TAXUS Libertē Post-Approval Study is an FDA-mandated prospective, multi-center study designed to collect real-world safety and clinical outcomes in approximately 4,200 patients receiving one or more TAXUS Liberté Paclitaxel-Eluting Stents and prasugrel as part of a dual antiplatelet therapy (DAPT) drug regimen. This study will also contribute patient data to an FDA-requested and industry-sponsored research study that will evaluate the optimal duration of dual antiplatelet therapy (DAPT Study).
NCT00484315
The purpose of the TAXUS PERSEUS Workhorse trial is to evaluate the safety and efficacy of the next-generation Boston Scientific TAXUS paclitaxel-eluting coronary stent system (TAXUS® ElementTM) for the treatment of de novo atherosclerotic lesions of up to 28 mm in length in native coronary arteries of 2.75 mm to 4.0 mm diameter.
NCT01643590
This is a randomized, double-blind, placebo controlled Phase II study is designed to assess the safety and efficacy of using JVS-100 to treat heart failure.
NCT00795873
Post approval study measuring safety outcomes on the Ovatio CRT-D and SITUS OTW LV lead over 5 years.
NCT00277524
The purpose of the OMNI study is to characterize therapy and diagnostic utilization in study participants implanted with study devices and to describe Implantable Cardioverter Defibrillator(ICD)therapy utilization for life threatening arrhythmias in primary and secondary prevention study participants. This study will assess therapies in Medtronic pacemaker, defibrillator, and cardiac resynchronization therapy devices. The first therapy is for reducing unnecessary pacing in pacemaker patients. The second therapy provides pacing therapy in an attempt to stop fast or life threatening ventricular arrhythmias in lieu of delivering a defibrillation shock. The third therapy is a diagnostic measurement of a patient's fluid status and provides the physician information on the patient's heart failure status. The study will also assess the time to a patient's first defibrillation shock and will verify that the shock was for a fast or life threatening ventricular rhythm.
NCT01523392
The purpose of this study is to assess the pharmacodynamic effect of ticagrelor in African American patients with stable coronary artery disease.
NCT01071967
Care coordination, disease management, geriatric care management, and preventive programs for chronically ill older adults vary in design and their impact on long-term health outcomes is not well established. This study investigates whether a community-based nursing intervention improves longevity and impact on cardiovascular risk factors in this population. The results reflect the impact of one of the study sites (Health Quality Partners) selected by the Centers for Medicare and Medicaid Services (CMS) to participate in the Medicare Coordinated Care Demonstration, a national demonstration designed to identify promising models of care coordination for chronically ill older adults. The study began in April 2002.
NCT01440517
The purpose of this study is to evaluate the results of 99mTc maraciclatide scintigraphy in diabetic subjects with HFPEF. A maximum of 20 subjects with Diabetes Mellitus (DM) and Heart Failure With Preserved Left Ventricular Ejection Fraction (HFPEF) will be enrolled and imaged with 99mTc maraciclatide. In addition, a maximum of 10 subjects with DM and diastolic dysfunction but no diagnosis of heart failure (HF) will be enrolled and imaged with 99mTc-maraciclatide.
NCT01605292
Radial artery access for cardiac catheterization can require multiple attempts. Multiple attempts increase the time required, patient discomfort, and the risk of arterial spasm. Ultrasound guidance has been shown in other studies to reduce the number of attempts and complications in central venous and femoral artery access. This study will test if the addition of ultrasound guidance reduces the number of attempts and time required to access the radial artery.
NCT01272453
This is a prospective, controlled observational trial of patients undergoing clinically indicated cardiothoracic computed tomography (CT), including pulmonary or aortic angiography and coronary CT angiography (CCTA).
NCT00057356
This is a randomized, double-blind, placebo-controlled, dose ranging pilot study to examine the effects of conivaptan in patients with acute decompensated heart failure.
NCT01425359
This study will evaluate the effect of ranolazine compared to placebo on the average weekly angina frequency in subjects with chronic stable angina and coronary artery disease (CAD) who have a history of type 2 diabetes mellitus (T2DM), and whether ranolazine can reduce the frequency of angina (chest pain) attacks, compared to a placebo. Subjects will be asked to record their daily angina episodes in a diary at the end of each study day. Ranolazine is approved for the treatment of chronic angina, and is not approved for the treatment of T2DM.
NCT01960218
To determine whether, and if so, which gas exchange parameters measured on the Shape-HF Cardiopulmonary Exercise Testing System predict 30 and 180 day re-hospitalization in subjects discharged from hospitalization for an episode of acute decompensated heart failure.
NCT01259297
This study was planned to provide new information regarding the role of aliskiren (with or without additional therapy with a diuretic or a Calcium channel blockers (CCB)) in elderly individuals (≥ 65 years) with systolic blood pressure (SBP) 130 to 159 mmHg, in preventing major cardiovascular (CV) events and on global measures of physical, executive and cognitive function.
NCT00054847
VA patients with coronary artery disease and who have agreed to undergo coronary artery bypass graft surgery would be randomized to receive either radial artery or saphenous vein to the study vessel. The primary outcome variable is graft patency at one year.
NCT02045043
Arrhythmias remain a major health problem, causing at least 250,000 deaths annually in the United States. Pharmacological treatments often do more harm than good, and device therapies are limited by high cost and effects on quality of life. Ion channel mutations cause rare inherited arrhythmopathies, but account for only a small fraction of patients with life- threatening arrhythmias and sudden death. Most arrhythmias occur during myocardial ischemia, following myocardial infarction, and in patients with poor left ventricular (LV) function of any etiology. Aside from ejection fraction (EF), few clinically useful indicators to stratify the risk of sudden death have been identified. The role of subtle difference in ion channel expression and/or structure in predisposing patients to arrhythmias and modulating the risk of sudden death is unknown. In this study, we are prospectively testing whether polymorphisms in ion channels and ion channel modifying genes are associated with arrhythmias in a population with internal cardioverter-defibrillators (ICDs) and poor LV function. We will test the hypothesis that functional polymorphisms in the coding sequences and promoter regions of cardiac genes (e.g. ion channels, beta-adrenergic receptors) predispose individuals to arrhythmias and /or heart failure progression. We hope to identify genetic predictors for the common forms of sudden cardiac death. This would allow the identification of a subpopulation of heart failure patients that would benefit most from ICD placement.
NCT00763867
Diastolic heart failure (DHF), which affects older individuals and women at a disproportionate rate, is a condition that can lead to shortness of breath and fluid build-up in the lungs. This study will evaluate the effectiveness of the medication sildenafil at improving exercise ability and health outcomes in people with DHF.
NCT02167789

NCT00661206
The purpose of this study is to determine whether a 6 month duration of clopidogrel therapy after DES implantation is not inferior to that of a 12 month therapy.
NCT01299324
The primary objective of this feasibility study is to provide clinical data to demonstrate the safety and activity of a concentrate of nucleated cells from bone marrow aspirate (BMAC) produced with the Harvest Bone Marrow Aspirate Concentrate System for treating patients diagnosed with congestive heart failure (CHF).
