NCT00206856
To determine the clinical utility of using the Triage® BNP Test to guide therapy in outpatients with heart failure
NCT00307047
The purpose of the SPIRIT IV Clinical Trial is to continue to evaluate the safety and efficacy of the XIENCE V® Everolimus Eluting Coronary Stent System (XIENCE V®). The XIENCE V® arm will be compared to an active control, represented by the FDA-approved TAXUS® EXPRESS2™ Paclitaxel-Eluting Coronary Stent System (TAXUS®), commercially available from Boston Scientific. TAXUS® EXPRESS2™ Paclitaxel Eluting Coronary Stent System is manufactured by Boston Scientific.
NCT00795873
Post approval study measuring safety outcomes on the Ovatio CRT-D and SITUS OTW LV lead over 5 years.
NCT01031680
This study is carried out to assess whether dapagliflozin lowers blood glucose, body weight and blood pressure, when added to patients existing medications and how it compares with their usual treatment without added dapagliflozin. Safety data will be collected and analysed to confirm that treatment with dapagliflozin is safe and well tolerated in patients who have diabetes, cardiovascular disease and hypertension.
NCT00990327
The purpose of this study is to see whether apadenoson is as effective as adenosine when used as a pharmacological stress agent in myocardial SPECT-Imaging to detect defects in the supply of blood to the heart muscle (myocardial perfusion defects). The study will also look at whether apadenoson is better tolerated than adenosine when used in SPECT-MPI.
NCT00032643
Congestive heart failure (CHF) affects 4-5 million Americans, and its prevalence is predicted to increase over the next few decades. Thyroid hormone has unique actions which make it a novel and potentially useful agent for treatment of CHF. Due to possible adverse affects of thyroid hormone, there is interest in developing analogs with fewer undesirable side effects. 3,5- diiodothyropropionic acid (DITPA) has been shown to improve diastolic function in both animal models and a recently completed double-blind placebo controlled trial in 19 humans. The goal of the proposed Phase II study is to show safety and demonstrate a medication of efficacy of DITPA needed in patients with CHF. This study is a prerequisite for a larger Phase III trial which would determine whether mortality is improved with DITPA. To better define the appropriate doses, prior to the Phase II study we will conduct an initial pharmacokinetic study.
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.
NCT00282711
The purpose of this study is to compare two types of exercise stress testing to find the best method for detecting heart disease in women.
NCT00272805
The purpose of this study is to compare dosing compliance between study patients taking controlled release carvedilol once a day, and study patients taking immediate release carvedilol (Coreg) twice a day.
NCT00047437
The purpose of this study is to determine the long-term safety and effectiveness of exercise training for individuals with congestive heart failure (CHF).
NCT00354159
The purpose of this clinical research study is to evaluate the safety and effectiveness of the investigational implantable hemodynamic monitor (IHM), and of the IHM in combination with an implantable cardioverter defibrillator (ICD). The investigational IHM has the ability to record and report the force with which the heart pumps blood (heart pressures). When combined with the ICD, the device has the additional ability to send a strong electrical impulse, or shock, to the heart when it detects dangerously fast heartbeats to return it to a normal rhythm. The IHM and IHM/ICD are implanted surgically just under the skin in the upper chest area. This study will also determine how doctors use the information related to heart pressures in the management of heart failure.
NCT00990964
The purpose of the study is to assess lead implant success and complication rate using the Medtronic Attain Family of left-heart leads and delivery catheters.
NCT00371709
TAXUS ATLAS is a global, multi-center, single-arm, non-inferiority trial comparing results from patients treated with the TAXUS Liberté stent to an historical TAXUS Express control. The control group is a case-matched, blended population of TAXUS Express patients from the TAXUS IV and TAXUS V de novo clinical trials. The objective of the study is to evaluate clinical outcomes of TAXUS Liberté-SR stent in de novo lesions and to assess the non-inferiority of TAXUS Liberté versus TAXUS Express. The TAXUS Liberté-SR stent is hypothesized to have comparable safety and efficacy to the TAXUS Express stent.
NCT00371423
TAXUS ATLAS Direct Stent is a global, multi-center, single-arm, noninferiority trial comparing results from patients in whom the TAXUS Liberté stent was directly implanted (direct stenting) versus results from patients in whom implantation with the TAXUS Liberté stent was preceded by balloon angioplasty (pre-dilatation). The Control group consists of patients in the main TAXUS ATLAS trial, in which pre-dilatation was mandatory. The primary objective is to compare outcomes of direct stenting with balloon catheter pre-dilatation. The primary hypothesis is that late outcomes with direct stenting of the TAXUS™ Liberté Paclitaxel-Eluting Coronary Stent System will be non-inferior to conventional implantation with balloon catheter pre-dilatation
NCT00271154
Heart failure is a progressive disease that decreases the pumping action of the heart. This may cause a backup of fluid in the heart and may result in heart beat changes. When there are changes in the heart beat sometimes an implantable heart device is used to control the rate and rhythm of the heart beat. The purpose of the REVERSE clinical trial is to determine whether pacing in both the left and right ventricles using Cardiac Resynchronization Therapy (CRT) can help slow the progression of heart failure in people who have mild or previous symptoms and poor heart pumping function. This kind of therapy has previously been shown to reduce symptoms and improve exercise capacity in people with more advanced forms of heart failure.
NCT00863707
This study is intended to assess the safety and tolerance of regadenoson in subjects with renal impairment.
NCT00132886
This study will look at how a single dose of study medication (tolvaptan) versus an inactive sugar pill (placebo) effect pressures in the heart in patients with congestive heart failure. Higher than normal pressures can be related to symptoms of heart failure (shortness of breath, fatigue, etc.).
NCT01229137
Assessment of sensor parameter in patients with heart failure.
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.
NCT00812552
Multicenter, case-control study, to collect data regarding incidences of late and very late drug-eluting stent thrombosis with the aim of identifying trends and possible correlates of stent thrombosis.
