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.
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.
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.
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.
NCT00201110
The purpose of this study is to test a measurement tool and a new training intervention for problem solving in self-management of high cardiovascular disease (CVD) risk in African Americans with type 2 diabetes.
NCT01086800
This study examines the role of sleep apnea treatment in improving cardiovascular biomarkers.
NCT01107912
The 5-milligram (mg) maintenance dose (MD) of prasugrel in very elderly patients with coronary artery disease produces a pharmacodynamic response within the same therapeutic range as 10-mg MD in non-elderly patients.
NCT00233311
The purpose of this research study is to determine whether eating a fast food meal (high in saturated fat) will result in greater increases in inflammatory markers than eating a meal with low levels of saturated fat and higher levels of mono-unsaturated fat. This study is a first step in learning about how dietary fat intake can directly impact risk factors for heart disease, diabetes and obesity.
NCT00291551
This is a limited safety and feasibility study to evaluate the PVSS Introducer and Paracor Ventricular Support System when used to treat patients with heart failure. The implant, which is loaded onto the delivery system, is placed over the epicardial surface of the right and left ventricles. No formal hypothesis testing will be performed; descriptive statistics will be used to summarize patient outcomes. The results of the study will be used to guide the design and sample size estimation of future studies.
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.
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.
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.
NCT00863707
This study is intended to assess the safety and tolerance of regadenoson in subjects with renal impairment.
NCT00795873
Post approval study measuring safety outcomes on the Ovatio CRT-D and SITUS OTW LV lead over 5 years.
NCT01539629
This 3rd phase of the ELEVATE study. The study is collecting data from an implanted CRT-D device to evaluate a new feature for future heart failure devices.
NCT01229137
Assessment of sensor parameter in patients with heart failure.
NCT00206856
To determine the clinical utility of using the Triage® BNP Test to guide therapy in outpatients with heart failure
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.).
NCT01107925
The 5-milligram (mg) dose of prasugrel in low body weight (LBW) patients with coronary artery disease produces a pharmacodynamic response within the same therapeutic range as 10-mg dose in higher body weight (HBW) patients.
NCT01171404
The aim of this international study is to describe the short- and long-term (i.e. up to 2 years following the index event) antithrombotic management patterns (AMPs) in patients hospitalized for acute coronary syndromes (ST segment elevation myocardial infarction (STEMI), Non-ST-Segment Elevation Acute Coronary Syndrome (NSTE-ACS)), and to document the impact of AMPs in clinical outcomes, economic variables and quality of life in a 'real-life' setting and to compare these between sites, countries and regions.
