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.
NCT00006181
Promoting Healthy Lifestyles: Alternative Models' Effects (PHLAME) is a research study to evaluate and compare two ways to promote healthy behaviors, (regular physical activity, less than 30% calories from fat, 5 or more servings of fruits plus vegetables each day and maintain a healthy weight). Unhealthy nutrition practices and sedentary (inactive) lifestyles are the two most common harmful behaviors in the United States. Our two health promotion methods are 1) a team-based approach and 2) a one-on-one approach involving meetings with a health counselor. A third group only receives the same evaluation and their results and is the control group. Study participants are firefighters from 36 fire stations in Oregon and Washington. The goals of the study are increased physical activity and fitness, improved nutrition, and improved energy balance (reduced body fat). Changes in these factors can help lower risks for heart disease, some types of cancer, diabetes, hypertension and musculoskeletal injuries. Results from PHLAME will provide information on how best to help adults achieve and maintain healthy lifestyles.
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.

The Corox OTW Steroid LV Lead is capable of providing permanent pacing therapy to the left ventricle in a CRT-D system. The following are the specific objectives to be evaluated during this post-approval registry: * Long-term effectiveness of the COROX OTW Steroid in providing biventricular pacing * Safety of the COROX OTW Steroid LV pacing lead
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.
NCT00957034
Heart failure (HF) is a complex condition resulting from structural or functional heart diseases that impair the ability of the heart to fill with or pump out blood. The main manifestations of HF are shortness of breath and tiredness which may limit the ability to exercise or perform simple daily physical activities such as walking. Heart disease leading to HF is associated with reduced muscle mass and reduced strength and low blood levels of testosterone; a hormone normally produced by the human (male and female) body. Recent studies have shown improvements of symptoms and ability to exercise in patients with heart failure receiving testosterone. This is a placebo controlled study to determine the efficacy and safety of low dose testosterone (300 and 450 microgram/day) delivered by a transdermal system (patch) in women with significant HF.
NCT00863707
This study is intended to assess the safety and tolerance of regadenoson in subjects with renal impairment.

NCT00206856
To determine the clinical utility of using the Triage® BNP Test to guide therapy in outpatients with heart failure
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.
NCT00180466
