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.
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.

NCT00114972
The SYNTAX trial is designed to determine the best treatment for patients with complex coronary disease (blocked or narrowed arteries in both the right and left sides of the heart) by randomizing patients to receive either percutaneous coronary intervention (PCI) with polymer-based paclitaxel-eluting TAXUS stents or to coronary artery bypass surgery (CABG).
NCT00557921
The purpose of the COGENT-1 clinical trial is to determine whether CGT-2168 (clopidogrel and omeprazole) compared to clopidogrel is safe and effective in reducing the incidence of gastrointestinal bleeding and symptomatic ulcer disease, in the setting of concomitant aspirin therapy. Antiplatelet therapy is an essential element of care for patients with atherothrombotic disease. Bleeding is a fundamental adverse effect of all antiplatelet drugs including aspirin, clopidogrel and dual antiplatelet regimens. The gastrointestinal tract is the most common site of bleeding related to antiplatelet therapy, typically in connection with peptic ulcer disease. Recently published studies suggest the use of clopidogrel carries a gastrointestinal bleeding risk similar to that of aspirin or non-aspirin non-steroidal anti-inflammatory drugs. Patients taking any two of these drugs (clopidogrel, aspirin and/or non-aspirin NSAIDs) are exposed to an even higher risk of bleeding and ulcer disease. Cogentus Pharmaceuticals is launching phase 3 trials of a novel combination product, CGT-2168, which has the potential to significantly reduce this problem and increase patient safety. CGT-2168 combines a standard dosage of clopidogrel and a gastroprotectant (omeprazole) in a once-daily pill that may reduce the likelihood of adverse gastrointestinal events.
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.
NCT00455546
The study will be conducted at up to 80 centers worldwide and will be a double-blind randomized parallel group placebo controlled study among subjects with stable coronary artery disease (CAD). Subjects will be randomized to receive either placebo tablets or one of 4 orally active doses of A-002. The duration of study drug therapy will be 8 weeks.
NCT00584896
The purpose of this study is to determine if the use of PB127 with cardiac ultrasound assists in the diagnosis or exclusion of coronary artery disease.
NCT00584714
The purpose of this study is to collect longer term follow-up information concerning health and survival on selected patients who received PB127 for injectable suspension in the pivotal trial (127-014).
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.
NCT00269230
People who have abnormal heart beats, or whose heart does not beat on its own, may need an electronic device called a pacemaker or a defibrillator. Furthermore, people whose hearts have a reduced pumping ability may need a device are called cardiac resynchronization therapy (CRT) device. A CRT device is implanted surgically just under the skin in the upper chest area. This device then helps the heart beat at a regular rhythm by sending electrical signals (pacing) directly to the heart tissue through flexible wires called leads. The device may also be able to stop the heart from beating too fast. Three leads are implanted into the chambers of your heart. Two of the leads will be placed on the right side of your heart. The third lead is placed on the left side of your heart and is the lead being studied. The purpose of this study is to evaluate the safety and efficacy of the Attain StarFixTM Model 4195 Left Ventricular (LV) Lead. This particular model lead has special characteristics that may help to better keep it in position once it is implanted into the left ventricle. It is also "steroid-eluting" which means that over time it slowly releases a small amount of medication into the heart tissue to help prevent too much swelling around the area it is implanted.
NCT00528411
The purpose of this study is to see how Ticagrelor, a new oral reversible anti-platelet medication, affects platelets. Anti-platelet agents are medications that block the formation of blood clots by preventing the clumping of platelets. Blood clots prevent us from bleeding, but when they form inside the arteries their formation is linked to a risk of medical problems such as heart attack and stroke. This study investigated how long it takes for Ticagrelor to begin working and how long it takes for it to stop working after the last dose of drug. Ticagrelor will be compared to clopidogrel, an established anti-platelet treatment for preventing blood clots, and placebo plus Aspirin.
NCT00839007
The primary objective of the study is to assess the safety and tolerability of IV administration of CD-NP and the dose relationship of CD-NP on improvement of clinical symptoms and renal function in ADHF patients.
NCT00351559
This study is designed to evaluate the safety and efficacy of a leukocyte gene expression profiling method in the monitoring of asymptomatic heart transplant patients for acute rejection.
NCT00673075
This study is being done to see if the blood pressure lowering effect of an approved drug nebivolol is comparable to that of another approved drug carvedilol for the treatment of hypertension in patients who have coronary artery disease.
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
