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.
NCT00321282
Roughly thirty percent of people that undergo open heart surgery get an abnormal heart beat afterwards known as atrial fibrillation (AF). While not life threatening, this abnormal heart beat increases the likelihood of stroke and delays recovery. There are strategies to prevent post-operative AF, but they are costly and sometimes have undesirable side effects. Therefore, it would be best if we use these preventive treatments only in high risk patients. We intend to develop a risk prediction model based on demographic and electrocardiogram (ECG) findings that will predicted who is likely to get AF. We will develop this model using data already available on patients who have undergone cardiac surgery. The development of this model will use the latest mathematical algorithms similar to those used to study genetic evolution. This type of model is capable of looking at many parameters in an unbiased way, so that only the strongest, independent predictors remain in the final model. Once, the model is developed, we will validate the model by comparing our predictions to actual outcomes previously recorded in the database.
NCT00146679
The overall purpose of this study is to test the effects of a nurse managed psychoeducational intervention, consisting of symptom management training (SMT) and cognitive-behavioral intervention (CBI), during the first year after ICD implantation using a 3 group randomized clinical trial.
NCT00850720
The goal of this study is to evaluate specific hormone levels in children undergoing heart surgery in order to identify patterns associated with any unstable vital signs. The data collected will provide preliminary answers to the question "Are hormone values a determining factor for drug administration and dosing levels?" and help establish the benefits of routine steroid and hormone administration. Sixty subjects will be enrolled. Blood samples will be drawn before the surgery,and again nine hours after surgery for analysis. Other patient data such as medications, vital signs, routine lab values and treatments will also be analyzed. As our current standard of care includes routine doses of steroids, we believe this study will increase our general knowledge and improve the care of these critically ill children. The study will also provide the foundation needed for grant support from the American Heart Association, allowing for future larger scale studies.
NCT00833144
Patients often arrive to the Emergency Department with the chief complaint of shortness of breath. The cause of the shortness of breath may be due to many things, such as pneumonia, emphysema, a heart attack, heart failure, and others. It is often very difficult for the physician to determine the cause of the shortness of breath in the first two hours in the Emergency Department. This ambiguity makes treating the patient very difficult. Although a patient could benefit from treatment upon arrival, the emergent treatment of the condition must wait until a final diagnosis is made. Recently, emergency physicians have been using portable ultrasound at the patient's bedside to diagnose numerous conditions, including trauma, blood clots, kidney stones, etc. Recent research suggests that heart failure, one of the causes of shortness of breath, may be diagnosed within 5 minutes or less using ultrasound. Most of these studies come from the intensive care and cardiology. However, no research has yet been performed to determine if emergency physicians can effectively use ultrasound to quickly diagnose and treat heart failure within the first few minutes of a patient's arrival to the emergency department. The hypothesis of this study is to evaluate the ability of residents in emergency medicine to use ultrasound to diagnose patients in heart failure who presented with the chief complaint of shortness of breath. The final diagnosis of the patient upon discharge from the hospital will be compared to the preliminary diagnosis based on the portable ultrasound findings.
NCT00399555
There have been many improvements in the care of children with hypoplastic left heart syndrome (HLHS). This has helped these children survive longer. Because these children now live longer, researchers are recognizing developmental disabilities (the children are behind in their thinking or physical activity) in children with hypoplastic left heart syndrome. The purpose of this research study is to help the investigators learn more about developmental disabilities in children with hypoplastic left heart syndrome. During the time of your child's first surgery for hypoplastic left heart syndrome, a monitor was placed on your child's forehead to measure the oxygen levels in the brain. This monitor is called Near Infrared Spectrometry (NIRS). The researchers involved in this study want to know if oxygen levels in the blood vessels of the brain have any effect on developmental disabilities later in life in children with hypoplastic left heart syndrome. The researchers plan to enroll 60 research subjects.
NCT00359099
This is a retrospective chart review. We hypothesize that patients who have undergone congenital heart surgery, prior to screening of blood products have a significant risk of hepatitis C infection and all such patients would benefit from screening for hepatitis C.
NCT00276237
One of the most common residual lesions in adult survivors of pediatric cardiac surgery is pulmonary valve disease, particularly regurgitation. Multiple studies have demonstrated that placement of a pulmonary valve in such patients, results in improved ventricular function and resolution of symptoms. However, the optimal prosthetic valve for use in the pulmonary position has not been defined. There are essentially three alternatives available: the stented bioprosthetic valve, stentless bioprosthetic "tube" grafts used to replace the entire right ventricular outflow tract and mechanical valves. All three of these valve options have been used in adults with congenital heart disease at Emory Healthcare and at Children's Healthcare of Atlanta at Egleston. The goal of this study is to evaluate and compare the indications and short and mid-term outcomes for these alternative therapies.
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.
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.
NCT00863707
This study is intended to assess the safety and tolerance of regadenoson in subjects with renal impairment.
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.
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.
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.

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.
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.
NCT01229137
Assessment of sensor parameter in patients with heart failure.
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.
