Filter by:The purpose of this study is to determine the effect of remote ischemic preconditioning on exercise capacity in patients with heart failure.
Heart needs constant supply of energy to continue working. Phosphorus magnetic resonance spectroscopy allows us to measure energy produced in the heart. The purpose of this study is to determine if the energy production is reduced in failing heart.
The effect of cardiac pacing leads on tricuspid regurgitation is unclear. This study will determine whether using a smaller diameter leads and an alternate position in the ventricle, the proximal septum, will reduce tricuspid regurgitation than larger leads placed in the apex.
Ischemic cardiomyopathies are a leading cause of death in both men and women. When a person has a heart attack, blood is unable to reach a certain area of the heart, and if the blood supply is not re-established quickly, that area of the heart can suffer permanent damage. While recovery from a heart attack can be managed through medications and lifestyle changes, these treatments can not reverse the all damage to the heart. Current research is focusing on the development of cell-based therapies using stem cells to repair organs that have been irreversibly damaged by disease. A specific form of stem cells, called adult mesenchymal stem cells (MSCs), has shown promise for heart repair. This study will evaluate the safety of injecting MSCs directly into the heart to repair and restore heart function in people who have had a heart attack and who have chronic myocardial ischemia with heart failure.
This study is to collect data and learn more about the Vscan Ultrasound Imaging System. It is an "observational" study with no additional procedures or intervention prescribed other than using the Vscan along with a routine medical physical exam.
Evaluative pilot study for safety and feasibility with administration of autologous bone bone marrow derived mononuclear cells by endoventricular catheter into the normal border zone fo the ischemic lesion.
The STOP-HF study is a prospective, randomized, controlled trial recruiting asymptomatic individuals with risk factors for left ventricular dysfunction from 50 primary care clinics in Dublin and south east Ireland. It is designed to determine whether using natriuretic peptide measurement as a screening tool following a general cardiovascular risk factor screen will reduce the prevalence and severity of ventricular dysfunction in conjunction with specialist follow-up at St. Vincent's University Hospital.
The main objective of this study is to compare the time from randomization to the first recurrence of any ventricular tachycardia (VT) in patients undergoing VT ablation (for stable VTs) and substrate ablation (for unstable VTs) after an initial episode of stable VT and patients not undergoing ablation, with both groups under the protection of an ICD.
This study will test the hypothesis that elective use of the Intra-Aortic Balloon Pump (IABP) in patients undergoing high-risk Percutaneous Coronary Intervention (PCI) will reduce the rate of in-hospital major adverse cardiac and cerebrovascular events compared to patients who are managed without planned insertion of IABP.
Coronary artery disease (CAD) is a common disorder that can lead to heart failure. Not all people with CAD are eligible for today's standard treatments. One new treatment approach uses stem cells—specialized cells capable of developing into other types of cells—to stimulate growth of new blood vessels for the heart. This study will determine the safety and effectiveness of withdrawing stem cells from someone's bone marrow and injecting those cells into the person's heart as a way of treating people with CAD and heart failure.
