Filter by:The purpose of this study is to learn more about how a drug commonly used to treat multiple myeloma can affect the heart. In this study, the investigators will learn whether a drug called how a drug (called bortezomib, or Velcade) receive for multiple myeloma affects the heart. Bortezomib is part of the standard treatment and its effects on multiple myeloma is not being studied here. The investigators want to learn whether damage occurs to the heart after taking bortezomib for multiple myeloma, whether it is reversible, and we can predict damage to the heart before it occurs.
The purpose of this study is to test the acceptability and feasibility of a "toolkit" of patient decision aids (PtDAs) for heart failure patients who are considering an ICD implant.
The essential arterial hypotension and allostasis registry is a prospective, observational research that has the purpose of demonstrating that essential blood pressure (BP) disorders and the associated comorbidities are a result of the inappropriate allostatic response to daily life stress. This required a functioning brain orchestrating the evaluation of the threat and choosing the response, this is a mind-mediated phenomenon. If the response is excessive it contributes to high BP, if deficient to low BP, and the BP itself will identify the allostatic pattern, which in turn will play an important role in the development of the comorbidities. To do so, consecutive patients of any age and gender that visit a cardiologist's office in Medellin, Colombia, are recruited. Individuals are classified according to their arterial BP and allostasis and follow them in time to see what kind of diseases develops the most (including BP) in the follow up according to the categorization of the characteristic chosen and after adjustment for confounder's variables. In addition, stress events with their date are registered. HYPOTHESIS The causes of the diseases are multifactorial. Physical, biochemical, psychological, social, and cultural dimensions of development dynamically interact to shape the health development process. A person´s health depends on their: 1. Biological and physiologic systems 2. External and internal environment (a) physical, b) internal behavioural and arousal state as registered by the brain. 3. Their interaction. The allostatic mechanisms to the internal and external stressors (allostatic load) involves a network composed by: 1. Functional systems; mediated by: 1. The Autonomic Nervous System 2. The endocrine system 3. The immune system 2. Structural changes: whenever the internal and/or external stressors are long lasting and/or strength enough, they may induce changes in: 1. Epigenetic, endophenotypes, polyphenism. 2. Plasticity 3. The interaction between a) and b). The network response do not affect exclusively the BP, propitiating the development of comorbidities, which may prompt strategies for prevention, recognition and ultimately, treatment. The allostatic model defines health as a state of responsiveness. The concept of psycho-biotype: The allostasis is the result of both: biological (allostasis) and psychological (psychostasis) abilities. It is proposed that both components behave in similar direction and magnitude. Immune disorders may be associated with the development of cancer. High BP population has a higher sympathetic and lower vagal tone, this has been associated with a decrease in the immune´s system function. Resources and energy depletion: Terms like weathering have been used to describe how exposures to different allostatic loads gradually scrape away at the protective coating that keeps people healthy. It is postulated that High BP individuals have more resources and energy.
Non-ischemic cardiomyopathy and heart failure are highly influenced by the presence of systemic inflammation. Doxycycline is a FDA-approved drug to treat bacterial infections which also shows powerful anti-inflammatory effects. In this study we plan to determine the effects of Doxycycline in patients with stable heart failure and non-ischemic cardiomyopathy on peak of aerobic exercise capacity (peak V02) and ventilator efficiency measured with a cardiopulmonary test.
Medamacs is a prospective, observational study of ambulatory patients with advanced heart failure. The study enrolls patients who have not yet received a Left Ventricular Assist Device (LVAD) but who receive their care at a hospital with a Joint Commission certified mechanical circulatory support program. Medamacs is funded through the Interagency for Mechanically Assisted Circulatory Support (INTERMACS) NHLBI Contract.
The proposed study is a sub-study of the CANTOS trial (A randomized, double-blind, placebo-controlled, event driven trial of quarterly subcutaneous canakinumab in the prevention of recurrent cardiovascular events among stable post-myocardial infarction patients with elevated high sensitivity C-reaction protein (hsCRP) [CACZ885M2301]). The study proposes to perform serial Cardiopulmonary Exercise Tests (CPX) to prospectively measure changes in aerobic exercise capacity in patients with prior myocardial infarction (MI), elevated C reactive protein plasma levels, and symptomatic heart failure with reduced systolic function, who are enrolled in the main CANTOS trial and are randomly assigned to Canakinumab (3 different doses) or Placebo. The subjects enrolled in this substudy will undergo repeated CPX and echocardiograms over the first 12 months of the CANTOS trial. The subjects will received the experimental treatment as randomized in the main CANTOS trial and they will not receive any additional experimental treatment as part of the sub-study. This study is a an Investigator-initiated (Dr. Abbate) single-center (Virginia Commonwealth University) sub-study of the CANTOS trial, supported by Novartis pharmaceuticals.
The purpose of this trial or study is to determine if pacemaker therapy can be a beneficial alternative to conventional medical therapy in patients with a history of moderate heart failure. The investigators are looking to enroll approximately 180 people in this trial. Patients will be randomized in two groups. One group will be implanted with a pacemaker and will continue to receive conventional medical therapy as prescribed by their doctor. The second group will continue to receive conventional medical therapy as prescribed by their doctor and will not be implanted with a pacemaker. Clinical histories, physical exams, and external device testing will be collected both at the time of enrollment in the trial and during follow-up study visits. Patients who enter the study will be seen for study visits at 1 month, 3 and 6 months.
Probenecid is an FDA approved drug for the treatment gout and hyperuricemia. It has been used safely in humans for decades for this and other indications. The investigators have recently discovered that this drug can also stimulate other receptors in the heart and therefore improve its function. The hypothesis of this study is that probenecid can be used to improve the function of the heart and therefore the symptoms in patients with heart failure.
The primary aim of the study is to determine safety, tolerability and feasibility of bilateral carotid body resection in patients with systolic heart failure and peripheral chemoreceptor hypersensitivity. The secondary aim is to assess potential efficacy of bilateral carotid body resection.
The investigators aim to determine if patients with systolic heart failure treated with prasugrel achieve greater platelet inhibition compared to those treated with clopidogrel.
