Filter by:Investigators will test a new approach to a form of heart failure (HF) with no current treatment proven to reduce death rates or hospitalisations. Over a third of HF cases have preserved ejection fraction (HFPEF) often on a background of high blood pressure (BP). These "stiff" hearts pump strongly but fill inefficiently resulting in poor exercise capacity and high death rates. Treatments that help when heart pumping action is poor are of no benefit in HFPEF. Recently a simple catheter procedure removing excess nerve signals to and from the kidneys ("renal denervation"; RDN) has been able to reduce BP in patients with high BP resistant to multi-drug treatment. Through removing excess nervous drive to the kidneys, heart and circulation this treatment has promise in HF. The investigators will compare effects of RDN and standard medical treatment on heart function, exercise capacity and quality of life in 144 patients with HFPEF
The purpose of this study is to determine whether the Hospital-Community-Family-Care Management Platform for Chronic Heart Failure reduces the mortality, readmission rates and costs of the subjects with CHF.
The purpose of this study is to determine whether electrocardiogram, echocardiography, cardiac MRI, sera biomarkers can improve early detection of myocardial involvement and clinical outcome.
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.
Cardiac resynchronization therapy (CRT) is one of the lastest recommended treatments in patients with refractory symptomatic chronic heart failure with reduced ejection fraction (HFREF). Despite clear guidelines 20 to 40 % of implanted patients are not clinically ameliorated. They are called the "non responders". Patient selection seams to be one of the key to improve the efficiency of CRT. This protocol try to assess positive predictive factors to CRT by a multimodal approach.
The aim of present study is to evaluate the efficacy and safety of Extended-Release Carvedilol Sulfate versus Sustained-release Metoprolol Succinate in Patients With Mild or Moderate Chronic Heart Failure.
The ICD Registry™ is a nationwide quality program that helps participating hospitals measure and improve care for patients receiving implantable cardioverter defibrillators (ICDs) and cardiac resynchronization therapy devices with defibrillator (CRT-Ds). The ICD Registry captures the characteristics, treatments, and outcomes of patients receiving (ICDs). Patient-level data is submitted by participating hospitals on a quarterly basis to the American College of Cardiology Foundation's (ACCF) National Cardiovascular Data Registry (NCDR) which then produces an Outcomes Report of the hospital's data, with comparison to both a volume peer group (number of ICD patients submitted annually) and the entire ICD registry data set.
A prospective observational multi-centre study for the validation of the ApneaScan algorithm (integrated in ICD devices (with or without cardiac resynchronization therapy function) of the "Incepta" series for the screening of sleep disordered breathing in patients with stable symptomatic chronic heart failure, using portable polygraphy monitoring device ("Embletta Gold") as reference for the Apnea-Hypopnea-Index (AHI). Secondary objectives are the detection of severe sleep disordered breathing in patients with clinically indicated in-laboratory polysomnography, as well as correlations of the AHI detected by ApneaScan with other clinical endpoints like mortality, hospitalization, atrial fibrillation and ventricular arrhythmia.
To determine whether, and if so, which gas exchange parameters measured on the Shape-HF Cardiopulmonary Exercise Testing System predict 30 and 180 day re-hospitalization in subjects discharged from hospitalization for an episode of acute decompensated heart failure.
The study purpose is to evaluate the safety and feasibility of the CORolla™ TAA in two treatment groups, "CORolla™ Stand-alone group" and " AVR & CORolla™ Add on group".
