Filter by:The aim of the study is to determine the analytical characteristics of the microRNA enzymatic immunoassay (miREIA) method and to determine various relations among miRNA biomarkers and heart failure (HF) with reduced ejection fraction(HFrEF). The investigators assume that there are correlations between levels of selected miRNA and HFrEF. These correlations provide information to formulate pathophysiological conclusions, which will significantly contribute to early diagnostics and also the treatment of this disease.
In heart failure patients, neuropsychological disorders have been prospectively linked to frequent hospitalizations, recurrent cardiac events, and mortality. Cognitive dysfunction is also a frequent comorbidity in heart failure (HF) patients. The benefit of cardiac rehabilitation between patients with cognitive dysfunction and patients without cognitive dysfunction is unknown. Investigators hypothesize that patients with cognitive dysfunction benefit more from cardiac rehabilitation programs than patients without cognitive dysfunction.
Background: Heart failure (HF) is a chronic disease with a very important and increasingly severe social and health impact with a prevalence of 6.8% in Spain. HF with preserved ejection fraction (HFpEF) represents approximately 50% of all patients with HF. In the absence of pharmacological treatments that have succeeded in reducing mortality or morbidity in this pathology, it is recommended that interventions be directed at prevention, symptomatic treatment of HF and treatment of comorbidities to avoid exacerbations, thus physical exercise is recognized as an important adjunct in the treatment of HF and is recommended by the guidelines of the American College of Cardiology (ACC)/American Heart Association (AHA) and the European Society of Cardiology (ESC). Currently, aerobic exercise is the most studied physical exercise in this population, but in recent years high-intensity interval training (HIIT) and the combination of aerobic exercise with strength training (combined exercise) have emerged. Objectives: The overall objective of this study is to compare the effectiveness of combined training and HIIT on exercise capacity, diastolic function, endothelial function, and arterial stiffness in patients with HFpEF. The specific objectives of this study are: a) to compare the effectiveness of combined training and HIIT on quality of life in patients with HFpEF and b) to analyze the cost-effectiveness of combined training and HIIT versus conventional treatment in patients with HFpEF. Methodology: The ExIC-FEp study will be a single-blind randomized clinical trial with 3 arms (combined exercise, HIIT and a control group), conducted at the Health and Social Research Center of the University of Castilla-La Mancha, to analyze two types of supervised physical exercise in patients with HFpEF for 6 months. Patients with HFpEF will be randomly assigned (1:1:1) to the combined exercise, HIIT or control group. All participants will be examined, at baseline (prior to randomization), at three months (mid-intervention) and at six months (at the end of the intervention). Participants will undergo physical examination, echocardiography, maximal cardiopulmonary stress test, and measurement of endothelial function and arterial stiffness. In addition, sociodemographic variables, quality of life, physical activity, adherence to the Mediterranean diet, strength, spirometry and blood sampling will be measured. Expected scientific contributions: this randomized clinical trial will represent a a significant advance in the scientific evidence available on the efficacy of physical exercise in the treatment of HFpEF, through: (a) transfer of the results to physicians, nurses and patients; (b) dissemination of results through scientific articles, doctoral theses and participation in congresses; (c) press releases and press conferences with the aim of disseminating the research results to the population; (d) dissemination through social networks to improve the social impact; and (e) design and content development of a web page.
Heart failure (HF) is a leading cause of death, hospitalization, and healthcare system expenditure in Canada. While care in HF clinics - multidisciplinary clinics that focus on optimal management of HF - improves health outcomes in HF, there are disparities in access to such care across our province. To respond to the needs of patients and the health care system, the investigators propose to develop and implement a virtual model of care that will enable Canadians with HF to receive outpatient HF care and medical optimization remotely. The investigators will assess the feasibility of this model of care in a pilot randomized controlled trial, and collect feedback from patients and providers. The investigators hypothesize that virtual clinics will be feasible. The investigators will also measure healthcare processes, and use these to guide a larger clinical trial that will measure clinical outcomes in patients receiving virtual versus usual care.
The overall purpose of this study is to investigate whether pulmonary limitations that increase the oxygen (O2) cost of breathing impact dyspnea on exertion (DOE) and peak exercise capacity in patients with HFpEF and obesity. As per investigator's hypothesis, obesity is likely a significant contributor to DOE and exercise intolerance in patients with HFpEF.
This is a multicentric, prospective, observational study with two cohorts and adjunctive procedure. It aims at collecting and analyzing data about the function of an innovative hospital-territory integration health service for the management of patients with intermediate urgency, or emergency department "white codes." This service, activated in the participating centers, will be provided in two alternative modalities, one so-called "dual specialty" (cardiology and diabetes specialist outpatient clinic) and a second one more focused on the figure of the specialist in Internal Medicine. The investigators will monitor the population treated in these centers (presenting complaint, medical history, clinical-radiological data, performed therapies and overall health path) and the degree of satisfaction of the General Practitioners who sent their patients there and the degree of satisfaction of the patients themselves. The data collected will also be used to evaluate the effectiveness of the outpatient clinics in terms of reducing improper admissions to the Emergency Departments and hospitalizations. The two modes of service delivery will be compared. This is an 18-month study, sponsored by our Scientific Directorate and carried out on a nonprofit basis. The study will enroll 246 patients and 30 healthy volunteer General Practitioners. The clinical trial will be conducted in accordance with Good Clinical Practice standards.
The goal of this study is to better understand the effects of a sodium-glucose transport protein 2 inhibitor, dapagliflozin, added on to standard of care on heart and lung function and circulating metabolites (substances created when our bodies break down food, drugs, or its own tissues) in patients with chronic kidney disease.
This is a one-day, proof-of-concept, pilot study of portable oxygen concentrator (POC) administration and Six Minute Walk Test (6MWT) distance in patients with stable chronic heart failure.
In this study, patients with endocardial myocardial biopsy were selected to observe the safety of the operation, and pathological examination was performed. If necessary, special tests such as viral examination, mass spectrometry and molecular biology were performed to confirm the diagnosis, and follow-up was performed.
Aims: To evaluate the preliminary efficacy of Health Coaching in empowering hospitalised chronic heart failure patients. Methods: pre-post quasi-experimental pilot study was carried out with 59 patients, allocated into the pre-intervention group (N=29) and post-intervention group (N=30) in a cardiology ward of a hospital. The intervention consisted of the knowledge traslation acquired on health coaching by the nurses of the cardiology unit to their care activity with CHF patients. The Patient empowerment in long-term conditions Questionnaire was used to measure heart failure patients: Attitude and sense of control; Shared and informed decision-making; and Information seeking and peer sharing, on two occasions: T1, pre-intervention, and T2, after completion of the intervention.
