Filter by:This pilot study will help evaluate the effect of singing on heart rate variability and endothelial function (markers of cardiac health). If study results are positive this will support more research on the use of singing in cardiac rehabilitation.
Cardiovascular disease (CVD) is responsible for 1 in 4 deaths in the US annually. Nutrition is an important part of prevention and management of CVD and other chronic diseases, but only about 25% of patients with a chronic disease diagnosis (and about 12% of patients without a chronic disease) receive nutrition counseling from their physician. The investigators plan to validate a diet questionnaire in preparation for the creation of a diet assessment/ intervention tool to increase rates of nutrition intervention in medical care. The aim of this project is to test whether the developed questionnaire accurately identifies individuals at high nutritional risk compared to the Healthy Eating Index- 2015 (HEI-2015) determined by a validated questionnaire.
To date, no studies seems to compare conventional gait rehabilitation program with end-effector RAGT in subacute stroke patients by analysing the variations of gait kinematics beyond clinical multi prospective outcomes. The aim of this pilot study is to evaluate the efficacy of end-effector RAGT in subacute stroke patients in terms of clinical outcomes and gait kinematics, comparing them with conventional gait rehabilitation program.
The clinical Investigation will be performed to compare the safety and effectiveness of the CE certified and established lipoprotein apheresis systems MONET vs. DALI and DIAMED vs. DALI for optimizing the individual therapy of patients with severe dyslipidemia using established and novel efficacy parameters.
The investigators plan to use the recently developed oral carnitine challenge test (OCCT) as a tool to exam individual's trimethylamine N-oxide (TMAO) production capacity from their gut microbiota. By using data collected by OCCT, the investigators defined subjects as high-TMAO producer or low-TMAO producer and apply low carnitine/choline diet as dietary intervention for the high-TMAO producers. After dietary intervention for two months, the investigators conducted OCCT for the participants and compare the TMAO production capacity before and after the dietary intervention.
Cardiovascular disease (CVD) occurs less frequently in women than in juvenile men.Frequently the estrogen deficiency associated with the menopausal state affects cardiovascular outcomes. In fact, in the post-menopausal state, even younger women may experience an increase in the rate of ischemic heart disease (IHD). On the other hand, CVD may also occur in premenopausal young women, due to not well known and/or not clearly investigated mechanisms. In addition, pre-menopausal women with IHD show atypical symptoms and more frequently myocardial infarction vs. angina pectoris. In detail, in these patients IHD is frequently due to mono-vessel coronary heart disease, and to the presence of cardiovascular risk factors such as hypertension, hyperlipidemia and type 2 diabetes. So, it is clear that all these pro-atherogenic risk factors which lead to IHD in women, are significantly lower in the pre-menopausal vs. post-menopausal patients. However, the causes leading to IHD and acute coronary events in pre-menopausal women remain poorly understood and poorly investigated, and these factors might be different from the traditional coronary risk factors evident in the general population. In this context, recently some authors have shown that subcutaneous abdominal fat affects cardiovascular performance at 1 year of follow-up in patients with normoglycemia vs. pre-diabetic. Therefore, here authors can hypothesize that in a population of female subjects, the fat tissue present in the mammary gland and the different degrees of mammary adipocyte infiltration can somehow invalidate the number of cardiovascular events in women of childbearing age. In detail, the different distribution of adipose tissue in the mammary gland can influence the density of the breast, as studied by mammographic examination, which is used to divide breast density into 4 different categories: - Category A: the breast is represented by 80% of adipose tissue and less than 20% by fibro-glandular tissue. - Category B: the breast is represented by adipose tissue in the range of 50-75% and for the rest by fibro-glandular tissue. - Category C: the breast is represented by fatty tissuein the range 25-50% and the rest is from fibro-glandular tissue - Category D: the breast is represented by almost entirely fibro-glandular tissue. Therefore, in the present study authors correlated the 4 different breast categories with CVD and 10-year follow-up IHD in women of child-bearing age. In fact, according to authors' opinion, a breast with higher fat density (category A) might influence the number of adverse cardiovascular events at 10-year follow-up in asymptomatic women. Thus, pre-menopausal women with breast tissue in category A ("fatty breast") as compared to women with prevalence of fibro-glandular tissue ("non-fatty breast") may have a higher frequency of adverse cardiac ischemic events at 10 years of follow-up. On the other hand, the molecular pathways implied in worse CVD in these cohorts of women are not fully investigated. Furthermore, the authors aimed to investigate the expression of inflammatory cytokines and sodium glucose transporter 2 (SGLT2) protein expression, as markers of over-inflammation, at level of breast gland in these cohorts of women. Thus, these markers were analyzed in the breast fat tissue excissed from the fatty vs. non-fatty breast women.
The purpose of this project is to apply a community-based participatory research (CBPR) approach to rigorously refine and test the feasibility and preliminary efficacy of an existing cardiovascular (CV) health and wellness digital application (app) prototype to improve CV health according to the American Heart Association Life's Simple 7 (LS7) framework among African-American (AA) adults within faith communities. The investigators hypothesize that the app-based intervention will be feasible and improve LS7 among AAs from baseline to 6-months post-intervention.
Coordination between different levels of care has been identified as one of the main components of care among people with chronic diseases. In this sense, an adequate referral and counter-reference system facilitates the management of the care process with timely access to the required referral. The objective of this project is to evaluate the effectiveness of a multicomponent strategy that improves the counter- referral process in patients with cardiovascular diseases in the public health system. Population: The study will be carried out in selected hospitals of the provinces of Mendoza, Tucumán and Salta in Argentina. Patients who have been hospitalized with a diagnosis of heart failure, hypertension (requires hospitalization) and / or coronary disease (unstable angina) will be included. Design and methods: a Randomized clinical study by clusters. 10 hospital will be included: 5 will be randomly assigned to receive an intervention to increase the improve counter referral rates (improvement cycles) and 5 to the control branch (usual care). 51 participants will be included in each hospital, in total, 510 participants. Intervention: An innovative vision is proposed, which combines a participatory and dynamic methodology based on improvement cycles. This approach includes the implementation of participatory learning sessions for health providers, involving the effectors of the design of the intervention. In the intervention branch at least 6 workshops (sessions) will be held with the members of the care system, in order to identify opportunities for improvement oriented to the design and application of an innovative intervention based on best practices. Each one of the sessions will constitute an analysis of the improvement cycle, following the following steps: 1) Selection of participants of the initial workshop; 2) Development of work model based on bibliographic review and initial qualitative phase; 3) Initial workshop with effectors for training in continuous improvement, objectives, interventions and data collection; 4) Learning workshops to discuss results, applicability of interventions and modifications to the work plan; 5) Closing session to evaluate preliminary results and discuss continuity of interventions beyond the project. Outcomes: 1) consultation in the PHC after hospital discharge; 2) readmission's; 3) consultations in the hospital; 4) follow-up in the PHC; 5) patient perspective (satisfaction).
INTRODUCTION: Cardiovascular diseases are the main causes of death in Brazil and in the world, associated with a large number of people with physical disabilities and disability, significantly burdening public health expenditures. Some patients end up having the need to do cardiac surgeries. , and consequently suffer complications associated with the surgical process due to prolonged rest in the bed, and complications are directly related to the morbidity and mortality rate in these patients. Thus, cardiac rehabilitation has great scientific evidences that directly impacts functional capacity, quality of life and thus reducing the morbimortality rate of these patients. However, it is worth noting that there is no outpatient cardiovascular rehabilitation service linked to the single health system (SUS) in the Amazon Region, that is, involving phase III of cardiac rehabilitation with defined and structured protocols for the group of patients already mentioned. OBJECTIVE: To analyze the clinical evolution of patients in the postoperative period of coronary artery bypass grafting and / or valve replacement (phase III), in outpatient treatment. METHODOLOGY: It is a a longitudinal study, with quantitative variables to be performed in a single center within a year (12 months). Which will evaluate the effects of phase III cardiac rehabilitation of patients undergoing cardiac surgery through an evaluation, which will evaluate heart rate variability, functional capacity by six-minute walk test, pulmonary volumes and capacities by spirometry, percutaneous strength and ventilatory muscle, MRC scale and manovacuometry, respectively, and the application of a quality of life assessment questionnaire. Subsequently, the protocol of 20 sessions will be applied and at the end the same variables will be re-evaluated. EXPECTED RESULTS: It is expected from the application of this research that the protocol suggested for the phase III cardiac rehabilitation of patients submitted to cardiac surgery will bring benefits to patients, such as improvement in heart rate variability, improvement in functional capacity, improvement in quality of life, and reduction in morbidity and mortality rates.
