Filter by:Pulmonary arterial hypertension (PAH) is a serious, progressive disease that causes pulmonary arterial pressure, significantly affecting functional capacity and quality of life. Over the last few years, knowledge in pulmonary hypertension has evolved consistently and significantly. New diagnostic and treatment algorithms were combined based on the results of several clinical studies that showed the usefulness of new tools, as well as the effectiveness of new drugs as well as non-pharmacological treatment. The new guidelines felt the benefits of physical exercise in individuals with PAH, with promising results in improving symptoms, exercise capacity, peripheral muscle function and quality of life. With the COVID 19 pandemic, the complex scenario was for world health, and social distancing made it impossible to carry out individual outpatient rehabilitation, in groups and in person, indicating the need for rehabilitation programs, including physical training, to be adapted to the domicile. New alternative modes of pulmonary rehabilitation include home-based models and the use of telehealth. Telerehabilitation is the provision of rehabilitation services at a distance, using information and communication technologies. To date, there has been no evaluation of the clinical efficacy or safety of telerehabilitation in the population affected by PAH.
In this proposal, the investigators will demonstrate the feasibility and noninferiority of telerobotic ultrasonography as compared to traditional manual acquisition in performing a limited carotid Duplex examination and in carotid plaque detection.
Cardiovascular disease is the leading cause of death worldwide. Advanced cardiovascular imaging using Magnetic Resonance Imaging (MRI) has proven to be effective in providing gold standard myocardial tissue characterization. Moreover, the intrinsic advantage of MRI's lack of exposure to ionizing radiation is particularly beneficial. At the same time, blood work can be very useful in early detection of certain cardiomyopathy, such as amyloid. However, there is a lack of agreement of on which markers are the most sensitive. This multi-study will allow us the unique opportunity to form a more comprehensive understanding for various cardiovascular diseases. Our team has developed novel cardiac MRI techniques that leverages endogenous tissue properties to reveal a milieu of deep tissue phenotypes including myocardial inflammation, fibrosis, metabolism, and microstructural defects. Among these phenotypes, myocardial microstructure has proven to be most sensitive to early myocardial tissue damage and is predictive of myocardial regeneration. In this study, the investigators aim to further study the importance of cardiac microstructure revealed by MRI in patient and healthy population and compare this novel technology with conventional clinical biomarkers.
The primary aim of the proposed investigation is to examine the hypothesis that a relatively short period of rhamnan sulfate supplementation would improve key markers of vascular dysfunction in middle-aged and older adults with at least one risk factors for cardiovascular disease.
The primary goal of this non-profit single-centre randomized pilot interventional study is to evaluate the acceptability of a daily telemonitoring of five vital parameters (heart rate, respiratory rate, blood oxygenation, blood pressure, and body temperature) using a medical device in advanced cancer patients with relevant cardiovascular and respiratory comorbidities assisted at home. In addition to the standard home care, participants in the intervention group will keep the medical device at home. They will register five vital parameters (heart rate, respiratory rate, blood oxygenation, blood pressure, and body temperature) once a day for eight weeks. Participants belonging to the control group will receive standard home care. The secondary goals of this study include the following: - Analyzing the effect of telemonitoring on patients' quality of life and psychological status. - Observing the possible effects of telemonitoring on the caregiver care burden. - Assessing the possible effects of telemonitoring on the caregiver perceived satisfaction with the home care received. - Comparing the number of physician and nurse home visits and phone calls between the patients using the device and patients in standard home care. - Comparing the number of emergency room visits, admissions, and hospitalization days between the patients using the device and patients in standard home care.
Cardiovascular disease is the leading cause of death worldwide. It is becoming clearer that heart failure (HF) is closely associated with body's metabolism. Even before the heart becomes weaker, it responds to the stresses by changing the fuels it burns, which results in a reduction in the heart's metabolic efficiency that worsens the heart's condition. Since the heart burns so much fuel and consumes fats and carbohydrates along with other available substrates, any changes in its metabolic efficiency could impact metabolism throughout the body. Specifically, HF is characterized by limited flexibility in substrate utilization leading to an overall energetic deficit. Such energetic deficit is associated with progressive remodeling and alter cardiac hemodynamics. For example, obesity is a widely known risk factor for cardiovascular disease likely lie in how the heart handles energy (substrate utilization and energetics). One commonly recommended treatment for cardiovascular disease, especially coronary artery disease (CAD) or congestive heart failure (CHF), is cardiac rehabilitation. Cardiac rehabilitation for symptomatic cardiovascular disease has been shown to promote a healthy lifestyle, improve physical health and reduce cardiovascular death iii with an apparent dose-dependent response. Participation results in a reduced risk of hospitalization and revascularization procedures, and improved functional status in randomized controlled trials. Thus, cardiac rehabilitation is recommended for individuals with symptomatic CAD or CHF by the American College of Cardiology and American Heart Association. In addition, exercise training in preclinical animal models mirroring the exercise component of cardiac rehabilitation routines have shown increased myocardial regeneration and cardioprotective molecular effects ameliorating adverse myocardial remodeling. Despite these benefits, there is vast heterogeneity in the efficiency of cardiac rehabilitation on the individual level with large variances in improved exercise capacity and cardiac function recovery. Personalization of cardiac rehabilitation necessitates a non-invasive approach to monitor the direct beneficial effects on the heart and more ideally, predict efficacy at baseline. Taken together, understanding how metabolic interventions including bariatric surgery and cardiac rehabilitation change myocardial structure and function is critical for the prevention, diagnosis and prognosis for patients with cardiovascular diseases. Advanced cardiovascular imaging using Magnetic Resonance Imaging (MRI) has proven to be effective in providing gold standard myocardial tissue characterization. Our team has developed novel cardiac MRI techniques that leverages endogenous tissue properties to reveal a milieu of deep tissue phenotypes including myocardial inflammation, fibrosis, metabolism, and microstructural defects. Among these phenotypes, myocardial microstructure has proven to be most sensitive to early myocardial tissue damage and is predictive of myocardial regeneration. In collaboration with cardiologists at Cleveland Clinic, the investigators aim to study how myocardial microstructure revealed by cardiac MRI changes cardiovascular disease patient population before and after metabolic interventions.
Asprosin, a recently discovered glucogenic adipokine, is mainly synthesized by white adipose tissue and released during fasting. Appetite, glucose metabolism, insulin resistance, cell apoptosis, etc. asprosin is associated with diseases such as diabetes, obesity, polycystic ovary syndrome, and cardiovascular diseases. Periodontal tissue may act as a source of endocrine-like inflammatory mediators (such as TNF-α, IL-6 and IL-1) that are important in periodontal inflammation and can affect glucose and lipid metabolism. Production of TNF-α and IL-6 in adipose tissues strengthens the relationship between cardiovascular diseases and periodontitis. Investigators postulated that asprosin may be a candidate for explaining the triangular relationship between cardiovascular and periodontal disease.
With the cessation of estrogen production at menopause, the risk of cardiovascular disease like arthrosclerosis, myocardial infarction and stroke increases dramatically. Physical activity is the single most powerful "drug" for maintaining and improving cardiovascular health, but recent data suggest that the positive effect of physical activity is lost at menopause. In this project the investigators will follow a cohort of 200 women from before the women enter menopause and until at least 10 years past menopause. By advanced invasive methodologies the investigators will monitor the changes that occur in the blood vessels of the circulation, the heart and the brain and combine this with microRNA sequencing of blood and tissue samples.
The China PEACE SMARTER trial is a cluster ramdomized trial aiming to assess the effectiveness of village doctor-led tailored health management on risk reduction of high-risk individuals for cardiovascular disease.
The aim of this study is to investigate the effect of different treatment strategies on mitochondrial function and to correlate in-vitro results to findings from in-vivo measurements of mitochondrial function. The authors hypothesize that interventional revascularization and therefore the restoration of blood and oxygen supply is more relevant to mitochondrial function compared to the effect of exercise training.
