Filter by:The purpose of this pilot study is to exploratively test the basic feasibility of a clinical trial for the controlled investigation of the efficacy and effectiveness of iATROS digital therapy management in the treatment of patients with arterial hypertension within the framework of a clinical trial. In addition, the results of the treatment will be used to generate an initial data basis for the effectiveness of treatment with iATROS.
This study seeks to investigate the clinical value of novel echocardiographic indices, including myocardial work parameters, during the acute phase of heart failure hospitalization. The trajectory of novel echocardiographic indices from the start to the end of hospitalization will be captured, as a means to unravel and subsequently better understand the diverse pathophysiology of different phenotypes of the heart failure continuum. Correlation between novel echocardiographic indices with clinical data, biochemical data, different heart failure phenotypes, and therapeutic maneuvers will be attempted. Prognostic implications of those indices will be explored.
Cardiovascular diseases (CVDs) are the number one cause of death in America and most of the post-industrial world. Hypertension is a leading risk factor for CVDs including stroke, myocardial infarction, and heart failure. Black Americans suffer from the highest rates of hypertension of any racial/ethnic group in America, among the highest in the world. There are also well-documented racial disparities in vascular dysfunction (e.g., endothelial dysfunction, arterial stiffening). Thus, racial disparities in hypertension and vascular dysfunction exacerbate the burden of CVDs, with Black Americans being 30% more likely to die from CVD than any other race in the US. It is established that mitochondrial dysfunction contributes to vascular dysfunction. However, there is a knowledge gap regarding whether targeting mitochondrial dysfunction attenuates oxidative stress, vascular dysfunction, and CVD risk among Black adults at heightened CVD risk. Thus, the investigators will conduct an 8-week trial with the mitochondrial antioxidant MitoQ in middle-aged and older Black and non-Black adults. Our overarching hypothesis is that mitochondrial dysfunction contributes to heightened oxidative stress, vascular dysfunction, and higher BP in Black adults; and that MitoQ will attenuate these racial differences. Importantly, the investigators will also assess social determinants of health (e.g., income, neighborhood disadvantage, discrimination) and health behaviors (e.g., diet, physical activity) and uncover their role in oxidative stress, vascular function, and BP Regarding methodology, the investigators will perform blood draws, vascular testing, preceding and following an 8-week, 20mg daily consumption of MitoQ and placebo. The investigators will also measure urine biomarkers of kidney function and blood pressure in adults (45-75 years old).
Chronic obstructive pulmonary disease (COPD) is a disease of the lungs that makes it hard for people to breath. Those with COPD spend considerably more time sitting and lying and less time performing physical activity than healthy individuals. Those who are the most sedentary have a greater risk of heart and blood vessel disease, which may lead to an early death. This project will investigate the effect of sitting still for 3 hours on blood vessel health in individuals with COPD. It will also investigate whether breaking up the amount of time patients sit with regular short bouts of walking (5 minutes each hour) at a comfortable pace chosen by the patient can have a positive effect on maintaining the health of their blood vessels. It is hypothesized that blood vessel health will be worse after 3 hours of sitting compared to when the sitting is broken up by short bouts of walking.
Obtain blood samples for generation and maintenance of induced pluripotent stem cells (iPSCs) and genomic/DNA sequencing for biomedical research that will improve the understanding and treatment of pediatric cardiovascular disease
This study aimed to discuss the correlation between interdialytic weight gain and cardiovascular diseases in children with end-stage kidney disease undergoing chronic hemodialysis. The cardiovascular parameters used include left ventricular hypertrophy, systolic and diastolic function, carotid intima-media thickness, myocardial circumferential strain, and strain rate.
This study aims to obtain data on the potential influence of Vine to Bar product(s) containing Chardonnay marc on cardiometabolic health. These initial studies will inform the design and timing of data collection for future dietary intervention trials that will examine the influence of Chardonnay marc intake on outcomes/biomarkers of both cardiometabolic health and the gut microbiome. This includes collecting data on the potential differences in response to the products based on the unique food matrix for each of the products that will be tested. Moreover, as there is a paucity of data on the influence of cocoa flavanol intake on vascular function beyond 4 hours post intake, the response of the selected outcomes will be assessed after 6 hours of flavanol intake. This is a time point that captures the increased circulating presence of microbial derived flavanol metabolites.
This study is aimed to investigate the changes in pharmacokinetics and efficacy of antiplatelet agents before and after distal gastrectomy in gastric cancer patients taking oral antiplatelet agents for primary or secondary treatment for cardiovascular disease and to evaluate its impact on the occurrence of postoperative bleeding complications and thromboembolic events.
Background. Atherosclerotic cardiovascular disease (ACVD) comprising coronary disease, cerebrovascular disease, peripheral artery disease, and aortic atherosclerosis caused 8.9 million deaths worldwide according to reports submitted by the World Health Organization during 2019, the development and progression of atherosclerosis is favored in the presence of modifiable risk factors such as dyslipidemia. In Mexico, during the period from December 29, 2019, to August 29, 2020, 141,873 deaths from heart disease were reported, even above the 108,658 deaths from SARS COV2 in the same time period. Although it is known that the Mexican mestizo population is susceptible to certain metabolic lipid disorders related to genetic variants, the frequency of dyslipidemia in patients with high cardiovascular risk is unknown to date and may be responsible for this increase. On the other hand, it has been shown that lowering LDL-C levels in this population by means of the pharmacological or dietary treatment stated the current guidelines, decreases chance of death, heart failure, angina, re-infarction or need for coronary revascularization; however, there are still patients not achieving treatment goals. Consequently, it is suggested that through the implementation and correct use of technological tools it is possible to increase efficiency in the medical follow-up of patients, allowing for appropriate lipid levels, like other chronic degenerative diseases such as diabetes and systemic arterial hypertension. Objective. To describe the frequency of dyslipidemias in high-risk and very high-risk patients with atherosclerotic cardiovascular disease, who are IMSS beneficiaries, and to analyze the impact of using an application to achieve dyslipidemia treatment goals at one-year follow-up. Hypothesis For the National Register: Not required since the main objective is to carry out a national register of dyslipidemias. For the use of the application: Null hypothesis: The use of the application does not change the frequency of patients with high and extremely high atherosclerotic cardiovascular risk who achieve the goals of dyslipidemia treatment during one year of follow-up.
Fenofibrate, a peroxisome proliferator-activated receptor-alpha (PPAR-a) agonist known to improve diabetic dyslipidemia, has been proposed as a drug to prevent cardiovascular disease (CVD) in type 2 diabetes (T2D). However, the results of clinical trials have been mixed. Supporting the hypothesis that these disappointing results hide a genetic heterogeneity in the CVD response to fenofibrate, a common genetic variant (rs6008845) in the gene coding for PPAR-a has been found to dramatically influence the ability of this drug to reduce CVD events in the ACCORD Lipid trial (PMID:31974142). The aim of this study is to validate these findings by dissecting the pathways and mechanism through which this variant exerts such a modulatory effect, by means of a randomized clinical trial. If successful, this project will pave the way to a precision medicine approach to prescribe fenofibrate optimally, offering a cardio-protective drug to those patients that are most likely to experience a robust benefit from this medication.
