Filter by:This study compares the accuracy of fusion imaging (Fusion Roadmap) versus real-time X-ray imaging (Roadmap) during catheterization of supra-aortic trunks of in patients with aneurysms or arteriovenous malformations.
The trial was designed in such a way as to show that the proposed program "Trust" increases the proportion of patients who adhere to therapy in the cohort of those with coronary heart disease for two years after successful revascularization by using thrombolytic or stenting of the coronary arteries against the background of myocardial infarction.
Internet-based stress management programs adapted to patients' needs Stress is inevitable, and it has many negative consequences on the health of everybody, but particularly on the health of patients with a cardiovascular disease (CVD). The good news is that patients with CVD can learn to better control their stress through stress management programs. Most stress management programs are offered face-to-face by a trained health care professional. Research has shown that these programs have a positive impact on the health of patients with CVD, including reducing mortality and other risk factors that can make the disease worse (e.g., reduces blood pressure). Because of these benefits, the recommendation is to offer a stress management program to as many patients with CVD as possible. The problem is that their delivery is challenging for most clinics (e.g., too costly to run, health care professionals are not available). This means many good stress management programs never make it to the patient. Patients also face barriers in accessing traditional stress management programs such as stigma or need to travel. Therefore, new approaches are needed to allow findings from research to actually have an impact on the public's health. One of these approaches is to use the internet to deliver stress management programs. The internet has now been used for about 10 years to deliver a range of programs to patients. There are limitations to this approach as well. For instance, 40-60% of patients who will use an internet-based program will not benefit from it. These patients need more support or guidance to get the most out of their internet-based program. This is the problem addressed using the proposed innovative trial design. Investigators aim to improve the number of patients with CVD who improve after receiving a stress management program by changing the type and level of support they receive over time. This type of innovative trial design is more and more popular, but has never been used to enhance a stress management programs for patients with CVD.
Researchers at MCW have discovered a new pathway that links the type of bacteria present in the intestines to the severity of heart attacks. This discovery of a relationship between intestinal bacteria, bacterial metabolites, and severity of heart attacks means that for the first time, the investigators may be able to determine a person's probability of having a heart attack via non-conventional risk factors. This may provide opportunities for novel diagnostic tests as well as a potential for therapeutic intervention. The link between gut microbiota and the severity of heart attacks may also lead to novel therapeutic approaches (probiotics, non-absorbable antibiotics) to prevent heart attacks from happening. The studies proposed will test the hypothesis that altered intestinal microbiota are mechanistically linked to the pathogenesis of cardiovascular disease. The investigator's objective is to determine whether inflammatory markers in the blood are decreased and endothelial cell function improved by a probiotic in patients with established coronary artery disease. Furthermore, the investigators wish to elucidate a mechanism by which the gut microbiota regulates serum inflammatory markers. 1. Specific Aim 1 will determine the impact of a probiotic on circulating leptin and TMAO levels, conventional risk factors for cardiovascular disease and diabetes (total cholesterol, LDL cholesterol, oxidized LDL, triglycerides, C-reactive protein, serum amyloid A, fibrinogen and adiponectin, glucose-dependent- insulinotropic polypeptide (GIP), glucagon-like-peptide (GLP-1), glucagon, insulin), and their relationship to the intestinal microbiota (15 representative microbial groups) as non conventional risk factors. Several blood samples will be collected to measure biomarkers. Participants will provide periodic stool samples in order to measure gut bacterial biodiversity. Lastly, endothelial cell function (flow mediated dilation) will be measured in order to assess blood vessel function. 2. Specific Aim 2 will determine the impact of a probiotic on metabolites derived from the intestinal microbiota as candidates for non-conventional risk factors of cardiovascular disease. The relationship between metabolites derived from the intestinal microbiota, endothelial cell function and risk factors for cardiovascular disease identified in Specific Aim 1 will be correlated.
Cardiac rehabilitation is a programme of exercise and health advice for people recovering from heart disease. Pulmonary rehabilitation is a similar programme for people with chronic lung disease. For both groups of patients, taking part in rehabilitation can lead to improvements in health and well-being. However, only 30% of patients complete their agreed rehabilitation programme. This costs the NHS millions of pounds every year. This project aims to investigate whether a motivational-based intervention, underpinned by self-determination theory and motivational interviewing, will enable staff to encourage more patients to take part in physical activity (PA). Staff will be trained with the new communication skills and will then deliver the rehabilitation programme. The session content will not change, just the way in which staff speak to patients. This will be a two-phase study. Phase A will take a qualitative approach collect patient and staff feedback about the current rehabilitation programme, before using this information to develop and pilot the intervention. Phase B will then assess the feasibility of the intervention within cardiac and pulmonary rehabilitation. Participants agreeing to take part in the phase B will be required to complete an interview and questionnaire at three time points. Patients' personal opinions of the programmes will be extremely important in discovering what can be done to improve rehabilitation for future participants. The main objectives will be to look at whether the intervention increases the number of patients taking part in physical activity. The investigators plan to establish how much physical activity patients take part in whilst they are in rehabilitation, as well as once they have left the programme. This is why participants will be interviewed three and six months after they have finished their rehabilitation programme.
The investigators evaluated the spatial association between, cardiovascular diseases (CVD) and stroke mortality rate with average ambient temperature (Ta) , and then used this relationship to model future temporal trends in mortality from CVD and stroke till the end of century (2099) using different warming scenarios across the mainland USA.
Research aims: 1. To determine if participation in a group-based cognitive behavioural therapy intervention (CBT-I) intervention results in improved sleep quality. 2. To determine if participation in a group-based CBT-I intervention results in improved cardiovascular disease risk factors, and if the CBT-I intervention moderates that relationship.
The aim of the current study was to clarify the relationship between protein intake and health by using a very large, general population cohort study, UK Biobank, to study the associations between reported protein intake (expressed in g/day, g/kg/day and % of total energy intake) and three health outcomes (all-cause mortality, incidence CVD and cancer).
In this cross sectional study, county level data for CVD and stroke mortality, and prevalence of T2D, were combined with per capita densities of FFR and FSR and analysed using multiple and simple linear regression. Mortality and diabetes prevalence were corrected for poverty, ethnicity, education, physical inactivity and smoking to reduce confounding effects.
Cardiovascular disease and malignancies account for more than 70% of all causes of mortality and morbidity in Italy. There is a subtle balance between genetic determinants and lifestyle, that often defines the line between health and sickness. So far studies aiming at identifying risk factors have mainly come from Northern Europe and the USA. It was to understand this balance between genetics and environmental determinants better, and to tailor appropriate preventive strategies for Italian and other Southern European populations, that the Moli-sani study was launched, transforming a small Italian region into a large scientific laboratory: the "Molise lab". Each participant received a thorough medical check-up at no cost to either him/her or the national health service, resulting in thousands of hours of free public health care. With a completely computerized system, Moli-sani is a "paperless" study, in which researchers and participants communicate using recently developed technologies such as mobile phone text messages (SMS). The biological data bank (the "MoliBank") is one of the largest in Europe. Paying particular attention towards innovation and new technologies, the Moli-sani study has placed itself at the cutting edge of a new paradigm crossing research and prevention
