Filter by:This study evaluates the percentage of patients that reach the objective levels of LDL cholesterol, glycosylated hemoglobin and blood pressure recommended by clinical guidelines after an acute coronary syndrome, following strategies of pharmacological optimization based on algorithms. The investigators hypothesize that the use of algorithms designed and protocolized within a cardiac rehabilitation program after an ACS to optimize pharmacological treatment is effective and safe to improve the control of risk factors in patients with high cardiovascular risk.
Heart attacks remain a common cause of death throughout the world. The most common initiating event is the formation of a blood clot within the coronary arteries occluding blood supply to the heart. However, we know that thrombus often occurs within the coronary arteries without causing any symptoms, and may be found in patients with stable angina. We wish to investigate whether blood clots within the coronary arteries can be detected in patients who have had a heart attack and in patients with stable angina using combined positron emission tomography and magnetic resonance (PET-MR) imaging. If possible, this may provide a safe and noninvasive means of identifying patients at higher risk of heart attacks. The study will be conducted in Edinburgh Heart Centre and a total of 40 participants will be recruited from the cardiology wards, outpatient clinics and day case unit. Participants will be asked to undergo a single PET-MRI scan in addition to invasive angiography as part of standard care (non-research procedure). During the invasive angiogram procedure, an additional imaging test may be performed called Optical Coherence Tomography to provide images from within the heart blood vessels.
The purpose of the study is to see whether the antibiotic combination of 100mg doxycycline, 500mg azithromycin and 300mg rifabutin is a safe and effective treatment for coronary artery disease which has not responded to 'standard treatment'. Coronary artery disease is the process of plaque build up within the walls of the arteries responsible for supplying the heart with oxygen and nutrients. plaque is usually made up of fatty deposits, minerals and various amounts of tissue and white cells which eventually narrows the artery, reducing blood flow to the heart. The resulting damage and build up of fat leads to inflammation of the arterial wall and eventually the arteries narrow. The researchers involved in this study consider that a pathogen called Chlamydophila pneumoniae, which can live inside cells may cause this inflammation of the arterial wall. The purpose of this study is to see if treatment with this antibiotic combination in patients with CHD is safe and effective in reducing disease severity measured at coronary angiography and improving quality of life. Approximately 60 patients will be involved in this trial. the treatment period is 90 days with a further 90 day follow up period.
Assess the relationship of Aortic root distensibility and stiffness with the extent of coronary artery disease as assessed by SYNTAX score compared to a matched cohort of patients with normal coronary angiography
Restenosis occurs for many different reasons. Over the years, many predictive clinical, biological, genetic, epigenetic, lesion-related, and procedural risk factors for restenosis have been identified. Smoking is one of most important factors, however the results were contradictory. And the genetic factors of restenosis have been studied mostly in European populations. Based on literature review, study of candidate genes for restenosis in Chinese population was insufficient. With due attention to this matter mentioned above, the investigators aim to preliminary explore genetic variation and smoking effect on clinical restenosis in patients diagnosed with after percutaneous coronary intervention in the Chinese population, with correlation analysis of factors and gene-set analysis of biological pathways related to restenosis and platelet approach were widely used in this study.
The investigators will conduct a feasibility study of an enhanced transitional care intervention, that will: 1) automate identification and risk-stratification of patients with CHF and IHD with social vulnerabilities; 2) incorporate a new standardized social vulnerabilities screening tool into clinical care; 3) enable electronic referrals to community resources; and 4) add novel community-based interventions to the existing medically-oriented transitional care intervention that is the standard of care at the study hospital (Parkland Hospital in Dallas, Texas) and other hospitals nationwide.
Vegetarian and vegan diets have been shown to reduce cardiometabolic risk factors for chronic diseases, such as cardiovascular disease and diabetes, and have been associated with decreased risk of these chronic diseases. The role of vegetarian and/or vegan dietary patterns and incident cardiovascular outcomes still remains unclear. To address these uncertainties, the investigators propose to conduct a systematic review and meta-analysis of the totality of evidence from prospective cohort studies to distinguish the association of vegetarian and/or vegan dietary patterns on the prevention and management of cardiovascular diseases. This proposed knowledge synthesis was commissioned by the Diabetes and Nutrition Study Group (DNSG) of the European Association for the Study of Diabetes (EASD) and will be used to inform clinical practice and dietary guidelines, help improve health outcomes, and guide future research design.
Dyslipidemia is an independent risk factor for cardiovascular events. Statins have become the cornerstone for the prevention and treatment of atherosclerotic vascular diseases. However, after the comprehensive control of the traditional risk factors, including unhealthy lifestyle, hypercholesterolemia, hypertension, hyperglycemia and obesity, there is still a high risk of residual cardiovascular disease in patients with dyslipidemia. Triglyceride elevation is the most common type of dyslipidemia and constitutes an important component of cardiovascular residual risk. The geraniol has a variety of pharmacological effects, such as anti-inflammatory, antioxidant, regulating cell apoptosis. Recent studies have confirmed that geraniol plays an important role in regulating glucose and lipid metabolism, and may have a synergistic role with statins. Gefarnate Tablets is a kind of anti-ulcer and gastritis treatment. It can increase the defense ability of gastric mucosa by improving the prostaglandin level and the concentration of amino hexose in the gastric mucosa. Geraniol is the main components of Gefarnate Tablets. In the previous study, the investigators found that geraniol induced autophagy through the SIRT1-AMPK-mTOR pathway and accelerated the degradation of triglycerides in liver cells, thus reducing the level of triglyceride in the serum of high fat diet mice. 6 patients with hyperlipidemia were received Gefarnate Tablets (100mg/ times, 3 times per day). A month later, the levels of serum triglyceride, total cholesterol, and low density lipoprotein cholesterol were decreased significantly. However, the above results need to be confirmed by the larger clinical research. Therefore, the aim of this study is to evaluate the effect of Gefarnate Tablets on blood lipid levels in patients with hypertriglyceridemia and coronary heart disease treated with statins, provide more options for the treatment of lipid lowering treatment, reduce the risk of cardiovascular remnant, and improve the long-term prognosis of the coronary heart disease patients with residual hypertriglyceridemia.
• The aim of the VIP study is to investigate the impact of vulnerability markers (inflammatory serum biomarkers for systemic vulnerability, coronary shear stress and vulnerability mapping for pancoronary vulnerability, and imaging-based plaque features for systemic vulnerability) on the rate of major adverse cardiovascular events caused by progression of the non-culprit lesion in patients with acute ST or non-ST segment elevation myocardial infarction who undergo revascularization of the culprit lesion during the acute event. Furthermore, the study will evaluate the rate of progression of non-culprit lesions towards a higher degree of vulnerability, based on coronary computed tomography angiographic assessment at 1 year after enrollment.
The primary purpose of this study is to evaluate whether treatment with oral anticoagulation or oral anticoagulation and aspirin is better than aspirin alone in cardiovascular outcomes and saphenous graft patency in patients submitted to coronary artery bypass graft.
