Filter by: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.
An accepted "gold standard" for hemodynamic monitoring in women with both healthy and diseased hearts is not currently available. Pregnancy is associated with significant hemodynamic changes, both during and following delivery, which can be even more profound in the structurally-abnormal heart. Clinical management of these women is based on surrogate markers of cardiac indices such as peripheral blood pressure, heart rate and oxygen saturation, rather than the use of invasive testing due to its associated complications. Echocardiography has largely replaced PAC in the obstetric population to measure cardiac output due to its non-invasive nature and good correlation with PAC18. However, its use is limited in the intrapartum period due to the need for clinical expertise in obtaining and interpreting the images. The proposed study has the potential to validate bio-reactance cardiac output monitoring using the NICOM against echocardiography for use in structurally normal and abnormal pregnant hearts in order to better drive goal-directed (specifically delivery mode) therapy through continuous hemodynamic monitoring during the second and third stages of labor, and 24 hours postpartum.
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.
The erector spinae plane block is a novel regional anesthetic technique that allows for analgesia of the thorax and abdomen with a peripheral nerve block. The goals of this study are to determine if bilateral erector spinae plane blocks (ESPB) after sternotomy for congenital heart repair in high risk children and adults can decrease outcomes such as duration of postoperative mechanical ventilation (MV), perioperative opioid consumption, days in the intensive care unit (ICU) and length of stay (LOS).
The objective of this study is to assess the safety and initial effectiveness of the TIVUS™ System when used for pulmonary artery denervation in group II PH patients through change in clinical parameters including hemodynamics, exercise tolerance, and quality of life. This is a prospective, multi-center, non-randomized, open-label clinical trail. The study will be conducted in up to 3 centers and will recruit up to 15 patients diagnosed with pulmonary hypertension due to left heart disease that demonstrate combined pre and post capillary involvement with PVR>3 wood units.
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 proposal of this study is to verify if it is feasible and effective to offer a home based cardiac rehabilitation program, that includes the components of health education and physical exercises mostly unsupervised and oriented by telephone and to compare the treatment adherence, the effects in the functional capacity, and the control of coronary risk factors in relation to the traditional cardiac rehabilitation offered mostly supervised and center based.
In this clinical study the investigators will compare blood pressure measurements obtained using the non-invasive, continuous and wireless Biobeat monitoring device (a wrist watch or a patch configuration) to an invasive arterial line (radial or femoral) in 30 patients immediately after cardiac surgery, at the intensive care unit.
