To observe the effects of fastigial nucleus stimulation on serum inflammation, oxidative stress related factors, cardiac autonomic function and prognosis in patients with coronary heart disease
It has been assumed that some elements of the ERAS protocol may contribute to the reduction of complications and improve the satisfaction of patients undergoing coronary artery bypass surgery. Elements of the ERAS strategy will be tested in this study. The elements that prove to be feasible and have a positive effect on the treatment process will be introduced into everyday clinical practice. In the next stage of the research, we are planning to investigate whether the introduction of the ERAS strategy has had a long-term positive effect on the quality of life after treatment (a survey 1 month and 6 months after leaving the hospital).
Remote ischemic conditioning(RIC) is a protective systemic strategy by organs brief and sublethal ischemia to confer protection from subsequent severe ischemia in distant organs, especially for heart and brain. This study will discuss whether RIC can play a part in preventing the patients with coexistence of cerebral and coronary atherosclerosis from the recurrence of cerebral vascular disease(CVD) or coronary artery disease(CAD). This study selects patients who suffered an ischemic stroke within 14 days prior to enrollment. All patients complete cerebral and coronary artery assessment. And then the the investigators select the patients who both have at least one cerebral vascular and at least one coronary artery stenosis over 50%, or the patients who both have at least one cerebral vascular stenosis over 50% and myocardial ischemic events history. These patients will randomly divide into two groups, RIC group and non-RIC group. Non-RIC group will only accept cardio-cerebrovascular disease secondary prevention treatment. RIC group will use not only cardio-cerebrovascular disease secondary prevention treatment, but also RIC everyday for three months, 5 cycles 5min ischemic-5min reperfusion each day. For the first month, the the investigators will call RIC group patients every week for insuring compliance and adverse effect. All patients will follow up endpoint events, cardio-cerebrovascular disease secondary prevention treatment, and the adverse effect every three months, up to one year.
EVAREST will identify and validate novel blood and imaging biomarkers of potential value for consistent and accurate interpretation of stress echocardiography. During phase one, blood samples will be collected to assess the impact of cardiac stress on levels of circulating biomarkers and examine whether the measurement of these biomarkers can provide additional prognostic information. Phases one, two and three will also determine whether novel imaging biomarkers can be identified in the echocardiograms that can be used for objective interpretation of the stress echocardiograms. EVAREST will recruit up to 8000 patients (First 500 during phase one, an additional 500 during phase two and an additional 7000 during phase three) from multiple hospitals across United Kingdom, who have been referred for a stress echocardiogram as part of their investigations into ischaemic heart disease. Phase four of the study will continue into a clinical study cohort phase to capture information from all patients referred for a stress echocardiogram in the UK, regardless of the reason for investigation.This registry phase will run for 2 years, recruiting up to 15000 participants.
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 purpose of the study: to increase the efficiency of diagnosis, treatment and prediction of the course of coronary heart disease in patients with adenocarcinoma of the prostate gland, depending on the hormonal status by determining the cardiovascular risk factors, factors of angiogenesis, structural and functional state of the heart, coronary vessels, kidney damage and their pharmacological correction.
The purpose of this study is to investigate the effect of percutaneous coronary intervention (PCI) on cardiac function in multi-vessel disease patients with concurrent chronic total occlusion (CTO) lesion.
Coronary Computed Tomography Angiogram (CCTA) is a non-invasive imaging modality that has high sensitivity and negative predictive value for the detection of coronary artery disease (CAD). The main limitations of CCTA are its poor specificity and positive predictive value, as well as its inherent lack of physiologically relevant data on hemodynamic significance of coronary stenosis, a data that is provided either by non-invasive stress tests such as myocardial perfusion imaging (MPI) or invasively by measurement of the Fractional Flow Reserve (FFR). Recent advances in computational fluid dynamic techniques applied to standard CCTA are now emerging as powerful tools for virtual measurement of FFR from CCTA imaging (CT-FFR). These techniques correlate well with invasively measured FFR [1-4]. The primary purpose of this study is to evaluate the incremental benefit CT-FFR as compared to CCTA in triaging chest pain patients in emergency settings who are found to have obstructive CAD upon CCTA (generally >= 30% stenosis). Invasive FFR and short term clinical outcomes (90 days) will be correlated with each diagnostic modality in order to evaluate positive and negative predictive value of each. Patients will undergo a CCTA, as part of routine emergency care. If the patient consents to participate in the study, the CCTA study will be assessed by Toshiba Software, to provide a computerized FFR reading, based on the CCTA study. If the noninvasive FFR diagnosis indicates obstructive disease, the patient will undergo cardiac catheterization with invasive FFR. As CCTA utilization increases, the need to train additional imaging specialists will increase. This study will assess the capability of FFR-CT to enhance performance on both negative and positive predictive value for less experienced readers by providing feedback based on CT-FFR evaluation. If the use of CT-FFR improves accuracy of CCTA, as compared to the gold standard, (Invasive FFR), use of CT-FFR can potentially enhance performance for less experienced readers.
The coronary images of selective angiography and optical coherence tomography with FFR(Fractional Flow Reserve) values of the intermediate lesions (40-70% stenosis) will be prospectively registered.
