Active clinical trials for "Myocardial Ischemia"

This study was advocated by institute of Basic Research in Clinical Medicine,China Academy of Chinese Medical Sciences in October 2011. It was funded by China major scientific and technological specialized specialized project for 'significant new formulation of net drugs'. Kudiezi(Yueanxin) is kind of Chinese Medicine injiection used for treating corinary heart diswese、angina pectoris and stroke in many Chinese hospitals. The purpose of this study is to determine adverse drug events or adverse drug reaction in large sample size 30,000 patients.

The purpose of the study is to identify a sub-group of diabetic patients at higher risk of progression of coronary disease and also more likely to suffer from heart attack/angina and heart failure. The total number of patients to be recruited in this study will be 250 with type-2 diabetes but no known heart disease. These patients will have an objective measure of the function of the lining of the arteries, CT scan of the arteries of the heart and an ultrasound scan of the heart and arteries of the neck done at baseline along with blood tests for identification new markers of malfunction of the lining and inflammation of the arteries. Patients will be followed up at 18 months. During the follow-up visit, in addition to the blood tests, the CT scan of the heart arteries and ultrasound of the heart and arteries of the neck will be repeated to assess progression of the non-calcified, calcified and mixed plaques in the coronary arteries.

There is currently no published algorithm for secondary prevention prognosis of CHD that is representative of the England GP-registered population and that includes both symptomatic and asymptomatic patients (as identified through primary care). In this paper the investigators will exploit routinely collected information in clinical practice to model CHD prognosis based on a large contemporary open cohort of stable CAD patients. Although the investigators model is based on data from GP practices in England only, the investigators believe that this population is sufficiently heterogeneous in terms of ethnic mix, socioeconomic background, predisposing characteristics and lifestyles to generate a prognostic model with good generalizing power to the wider population. Among the research questions the investigators will try to answer is whether established risk factors for primary care prevention (smoking, hypertension, dyslipidaemia, diabetes) are also reliable for risk-stratification of patients who have already developed CAD. Similarly, the investigators will examine whether strong predictors of adverse outcomes in ACS patients in the short term, such as admission SBP and heart rate, are also associated with their long term prognosis.

This study was advocated by Institute of Basic Research in Clinical Medicine, China Academy of Chinese Medical Sciences in October 2011. It was funded by China major scientific and technological specialized project for 'significant new formulation of new drugs'. Shenfu is kind of Chinese Medicine injection used for treating shock and coronary heart disease in many Chinese hospitals. The purpose of this study is to determine adverse drug events or adverse drug reaction in large sample size 20,000 patients.

The purpose of this study is to make a cohort event monitoring to see whether and how Shenmai injection in hospital results in adverse events or adverse drug reactions.

The objectives of this study are To establish a prospective registry of the whole patients who received percutaneous coronary intervention with Resolute Onyx™ stent. To evaluate the long-term efficacy and safety of coronary stenting with the Resolute Onyx™ stent. To compare the long-term efficacy and safety of coronary stenting between the Resolute Onyx™ stent and other contemporary drug-eluting stents which had established their own registry.

Assessment of the clinical safety and performance of the Orsiro drug-eluting stent in a real world setting in patients with small vessels with reference vessel diameter ≤2.75 mm.

The European Association for the Study of Diabetes (EASD) guidelines have not made any specific recommendations regarding dietary pulses. To update the recommendations, the Diabetes and Nutrition Study Group (DNSG) of the EASD commissioned an umbrella review and updated systematic review and meta-analysis using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach to summarize the available evidence from prospective cohort studies of the association between dietary pulses/legumes and cardiometabolic disease outcomes (incident cardiovascular diseases, diabetes, hypertension and overweight/obesity).

Fruit and vegetables are a cornerstone of healthy dietary patterns and dietary guidelines worldwide. The supporting evidence, however, is largely derived from observational studies of protective associations with cardiovascular disease (CVD) in health-conscious populations or from randomized trials of the effect of specific fruit or vegetable derived nutrients on CVD risk factors. A growing body of literature has influenced a shift away from a focus on single nutrients to a focus on whole foods and dietary patterns. To what extent fruit and vegetables should contribute to dietary patterns for cardiovascular health and whether specific types of fruit or vegetables should be recommended is unclear. Although previous systematic reviews and meta-analyses have elucidated the association between the intake of total and some specific fruit and vegetables with cardiovascular outcomes, a comprehensive synthesis comparing the certainty of the evidence for the different types of fruit and vegetables in relation to a range of cardiovascular outcomes has yet to be completed. We propose to conduct a systematic review and meta-analysis of the available prospective cohort studies using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach to assess the association between different types of fruit and vegetables and different cardiovascular outcomes that include CVD, coronary heart disease [CHD], and stroke incidence and mortality.

Coronary chronic total occlusions (CTOs) are defined as an occluded coronary vessel with TIMI defined as an occluded coronary vessel with TIMI (Thrombolysis in Myocardial Infarction) grade flow 0 and an estimated duration of at least 3 months. They are frequently encountered in patients undergoing coronary angiography. The application of contemporary techniques and the use of advanced dedicated equipment lead to high procedural success and low adverse events rates in experienced centers. Fractional flow reserve (FFR) is a validated tool to assess physiological severity of coronary artery disease and have a prognostic role after percutaneous coronary intervention (PCI). SPECT (Single-Photon Emission Computed Tomography) is the golden standard for detection of myocardial ischemia. Recanalization of a CTO leads to a number of anatomical and pathophysiological changes to the coronary circulation. These include anatomical and functional collateral vessels regression and significant lumen enlargement because of recovery of blood flow and restoration of vasomotor tone. The effect of PCI on CTO is unknown. The aim of this study was to assess the functional result of CTO PCI by measuring FFR and D SPECT before and immediately post-CTO PCI and at short-term follow-up.
