Active clinical trials for "Myocardial Ischemia"

This study is a prospective, multi-center single arm registry trial, planning to enroll 785 subjects. All subjects will receive clinical follow-up at 1 month, 6 month, 9 month and 1, 2, 3, 4, 5 year after index procedure. The primary endpoint will be target lesion failure (TLF) at 1 year after index procedure,which will be analyzed to evaluate the efficacy and safety of the device.

Greater diagnostic accuracy is required to find out who is at risk of a heart attack as this can reduce the requirement of more invasive downstream tests and thereby improve the patient experience and also reduce their exposure to risk. Stress echocardiography is a routine clinical test that involves using ultrasound to image the heart whilst it is under stress to assess the risk of a heart attack. This study will focus on developing more accurate analysis tools to interpret the results of these stress echocardiographic scans. New methods will be tested to measure the function of each part of the heart muscle, using advanced analysis of the information obtained when high-frequency sound waves are bounced off the heart inside the chest. The researchers will measure and report exact heart function during stress, so that they will be able to recognise normal hearts and those with any disease. New computer methods will be developed to display any abnormality, which will make it easier for doctors to choose the best treatment for patients who are at risk. The goals and potential benefits of this research proposal are to update the interpretation of a routinely used clinical test (stress echocardiography) to produce a reliable new method for diagnosing the precise effects of diseased arteries on the function of the heart muscle; to develop new computer graphics that adapt to show individual risks for each patient; and to implement new computer models that can be constantly updated

To evaluate the long-term clinical outcomes and prognostic factors in patients with coronary artery disease undergoing coronary artery bypass graft surgery. To evaluate the long-term clinical outcomes and prognostic factors in patients with coronary artery disease undergoing percutaneous coronary intervention with drug-eluting stent.

Evaluation of outcomes of coronary artery bypass grafting.

Patients with multivessel coronary disease have a compromised blood flow in the hearts own vessels, due to stenoses, and they are often treated with a coronary artery bypass grafting surgery. This is a big heart operation where the sternum (breast plate) is split and the heart is once again given a sufficient blood flow, by redirecting blood to the compromised areas through grafts. Another method for treating coronary disease is with percutaneous coronary intervention, or an endovascular approach that can re-establish blood flow to the hearts vessels by lessening the stenoses. However, bypass surgery is still the treatment of choice when there are multiple vessels in the heart with significant disease. In this trial we want to examine if a less invasive approach, called hybrid revascularization, where we combine the best of both treatments is better than the current standard. The combination is a minimally invasive bypass surgery, called MIDCAB which makes a bypass graft through a key-hole surgery for the anterior vessel on the heart, and catheter treatment of all other vessels with significant stenoses. We will compare the hybrid revascularization with the conventional treatment with a full bypass surgery through a sternotomy. Our hypothesis is that a less invasive revascularization strategy gives a better clinical outcome than the current standard with coronary artery bypass surgery through a split sternum. To test our hypothesis we will conduct a multicenter randomized clinical trial.

The objective of this study is to evaluate safety and effectiveness of the SINOMED CBC coronary dilatation catheter during PCI in subjects with stenotic coronary arteries.

This study sought to assess the diagnostic and prognostic values of metabolomics in coronary artery disease(CAD).

Introduction: Today it is necessary to emphasize that coronary heart disease is often associated with anxiety disorders. Research over the years has shown several and sometimes surprising links between coronary heart disease and mental illness, and has even suggested that both of these phenomena may actually cause each other. However, the exact nature of these links has not yet been clearly established. Methods: The study included 202 patients with coronary artery disease, of whom 42 patients were with stable angina pectoris, they participated as a control group, and 160 patients with unstable angina pectoris, who made up the main group. Among them there are 102 women and 100 men between the ages of 30 and 88. The average age was 63.75 ± 11.37 years. All study participants had blood in the morning on fasting after 8-12 hours of fasting from the cubital vein. Determination of the level of cytokines TNF-α, IL-1β, IL-4 and IL-10 in blood serum by enzyme-linked immunosorbent assay (ELISA). All participants in the study had blood drawn in the morning on fasting after 8-12 hours of fasting from the cubital vein. The level of uric acid was determined on the CYAN Start apparatus using a unified method. When examining patients with unstable angina pectoris were used: hospital anxiety and depression scale [Kozlova S.N. 2013]. And also the Spielberger-Khanin scale [Psychiatry - Hoffman A.G. 2010], developed by Spielberger Ch.D. and adapted by Yu.L. Khanin. to assess cognitive functions [Psychiatry - Gofman A.G. 2010].

Multidisciplinary team-approach in order to offer personalized treatments represents the emerging mainstream in cardiovascular medicine. "Hybrid operative rooms" allow to offer selected heart-disease patients truly "tailored" operations. This study wants to evaluate the effectiveness and safety of Hybrid Procedures in cardiac patients in three subgroups of patients: Hybrid coronary revascularization strategy (coronary by-pass + PCI); Hybrid valve and coronary disease correction (combination of surgical valve replacement and PCI); Hybrid coronary and carotid artery disease treatment (combination of coronary by-pass and carotid stenting). The investigators hypothesize that morbidity might be reduced by 50% in hybrid procedures group as compared with predicted Society of Thoracic Surgery (STS) score.

Our study focuses on the question about primary cardiac rehabilitation (CR) patients with coronary heart disease are concerned about demonstrating the association between the patients' view of CR and social associated factors. In our study, all participants are invited to choose at least 1 question in 15 questions or provide their questions regarding their doubt about the CR after filling in their personal information. The selectable questions can be categorized into five titles: the content or purpose of CR, the method of CR, the advantage of CR, the adverse effect of CR, and the expenditure of CR.
