Active clinical trials for "Myocardial Ischemia"

Assessment of Change in AtheROSclerotic Plaque by Serial CCTA (ACROSS) is designed as a prospective observational study which aim is to demonstrate the effect of statins on coronary atherosclerosis, assessed by quantitative analysis of CCTA.

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.

Myocardial protection is of crucial importance for surgical coronary revascularization in patients with ischaemic heart diseases. The investigators proposed loop isolation-based uploading preconditioning to protect heart from ischemic-reperfusion damage (LiuPhD) as a novel cardioprotective strategy, and applied to patients who underwent on-pump coronary artery bypass grafting (CABG).

This is a cross-sectional and follow-up study. We analysis the relationship of sleep quality on coronary artery disease(CAD) and in stent restenosis(ISR). Further, we explore the mechanism of relationship between the sleep quality and CAD/ ISR by examining the biomarkers in the pathway of sleep-CAD/ISR.

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 the Dietary Approaches to Stop Hypertension (DASH) diet, a dietary pattern that emphasizes fruits and vegetables, low-fat or non-fat dairy, limiting saturated fat intake and usually also recommends limiting sodium intake. To update the recommendations, the Diabetes and Nutrition Study Group (DNSG) of the EASD commissioned an umbrella review of systematic reviews and meta-analyses using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach to summarize the available evidence from recent systematic reviews and meta-analyses of prospective cohort studies and randomized and non-randomized controlled trials of the relationship between the DASH dietary pattern and cardiometabolic risk.

Coronary artery disease (CAD) is a major cause of death and disability in developed countries.Human studies revealed a significant association between serum oxidative status using PON1, TBARS and thiol levels and the presence of CAD and its severity. However, these studies were addressing the severity of CAD depending on coronary angiography of patients presenting with ST elevation myocardial infarction, Non ST elevation myocardial infarction, unstable angina pectoris, while part of them even had a history of CAD. Others where admitted for an elective coronary angiography for suspected stable CAD while only few patients were assessed for atypical chest pain. This study thus aims to assess the relationship between PON1 activity, TBARS and thiol levels and the existence of CAD and its severity in patients with no previous history of CAD presenting to the emergency department (ED) with acute chest pain but with no evidence of acute myocardial infarction or acute E.C.G ischemic changes. Assessment with a Cardiac CT scan instead of coronary angiography will allow the investigators to study the status of coronary atherosclerosis and calcium burden in all participants, including those presenting with atypical chest pain that most probably will not be referred by physicians to a coronary angiography. Further sub groups analysis will estimate this relationship particularly in low-intermediate risk groups depending on 3 different validated scoring systems - TIMI, GRACE and HEART score.

Blood transfusion is an expensive and finite resource and optimum transfusion threshold in surgical patients is yet to be defined. Patients commonly receive blood transfusions to reduce the risk of myocardial ischaemia or improve perfusion of other organs (e.g. the kidneys), but this treatment may have important adverse effects including postoperative infection. Patients undergoing surgery for fractured neck of femur are often elderly, with co-morbidities and a high risk of postoperative complications, including MI and AKI. We propose to conduct a study with the following aims: To describe the incidence of anaemia and transfusion in patients undergoing surgery for fractured neck of femur. To use clinical and biochemical data to measure the incidence of perioperative cardiac and kidney injury in this group. To evaluate highly sensitive serum troponin and urinary MALDI-MS as possible endpoints in a future prospective randomised trial of perioperative transfusion.

Background: The human gastrointestinal system is populated with a variety of symbiotic microorganisms, namely microbiota. The microbiome is the total genetic data of the microbiota. The human gut microbiota interacts extensively with the host through metabolic exchange; thereby contribute to a variety of metabolic and immunologic mechanisms in the human body. Coronary artery disease (CAD) is major cause of morbidity and mortality worldwide and is a major field of interest in microbiota research. There have been several findings that connect the gut microbiota to CAD pathophysiology, but these data relates solely to the interaction between human gut microbiome and cardiovascular risk factors. As far as known , data regarding patients who already developed CAD is lacking. Aims: To investigate gut microbiota of patients with CAD, thereby allowing the adjustment of personalized treatment by changing the pro-atherosclerotic environment in the gut. Methods: Study participants will include patients arriving to Rabin Medical Center with suspected CAD. Patients will provide medical, lifestyle, and nutritional questionnaires. Vital signs measurements will be taken as well as fecal samples and/or rectal swabs. Blood samples will be drawn to measure blood chemistry including lipid profile and trimethylamine-N-oxide (TMAO) levels. Patients will undergo cardiac CT and/or cardiac catheterization in accordance with the decision of the cardiologist to evaluate and/or treat CAD. Genomic DNA will be extracted from stool samples for Microbiome analysis. Innovation: The hypothesis is that there is a unique microbiota pattern in patients with coronary atherosclerosis, which may contribute to the pathogenesis and/or expression of CAD. Knowing the unique microbiota in patients with coronary disease, would render it as novel target for treatment, either primary or secondary prevention. Collaboration: Between Cardiology department at Rabin Medical Center and the lab of Prof. Eran Segal located at the Weizmann Institute of Science. The collaboration between these two groups will combine the clinical expertise of treating cardiac patients with novel scientific technology and concept.

The purpose of this study is to determine whether text messages/messaging (TM) or a mobile application (app), compared with an educational website-control provided to all Veterans, can improve adherence to antiplatelet therapy among patients following acute coronary syndrome or percutaneous coronary intervention (ACS/PCI).
