Filter by:To determine whether hemodynamic support combining VA-ECMO with IABP could mitigate the rates of Major Adverse Cardiovascular and Cerebrovascular Events (MACCEs), compared with IABP support alone, in patients undergoing elective and high-risk PCI.
We hypothesized that periodontal disease and edentulism could be a risk for CAD and there might be a relationship between the oral status and the number of main coronary vessels with ≥ 50% stenosis. Therefore, primary goal of this study is to investigate the connection between oral status and the extent of coronary artery disease (CAD), which is diagnosed by angiography.
This is a multicenter, prospective trial to measure the test performance characteristics of the Magnetocardiography (MCG) CardioFlux cardiac diagnostic system in detecting clinically significant coronary artery obstruction in patients with symptoms of suspected acute coronary syndrome or who present with a failed stress test with the intention of treat with cardiac catheterization.
68Ga-DOTATATE is a PET radiotracer with high affinity and selectivity for somatostatin receptor 2 (SSTR 2) and is approved clinically for the evaluation of patients with neuroendocrine tumors. The SSTR2 receptor is also highly expressed at the surface of human macrophages and lymphocytes. In comparison to FDG, 68Ga-DOTATATE presents the advantage of fast clearance from tissues, which are not expressing somatostatin receptors, in particular muscular and myocardial tissues, and the level of blood glucose does not influence its uptake. Accumulation of 68Ga-DOTATATE has already been detected in coronary and carotid plaques and is associated with the number of activated macrophages present in plaques obtained after carotid endarterectomy. In a recent study, Tarkin et al. confirmed the preferential uptake of 68Ga-DOTATATE by macrophages in atherosclerotic plaques. In addition, the intensity of 68Ga-DOTATATE was higher in culprit lesions in the carotid and coronary arteries than in stable lesions. The evaluation of 68Ga-DOTATATE uptake in coronary arteries was also strongly facilitated in comparison to FDG thanks to the absence of spillover signal from the myocardium. AAA has developed a new kit that has markedly simplified the synthesis of 68Ga-DOTATATE and has obtained in the US marketing authorization for the kit (Netspot; kit for the preparation of Gallium-68-DOTATATE injection for intravenous use) on June 1st 2016 (NDA 208547) for evaluation of patients with neuro-endocrine tumors. The Netspot kit will be used in this study for the detection of progressing coronary atherosclerosis.
Study type: prospective cohort and randomized trial. Duration: estimated 2 years. Indications: Type II myocardial infarction in critically ill patients. Purpose: 1. To recognise the incidence of type I myocardial infarction (MI) in patients with suspected type II MI. 2. Determining the safety of early coronary angiography in this population. 3. Assessment of the effect of percutaneous coronary revascularization in critically ill patients with stable obstructive coronary disease and type II MI. Hypotheses: 1. Obstructive coronary artery disease suitable for percutaneous revascularization is present in majority of patients with type II MI. 2. Type I MI (acute coronary artery thrombosis) is present in some patients and not recognised. 3. Echocardiogram and a 12-lead electrocardiogram are not reliable in predicting coronary artery disease. 4. Urgent invasive diagnostic is safe in patients with type II MI. 5. Percutaneous revascularization (if indicated) reduces the size of myocardial necrosis in patients with type II MI. Objectives: - Primary endpoint: to demonstrate that percutaneous coronary intervention (PCI) in the group with obstructive coronary disease reduces the size of MI. - Secondary endpoints: improved cardiac function after revascularization, shorter hospitalization, reduced mortality. - Safety objective: renal function, bleeding complications. Population: 140 patients with type II MI over 18 years of age with no evidence of active bleeding. Inclusion criteria: - age> 18 years - High sensitive troponin I > 40 ng / L for women and > 58ng / L for men - Critical illness (at least one vital organ support) - Imaging signs (electrocardiogram or ultrasound) signs of myocardial ischemia Exclusion criteria: - active bleeding - terminal illness Monitoring of patients: during hospitalization, 30 days after discharge, 6 months after discharge. Performance check: - PCI success (% of "thrombolysis in myocardial infarction" flow 3) - the size of MI (troponin area under the curve) - left ventricular ejection fraction - hospital stay - 30 day survival Safety Check: - monitoring of renal function - monitoring of bleeding complications - monitoring of allergic reactions to contrast and medication Patient Consent: written informed consent for inclusion in the study in conscious population. In unconscious patients, written consent will be obtained in the event of mental function improvement.
The objective of this research proposal is to find out whether comparing the two different anaesthetic maintenance techniques (Propofol vs volatile anaesthetics) in adult patients undergoing heart surgery is practical for the anaesthetist treating the patients and whether it is feasible for the research team to recruit patients and follow them up after the operation.
The investigators sought to investigate the prognostic implication of qualitative and quantitative plaque analysis on coronary CT angiography (CCTA) according to fractional flow reserve (FFR). The main objective was to develop a comprehensive risk model by using clinical risk factors, FFR and CCTA parameters.
The primary objective of this study is to build a repository of resting cardiac phase space signals from eligible subjects using the Phase Signal Recorder (PSR) prior to coronary angiography for the purposes of machine-learning and testing algorithms developed by Analytics 4 Life. Male and Female subjects will be uniquely and consecutively enrolled into one group to support populating a repository of phase signals.
This additional arm of the DESolve Nx study is an evaluation of the CE Mark approved DESolve Cx Novolimus Eluting Bioresorbable Scaffold System.
Single-centre prospective cohort study of patients presenting with severe limb ischaemia (SLI). The primary outcome measure will be 12 month major amputation rate. A historical cohort of patients identified retrospectively will be the comparitor group used to assess the impact of a newly-established rapid-access limb salvage clinic. Primary aim: - Determine the proportion of patients with SLI undergoing major lower limb amputation within 12 months of presentation. Secondary aims: - Assess clinically important short-, medium- and long-term outcomes in those undergoing and not undergoing amputation - Prevalence and degree of frailty and cognitive impairment - Pevalence and degree of cardiac disease (detected by stress MRI) - Establish a biobank for future biomarker analysis - Investigate the role of frailty and cognitive assessments, cardiac MRI and biomarkers in risk-stratification of patients with SLI
