Filter by:This is an European prospective cohort study from February 2023 until February 2024. The investigators want to analyze the clinical success, efficacy and safety of consecutive patients who presented with ST-elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI) for de novo heavily calcified culprit lesion using plaque modification devices before stent implantation.
The goal of this prospective study is to evaluate the role of cardiovascular magnetic resonance (CMR) in patients with suspected non-ST elevation myocardial infarction (NSTEMI). The main endpoint is the reclassification rate, defined as the number of patients in whom the information provided by pre-angiography CMR affects the revascularization strategy or the final diagnosis. Participants will undergo to CMR before invasive coronary angiography (ICA).
Among patients early following ST-segment (ST) elevation myocardial infarction, transcutaneous vagus nerve stimulation is associated with a reduce of the burden of premature ventricular contractions in the first 40 days post-myocardial infarction (MI). The above hypothesis will be tested with a randomized, prospective, parallel, single-blind clinical trial. The expected study duration is approximately 12 months from the time the first subject is enrolled (planned for June 2023) to the time of study's termination date (December 2024). Patient enrollment is planned to take place at two major centers in Greece. The researchers will obtain approval by the institutional review board (IRB).
Cardiac troponin is central to the diagnosis of myocardial infarction and high-sensitivity cardiac troponin (hs-cTn) assays are the preferred choice for the assessment of patients with suspected acute coronary syndrome. Since the introduction of hs-cTn assays in Europe in 2010, most hospitals have switched from contemporary sensitive cardiac troponin assays to a hs-cTn assay. The implementation of hs-cTn assays has led to an increase in the number of patients identified with myocardial injury. Although both hs-cTnI and hs-cTnT assays are recommended in current guidelines, the impact of switching from a hs-cTnI assay to a hs-cTnT assay on clinical practice is unknown. At this point, no studies have evaluated the impact of implementing sex-specific hs-cTnT thresholds on the diagnosis of myocardial infarction and outcome in clinical practice. The investigators propose to determine the proportion of patients with and without myocardial injury admitted to the hospital before and after implementation of a hs-cTnT assay and to evaluate the impact on investigations, care and clinical outcomes in consecutive patients with suspected acute coronary syndrome.
Study of role of colchicine in reducing periprocedural myocardial injury in patients prepared for elective PCI and its role in reduction of MACEs.
The purpose of this study is to demonstrate the effectiveness and safety of CVA-FLOW, a digital health AI based Telestroke system developed by CVAID Ltd. Company aims to assist certified medical staff to triage acute ischemic stroke patients using dedicated algorithms in order to support application for market approval for CVA-FLOW device.
Despite the use of guideline directed optimal medical therapy, 12% of patients with stable coronary heart disease and 18% of patients with recent acute coronary syndrome experience recurrent major adverse cardiovascular events 1. The risk of recurrent cardiovascular events may be related to persistent elevation of thrombin beyond the index event 2,3 which leads to progression of cardiovascular disease by inducing inflammation, endothelial dysfunction and thrombosis 4. In patients with coronary heart disease, vitamin K antagonists (VKAs) and direct oral anticoagulants (DOACs) have been explored as secondary prevention strategies and have shown cardiovascular benefits at the cost of higher bleeding events 5,6,7,8. howeverLeft ventricular thrombus (LVT) usually appearswithin 1 month after ST-segment elevation myocardial infarction (STEMI) and mostlyforms after anterior STEMI.9,11Although the prevalenceof LVT after acute myocardial infarction hasdecreased dramatically in modern times due to the progress of reperfusion therapy, LVT incidence in patients with anterior STEMI remains at 4% to 26%.10,12 It complicates acute myocardial infarction and is associated with a higher incidence of poor outcomes.9
A single center, prospective, observational study to compare fractional flow reserve (FFR) and intravascular ultrasound (IVUS) percutaneous coronary intervention (PCI) optimization strategies on the functional PCI result (assessed with FFR) immediately post PCI and at 9-12 months after the treatment of long coronary artery lesions.
Dual Antiplatelet Therapy (DAPT) with acetylsalicylic acid (ASA) and oral P2Y12 inhibitor (Clopidogrel, Ticagrelor or Prasugrel) is recommended in STEMI or NSTEMI patients undergoing primary Percutaneous Coronary Intervention (PCI). There is evidence for an increased risk of stent thrombosis after PCI despite administration of DAPT in patients resuscitated from a cardiac arrest with STEMI/NSTEMI who undergo primary PCI, in particular for those treated with hypothermia. Point of Care Aggregometry represents an emerging tool to measure platelet reactivity in patient treated with antiplatelets drugs. Among patients with Acute Coronary Syndrome (ACS), those requiring Veno-Arterial Extracorporeal Membrane Oxygenation (VA-ECMO) for refractory Cardiogenic Shock or Cardiac Arrest represent a growing population burdened by more profound metabolic, pharmacokinetic, hemostatic and physiological alterations due to increased clinical severity and ECMO itself. In addition, profound platelet inhibition can result in a higher risk of bleeding complication, since these patients have to be simultaneously anticoagulated with unfractioned heparin (UFH) and ECMO itself can cause coagulopathy. We aimed to perform an observational prospective cohort study to investigate platelet reactivity in a population of ACS patients with different clinical severity.
The present study seeks to evaluate the effectiveness of the use of perioperative colchicine with regard to operative complications, in patients with acute coronary syndrome and indication for cardiac post-surgical revascularization. Patients will be selected and randomized while still in the emergency room and medication (colchicine 0.5mg every 12 hours or placebo) will be started within 24 hours of randomization, being maintained for 30 days after surgery.
