Acute Coronary Syndrome:Non ST Elevation Myocardial Infarction2 more

The administration of these drugs is realized according to the European Society of Cardiology guidelines. All patients will be pretreated with aspirin 300 mg orally, heparin iv to maintain an activated clotting time of >250 sec, and a loading dose of ticagrelor (180 mg) or clopidogrel (600 mg) immediately before the revascularization. The list of assignment to ticagrelor or clopidogrel will be generated by a computer according to a 1:1 randomization. Primary Percutaneous Coronary Intervention will be performed according to standard clinical practice using femoral or radial artery Judkins approach via six or seven French heath insertion. After crossing the target occlusive Lesion, coronary stenting will be performed based on standard practice. Patients subsequently will receive heparin for 48 hr, aspirin 100 mg daily, and clopidogrel (75 mg/day) or ticagrelor (90 mg twice daily) for at least 12 months. Other adjunctive pharmacotherapy in Intensive Care Unit will be administered according to operator discretion. All patients will provide written informed consent before entering the study. Before and after the procedure a 12-leads ECG and an echocardiogram will be performed as standard practice. Then, all the pre-, intra-, and post-procedure data patients will be collected in a database. Investigators aim to perform a prospective, single-center, investigator-initiated, randomized study to compare the Adenosine-induced coronary vasodilatation after the loading dose of Ticagrelor either Clopidogrel during the Percutaneous Coronary Intervention. Patients with Acute Coronary Syndrome undergoing Percutaneous Coronary Intervention will be enrolled in the study and will be randomized, in a 1:1 ratio, to receive a loading dose of Ticagrelor (180 mg) or Clopidogrel (600 mg). Coronary Flow Reserve will be recorded by intracoronary Doppler Flow Wire before the stent implantation and after the procedure at baseline and 2-minute later adenosine intravenous administration at incremental doses of 50, 80, 110 and 140 ug/Kg/min with 2 minutes interval between infusions. Coronary Flow Reserve is the ability of the myocardium to increase blood flow in response to maximal exercise. Doppler Flow Wire allows to measure this increase expressing it as a ratio between maximal vasodilation and flow at rest. Coronary Flow Reserve is routinely measured in patients with Acute Coronary Syndrome, without an increased risk of adverse events for patients neither adjunctive costs for the National Health System. Furthermore, Plasma concentrations of Ticagrelor and its main metabolite (AR-C124910XX) will be measured in venous blood collected at the end of the procedure. In patients requiring a second Percutaneous Coronary Intervention, for example for multivessel disease, all these measures will be repeated in the same manner.

Study design Investigators aim to perform a prospective, single-center, investigator-initiated, randomized study to compare the Adenosine-induced coronary vasodilatation after the loading dose of Ticagrelor either Prasugrel during the Percutaneous Coronary Intervention. Patients with acute coronary syndrome undergoing Percutaneous Coronary Intervention will be enrolled in the study and will be randomized, in a 1:1 ratio, to receive a loading dose of Ticagrelor (180 mg) or Prasugrel (60 mg). In patients with non-ST elevation myocardial infarction these drugs will be administered only when the coronary anatomy will be known, to avoid bleeding due to prasugrel, in patients suitable for coronary artery bypass grafting as recommended by European Society of Cardiology guidelines (Class IB) (10). In patients with ST elevation myocardial infarction, instead, prasugrel and ticagrelor will be administrated before the procedure, according to the European Society of Cardiology guidelines (Class IB) (11). Coronary Flow Reserve will be recorded by intracoronary Doppler Flow Wire before the stent implantation and after the procedure at baseline and 2-minute later adenosine intravenous administration at incremental doses of 50, 80, 110 and 140 ug/Kg/min with 2 minutes interval between infusions.

Multicenter Cohort of STEMI Patients

STEMI - ST Elevation Myocardial Infarction

Ischemic heart disease is the leading cause of mortality with 7.2 million of death in industrialized countries (WHO data). Myocardial infarction corresponding to acute occlusion of a coronary artery is the most brutal form and the more severe ischemic myocardial disease. Every year in France, about 60,000 Myocardial infarctions hospitalized, 30,000 are diagnosed remotely and 30,000 are revealed by an inaugural sudden death. Although mortality from myocardial decreased by 30% over the past decade, the prognosis is pejorative and difficult to assess precisely. The management of the patient depends on these factors, and justifies an active search on these topics, including the mechanisms of the deleterious ventricular remodeling, myocardial inflammation, reperfusion injury which determines in particular the evolution to heart failure. Cohorts of patients with myocardial infarction are rare but can be very valuable by their clinical, laboratory and imaging well documented. They are the source of new hypotheses for research or interventions as well as the quality of care assessment tool. The main objective of this project is to identify new markers: biological and imaging, treatment response and prognosis after acute myocardial infarction. Secondary objectives of the HIBISCUS-STEMI cohort to establish a clinical database, completed by biological samples and by imaging data that can be used in the following areas: Descriptive epidemiology of myocardial infarction and myocardial reperfusion Pharmacoepidemiology and treatments observatory: safety, efficacy, indication of treatment in real life, costs Assessment of the long-term effect of the treatment on the occurrence of heart failure and sudden death Quality of life and personal consequences, family, professional and social myocardial infarction Research of new diagnostic and prognostic biomarkers Research projects (e.g. risk of developing kidney failure or stroke in patients with myocardial infarction compared to the general population).

Pan-Cardio-Genetics Clot Assessment in Acute Coronary Syndromes

STEMI - ST Elevation Myocardial InfarctionThrombi1 more

Acute myocardial infarction with ST elevation (STEMI) is one of the leading causes of mortality. Although the presence of thrombus in STEMI patients has been linked to adverse outcomes, routine thrombus aspiration has not been proven effective. A potential explanation could be that patients with STEMI should be risk-stratified. Thus, a more personalized approach in treating these patients is stressfully required. This proposal aims to establish the required interdisciplinary infrastructure for developing a risk-stratification model by implementing clinical, laboratory and angiographic data with molecular knowledge obtained by using innovative technologies, such as data from nano/micro-Computed tomography and circulating microRNAs. Two hundred consecutive patients with STEMI undergoing thrombus aspiration will be enrolled in the study and will be followed-up for one year for Major Adverse Cardiac and Cerebrovascular events (MACCE). The proposed approach will shed light on the pathophysiological mechanisms and broaden the investigator's understanding of the complex cellular and molecular interactions in the STEMI setting that, along with clinical parameters, affect patient outcomes. Furthermore, it will enable the identification of certain circulating micro-RNAs as cardiovascular disease biomarkers and it will help clinicians to better stratify the cardiovascular and cerebrovascular risk of patients with STEMI. As part of the work, important characteristics of aspirated thrombi will be assessed for the first time (such as volume, density and shape) and will be linked to patient outcomes. All this information will be incorporated into one in-vitro model, which will be developed using bioprinting and microfluidics methodologies. The in-vitro model will facilitate: (i) the in-depth exploration of the pathophysiological mechanisms in patients with STEMI; and (ii) the therapeutic optimization of innovative nanocarriers/nanomedicines with thrombolytic efficacy. Clearly, the study improves personalized cardiovascular medicine approaches, by considering individual patient clinical assessment in a way that empowers the precision in diagnosis and therapy.
