Filter by:The purpose of the OPTIMISER Registry is to prospectively and retrospectively collect baseline, clinical and procedural data in patients who present with AMI and are treated with PCI as well as prospectively collect the clinical outcome data. Outcomes will be compared in different clinical subgroups. The impact of PCI in AMI in general as well as cardiovascular outcomes after AMI will be assessed.
An investigator-initiated, randomized, multicenter, two-arm, open-label study of consecutive patients presenting with STEMI and MVD Objectives: The present study aimed to investigate the difference in all-cause mortality after in-hospital staged PCI versus out-hospital staged PCI for ST-segment elevated myocardial infarction （STEMI）patients with multi-vessel Disease（MVD） Background: In primary percutaneous coronary intervention for STEMI with MVD, complete revascularization has proved to reduce the risk of cardiovascular death and myocardial infarction. However, a strategy of nonculprit-vessel PCI with the goal of complete revascularization still not to be confirmed. Compare with in-hospital staged PCI, out-hospital PCI as a strategy of nonculprit-vessel PCI for STEMI patients with MVD might have be beneficial results.
The primary objective of the PERI-STEMI trial is to assess whether sacubitril-valsartan is more effective in preventing adverse LV remodeling for patients with ST-elevation myocardial infarction (STEMI) than enalapril.
It is planned to include 200 patients hospitalized with primary myocardial infarction with and without ST segment elevation (STEMI or NSTEMI) in combination with COVID-19 within the first 15 days from the disease onset. The total follow-up period is 96 weeks. Hypotheses: 1. An integrated approach in assessing myocardial contractility, regulation of the heart and the structural and functional state of arteries will make it possible to more accurately assess the heart pumping function; explain the mechanisms of the relationship between left ventricular (LV) contractile function and its volumetric indices; to study the mechanisms of ventriculo-arterial coupling and the influence of autonomic regulation, the role of markers of the sudden cardiac death (late ventricular potentials, pathological turbulence of the heart rate, dispersion of the QT interval). 2. In patients who have had myocardial infarction in combination with the new coronavirus infection SARS-CoV-2 (COVID-19), long-term highly effective lipid-lowering therapy, regardless of the drugs prescribed, has an antiarrhythmic effect and has a beneficial effect on the autonomic regulation of the heart rate. Highly effective lipid-lowering therapy leads to an improvement in LV contractility and structural and functional properties of the large arteries. Methods and variables 1.

A multi-center, prospective randomized (1:1) pilot and feasibility study to evaluate the safety and feasibility of supersaturated oxygen (SSO2) therapy delivered for 60 minutes selectively into the culprit coronary artery of patients presenting with ST elevation myocardial infarction and cardiogenic shock (STEMI-CS) treated using a shock protocol.
To assess the effect of FDY-5301 on cardiovascular mortality and acute heart failure events in subjects with an anterior STEMI undergoing pPCI.
Left ventricular thrombus is a recognised complication of acute myocardial infarction, associated with stroke, recurrent myocardial infarction and adverse cardiac remodelling. The prevention, treatment and resolution of thrombus is hampered by a lack of understanding of its initiation, propagation and dissolution. Advanced non-invasive imaging holds major promise in improving our understanding of the incidence and the natural history of left ventricular thrombus as well as providing potential biomarkers to assess disease activity and treatment efficacy. In this prospective observational study, the investigators will recruit patients with recent acute anterior myocardial infarction and screen them for evidence of left ventricular thrombus and subclinical stroke using hybrid positron emission tomography and magnetic resonance imaging (PET/MR). Each patient will undergo PET/MR of the heart and head 7±2 days after acute myocardial infarction. If left ventricular thrombus is present on baseline MR, patients will be started on anticoagulation at the discretion of the attending physician, who will determine the agent used (warfarin or direct oral anticoagulant) and the duration of therapy (3-6 months). Patients will then undergo repeat PET/MR at completion of anti-coagulant therapy and then again after another 3 months. Patients with increased 18F- GP1 activity but no overt thrombus on MR will undergo repeat PET/MR of the head and heart at 3 and 6 months to establish the natural history of this observation and its association with thromboembolism in the brain. They will not routinely receive anticoagulation given the exploratory nature of this study.
Recovering blood flow to a coronary stenosis may improve left ventricular (LV) function in patients with coronary artery disease (CAD). However, the reported data about evaluation of LV function post-percutaneous coronary intervention (PCI) in CAD was limited. The aim of this study was to compare the LV function measured by 3 min low dose exercise stress echocardiography (ESE) combined 2D speckle tracking echocardiography (STE) in patients with CAD underwent PCI, and to identify factors affecting the change of LV function. Patients with CAD who underwent acute PCI were enrolled.
The RIC-AFRICA trial is a multi-centre, sham-controlled, double-blinded, randomised controlled trial (RCT) involving 1200 ST-segment elevation myocardial infarction (STEMI) patients presenting within ≤ 24 hours of myocardial infarction (MI) onset, across approximately 20 sites in four sub-Saharan African countries (South Africa, Kenya, Sudan and Uganda). Patients presenting with STEMI and deemed ineligible for the RIC AFRICA RCT because they present >24 hours from MI onset but less than 72 hours, will be recruited into the observational arm of the study with the same endpoints as the trial. The purpose of the RCT is to determine whether Remote Ischaemic Conditioning (RIC) can reduce the rates of all-cause death and early post-myocardial heart failure at 30-days in STEMI patients treated predominantly with thrombolytic therapy.
A multi-center randomized post-approval evaluation of delivery of intracoronary hyperoxemic supersaturated Oxygen therapy for 60 minutes in anterior AMI patients with successful reperfusion (via PCI) within 6 hours after onset of symptoms compared to standard therapy
