Active clinical trials for "ST Elevation Myocardial Infarction"

This is a multicentre observational study planned to gather follow up data for a period of 1 year in order to understand the treatments and outcomes of ST-segment elevation myocardial infarction(STEMI) and improve medical care quality in Fujian province for China. Consecutive patients who were admitted and diagnosed with STEMI between January 2014 December 2018 were conducted at five regional representative hospitals in Fujian province, which included the Fujian Provincial Hospital,Longyan First Hospital, the affiliated hospital of putian university,the Second Affiliated Hospital of Fujian Medical University and Mindong Hospital of Ningde City.

The study intends to provide new data on whether the noval method using quantitative flow ratio could assess microvascular dysfunction based on the previous study EARLY-MYO-QFR-I.

The investigators want to assess the use of the residual SYNTAX score and the SYNTAX Revascularization Index as predictors for in-hospital outcomes and mid-term (6 months to 1 year) outcomes in patients with multi-vessel disease (MVD) who undergo PCI in the setting of STEMI or NSTEACS. Both values will be calculated in a number of patients over one year, and the relationship between both values and patient outcomes will be evaluated.

The aim of the study is to investigate the impact of an initial non-specific / non-cardiac diagnosis on mortality among patients hospitalised with acute myocardial infarction.

RAND/UCLA modified Delphi study on quality indicators for STEMI to determine the appropriateness of quality indicators retrieved from literature and guideline review. We aim to engage 20 cardiologists and 20 nurses with relevant experience in the care for STEMI patients.

Although the pre-procedural neutrophil to lymphocyte ratio (N/L) has been associated with adverse outcomes among patients with coronary artery disease, its role during the acute phase of ST-segment elevation myocardial infarction (STEMI) has not been fully investigated. This study sought to investigate the association of the pre-procedural N/L ratio within-hospital and long-term outcomes among STEMI patients undergoing primary percutaneous coronary intervention (PCI).

The primary objective of this study is to determine if the Smartphone electrocardiogram (ECG) is an acceptable replacement for a standard ECG in the identification of ST Elevation Myocardial Infarction (STEMI). Toward this objective, this study involves the following: Obtain simultaneous recordings of a standard 12-lead ECG and the iPhone "12-lead equivalent" ECG on patients presenting with chest pain in which the STEMI protocol was activated. Obtain simultaneous recordings of a standard 12-lead ECG and the iPhone "12-lead equivalent" ECG on patients presenting to the Emergency Department for evaluation of chest pain, not necessarily presenting with STEMI. Reading of ECGs (standard 12-lead and iPhone) by three independent cardiologists, who are blinded to the initial clinical ECG readings, the type of ECG equipment used, and the patient's clinical information. Assess the operational feasibility of using the Smartphone to obtain "12-lead equivalent" ECG recordings in patients suspected to have STEMI, and Determine the possibility of pooling the data obtained from this study with data from other institutions conducting identical studies, and developing a future IRB-approved protocol and statistical analysis plan to compare the sensitivity, specificity, positive predictive value and the negative predictive power of the iPhone ECG, using a paired standard 12-lead ECG as the gold standard. There will be no therapeutic interventions. A single research-related procedure will be required, i.e. an iPhone ECG. Effort will be made to ensure that the performance of this procedure will not delay any treatment and/or diagnostic procedures that are part of usual or specialized care that the patient requires. Effort will be made to enroll 1 STEMI patient for every 2 non-STEMI patients.

OPTAMI documents the characteristics of consecutive patients with acute STEMI and NSTEMI in hospital everyday-life in Germany, their acute and adjuvant medication treatment, events until discharge (e.g. mortality, stroke, re-MI), and their medication for secondary prevention at discharge. In the follow up-period of one year, information is collected concerning events as mortality, stroke, re-MI, coronary interventions (PCI, CABG) and re-hospitalisation. The implementation of guideline-adjusted therapy in hospital everyday-life is reviewed. The usefulness of the European standard for data acquisition in cardiology (CARDS = Cardiology Audit and Registration Standards) is evaluated.

EUROTRANSFER Registry is a prospective, international, web-based European Registry on Patients with ST-Elevation MI Transferred for Mechanical Reperfusion (PCI) with a Special Focus on Upstream Use of Abciximab. This registry is designed to collect data on approximately 1800 patients during a 12 month enrollment period in up to 20 interventional cardiology centres with hospital transfer networks from all over Europe. Analysis of this registry should allow to monitor transfer timelines of patients arriving to the cath-lab from the regional hospital with or without upstream start of abciximab and scheduled for mechanical reperfusion (PCI) as well as to monitor regional differences across Europe in regard to the impact that time of various stages of the treatment chain may have on clinical outcomes.

ST-elevation myocardial infarction (STEMI) has a serious health threaten to population. PCI, which can timely restore the blood flow to the ischemic myocardium, is a well-proved measure in STEMI management. However, the process of the restoration can induce injury. The phenomenon is defined as ischemia/reperfusion (I/R) injury. The studies indicate that I/R injury accounts for up to 50% of the final myocardial infarct size. However, previous attempts to target known mediators of myocardial I/R injury in patients have been disappointing, leading to calls for a reevaluation of factors affecting myocardial I/R injury [1]. Arginine vasopressin (AVP), that response to acute illness, is unstable and cleared rapidly from the circulation. However, copeptin, the C-terminal portion of provasopressin, is released in equimolar amounts to AVP and is easy to determine. So, copeptin can be a surrogate marker for AVP secretion. Recently, copeptin was found to serve as a potential prognostic biomarker in heart failure and acute myocardial infarction (AMI). AMI can activate the AVP axis, which have a causative role in the evolution of heart failure. Increasing copeptin was shown to correlate with myocardial remodeling, mortality and morbidity. In patients with STEMI, myocardial infarct size is a stronger outcome predictor than LV function, and is related to LV remodeling, which often indicates a significant worse prognosis after AMI. As the gold standard for characterisation of cardiac structure and function, cardiac magnetic resonance (CMR) parameters can serve as surrogate end points in clinical trials of STEMI. We hypothesised that plasma copeptin values, tested before and after PCI, are related to myocardial infarct size, myocardial function both and outcomes at baseline and 6 months follow-up as assessed by CMR in patients with STEMI.
