Active clinical trials for "Myocardial Infarction"

This non-interventional, ambispective study was aimed at evaluating the effectiveness, safety, and tolerability of bisoprolol and perindopril SPC in previous myocardial infarction patients with HTN and CAD treated with the drug for 12 weeks in the daily clinical practice. SPC will be used according to the approved instruction for medical use of the medicine. This is a multi-centre, observational, incomparative, ambispective study, which will retrospectively and prospectively collect clinical variables and socio-demographic data from medical records of patients with HTN and previous MI initiated with bisoprolol/perindopril SPC in real life settings.

The aim of HYBRIDHEART study is to develop new imagistic prototype for a complex evaluation of the myocardial viability by superposing computed tomographic angiographic polar maps of the myocardium with magnetic resonance imaging contractile maps in subjects who suffered an acute myocardial infarction. Moreover, the study will evaluate the association of myocardial viability with the level of inflammatory markers and the percent of myocardial fibrosis, also will correlate the imaging-derived parameters with the inflammatory status of the patients, left ventricular function, ischemic time and major adverse cardiovascular events (MACE) rate.

Myocardial infarction (MI) remains one of the most common causes of death. Percutaneous coronary intervention (PCI) is the main treatment option to restore blood flow through the infarction-related coronary artery (IRA) in MI patients. Performing PCI significantly reduces mortality, but in 5-10% cases, PCI is complicated by the development of coronary microvascular obstruction (CMVO, "no-reflow"). CMVO is defined as the absence of adequate myocardial perfusion, despite the restoration of the IRA lumen. The development of CMVO significantly worsens the prognosis and increases mortality. CMVO has a complex pathogenesis and is development due to following mechanisms: distal microembolism, ischemia-reperfusion injury, persistent endothelial dysfunction, and individual predisposition. These mechanisms can be implemented simultaneously and have different severity. The most significant predictors of CMVO occurrence are: age, time from pain onset to reperfusion, severity of acute heart failure, ineffective thrombolytic therapy, collateral blood flow according to the Rentrop classification, severity of IRA thrombosis according to Thrombolysis in Myocardial Infarction (TIMI) thrombus grade, initial IRA blood flow according to TIMI flow grade, implantation of 3 or more stents, direct IRA stenting, neutrophil and blood glucose levels. Difficulties in CMVO predicting are caused by the pathogenetic heterogeneity of this complication. Even the best models are moderately accurate. This can be explained by the fact that the models don't use genetic factors that determine endothelial function, microcirculation, hemostasis, and inflammation. Identification of the genetic determinants of the CMVO development can help create a new diagnostic system for CMVO predicting.

This study aims to evaluate if the 1-hour rule-in/rule-out algorithm for a high-sensitivity cardiac troponin T (hs-cTnT) is safe and effective for use in the primary care where the patients have a lower pretest probability of an acute myocardial infarction (MI). During this study troponins will be collected at 0-, 1- and 4/6-hours, where absolute changes in the values will decide whether the patient need hospitalization or not.

This study aims to investigate the association between active transport and the incidence of acute myocardial infarction in England.

The "EUropean Comparative Effectiveness Research to assess the use of primary prophylacTic Implantable Cardioverter Defibrillators (EU-CERT-ICD)" is a modular research project to study the effectiveness of prophylactic ICDs in a prospective study, a retrospective registry, and meta-analyses of existing evidence on the subject.

An adverse event (AE) is defined as unintended injury or complication, which results in disability, death or prolongation of hospital stay, and is caused by healthcare management (including omissions) rather than the patient's disease. Retrospective record reviews in several countries have shown that 2,9% to 16,6% of patients in acute hospitals experience one or more AEs. A patient with an AE may require a higher level of care. Although all AEs are important, preventable AEs that result in an upgraded level of patient care are of particular concern. In this study it's defined as an unplanned admission to intensive care unit (ICU) or a Mobile Emergency Team (MET) intervention. The objectives of this study are to determine the incidence of (preventable) adverse events requiring ICU admission or MET intervention and to assess the level of harm of each AE.

This study is to build a Chinese national registry and surveillance system for acute myocardial infarction(AMI) to obtain real-world information about current status of characteristics, risk factors, diagnosis, treatment and outcomes of Chinese AMI patients; And to propose scientific precaution strategies aimed to prevent effectively from the incidence of AMI; And to optimize the management and outcomes of AMI patients through implementation of guideline recommendations in clinical practice, and analysis and development of effective treatment strategies; And to create cost-effective assessment system.

Purpose: The purpose of this study is to evaluate the impact of circulating miR-126 on left ventricular remodeling and clinical outcomes in patients undergoing primary percutaneous coronary intervention for ST-segment elevation myocardial infarction.

The purpose of this study is to determine whether preoperative loading dose atorvastatin can prevent perioperative myocardial infarction during angiography and main adverse cardiac events 1 month after operation in stable angina, unstable angina and acute non-ST-segment elevation myocardial infarction patients undergoing elective coronary angiography and PCI, and determine whether its mechanisms are associated with microcirculation resistance.
