Active clinical trials for "Myocardial Infarction"

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.

To provide insight into why vitamin D levels at baseline predict an adverse outcome including hospitalisation, we will establish whether baseline vitamin D levels are an independent marker of LV remodelling in patients experiencing an ST segment elevation myocardial infarction.

This is a multi-institutional registry database for the patients with stroke and cerebrovascular diseases. Stroke is the second leading cause of death in the Egypt. Despite extensive research, most of the patients die or suffer from varying degree of post-stroke disabilities due to neurologic deficits. This registry aims to understand the disease and examine the disease dynamics at the National Level. additionally it aim to introduce an objective method for classifying the registered hospital on a spectrum of 6 level coded with colors (from Black to Green ) according the availability of the predetermined 5 bundles of services presented for patient

Aim of this study is to describe clinical and procedural characteristics of real-world population initiated on triple antithrombotic therapy (double antiplatelet therapy+anticoagulant) or double antithrombotic therapy (single antiplatelet therapy+anticoagulant) after percutaneous coronary intervention (PCI). Investigator's driven trial, retrospective (2015-2019), multicenter Italian registry. Baseline clinical characteristics as well as procedural details will be collected retrospectively. Follow-up data (minimum 6 months and maximum 5 years follow-up) will focus on combined rates of stent thrombosis and myocardial infarction (primary endpoint).

The BioFreedom BA9 (Stainless Steel) Drug Coated Stent is an approved stent that is already commercially available in Europe and Asia. The purpose of this registry is to assess the safety and efficacy of the BioFreedom stent for treatment of a specific group of patients; patients with a myocardial infarction (STEMI). The objective is to capture patients' outcomes and antithrombotic strategies data using one or several BioFreedom Stents in the routine treatment of these STEMI patients.

Functional assessment of non-culprit lesions during percutaneous coronary intervention (PCI) in patients with acute coronary syndrome could improve risk stratification and long-term prognosis. It was previously demonstrated the diagnostic accuracy of instantaneous wave-free ratio (iFR) in functional assessment of non-culprit lesions in multivessel patients with ST-segment elevation myocardial infarction (STEMI), also highlighting the intralesional reproducibility of both fractional flow reserve (FFR) and iFR between baseline and staged. In this study the investigators aimed to verify the clinical impact on long-term outcome of iFR assessment in the acute multivessel setting.

Major adverse cardiac events (MACE) are a leading cause of mortality in patients undergoing noncardiac surgery. Patients with perioperative myocardial injury (PMI), defined as either myocardial infarction and lower elevations in cardiac troponin, are also at substantially increased risk of additional cardiac and noncardiac complications. Accordingly, it is plausible to assume that PMI negatively affects quality of life in terms of disability. The aim of this study is to investigate and compare the independent prognostic effects of the different PMI phenotypes (myocardial infarction and non-infarct troponin elevations) and noncardiac complications on disability in patients undergoing elective noncardiac surgery.

To compare the ST segment resolution after primary percutaneous coronary intervention (PPCI) with and without thrombus aspiration in patients with ST segment elevation myocardial infarction as ST segment resolution is the best indicator for the prediction of the outcome and MACE

This study aims to determine whether thyroid hormone levels are predictive of cardiac remodeling following myocardial infarction and the prognosis in patients with STEMI receiving primary percutaneous coronary intervention.

The current COVID19 pandemic has afflicted almost the whole globe. The stress related to the pandemic, not the direct virus-related injury, can be potentially associated with acute cardiovascular events due to a large list of physical and psychosocial stresses. This study is a cross sectional study that will enroll patients evaluated during the COVID19 pandemic period for acute cardiovascular events.
